That reminds me of a bias study where the researchers were investigating the effects of stereotypes.

They told one group of Asian women that “women are worse at math than men” and another group of Asian women that “Asians are better at math than non-Asians”. Both are common stereotypes.

They then measured how well the two groups did on subsequent math exercises.

Interestingly, they found that the latter group (positive stereotype) performed better than those in the former group (negative stereotype).

As I recall, other research found similar results with Black males and golf scores when told “white people are better at golf” as opposed to “black people are better athletes”.

Not only do stereotypes influence our perceptions of “the other”, but they influence the performance of the other.
