If our interest is understanding social phenomena, we will find that psychological theories are _either_ tautological _or_ fail to tell us anything that we do not already know.
That is a generalization based on my own remembered experience of reading such attempts at analysis. The refutation of it can't consist of claims that this or that psychological theory _could_ explain this or that. Rather it must consist of defending an actual political proposition with such evidence PLUS a demonstration that that proposition cannot be arrived at by other routes.
I don't think any such non-trivial proposition exists.
