Not off-hand; I haven't kept lists or done any explicit tests of him.
Some of his theses are so incredibly broad I'm sure there must be plenty of counter-evidence or null results, like his farmer-forager thesis, but none of them overlap with my own particular areas of interest such that I could confidently 'yes, that is clearcut confirmation bias' (like I can with some advocates of dual n-back or various supplements).
The only example I can think of right now is the topic of perpetuities/compound-interest charity: he had the thesis that they are helpful and also stymied by laws. I provided additional examples of the latter, which he happily posted to OB; I recently provided partial counter-examples to the former, the Islamic world's experience with the perpetual charities called _waqf_s, which he has - as far as I can tell - ignored twice now.
I'm curious about the n-back confirmation bias and the evidence those folk neglected.
I have neither the qualifications nor the access to properly understand these two paywalled critiques of the RAND Health Insurance Experiment.
Health Plan Switching and Attrition Bias in the RAND Health Insurance Experiment
The Rand Health Insurance Study: A Summary Critique
Has there been any talk about either of these on OB/LW? If not, why not and could anyone with access to the papers make any comments about how much weight they carry?
I post this here because the RAND results are brought up so often in discussions here, I hope others find it to be an appropriate venue.
