Atheism and outgroup (in)tolerance

Does atheism in the contemporary secularized Western-European societies reflect the ideals of general inclusivity, open-mindedness, and tolerance? Or do, alternatively, atheists have their own prejudice? The seven studies presented in this dissertation investigate these issues. We found evidence that nonbelievers are not universally tolerant, but may indeed show prejudice toward their ideological outgroups (mainly religious believers and conservatives), and this prejudice may be explained by their specific (low other-oriented) personal dispositions and (rational) values. However, nonbelievers’ prejudice at the same time seems to be importantly limited, in that there was only little evidence of a causal relationship between nonbelief and prejudice, and nonbelievers tended to dislike primarily value-threatening behaviors while generally not discriminating against outgroup members as persons.
