Well for one thing, there appear to be non-deterministic systems (possibly real ones, definitely conceived ones) that we would never say have free will. If x is a radioactive atom whether or not it decays in the next minute is undetermined. But the atom does not have free will. And actually, it is hard to make sense of what free will would be if it was just a lack of determinism since the extent to which an event is undetermined is also the extent to which it is random. One cannot control something that is random. But free will means having control over our actions. Ergo: if our actions are free they cannot be undetermined.
(And I know the particle decay picture is resolved differently with MW, but we don't have any other non-deterministic systems to talk about.)
Last time, I wrote about 11 core rationalist skills. Now I would like some help from the LW community: which of these skills am I good at, which ones am I bad at? Just to recap, the skills are:
I'll post a description of each one of these skills as a comment, and if you think I am good at that skill, vote it up. If you think I am bad at it, vote it down. Don't be too shy - even if you are biased or uncertain - because over the course of many votes, these biases and errors will cancel out to some extent. (This is the "guess the number of beans in a jar by asking 50 people to guess and taking the average" method)
EDIT: We can also comment on each rationalist skill to say how well I am doing at that skill. Later today, I will do this myself.
Thanks in advance!
