Dr. Syntax, it seems to me that iNow has linked to peer-reviewed articles, which is considered a valid way to oppose an argument. It's not really Appeal to Authority, which would be iNow throwing out one Dr.'s name and saying "Since he doesn't agree with it, it's wrong, and he's right, because he's a doctor and he must know exactly what he's talking about."
Now, what I know about psychology is probably equivalent to that of a small gerbil's, but using my common sense, I do not think Primal Therapy would work.
Why would I want to scream about stuff that makes me mad? It seems that that would just heighten my propensity to just scream whenever something makes me mad, instead of me addressing what is exactly making me mad, and then seeing if I am in the wrong, or if I could help "enlighten" the idiot that is making me mad.
That's how I feel anyways.
