What are you looking for, exactly? The cognitive biases that CFAR teaches about and tries to help mitigate have been well known in social psychology and cognitive science for decades.

It's also well known in cognitive science that mitigating biases is hard. Having studies that prove that CFAR interventions work is important for the long term.

Keith Stanovich (who's a CFAR advisor) got a million dollar (or $999,376 to be exact) from the John Templeton Foundation to create a rationality quotient test that measures rationality in the same way we have tests for IQ.

If CFAR workshops work to increase the rationality of their participants, that score should go up.

trying to find improvements that result in real practical benefits is part of what CFAR tries to do.

The fact that you try doesn't mean that you succeed and various people in the personal development field also try to find improvements that result in real practical benefits.

But the fact that they're specifically approaching areas of self-improvement that come from well documented to be genuinely real-world phenomena like cognitive biases makes them clearly significantly different to those that are centred around less sound ideas, for example, gods or universal quantum consciousness.

In Willpower psychology professor Roy Baumeister makes the argument that the God idea is useful for raising Willpower. Mormons have been found to look healtier.
