I'm not sure. I know my point of view could be biased. I was surprised myself about what others told me. But it doesn't matter. I think we can both agree that psychology today isn't at the level it was 100 years ago - it's a sudden improvement that didn't happen for thousands of years. The discussion was about the "why did it take so long", or "why now". @mrkeen argued that it was the scientific method. I'm not convinced. The scientific method was used since 1800s, I think, yet 150 more years passed with not much happening in this field. - Was it the consequences of war in the age of bombs, mines, gas, machine guns? - Was it Freud that made psychology a science? - Was it marketing that gave a boost in research?
