@chai2,
In the closet of psychology there many skeletons, some more definitive than others while many even more egregious than dispositionism. But these tests taint the entire field. For example there are the personality tests which are poor predictors of job performance. I hope when I'm in the job market searching for something, such a test is not the last variable standing in my way. In my mind, in reference to physical sciences, I see psychology as nothing more than a pseudoscience. But then you will tell me: asp, it's a soft science not a pseudomorphine. And I'll reply potato, patato.
