I just think it's implausible that there's been no good research showing solid evidence of choice architecture mattering. Could be, I'm not an expert, but I'd like to see where things stand after a couple more years of research and debate.

The job of scientist is to find and present that evidence.

If your assumption is correct, and Kahneman failed to find good evidence that was there, that makes him a incompetent scientist. I don't think he is.

I respect Kahneman too but rigorous behavioral science can be extremely demanding. Read the rat story here: http://people.cs.uchicago.edu/~ravenben/cargocult.html

Feynman taught us to be scornful of cargo cult science, but fewer have internalized how difficult real science can be in comparison.

If this is the case, though, maybe I shouldn't be surprised that maybe no quality research has been done.

He mostly says that about just one chapter. A significant portion of the book is fallacies of basic statistics and logic.
