extroverts are more likely to cheat unless they're likely to get caught
That's not what your link says. First, there is no cheating involved, we are talking about degrees of cooperation without any deceit. And second, it's not about "getting caught", it's about being exposed to the light of the public opinion which, of course, extroverts are more sensitive to.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
