That'll make it that much harder for the next set of researchers to persuade the next set of policymakers to listen to them. So List and Susskind have been looking at scaling failures from the past and trying to categorize what went wrong.

And when you say the wrong people, the people that are being studied then are to what?

So I think of some of the experiments that are done on college campuses, right, where there's a professor who's looking to find out something about, let's say, altruism and racism. The experimental setting is a classroom where 20 college students will come in, and they're a pretty homogeneous population, and they're pretty motivated.

There are many factors that contribute to this voltage drop, including the admirably high standards set by the original researchers.

Another problem in this third bucket, it's a big bucket, is when the person who designed the intervention and masterminded the initial trial can no longer be so involved once the program scales up to multiple locations. Imagine if instead of talking about an educational or medical program, we were talking about a successful restaurant and the original chef.
