CFAR can achieve its goal of creating effective, rational do-gooders by taking existing do-gooders and making them more effective and rational.

I wasn't aware that this was the strategy; perhaps I read the original post too quickly.

This is why they offer scholarships to existing do-gooders.

Well are they attempting to turn non-do-gooders into do-gooders?

That they don't turn people in general into do-gooders does not constitute a failure of the whole mission. These activities support the mission without directly fulfilling it.

Perhaps, but that strikes me as a dangerous first step towards a kind of mission creep. Towards a scenario (3) or (4).

CFAR is creating an alumni network to create benefits on top of increased effectiveness and rationality.

Same problem.
