Stereotypes and Self-Stereotypes: Evidence from Teachers’ Gender Bias

The gender gap in math performance substantially increases when students are quasi-randomly assigned to teachers with stronger stereotypes (as measured by an implicit association test)."

Beating their chests: University students with ADHD demonstrate greater attentional abilities on an inattentional blindness paradigm.
"results are most consistent with the ... hypothesis ... that ADHD individuals have an alternative cognitive style which is less equipped to deal with detection of repeated stimuli while comprising advantages in the tracking of stimuli moving in a fast dynamic manner." Inattentional blindness - which many people know through things like the "invisible gorilla" experiment - is one of the reasons why I tend to roll my eyes a bit when people say you shouldn't disagree with an expert.

Orwell on believing untrue things

The point is that we are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality, usually on a battlefield. - George Orwell
