For example: people respond positively to confidence. When you make a sales pitch for your company/research project/whatever, people like to see you that you really believe in the idea.

CFAR's Valentine manages to have a very high charisma. He also manages to get out of his way to tell people not to believe him too much and explicetly that that he's not certain.

Based on my current fledgling understanding, this seems to look something like taking a larger perspective, like imagining looking back at this moment 30 years hence and noticing what does and does not matter. (I think that's akin to tucking your hips, which is a movement in service of posture but isn't strictly part of the posture.) I imagine this is enormously easier when one has a well-internalized sense of something to protect.

Having this strong sense of something worth to protect seems to be more important than believing that individual ideas are necessarily correct.

You don't develop a strong sense of something worth by doing debaising techniques but at the same time it's a major part of rationality!CFAR and rationality!HPMOR. At the same time there are people in this community plagued by akrasia who don't have that strong sense on an emotional level.
