It seems to me that a psychologist can do science whether or not psychology is science so it’s a bit of a cat fight.
Psychologists do not “do science.”
They play “TV repairman” with your body, giving this drug or that, whatever is in fashion, much like a home owner of the ‘50s hauling all of the tubes of their TV set to the drug store in a bag, to be tested on the machine.
Its “wack a mole” or “skittle ball,” but certainly not science.
