Civil society organizations (CSOs) can facilitate collective action. This makes understanding what shapes whether people are likely to engage with CSOs critically important. This paper argues that whether an organization is perceived as congruent – similar to an individual in values – is a key determinant of whether individuals will engage with it. I use a conjoint survey experiment to test how organizational attributes signaling congruence influence respondents’ willingness to attend a hypothetical organization’s meetings. I find that individuals are more likely to choose organizations that are more likely to be congruent with them, except when it comes to funding. These findings imply that an individual’s level of comfort with a CSO matters for engagement; thus, CSOs need to consider how they match to their publics when reaching out to potential joiners. Furthermore, donors seeking to support CSOs need to pay attention to their impact on perceptions of congruence.
