hey ericb, can you tell us how you learned social psychology? maybe what books, sites ... etc ? also im checking the material that FleursDuMal mentioned ;)
Instead of how I learned it, I'll point you to some topics in social psych:
Read Cialdini, the psychology of influence.
This doubles for attracting investment and women: http://en.wikipedia.org/wiki/Social_proof
Social skills-the parens are part of the link: http://en.wikipedia.org/wiki/Mirroring_(psychology)
Halo Effect http://en.wikipedia.org/wiki/Halo_effect
Interesting experiments:
http://en.wikipedia.org/wiki/Milgram_experiment
http://en.wikipedia.org/wiki/Asch_conformity_experiments
If an area I listed here or in the original post is of particular interest, let me know and I'll reply with the specifics of what I meant, or pointers to some info on it.
