Common meaning:

Study of how the mind functions and affects human behaviour.

Hidden meaning of the Equity religion: 

A mentally unsound Western subject based on the false idea that biology is real.

Discussion:

Since the Equityists don’t believe that biology is real, they don’t believe the brain has any impact on reality. Everything we experience is a result of socialization, not anything to do with structures in the brain.

The idea that the physical structure of the brain has no impact on how we think seems crazy. How could any sane person possibly believe in something that is so clearly wrong and preposterous. The answer, once again, is that Equity is a religion and the idea that the structure of the brain has no impact is accepted by believers by faith. No evidence is necessary to convince them.

The Equity faithful even take their beliefs to the next level and say that Psychology that does not support Equity beliefs, and basing its understanding of the human mind on evidence and testing is a mentally unsound Western idea. Again, this makes sense from the Equityist perspective because they consider themselves to be the only people who are mentally sound and everyone else is either ignorant or perniciously fighting truth.

We must fight Equity lies wherever we find them.
