I would need more details in order to comment on specific studies or results. Which passages from Dawes reflect poor scholarship? Which Gigerenzer studies contradict K&H results or conclusions (stated in which papers)? I also look forward to a more specific explanation of what you think Gigerenzer's point is, and why the articles I linked to fail to address it.

(For those who are interested, I believe the highly-upvoted comment Will refers to is this one.)
