I predict pushback -- LW won't like that idea one little bit :-)

That claim seems totally fine to me. Inaccurate maps can still be useful, sometimes even more useful than more accurate maps as they can be simpler to use and easier to create. I wrote about that here.

Incorrect maps can also sometimes be useful. Examples of this are adaptive biases like the sexual over perception bias in men. From a truth-maximization perspective young men who assume that all women want them are showing severe social-cognitive inaccuracies, judgment biases, and probably narcissistic personality disorder. However, from an evolutionary perspective, the same young men are behaving in a more optimal manner. One which has consistently maximized the reproductive success of their male ancestors. Another similar example is the bias for positive perception of partners.
