I wonder if this extends to sharing your reasoning for a decision with others. It seems like it might be a sort of social cognitive offload, where we feel more sure with our decisions when we expose our reasoning to other, even unqualified, people. I think hearing no rebuttal gives us assurance, much like someone positively encouraging you to do something does, even if the encourager has no idea the difficulty of the task,your qualifications, etc.
This seems especially relevant for bias disclosure, because now we feel better giving in to those biases because we've issued warnings.
Anecdotally, I see this used in social situations where someone is not particularly nice, who then unapologetically informs everyone that they are "not nice" or "mean" as if it excuses the behavior.
Biases are blaming statements. Saying someone is "not nice" is a blaming statement against a person directly...to avoid the disruption caused by the words which elicited the statement to begin with. Blaming someone else's character to diminish the importance of the statement they made is a well known and oft wielded bias.
Biases work because they allow a steady state of cognitive dissonance to occur. It's only when dissonance is disturbed that it begins to chew up resources - both internally and externally. How much effort should be going into picking a good president here in the US and what is limiting our ability to change things for the better? That's a HARD question to answer and requires a lot of work from a lot of different people to get even reasonably close to breaking the dissonance in society for the better.
Seems a far more efficient solution to let things randomly break at a point for a nice, yet messy, reset on societal cognition.
