Having tried to do polyphasic myself twice, and having read a good deal of material from other people, I really would not suggest many tests for 2 reasons:
So, that's my basic suggestion. Pick 1 metric, at most, which requires effort on your part.
Zeos require little-to-no effort, so you can add on 1 metric. My suggestion is spaced repetition (Wozniak would also thank you for data), but also valid would be something like dual n-back (DNB) or the Psychomotor vigilance task (PVT).
This is the public group instrumental rationality diary for the week of August 20th. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes!
