She is particularly interested in which part of the brain is active when those who are prejudiced view photographs of White and Black people. While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest.

In parallel, the development of causal inference tools has been recognized in the 2019 and 2021 Nobel Prizes in Economics. If different researchers get consistent results from testing a hypothesis, the results are said to be: people cannot rely solely on common sense because they tend to think they know more than they actually do which is referred to as.
