You got me wrong. I never said that groups in general are stupid.
I meant specifically a average group of average people today. And stupid in the sense that they fail to see any big picture(and also the picture in front of their eyes is usually quite blurry). Quite problematic in a globalised world.
Apologies, I meant that I am more open to the other interpretation. My hypothesis being that I am like most people. :) (Obvious flaws in said hypothesis.)
I don't necessarily think either interpretation is correct. I am curious on just how correct either are. That is, I suspect this is purely a probabilities thing. If that makes sense.
Even that, of course, ignores that there is some wisdom in crowds. I'd guess there is a sense of "inertia" in how people behave/think. With more people, more inertia. Slower changes and seemingly slower progress sometimes.
