If all the effects of ITT were limited to establishing cooperative discussions it would still have huge instrumental benefit for systematic truthseeking. You may dislike classifying it as part of epistemic rationality, but the fact that people who use this technique have more fruitful discussions and thus, all other things being equal, more accurate views, would still be true.

This is, however, not the case. For the reasons I’ve already mentioned in another comment. But also because there is an intersection between “niceness” and “rationality”—the virtue of accuracy.
