to Research Triangle Less Wrong

Hi all,

New to the list. I'm not in the Triangle so I won't make Thursdays, but I read LW and would rather introduce myself than lurk.

I build Android apps. The relevant one is Debias, a cognitive bias trainer built around the Cognitive Bias Codex: 188 biases across the 4 categories, plain-language definitions with examples, and a quiz mode that drills them through real-world scenarios. It also has a Bias Check mode where you log a decision you actually made and work through which biases were in play, with a history you can look back over.

Disclosure: I'm the developer. It's free, with ads and optional in-app purchases.

If anyone wants to tell me where the taxonomy is wrong, this is the crowd that would spot it fastest.
