Why is that bad?

It's not, if you know you're doing it.

Are you sure that this isn't all about signaling being a truth-seeker?

Pretty sure. If I wanted to signal, I'd be a lot more high-falutin about it. Actually, my comments do sound a bit high-falutin' (I was looking for a better word than "truth seeker", but couldn't find one) but that wasn't exactly what I wanted to express. The untangling-wires metaphor works a little better. Nominull's "I only seek to be right because I hate being wrong." works too. It's less of a "I vow to follow the pure light of Truth though it lead me to the very pits of Hell" and more of an "Aaargh, my brain feels so muddled right now, how do I clear this up?"

Also, this would be a terrible community to signal truth-seeking in, considering how entrenched the "rationality as win" metaphor is. As I mentioned in the hair example, I think a lot more people here are signaling a burning interest in real-world application than really have one.

So, if you're saying we should seek truth just because it's the truth, and not because it brings practical benefit or pleasure or sends good signals, then what is the use of seeking truth?

Um...this line of argument applies to everything, doesn't it? What is the use of seeking money, if it doesn't bring pleasure or send good signals? What is the use of seeking love, if it doesn't bring pleasure or send good signals? What is the use of seeking 'practical benefits', if they don't bring pleasure or send good signals?

Darned if I know. That's the way my utility function works. And it certainly is mediated by pleasure and good signals, but I prefer not to say it's about pleasure and good signals because I'd rather not be turned into orgasmium just yet.
