If psychology were a real science, not one whose 'diagnoses' of what is or is not a mental disease is voted on at conventions, that might be helpful.  

Unfortunately, psychology has too little predictability to qualify as a 'true science'.  It is merely a collection of opinions which are subject to lobbyists at each of their conventions.

I remember when I took psychology at Duck U, there were the 'people' psychologists and the 'rat' psychologists.  The rat psychologists could actually predict behaviors; the 'people' psychologists always were whining about all the multiple variables and 'nature' and 'nurture' as why their efforts failed.   Today, we have the 'let's balance all the medications' school of psychology for people in the ascendancy.
