Epistemic rationality is not equivalent to “being a Spockish asshole.”
Yes, of course. Notably, epistemic rationality only requires you to look for and to prefer truth. It does not require you to shove the truth you found into everyone else’s face.
If you think that epistemic and instrumental rationality would disagree at certain points
One can find edge cases, but generally speaking if you treat epistemic rationality narrowly (see above) I would expect such a disagreement to arise very rarely.
On the other hand there are, as usual, complications :-/ For example, you might not go find the truth because doing this requires resources (e.g. time) and you feel these resources would be better spent elsewhere. Or if you think you have difficulties controlling your mind (see the rider and the elephant metaphor) you might find useful some tricks which involve deliberate denial of some information to yourself.
