In comments, Bryce Huebner articulates a well-founded reason for skepticism:
"[W]hether these strategies are likely to help at all is contingent on people in the discipline recognizing that there are implicit biases at play in our psychology that we can’t just suppress and move on. The fact is that non-conscious processes play an integral role in our psychology. Moreover, they are incredibly difficult to modulate. And, unfortunately, this is something that is hard for many academics to recognize."
