Help create an instrumental rationality “stack ranking”?

I recently heard about SIAI’s Rationality Minicamp and thought it sounded cool, but for logistical/​expense reasons I won’t be going to one.

There are probably lots of people who are interested in improving their instrumental rationality, know about and like LessWrong, but haven’t read the vast majority of content because there is just so much material, and the practical payoff is uncertain.

It would be cool if it was much easier for people to find the highest ROI material on LessWrong.

My rough idea for how this new instrumental rationality tool might work:

  • It starts off as a simple wiki focused on instrumental rationality. People only add things to the wiki (often just links to existing LessWrong articles) if they have tried them and found them very useful for achieving their goals.

  • People are encouraged to add “exercises” that help you develop the skill represented by the article, of the type that are presumably done at the Rationality Minicamps.

  • Only people who have tried the specific thing in question should add comments about their experiences with it.

  • Long Term Goal: Every LessWrong user can define their own private stack rank of the most important concepts/​techniques/​habits for instrumental rationality. These stack ranks are globally merged by some LessWrong software to create an overall stack rank of the highest ROI ideas/​behaviors/​techniques as judged by the LessWrong community at any given time. People looking to improve their instrumental rationality can then just visit this global stack rank and pick the highest item that they haven’t tried yet to experiment with, and work backwards from there if there are any prerequisites.

Do you think others would find this useful? Anyone have suggested improvements?
