Eekkk!I studied Science and did some Psychology. It was too wishy-washy for me after doing straight science, but maybe it was just my professors. They were pretty lazy.
I like the idea of Pschology, just not sure if it's for me as I can see all the faults in the research methodology and it seems unethical to pursue the research if you know it's faulty. Of course I can't speak for all of Psychology, this is just my experience.
I think it's very powerful if you do it the "right" way.
