Uh, then I would probably just keep it to myself, at least for the time being.

The reason I would consider otherwise is that "always strive for the truth, even when it seems like a bad idea at the time" might be a good pre-commitment to make. I definitely believe that it is on an individual level, but for society I'm not so sure. I definitely don't think it's a deontological moral rule to always seek truth, I just think that it's a very good practical rule to have. This concept is laid out somewhere in the Sequences, I think.
