Here is the 2013 edition of the Best of Rationality Quotes collection. (Here is last year's.)
Best of Rationality Quotes 2013 (400kB page, 350 quotes)
and Best of Rationality Quotes 2009-2013 (1600kB page, 1490 quotes)
The page was built by a short script (source code here) from all the LW Rationality Quotes threads so far. (We had such a thread each month since April 2009.) The script collects all comments with karma score 10 or more, and sorts them by score. Replies are not collected, only top-level comments.
As is now usual, I provide various statistics and top-lists based on the data. (Source code for these is also at the above link, see the README.) I added these as comments to the post:
- Top quote contributors by total karma score collected
- Top quote contributors by karma score collected in 2013
- Top quote contributors of 2013 by statistical significance level (See this comment for a description of this metric.)
- Top original authors by number of quotes
- Top original authors by total karma score collected
- Best short quotes 2009-2013
So, I think my favorite female public rationalist is Byron Katie, who has a number of great rationality quotes, most of which boil down to this one (which is I think her only quote in the LW RQs):
Close to it is one by Karen Pryor:
Above that is Megan McArdle, and the highest quote I saw that was probably by a woman was this one (I didn't look in to whether or not that Ashley is female), and this is the highest one I saw I'm pretty confident was by a woman. (A number of them were attributed to internet callsigns, which are difficult to reliably map to sex.)
If you think that more female authors on the list would be an improvement, then find female rationalists who say things worth quoting, and then quote them.
