1. Introduction
What justifies regulating hate speech in democratic societies?Footnote 1 Whether and how to regulate hate speech has been a subject of controversy for decades among jurists, activists, and political theorists around the world (Baker, Reference Baker1989; Post, Reference Post1991; Coliver, Reference Coliver1992; Matsuda et al., Reference Matsuda, Lawrence, Delgado and Crenshaw1993; Weinstein, Reference Weinstein1999; Lewis, Reference Lewis2007; Hare and Weinstein, Reference Hare and Weinstein2009; Herz and Molnar, Reference Herz and Molnar2012). In many countries, including the UK, Canada, and Germany, laws have been established to regulate and penalize hate speech, but their legislative contents vary considerably in what sort of act against whom should be regulated as well as the severity of applicable criminal sanctions.Footnote 2 In the USA, there is no equivalent law, as free speech is most ardently protected by the First Amendment to the US Constitution with courts only allowing for so-called ‘content-neutral’ restrictions (Stone, Reference Stone1987); this regulatory absence is often described as ‘exceptionalism’ (Krotoszynski, Reference Krotoszynski2006) or ‘American way’ (Rosenfeld, Reference Rosenfeld2003) in constitutional approaches to hate speech.Footnote 3 Given the enduring disagreement and observed variety, it must be tempting for scholars to drift away from a quest for a uniform theory on hate speech regulations. Indeed, the author of a recent review article suggests that ‘the largely muddled debate over hate speech needs to be broken down into discrete analytical stages’ (Howard, Reference Howard2019: 95).Footnote 4
How can one challenge this seeming theoretical inertia? In this paper, we revisit an argument advanced by Jeremy Waldron in his acclaimed book, The Harm in Hate Speech (Waldron, Reference Waldron2012b). At the core of his thesis lies the distinction between the two kinds of harm that hate speech may incur against the targeted individual, namely ‘undermining dignity’ and ‘causing offense.’ According to Waldron, offense, ‘however deeply felt, is not a proper object of legislative concern,’ since it is ‘inherently a subjective reaction,’ and the law in modern era is never meant to protect anybody's feelings. Dignity, on the other hand, merits due protections; ‘not dignity in the sense of any particular level of honor or esteem (or self-esteem), but dignity in the sense of a person's basic entitlement to be regarded as a member of society in good standing.’Footnote 5 In this respect, the harm done against the individual by undermining his/her/their dignity becomes the harm done to the ‘public good’ of that society, the provision of which must be assured by law even as balanced against the importance of free speech principle.Footnote 6
We seek to augment this normative argument, now referred to as ‘dignitarian rationale’ or simply ‘dignitarianism’ in the literature, by demonstrating, through comprehensive empirical evaluations, that the concept of dignity does serve as the cornerstone for justifying regulations of hate speech. For this task, we take advantage of the data from a survey we conducted among ordinary Japanese citizens in 2018. As explained below, Japan then, having only recently (in 2016) adopted the nation's first anti-hate speech law, was like an incubating ground where norms and interpretations on the subject were in the making. This setting provided a uniquely suited opportunity for our research, unlike Canada and European countries where the regulations had already been in place for some time, and unlike the USA where the opinions for and against governmental regulations are so deeply entrenched in the respective ideological camps. Moreover, Japan offers an additional advantage for our purpose in that, because of the relative homogeneity of its population compared with other countries, few survey respondents would be expected to belong to minority group, that is, potential target of hate speech. This provides us with an ideal situation for examining the attitudes of ordinary citizens toward hate speech regulations. To be specific, in Japan, the most widely reported victims of hate speech are Koreans residing in Japan (Zainichi Koreans); it is estimated that they constitute less than 0.5% of Japan's entire population.
We design our survey, most importantly, to juxtapose and test the relative significance of the perceived level of ‘offense’ and that of ‘indignity’ caused by hate speech as potential sources for respondents’ support for hate speech regulations. Our findings confirm that respondents' concerns about the dignity of a targeted victim lead them to support regulations far more strongly and consistently than their concerns over whether the victim is offended. After verifying this, our research design further allows us to explore possible causal pathways through which these perceptions affect their regulatory attitudes. Such an analysis consolidates the bridge between normative theorization like Waldron's and our own empirical findings, clarifying the underlying psychological mechanism at work for ordinary citizens who support hate speech regulations. In the dignitarian discussion, it is simply assumed that the degrading of the society, and hence the erosion of the ‘public good,’ constitutes regulatory justification, but this claim has never been subject to empirical scrutiny. It turns out, according to our mediation analysis, that ordinary citizens' regulatory attitudes are shaped not only by such concerns for societal consequences but also by their intrinsic senses of justice and morality. Although the external validity of our findings is ultimately confined to the Japanese case at hand, the implications drawn from the analysis in this paper do speak to the generalizability of the dignity-based argument, which, in our conclusion, provides an important insight, if not the basis, for any discussion on hate speech regulations.
The rest of this paper is organized as follows. In Section 2, we highlight the main characteristics of the dignitarian rationale by reviewing Waldron's original discussion with some critical annotations. Section 3 reviews extant empirical approaches to hate speech. Section 4 presents testable hypotheses. Sections 5 and 6 describe our research design and findings. Section 7 concludes by drawing broad implications and pointing to directions of future research.
2. Dignitarianism and its critics
In any democracy, particularly under the American context where the vast First Amendment jurisprudence has accumulated, it would be controversial to claim that certain speech and speech acts, be it hate speech aimed at minorities, publications of pornography, or the spreading of so-called ‘fake news’ through the internet, should be banned because they are unworthy of protection by the principle of free speech. In advancing his defense for hate speech regulations, Jeremy Waldron does not make such a claim. He is a consequentialist and rather sees the matter from a balancing perspective: ‘We recognize, in general, that the considerations which argue in favor of the broad importance of free-speech do extend to speech attempting to stir up racial or religious hatred; but we say nevertheless such speech must be regulated, and in extreme cases prohibited because of the harm it does’ (Waldron, Reference Waldron2012b: 147, emphasis original). But this position, of course, begs the question: what harm?
In actuality, the harm caused by hate speech can and do take various forms, as identified and listed elsewhere in the previous literature (e.g., Delgado, Reference Delgado, Matsuda, Lawrence, Delgado and Crenshaw1993; Brown, Reference Brown2015). Hence, any plausible justification for regulating hate speech must be premised on a well-reasoned argument that not only discerns different aspects of the harm caused but addresses their respective behavioral and regulatory implications. For example, an approach that exclusively focuses on physical aspects of the harm caused by hate speech would not constitute a distinct justification, since such an approach would be equating the act of hate speech with assault. Alternatively, an approach that excessively emphasizes psychological aspects of the harm caused by hate speech would be difficult to serve as a viable regulatory justification, because of subjective elements inherent in human feelings and attitudes which are bound to vary considerably across individuals.
In this context, Waldorn's approach stands out in the literature for its innovative and nuanced prodding, as he draws the crucial distinction between the two likely consequences that hate speech may incur against the targeted individual: ‘undermining dignity’ and ‘causing offense.’ This distinction, he explained, ‘is in large part between objective or social aspects of a person's standing in society and subjective aspects of feeling, including hurt, shock, and anger’ (Waldron, Reference Waldron2012b: 106). Waldron argues that the latter does not justify regulations, since the modern laws are never meant to protect anybody's feelings. The former, however, provides the cornerstone for hate speech regulations, because a ‘democratic society cannot work, socially or politically, unless its members are respected in their character as equals, and accorded the authority associated with their vote and their basic rights’ (Waldron, Reference Waldron2012b: 109). Thus, Waldron's dignity-centered argument marks a departure from the orthodox liberal tradition, advancing the agenda of hate speech regulations from simply a matter of balancing individual rights to something that involves ‘public good’ at stake.Footnote 7
Dignitarianism, of course, has since been criticized. The criticisms range from the most predictable First-Amendment advocacy (e.g., McConnell, Reference McConnell2012) to a more sophisticated counter-argument that restriction of free speech would weaken democratic legitimacy (cf. Dworkin, Reference Dworkin, Hare and Weinstein2009, Reference Dworkin, Hertz and Molnar2012; Weinstein, Reference Weinstein2017), and to nuanced assessments which, while basically sympathetic, point to some specific weaknesses in its logic, such as the inability to make a stronger causal argument (Barendt, Reference Barendt2019) or its failure to account for social hierarchy (Simpson, Reference Simpson2013).Footnote 8 None, however, to our knowledge, has ever questioned the validity of the distinction between offense and indignity. The absence is surprising because the dignitarian rationale for regulating hate speech is premised upon this distinction. Even when some critics point out that making such distinction deems difficult (e.g., Leiter, Reference Leiter2012: 6–7), the issue is not pursued further, as if the difficulty is taken for granted by both sides of the debate.
Indeed, Waldron himself concedes the difficulty when he describes the seamless chain of reactions that take place in the mind of a targeted victim. By admitting this ‘psychological complexity,’ he is forced to acknowledge his inability to identify ‘the lawfulness and unlawfulness of certain speech acts on the basis of a case-by-case analysis’ (Waldron, Reference Waldron2012b: 113). How then can one confront two alleged victims and determine whether a punishable act was inflicted on one, both, or neither? Again, Waldron admits the difficulty, and by this time his defense becomes circular: ‘I am not proposing a complicated legal test for distinguishing hate speech from speech that merely offends. I am only suggesting that in defending (or arguing about) such a distinction, we should be willing to come to terms with psychological complexity’ (Waldron, Reference Waldron2012b: 115).
This retreat is problematic because the dignitarian argument that hate speech must be regulated when and only when it harms the target's dignity is not simply a philosophical proposition; it is also a policy proposal. It is one thing to uphold the importance of the conceptual distinction between indignity and offense in the abstract. To show such distinction can be utilized justifiably in drafting, implementing and adjudicating laws is quite another. Waldron does not theorize his argument on the basis of public support for it. We believe that it is this lack of behavioral foundation that limits the persuasiveness of his argument. If the dignitarian proposition is to be presented as a policy proposal in democratic societies, what enhances its plausibility must be direct evidence that a majority of citizens actually support the proposition/proposal. It is precisely such evidence that our survey aims to reveal.
3. Empirical approaches to hate speech
The empirical literature on hate speech extends over many academic disciplines, and our research is certainly not the first to take advantage of survey or survey-experimental methods. Social-psychologists, criminologists as well as scholars in racial and cultural studies have conducted numerous voluntary-based interviews and small-scale experiments in their respective fields. These previous studies, however, have focused on the actual or potential victims of hate speech, such as gays, lesbians, and bisexuals in California (Herek et al., Reference Herek, Cogan and Gillis2002), Jewish and gay students on college campuses (Leets, Reference Leets2002), Asian-American university students (Boeckmann and Liew, Reference Boeckmann and Liew2002), and indigenous and minority ethnic communities in Australia (Gelber and McNamara, Reference Gelber and McNamara2016). We maintain that an inquiry into the public support for governmental regulations of hate speech requires a sample of respondents that are randomly drawn from ordinary citizens in a given democratic society.
Our approach also differs from the previous studies in terms of the main dependent variable measure. Typically, as in the works of Gloria Cowan and her co-authors, psychological surveys and survey experiments include a battery of value-related questions to gauge their perception about the harm of hate speech along with their attitudes toward the principle of free speech (Cowan and Hodge, Reference Cowan and Hodge1996; Cowan et al., Reference Cowan, Resendez, Marshall and Quist2002; Cowan and Khatchadourian, Reference Cowan and Khatchadourian2003; Downs and Cowan, Reference Downs and Cowan2012). Since we are interested in the respondents’ legislative preference, we aim to measure directly their attitudes toward governmental regulations, while treating the perceived harms of hate speech and attitudes toward the principle of free speech as key explanatory variables and control variables, respectively. As far as we know, this is the first empirical research to explain ordinary citizens' attitudes toward hate speech regulations.
4. Hypotheses
Our survey investigates whether the dignitarian argument has an empirical foundation. To achieve this goal, we test the validity of several hypotheses. The first set of hypotheses speaks to the core argument of dignitarianism that hate speech should be regulated when it harms the target's dignity and not when it harms the target's feelings. For this argument to stand as a plausible policy or policy guideline in democratic societies, we need to observe the following two empirical patterns:
Hypothesis 1. Citizens’ attitudes toward hate speech regulations are shaped independent of how much harm they perceive is done to the victims’ feelings.
Hypothesis 2. Citizens’ support for hate speech regulations is higher when they perceive that the greater harm is done to the victims’ dignity.
To be sure, these two hypotheses are consistent with, but they are not logically derived from, dignitarianism, since the proponents of this normative theory do not elaborate on how the members of a democratic society think about hate speech regulations. The above hypotheses are presented here because we believe that their empirical tests serve as a touchstone for the feasibility of the dignitarian proposition.
If the empirical patterns consistent with Hypotheses 1 and 2 are confirmed, the next step is to ask why. To answer this question, we consider two possible explanations. The first explanation is originally offered by dignitarian theorists themselves, namely, the idea of ‘public good’: the government should regulate dignity-harming hate speech because such speech will move the society in a bad direction, whereas feelings-harming hate speech should not be regulated because such speech will not erode the ‘public good’ of the society. To examine whether ordinary citizens believe in the same way as this consequentialist logic, we test the following three hypotheses:
Hypothesis 3. Citizens’ belief that hate speech makes their society worse is shaped independent of how much harm they perceive is done to the victims’ feelings.
Hypothesis 4. Citizens’ belief that hate speech makes their society worse is stronger when they perceive that the greater harm is done to the victims’ dignity.
Hypothesis 5. Citizens’ support for hate speech regulations is higher when they more strongly believe that hate speech makes their society worse.
In addition to this original logic about societal consequences, we suspect that ordinary citizens may also be motivated to support hate speech regulations based on their intrinsic senses of justice and morality. This second reasoning can be considered as an ethics-driven, deontological (as opposed to consequentialist) mechanism: citizens believe that the government should regulate dignity-harming hate speech because such speech is intrinsically wrong and unjust (whereas feelings-harming hate speech is not). We thus contrast the above set of hypotheses with the following set of alternative hypotheses:
Hypothesis 6. Citizens’ belief that hate speech is unjust is shaped independent of how much harm they perceive is done to the victims’ feelings.
Hypothesis 7. Citizens’ belief that hate speech is unjust is stronger when they perceive that the greater harm is done to the victims’ dignity.
Hypothesis 8. Citizens’ support for hate speech regulations is higher when they more strongly believe that hate speech is unjust.
5. Research design
In this section, we describe the regulatory background in Japan where our survey was conducted, and then explain our sample and basic design.
5.1 Background
Our survey was conducted through internet with adult residents in Japan in March 2018, less than 2 years after Japan's parliament passed the bill called ‘The Act on the Promotion of Efforts to Eliminate Unfair Discriminatory Speech and Behavior against Persons Originating from Outside Japan.’Footnote 9 Prior to the enactment of this law, there had been no formal regulation on hate speech or hate speech act in Japan. The conservative political establishments, including senior members of the ruling Liberal Democratic Party as well as the Ministry of Justice, had long been reluctant to endorse any governmental regulation, which would infringe the constitutionally guaranteed right of free speech and expression.
A rather abrupt momentum toward establishing a new law was born, at least in part, in response to the increased pressures from the international community, especially from the United Nations, which came in the form of various reports and recommendations. It was in the spring of 2013 when The United Nations Committee on Economic, Social, and Cultural Rights for the first time acknowledged the existence of problems in this country by explicitly using the term ‘hate speech’ in its third periodic report on the implementation of the International Covenant on Economic, Social, and Cultural Rights. In the summer 2014, the two prominent organizations at the United Nations, The Office of the UN High Commissioner for Human Rights and The UN Committee on the Elimination of Racial Discrimination, expressed concerns over the rising racist demonstrations against ethnic Koreans residing in Japan (Zainichi Koreans).Footnote 10 It was only after the international pressure grew that the domestic media finally started to cover these demonstrations in its report; prior to 2013, even nationally circulated newspapers, such as Yomiuri and Asahi, had never used the word ‘hate speech’ in their printed articles. It can thus be assumed that the very concept of hate speech had not previously been known to ordinary citizens in Japan; even today, this concept is expressed in Katakana syllabary, a component of Japanese writing system specifically used for transcribing words of foreign language origins.
The enacted law is often criticized because of its exclusive focus on foreigners residing in Japan, particularly Zainichi Koreans. Hate speech against other potentially targeted minority groups, such as gays and lesbians, elderlies, people with disabilities, and holders of certain religious beliefs or political ideologies, are not covered by this legislation. Further, human-rights advocates have expressed their dissatisfactions with the law, particularly because it neither criminalizes any speech act nor includes specific enforcement procedures (cf. Kotani, Reference Kotani2018). These limitations notwithstanding, some prefectural and city governments in Japan have since used and relied upon the spirit of this national law to issue harder restrictions in their respective localities, sometimes establishing their own ordinances with criminal sanctions and extending the coverage of protections to other minority groups.
In sum, it is fair to characterize Japan in 2018, when our survey was conducted, as not having developed stable norms or interpretations on the subject of hate speech regulations: ordinary Japanese citizens were in the midst of developing new norms and interpretations on the subject. Japan then was like an incubating ground, which we believe provided a uniquely suited opportunity to engage our survey inquiry.
5.2 Sample
To administer our survey, we contracted with Nikkei Research, one of the major online survey companies in Japan. The company sent invitation emails to some of the people pre-registered at it and recruited 390 respondents for this research. A monetary incentive was provided in return for their participation, and the amount of money provided to each respondent was determined by the individual contract between the company and the respondent. A stratified random sampling procedure was used when sending out invitation emails so that the appropriate number was assigned to each category of gender and geographical regions in proportion to the actual demographic data reported in Japan's latest edition of Juminkihondaicho (Basic Residence Register).
Although invitation emails were sent randomly, the pool of pre-registered individuals from which our respondents were recruited is not a representative sample of the population. Due to the skewed distribution of internet users among the elderly, our sample is limited to those between 20 and 69 years of age. The median respondent in the sample is thus slightly younger than the median Japanese resident. It was also explained to us that, in comparisons with the actual population in Japan, the Nikkei Research samples are generally skewed to higher levels of income and education. We will discuss these data problems later in the paper.
To ensure that our analysis concentrates on valid responses from attentive survey takers, we included two attention-check questions in the survey to filter out inattentive respondents, or ‘satisficers.’ These questions were simple instructed-response items that anyone paying attention should be able to answer. Respondents were excluded from subsequent analysis if they answered either of these questions incorrectly. After filtering them out, we retain 309 respondents for our analysis.
5.3 Measurement
Our key explanatory variables are the perceived levels of offense and indignity that may influence the respondents’ attitudes toward hate speech regulations. To measure these variables, we asked them the following questions:
Recently in Japan, in some areas or on the internet, you can find hate speech, that is, insults and incitements to violence against Zainichi Koreans.
• Do you think such hate speech, that is, insults and incitements to violence, against Zainichi Koreans would make them feel offended? Or do you think that it would not make them feel offended?
• Do you think such hate speech, that is, insults and incitements to violence, against Zainichi Koreans would harm their dignity? Or do you think that it would not harm their dignity?
For each of these questions, the answer options were provided on a 5-point scale with larger values indicating greater perceived harms to the victims of hate speech. In the case of the question about the perceived harm to feelings, the options were: (1) Absolutely would not make them feel offended; (2) Probably would not make them feel offended; (3) Neither; (4) Probably would make them feel offended; and (5) Absolutely would make them feel offended. For the question about the perceived harm to dignity, the options were: (1) Absolutely would not harm their dignity; (2) Probably would not harm their dignity; (3) Neither; (4) Probably would harm their dignity; and (5) Absolutely would harm their dignity. The order of these two questions was randomized across the respondents. To ensure a consistent definition of Zainichi Koreans – the most frequent target of hate speech in Japan and the main group to which Japan's anti-hate speech law is intended to provide protection – a brief sentence was added in the vignette to explain who Zainichi Koreans are.Footnote 11
Figure 1 shows the distributions of as well as the correlation between the perceived harm to feelings and the perceived harm to dignity. One prominent feature of these two variables is that most respondents perceive that hate speech against Zainichi Koreans would harm their feelings (87%) and dignity (84%), respectively. Another key feature is a strong positive correlation between the two variables. For example, 85% of the respondents are on the 45-degree line. We emphasize here, however, that despite the strong correlation, the two variables in terms of their effects on the outcome and intervening variables turn out to be clearly distinguishable, as our empirical analyses below demonstrate.
Figure 1. Correlation between the perceived harm to feelings and the perceived harm to dignity.
For descriptive purposes, it may also be interesting to know what types of respondents perceive that hate speech causes offense and indignity, respectively. Table 1 shows the results of linear models that regress the perceived harms of hate speech on the respondent's gender, age, education, income, 11-point scale liberal-conservative ideology measure with greater values indicating conservative political positions, 4-point scale measure of free speech with greater values indicating that the respondent respects the freedom of speech more strongly, and relationship with victims of hate speech, that is, a binary variable of whether the respondent or persons close to him/her were victimized by hate speech. Interestingly, none of these covariates helps us explain variation in the perceived harm to feelings and the perceived harm to dignity, respectively.
Table 1. Sources of the perceived harms of hate speech
Note: Linear regression models are used. Robust standard errors are in parentheses.
*P < 0.05; **P < 0.01; ***P < 0.001.
The outcome variable in our research is the level of support for governmental regulations on hate speech. To measure this variable, we asked the respondents the following question:
Next, we ask you how the government should respond to this issue. Do you think that the government should impose restrictions on such hate speech, that is, insults and incitements to violence, against Zainichi Koreans? Or do you think that the government should not impose any restrictions?
For this question, the answer options were provided on a 7-point scale: 0 meaning ‘Should not impose any restrictions,’ 3 meaning ‘Cannot say one way or the other,’ and 6 meaning ‘Should impose thorough restrictions.’ Figure 2 shows the distribution of this variable. There are far more respondents who support hate speech regulations (57%) than those who do not (17%), but there are also a significant number of respondents who stand in the middle (25%).
Figure 2. Distribution of support for hate speech regulations.
As the intervening variables that may link the explanatory and outcome variables specified above, we contrast two possible mechanisms noted earlier, namely the societal-concern mechanism and the sense-of-injustice mechanism. We believe that these two possible mechanisms are not mutually exclusive, although the dignitarian rationale does not fully address the second pathway. In order to probe the saliency of the two mechanisms, we used the relevant questions included in our survey:
• What effect do you think such hate speech, that is, insults and incitements to violence against Zainichi Koreans would have on the Japanese society? Do you think it would move the Japanese society in a good direction or in a bad direction?
• Do you think such hate speech, that is, insults and incitements to violence against Zainichi Koreans would be just? Or do you think that it would be unjust?
For each of these questions, the answer options were provided on a 5-point scale with larger values indicating greater perceived harms. In the case of the question about societal concern, the options were: (1) Absolutely would make it worse; (2) Would rather make it worse; (3) Neither; (4) Would rather make it better; and (5) Absolutely would make it better. For the question about the sense of injustice, the options were: (1) Absolutely would not be unjust; (2) Would not rather be unjust; (3) Neither; (4) Would rather be unjust; and (5) Absolutely would be unjust. As shown in Figure 3, most respondents believe that hate speech against Zainichi Koreans would make the society worse (73%) and be unjust (70%), and societal concern and the sense of injustice are positively correlated with one another (61% of the respondents are on the 45-degree line).Footnote 12
Figure 3. Correlation between societal concern and the sense of injustice.
5.4 Models
To investigate how the respondents’ attitudes toward hate speech regulations is shaped by the perceived harms of hate speech, we use the following linear regression model:
where Z represents a set of control variables including the respondent's gender, age, education, income, ideology, attitude toward free speech, and relationship with victims of hate speech.
To examine the mechanisms underlying the associations between the explanatory and outcome variables, we follow the conventional procedure of mediation analysis, by fitting the following three linear regression models:
Model 2 investigates how the respondents’ societal concern is shaped by their perceived harm to feelings (α 1) and their perceived harm to dignity (α 2). Model 3 analyzes how the respondents' sense of injustice is shaped by their perceived harm to feelings (γ 1) and their perceived harm to dignity (γ 2). Model 4 explores how the respondents' regulatory attitude is shaped by their societal concern (β 3) and their sense of injustice (β 4) while adjusting for the unmediated association between the regulatory attitude and the perceived harm to feelings (β 1) as well as the unmediated association between the regulatory attitude and the perceived harm to dignity (β 2).
Since we use linear regression models, the association between the perceived harm to feelings and the attitude toward hate speech regulations mediated by the societal-concern mechanism is a product of α 1 and β 3; the association between the perceived harm to dignity and the attitude toward hate speech regulations mediated by the societal-concern mechanism is a product of α 2 and β 3; the association between the perceived harm to feelings and the attitude toward hate speech regulations mediated by the sense-of-injustice mechanism is a product of γ 1 and β 4; and the association between the perceived harm to dignity and the attitude toward hate speech regulations mediated by the sense-of-injustice mechanism is a product of γ 2 and β 4.
6. Findings
Column (1) of Table 2 shows how the attitude toward hate speech regulations is shaped by the perceived harm to feelings and the perceived harm to dignity, respectively. The respondents' perceived harm to feelings has no statistically significant association with their regulatory attitudes, whereas the association between the perceived harm to dignity and support for hate speech regulations is positive in a statistically significant manner. For example, a shift from the neutral view to the view that hate speech against Zainichi Koreans would absolutely harm their dignity is, on average, associated with a 1.39-point increase in the 7-point-scale measure of support for hate speech regulations. These results are consistent with Hypotheses 1 and 2, implying that the dignitarian argument that hate speech should be regulated when and only when it harms the target's dignity may be a feasible policy in democratic societies.
Table 2. Perceived harms, support for regulations, and mechanisms
Note: Linear regression models are used. Robust standard errors are in parentheses.
*P < 0.05; **P < 0.01; ***P < 0.001.
Having established a strong positive association between the perceived harm to dignity and support for hate speech regulations, we now proceed to the next ‘why’ question. While there may be numerous pathways that link these two variables, we contrast two mechanisms as described earlier: the societal-concern mechanism and the sense-of-injustice mechanism.
Column (2) of Table 2 shows results consistent with Hypotheses 3 and 4: while the respondents’ concerns over which direction the society is heading are shaped independently of their levels of the perceived harm to feelings, societal concern is positively and statistically significantly associated with the perceived harm to dignity. For example, a shift from the neutral view to the view that hate speech against Zainichi Koreans would absolutely harm their dignity is, on average, associated with a 1.22-point increase in the 5-point-scale measure of societal concern.
Column (3) of Table 2 shows results consistent with Hypotheses 6 and 7: the respondents’ beliefs that hate speech is unjust is shaped independently of their levels of the perceived harm to feelings, but the sense of injustice is positively and statistically significantly associated with the perceived harm to dignity. For example, a shift from the neutral view to the view that hate speech against Zainichi Koreans would absolutely harm their dignity is, on average, associated with a 1.23-point increase in the 5-point-scale measure of the sense of injustice.
Column (4) of Table 2 shows results consistent with Hypotheses 5 and 8: support for hate speech regulations is positively and statistically significantly associated with societal concern and the sense of injustice. For example, a shift from the neutral view to the view that hate speech against Zainichi Koreans would absolutely make the society worse is, on average, associated with a 1.42-point increase in the 7-point-scale measure of support for hate speech regulations. Similarly, a shift from the neutral view to the view that hate speech against Zainichi Koreans would absolutely be unjust is, on average, associated with a 0.51-point increase in support for hate speech regulations.
Figure 4 illustrates these results graphically. A unit increase in the perceived harm to dignity leads to a 0.611 unit increase in societal concern and a 0.613 unit increase in the sense of injustice. And, a unit increase in societal concern brings about a 0.709 unit increase in support for hate speech regulations. Also, a unit increase in the sense of injustice gives rise to a 0.253 unit increase in the level of support. Therefore, a unit increase in the perceived harm to dignity is associated with a 0.611 × 0.709 ≈ 0.433 unit increase in support for hate speech regulations through the societal-concern mechanism (with a 95% confidence interval of [0.219, 0.66]). It is also associated with a 0.613 × 0.253 ≈ 0.155 unit increase in the level of support through the sense-of-injustice mechanism (with a 95% confidence interval of [0.006, 0.34]).Footnote 13 Although the logic of societal concern has more explanatory power than that of the sense of injustice, both mechanisms are estimated to be statistically significant. This suggests that the original rationale presented by dignitarian theorists may be insufficient: the link between the perceived harm to dignity and support for hate speech regulations can be explained not only by the citizens’ concerns regarding the societal consequences but also by the alternative, ethics-driven logic based on their intrinsic senses of justice and morality.

Before concluding this section, we discuss some potential problems of our empirical investigation. We also report briefly some results from additional tests we performed for robustness checks.
First, the analyses presented above exclude from the sample satisficers, that is, the respondents who did not answer the attention-check questions correctly. We reanalyzed the regression models of Table 2 with the data including those ‘careless’ respondents, but the results did not change qualitatively except that the association between the sense of injustice and support for hate speech regulations loses its statistical significance (see Table A1 in the online Appendix). We leave to the readers the decision of which results are more convincing.
Second, our regression models include as control variables the respondents' liberal-conservative ideology measures and attitudes toward free speech, but these two variables may be shaped by their perceived harms to feelings and dignity, respectively. To deal with this possibility of post-treatment bias, we reanalyzed the regression models of Table 2 without controlling for ideology and free speech. The results did not change qualitatively from the original results (see Table A2 in the online Appendix).
Third, online-survey samples generally tend to have richer and more educated respondents than random samples of the population. Although the distribution of the respondents in our sample is only slightly skewed to higher incomes, there are far more educated respondents in our sample compared with the population data (see Figure A1 in the online Appendix). For example, 58% of our respondents graduated from or are students of 4-year college or above, whereas the population proportion is only about 20%. Existing studies do not help us infer the bias derived from this divergence, as this is the first research explaining the association between the perceived harms of hate speech and support for hate speech regulations. Hence, as a second-best solution to this problem, we attempt to measure the bias using our sample data. As already shown in Table 1, education and income do not affect the perceived harms of hate speech, implying that the divergence between the sample and population distributions of income and education may not lead to a significant divergence between the sample and population distributions of the perceived harms of hate speech. Moreover, as shown in Figure A2 in the online Appendix, varying levels of education and income do not significantly change the relationship between the perceived harms of hate speech and support for hate speech regulations. Of course, if other samples derived from other survey studies were used, we might obtain different results. However, at least the results derived from our sample data suggest that the sample-and-population divergence in terms of education and income does not seriously impair the validity of our core arguments.
Lastly, the ages of our respondents are limited to the range between 20 and 69. Unfortunately, we do not have existing studies and sample data that help us infer the bias derived from this age restriction. Instead of presenting our unfounded conjectures about this bias, we accept this limitation, which is inherent in almost all internet-based surveys, and leave the solution to this problem to future research.
7. Conclusions
The concept of dignity is critically important for providing justifications for hate speech regulations, as Jeremy Waldron advocated most famously among other political theorists and constitutional scholars. In this paper, we have presented a set of findings based on the original survey conducted in Japan, which shows unequivocally that ordinary citizens consider the perceived harm of ‘undermining dignity,’ rather than that of ‘causing offense,’ as more valid grounds for governmental regulations. To our knowledge, this sort of empirical evidence has never been presented. Given that Japan's first anti-hate speech law had only recently enacted, it is fair to claim that our survey was conducted in the environment where the respondents were not as prejudiced or predisposed about the issue as those elsewhere. For this reason, we believe that our findings do speak to the generality, beyond Japan, of the dignitarian rationale and its importance in hate speech debate. Further research of course is warranted to confirm whether the public elsewhere also regards the undermining of dignity as reasonable and legitimate justification for governmental regulations.
More broadly, this paper has been an effort to substantiate one of the well-established normative arguments from a behavioral standpoint. While our focus in this paper has been on the citizens’ attitudes toward hate speech per se, we believe that similar studies can be conducted to explore public support for regulations and policies related to the problems of discrimination and redistribution more generally. The importance of bridging the normative and empirical subfields is increasingly recognized in the discipline of political science. However, there still remain skepticisms, and some critics may, for example, regard our endeavor guilty of David Hume's ‘naturalistic fallacy,’ committing the deduction of an ought, a normative proposition, from an is, a descriptive statement about the state of the world. We believe this criticism does not apply. It is true that we are deducing the prescriptive, or even policy-related, proposition that the concept of dignity must be placed at the center of hate speech regulations. This proposition is derived, not from simply observing the state of the world, but from the judgments made by the respondents themselves, who represent ordinary citizens in an established democracy. The point of conducting our survey was not to verify a normative claim made by some famous theorist, but to probe whether the citizens themselves would make the evaluations parallel to that claim. We certainly do not maintain that the regulations of hate speech should reflect the status quo, or what we observe as the state of the world.
In this paper, we have sought not only to determine whether dignity matters, but also to clarify how it matters, by investigating the possible mediation mechanisms. Waldron, in his original formulation, did not fully address this issue, seemingly presupposing a kind of public-centered logic about people's expectation regarding the societal consequences of hate speech. While not denying this causal path, our findings also reveal the importance of the citizens’ more individual-based moral judgments in shaping their regulatory attitudes. Understandably, for normative theorists, whether dignitarianism, or any argument that justifies speech regulation, is rendered as departure from the liberal orthodoxy may be a critical topic worthy of elaborate discussion. From our behavioral standpoint, we simply note that the concerns over societal good and the senses of justice/injustice do seem to go hand-in-hand in the minds of ordinary citizens as far as their attitudes over hate speech regulations are concerned.
