We need to distinguish between scientific observations and scientific theories. A scientific theory, in particular the sort that ends up defining scientific fields, must be in the form of a tested, falsifiable explanation of observations, preferably one that predicts new observations yet to be made.

Psychology's problems don't result from an absence of scientists -- there are plenty. But until those scientists start crafting falsifiable theories about their observations, psychology will remain a pseudoscience.

The peculiar thing is that psychologists don't realize this. It has something to do with how they're trained. At some point, they're told that, with respect to the mind, looking for causes is a fool's errand, and they assume they can create science without proposing and testing explanations for what they observe.

But they can't -- science doesn't work that way. As a result, psychology has produced any number of dried-gourd cures over the years.
