I am a behavioral scientist interested in how social motivations influence human judgment and empirical beliefs. As social animals who benefit from group belonging and status attainment, humans evolved to reason in ways that enable them to persuade others of their righteousness and of their value and commitment to their social groups. Although humans care about truth and accuracy, human cognition is also biased toward achieving these social goals.

​

In the moral domain, my research has found that belief in free will is at least partially motivated by desires to blame and punish. Asserting the existence of human free will allows people to punish others and to justify that punishment to observers and thus reduce risks of retaliation.

​

In the political domain, I have found that people hold double standards in their evaluations of information and behavior. Both liberals and conservatives are relatively credulous toward information that supports their ideological agenda and skeptical and censorious of information that challenges it. And both are relatively forgiving of the moral failings of in-group members compared to those of outgroup members. Although scholars continue to debate differences in epistemic virtues on the left and right, my research suggests both liberals and conservatives are similarly vulnerable to such in-group biases. In my view, this is to be expected given the evolutionary pressures for social status and evolutionary costs of ostracism.

​

I am also interested in motivated cognition in evaluations of science and among scientists. Scientists are humans after all, and it would be quite surprising if they were not vulnerable to similar biases, errors, and motivations as other people. My ongoing work has found that scientists who believe unpopular conclusions are empirically true are particularly likely to self-censor their empirical beliefs. This suggests that professional discourse (and perceived scientific consensus) surrounding controversial conclusions is systematically biased toward the rejection of socially undesirable empirical conclusions.

​

On the more applied side, I am particularly interested in finding ways of de-biasing science and scientists and expediting the truth discovery process. Over the past two years, I (along with Professor Philip Tetlock) have been participating in and advocating for adversarial collaborations, a methodological procedure in which disagreeing scholars mutually design methodological procedures to test their competing hypotheses. This process can facilitate more rigorous science because both proponents and opponents must agree to fair and unbiased tests. Learn more about our initiative here.
