Is There a Difference Between Individual and Population Change?

There isn't a lot of hard, am, statistics around behavior change itself. The only real stuff i've found is some interesting studies that look at the difference between t individual change as opposed to population change. Anis some very human to human inter tive discussin discussions, and soro socratic questioning that just elicits am change. I think it's a shame when people are quite dogmatic about particular techniques and styles, when the evidence can't support that level of conviction. But then also, i find that if thi's some evidence, supposedly evident, informed nihilism that sometimes occurs wher people therefore think it’s not worth giving it a whirl.
