Yes, like I said, I read the article, and I read the linked notes. The article was not really about people criticising his book without reading it, the article was about not engaging in qualitative criticism of his spreadsheets.

Caplan indirectly mentions a paper criticising him, and his dismissal is that it doesn't acknowledge the math.

It's entirely reasonable to comment on why you're choosing not to dedicate your time to something. Especially when the thing to be analysed relies on fundamentally incommensurable values.

FWIW, from actually reading his notes and the extracts of the spreadsheets he quickly dips into a number of flaky assumptions and uses them to apply "corrective biases" which make it very easy to dismiss without wasting time on arduous numerical analysis.
