> Psychology is really hard, the system you are studying is many times more complex than many other fields.

If that's true though, then the mathematical rigor that should be demanded from its students must be higher than in other fields in order to achieve the same level of reliability. I doubt that is the case today.

The gp is basically saying psychologists can’t get the math right because most don’t like math and are just playing house to get publications. I am saying many do appreciate good statistics and go to bed worrying about it at night, and the lack of general reproducibility has more to do with the complexity of the field.

In most cases you have to find and convince a statistically representative sample to participate, and that’s so expensive and hard enough to often not be done completely, without having to consider that a statistically representative sample of individuals for many psychological phenomena is an impossible task.
