Just my hypothesis, but I wonder if larger sample sizes provide a more diverse population.
A study with 1000 individuals is likely a poor representation of a species of 8.2 billion. I understand that studies try to their best to use a diverse population, but I often question how successful many studies are at this endeavor.

In terms of psychological treatments, I am honestly in support of this. Many mental illnesses can have a cultural component to them.

No, I don't think we do. Am I understanding you correctly?
use a diverse population
If that's the case, we should question whether different homogeneous population groups respond differently to the substance under test. After all, we don't want to know the "average temperature of patients in a hospital", do we?
