Might have gotten better at calibration. I've been bookmarking about 55 items of various prices on a wishlist, and wanted to figure out their total price. I could have made an Excel document with all the prices, but I lazed out of it and assumed their average price was 400 (of my local currency), and computed a total from that. Eventually I did make the spreadsheet. Lo and behold, the calculated average really was 400.48! It's probably my most accurate estimation to date. (Sure enough, n=1, but other instances of calibration haven't been so accurate as to be this memorable.)
Now, to actually get to earn the money for that total price...
This is the public group rationality diary for August 30th - September 12th, 2015. It's a place to record and chat about it if you have done, or are actively doing, things like:
Established a useful new habit
Obtained new evidence that made you change your mind about some belief
Decided to behave in a different way in some set of situations
Optimized some part of a common routine or cached behavior
Consciously changed your emotions or affect with respect to something
Consciously pursued new valuable information about something that could make a big difference in your life
Learned something new about your beliefs, behavior, or life that surprised you
Tried doing any of the above and failed
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.
