Social psychology is not a very politically diverse area of inquiry, something that could negatively affect the objectivity of social psychological theory and research, as Duarte et al. argue in the target article. This commentary offers a number of checks to help researchers uncover possible biases and identify when they are engaging in hypothesis confirmation and advocacy instead of hypothesis testing.

We agree with Duarte et al. that bias in social psychology is a serious problem that researchers should confront. However, we are skeptical that most social psychologists adhere to a liberal progress narrative. We suggest, instead, that most social psychologists are paranoid egalitarian meliorists (PEMs). We explain the term and suggest possible remedies to bias in social psychology.

Meta-ethical pluralism gives us additional insight into how moral communities become cohesive and why this can be problematic (even dangerous) – and in this way provides support for the worries raised by the target article. At the same time, it offers several reasons to be concerned about the proposed initiative, the most important of which is that it could seriously backfire.

In our target article, we made four claims: (1) Social psychology is now politically homogeneous; (2) this homogeneity sometimes harms the science; (3) increasing political diversity would reduce this damage; and (4) some portion of the homogeneity is due to a hostile climate and outright discrimination against non-liberals. In this response, we review these claims in light of the arguments made by a diverse group of commentators. We were surprised to find near-universal agreement with our first two claims, and we note that few challenged our fourth claim. Most of the disagreements came in response to our claim that increasing political diversity would be beneficial. We agree with our critics that increasing political diversity may be harder than we had thought, but we explain why we still believe that it is possible and desirable to do so. We conclude with a revised list of 12 recommendations for improving political diversity in social psychology, as well as in other areas of the academy.
