New research suggests people are more likely to endorse conspiracy theories if they would be willing to personally participate in such a conspiracy. … “At least among some samples and for some conspiracy theories, the perception that ‘they did it’ is fueled by the perception that ‘I would do it. … People who have more lax personal morality may endorse conspiracy theories to a greater extent because they are, on average, more willing to participate in the conspiracies themselves.” (more; HT David Brin)
All the commentary I’ve found on this seems to take it as evidence against conspiracy theories, since it offers a non-evidential explanation for why people might believe in such theories. For example, people are eager to mention birthers in the same breath, to discredit them. But in fact this result tends to support conspiracy theories.
Think about it. Why are conspiracy theories in such disrepute, given that there have in fact been many real conspiracies in the world? One theory is that conspiracy theories just tend to be wrong – that there is some bias which makes people believe them too much, and the anti-conspiracy attitudes you see are a response to that bias. Another theory is that the people who tend to support conspiracy theories are disliked, independently of the evidence supporting their theories. The result above adds support for this disliked theory, relative to the bias theory. And this gives you less reason to believe there is in fact a widespread bias to believe too easily in conspiracy theories. Which is evidential, if not social, support for such theories.
