# Rationality Compendium

I want to create a rationality compendium (a collection of concise but detailed information about a particular subject) and I want to know whether you think this would be a good idea. The rationality compendium would essentially be a series of posts that will eventually serve as a guide for less wrong newbies that they can use to discover which resources to look into further, a refresher of the main concepts for less wrong veterans and a guideline or best practices document that will explain techniques that can be used to apply the core less wrong/rationality concepts. These techniques should preferably have been verified to be useful in some way. Perhaps, there will be some training specific posts in which we can track if people are actually finding the techniques to be useful.

I only want to write this because I am [lazy](http://threevirtues.com/). In this context, I mean lazy as it is described by Larry Wall:

> Laziness: The quality that makes you go to great effort to reduce overall energy expenditure.

I think that a rationality compendium would not only prove that I have correctly understood the available rationality material, but it would also ensure that I am actually making use of this knowledge. That is, applying the rationality materials that I have learnt in ways that allow me to improve my life.

If you think that a rationality compendium is not needed or would not be overly helpful, then please let me know. I also want to point out that I do not think that I am necessarily the best person to do this and that I am only doing it because I don’t see it being done by others.

For the rationality compendium, I plan to write a series of posts which should, as much as possible, be:

*   Using standard terms: less wrong specific terms might be linked to in the related materials section, but common or standard terminology will be used wherever possible.
*   Concise: the posts should just contain quick overviews of the established rationality concepts. They shouldn’t be introducing “new” ideas. The one exception to this is if a new idea allows multiple rationality concepts to be combined and explained together. If existing ideas require refinement, then this should happen in a seperate post which the rationality compendium may provide a link to if the post is deemed to be high quality.
*   Comprehensive: links to all related posts, wikis or other resources should be provided in a related materials section. This is so that readers can deep dive or just go deeper on materials that pique their interest while still ensuring that the posts are concise. The aim of the rationality compendium is to create a resource that is a condensed and distilled version of the available rationality materials. This means that it is not meant to be light reading as a large number of concepts will be presented in one post.
*   Collaborative: the posts should go through many series of edits based on the feedback in the comments. I don't think that I will be able to create perfect first posts, but I am willing to expend some effort to iteratively improve the posts until they reach a suitable standard. I hope that enough people will be interested in a rationality compendium so that I can gain enough feedback to improve the posts. I plan for the posts to stay in discussion for a long time and will possibly rerun posts if it is required. I welcome all kinds of feedback, positive or negative, but request that you provide information that I can use to improve the posts.
*   Be related only to rationality: For example, concepts from AI or quantum mechanics won’t be mentioned unless they are required to explain some rationality concepts.
*   Ordered: the points in the compendium will be grouped according to overarching principles. 

I will provide a link to the posts created in the compendium here:
