Superrationality, and generalizations of it, must treat options differently depending on how they're named. Consider the penny correlation game: Both players decide independently on either head or tails. Then if they decided on the same thing, they each get one util, otherwise they get nothing. You play this game with...
This is definitely a hack, but it seems to solve many problems around Cartesian Boundaries. Much of this is development of earlier ideas about the Predict-O-Matic, see there if something is unclear. Phylactery Decision Theory takes a Base Decision Theory (BDT) as an input and builds something around it, creating...
Surprisingly, our current theories of anthropics don't seem to cover this. You have a revolver with six chambers. One of them has a bullet in it. You are offered $1 for spinning the barrel, pointing at your head, and pulling the trigger. You remember doing this many times, and surviving...
Introducing what I think may be an interesting toy problem for timeless-like considerations. The Fisherian Runaway is a proposed mechanism for the development of apparently-detrimental ornamentation such as peacock tails. It goes something like this: You start out with females being selective about their mates. They develop some form of...
This post is a response to abramdemski's post, Kelly *is* (just) about logarithmic utility. > any argument in favor of the Kelly formula has to go through an implication that your utility is logarithmic in money, at some point. If it seems not to, it's either: > > * mistaken...
Abram Demski has been writing about Normativity. The suggested models so far have mostly looked at actions rather than semantics, despite suggestions that this is possible and language learning as a motivating example. There is a simple mechanism that seems to me to mostly fit that bill. Model There is...
The standard account of causality depends on the idea of intervention: The question of what follows if X not just naturally occurs, but we bring it about artificially independently of its usual causes. This doesn't go well with embedded agency. If the agent is part of the world, then its...
