> because we waste time on money on programs that have no chance of success. And presumably learn from it. While wasting a lot of money and effort (and people) on programs that won't work isn't good, neither is not trying because the effect is presumed, pre hoc, to be small or non-existent. We live in a world where most people aren't enabled to achieve their potential. Figuring out that extrinsic rewards don't work to motivate behavioral changes or achievement for some people of a certain category, regardless of why, will hopefully result in the testing of other non-extrinsic-reward interventions that may work to motivate.
