It's not a "wild accusation" or personal attack, it's a fundemental truth about the nature of modeling. You can do better against it if you start off by recognizing that it is there. Nothing is unbiased.

The embarassment of retraction is also a strong incentive to not challenge the status quo. If everyone is using the same bias and assumptions no one has to worry about retraction. The more small teams you have, the easier it is for different biases to live; the more centralized, the easier it is to succumb to groupthink.
