Kuhn’s motivator is more subtle and a little sinister. Individual Kuhnian scientists are not critics at all; they accept the prevailing paradigm with barely a contrary thought. But in their enthusiasm to squeeze every last drop of predictive power from that paradigm, they crush the life out of it.
I think this is not right. The key point for Kuhn is the puzzle solving. It's not that you crush the life out of the paradigm, it's that you use it as much as you can and then at some point you get stuck.
