So the new paper…

—finds that immigration economics is identical to other fields of empirical inquiry: researcher priors correlate with results

—finds that the magnitude of this correlation is minuscule

—does not mention the most prominent documented bias of this kind, from one of the authors.

That's false. It is not what the paper shows.

First of all, the "bias" is minuscule.

Quoting Borjas's co-author's analysis of the same dataset:

"Researchers' expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes."

Barely.
