Big turnout for @erikphoel's "Emergence, Free Will, and Causal Responsibility" at the Consciousness Club!

I presume all the "First Rule of Consciousness Club" have been made before, so tonight I'll spare you, dear twitters.

Neat summary of the supervenience argument.

How do we measure information and causation?

"The best measure of causation is in bits." (Of Effective Information.)

Coarse-graining can increase the effective information of the very same system.

This works because you can treat causal structure as a Shannon channel, and encode to take noise at the micro level into account.
