As someone who has been a recipient of their "tender administrations" (for being "uncharacteristically" smart) ... bull-crap. Psychology (outside of the study of behavior) IS most definitely a pseudo-science. The article says it, itself:
That is text-book definition of a pseudo-science. By definition, science must be repeatable and verifiable. Anything that is not, is not science.... psychology can rarely make “point predictions”.... imprecision is to be expected, because virtually all psychological phenomena hinge on unknown contextual variables.
