Trista, I'm an OLD Psych major myself...... that's the fascination of this stuff.... what you're learning is probably a long way from what was 'true' back in the 70's. In fact, I haven't believed the results of any polls since I took quantitative psych.
From what I gather of Psychology, it will never be fully understood until we can figure out how the brain works. Without knowing how we think, we can't effectively study how individuals behave.
That's why I'm an Accounting major
