Some further discussion has taken place. A new comment from him, in response to the last one I gave (featured in part two of this (originally not intended to be a) series:
Then again I never studied psychology so thank you for elaborating. I just don't know how that general psychology or psychoanalysis as you pointed out helps any in the business world other than bettering someone as a person. I feel the same about art even though I am kind of an artist myself; I think it's totally useless unless you're actually going into art.
And my response to that was as follows:
Well, I'm not sure why you're using the business world as an endpoint (remember though, I still basically agree with your contention), but if that's the one you're going with, I suppose one could argue that, ina ddition to bettering yourself, as you pointed out, you could possibly use an understanding of the human psyche to aid yourself in processes like detecting falsehoods, guaging prospective employees, social networking, closing deals, etc.What do you think? If you offered an opinion after part one and/or part two, does this have any bearing on your opinion at all? As always, feedback is mucho appreciado.
Not that I really buy that (well, to some limited degree, sure) but I think that could be an argument. Although, if you remove the business world as the end goal, you have all sorts of ends: the sake of knowledge, interest, interpersonal relationships (famiial, marital, etc), professional endeavours (counselling), etc etc.
I was never a fan of it, but I don't think it's wise to write it off entirely (not that you or I are necessarily doing that).
If you compare real world benefits of something like your field and psychoanalysis, I think that the clear winner is your field. I think the argument could be made that of all areas of study, mathematics is probably the most important, as much as I hate(d) it.
EDIT: Go back to part one to see a comment from this very same person. His original opinion is no longer one that he holds to the letter. I think we had a productive dialogue here. I also got his major wrong :(
