In the grand tradition of sequences, I'm going to jot this down real quick because it's required for the next argument I'm going to make.

Shalmanese's 3rd law is "Any sufficiently advanced wisdom is indistinguishable from bullshit". Shalmanese's first law is "As the length of any discussion involving the metric system approaches infinity, the likelihood approaches 1 of there being a reference to The Simpsons episode about 40 rods to the hogshead" so judge it by the company it keeps.

Imagine you got to travel back in time to meet yourself from 10 years ago and impart as much wisdom as possible on your past-self in 6 hours. You're bound by the Time Enforcement Committee not to reveal that you are the future-self of your past-self and it never occurs to your past-self that this ugly thing in front of them could ever be you. As far as the past-self is concerned, it's just a moderately interesting person they're having a conversation with.

There would be 3 broad sets that your discussions would fall in: Beliefs that you both mutually agree on, Beliefs that you are able to convince your past-self through reason and Beliefs which make the past-self regard your future-self as being actively stupid for holding. It's this third category which I'm going to term Advanced Wisdom.

Since there's been much questioning of late over "What good is advanced rationality in the real world?", I'd like to remind everyone that it isn't all about post-doctoral-level reductionism.

In particular, as a technique that seems like it ought to be useful in the real world, I exhibit the highly advanced, difficult, multi-component Crisis of Faith aka Reacting To The Damn Evidence aka Actually Changing Your Mind.

Scanning through this post and the list of sub-posts at the bottom (EDIT: copied to below the fold) should certainly qualify it as "extreme rationality" or "advanced rationality" or "x-rationality" or "Bayescraft" or whatever you want to distinguish from "traditional rationality as passed down from Richard Feynman".

An actual sit-down-for-an-hour Crisis of Faith might be something you'd only use once or twice in every year or two, but on important occasions.  And the components are often things that you could practice day in and day out, also to positive effect.

I think this is the strongest foot that I could put forward for "real-world" uses of my essays.  (Anyone care to nominate an alternative?)

Below the fold, I copy and paste the list of components from the original post, so that we have them at hand:
