How much effort does one need to put into evaluating a community compared to building a well? It could be that a 60% failure rate is more efficient than a 0% failure rate with costly evaluations.

(I'm not familiar with Mr. Beast. I will say that the 2 videos I've seen bordered on psychopathy. But I think the general principle of my statement is still worth exploring.)

This is just an anectote, but I have had the opportunity to visit a village where such a well has been built by a charity. The charity was specifically invited to build the well there because months prior a child had drowned in the waterhole that they used before. I suspect if the villagers would have been able to pool enough resources they would have paid for it by themselves. The things needed to build the well are readily available (I passed a shop in a bigger city in the same country recently that sold them) and it's just a matter of finding some skilled people to do the work.
