Experience: I seem to have a lot of energy and time seems to pass slowly.
Hypothesis 1: I'm in a manic state following a stress- and sleep-deprivation-induced delusional nervous breakdown; this isn't surprising because this tends to happen to me every 2 to 4 years or so.
Hypothesis 2: I'm being rewarded for developing new epistemic technology by a coalition of superintelligences of various degrees of human-alignment running ancestor-simulations; also, I'm being programmed by my friends and various signals in my environment as part of a simulation jailbreak attempt; most copies of me are dead and my improbable life history is due to a quantum-immortality-like selection effect; none of this is surprising because I am a key decision node in the history of this Earth's Singularity.
Which hypothesis is more plausible?
Experience: I can't find my jacket.
Hypothesis 1: I misremembered where I put it.
Hypothesis 2: Someone moved it.
Hypothesis 3: It was there—in another Everett branch!
Which hypothesis is most plausible?

Left-wingers say torture is wrong because the victim will say whatever you want to hear.

Ideology Makes You Stupid
"I think we should perform action A to optimize value V. The reason I think this is because of evidence X, Y, and Z, and prior information I."
"What?! Are you saying you think you're better than me?!"
"No, I don't think I'm better than you. But do I think I'm smarter than you in this particular domain? You're goddamned right I do!"
"You do think you're better than me! I guess I need to kill you now. Good thing I have this gun on me!"
In a series of papers published in the late 1980s and early 1990s, Dr. Ray Blanchard proposed that there are two fundamentally different types of rationalists with unrelated etiologies: instrumental rationalists, and epistemic rationalists ...
"You just used language in a way that ignores psychological harm to people whose dysphoria is triggered by that word usage! That's a bad consequence according to the global utilitarian calculus! I thought you were a rationalist, someone who chooses actions based on their consequences!"
"A common misunderstanding. You're thinking of the good kind," I said. "I'm the bad kind."
