Emil O W Kirkegaard

I actually don't know as much about Lynn as I should. @KirkegaardEmil is probably a good authority on that.

I think you should focus less on authors and more on the data. Read the books. There is no substitute to hard work.

Have you read the criticism? It specifically mentions the data selection is at least partially dodgy. And author matters in this case.

This is not some random niche scientific paper, this is a highly politicized issue, so any bias is relevant.

Of course I have read the criticism. I have also read the rebuttals and I'm closely familiar with the underlying data.

One cannot find the truth by trying to second guess author motivations. One must look at the data. No substitute to hard work.
