Making an open call for interesting papers people may have read arguing for effect (one way or another) of gun legislation on [interesting outcomes]. Gwern, do you know anything, maybe?
No. I don't pay any attention to gun control - too politicized, the data too weak, and too irrelevant to my life to make it worthwhile. (Everyone agrees it's a good idea to be careful with your own guns, and there's little you can do about crime.)
What is something you used to believe, preferably something concrete with direct or implied predictions, that you now know was dead wrong. Was your belief rational given what you knew and could know back then, or was it irrational, and why?
Edit: I feel like some of these are getting a bit glib and political. Please try to explain what false assumptions or biases were underlying your beliefs - be introspective - this is LW after all.
