Hostile Telepath - Problem Overview
The Hostile Telepath Problem comes from this post by Valentine on Lesswrong. In this series, I'll be re-explaining it in my own words, but if you want to read the original, absolutely check out the above link. If only want my thoughts not reexplaining the original, see the Corollary List here.
The Hostile Telepath Problem, at its most basic, works like this:
You need the Telepath to believe you.
You say "I think X".
The Telepath says "You don't /really/ think X. You're lying."
You now need some way to fool their Telepathy.
Now of course, no one is actually Telepathic. We're not talking about magic here. Instead, the Telepath is using some other rule to check if you "really" believe what you say, maybe microexpressions or body language or tone. Or they might be making it up entirely, gaslighting you by claiming to see some invisible "tell" that doesn't exist. Regardless of why the Telepath believes you're lying, you need to convince them, so you're in a Hostile Telepath Problem.
If you think you've got it, most on to the next post. Otherwise, I'll give some examples below the break.
