This is amazing. I wanted a good reference for a while now, both for self-improvement but also trying to get better characterization in my writing.
I like to attribute specific cognitive biases to characters that are appropriate to their personality and the narrative, etc., but the list of specific biases that I actually know about off the top of my head is pretty short.
Also kinda funny since, as a borderline wikipedia-addict, I've tried using the page on cognitives biases before as a cheat sheet, but as the article say it's not the most complete or intuitive. This one's great.
