Yourbias.is & Yourlogicalfallacyis.com – The School of Thought

Here are two excellent resources, along with a detailed write-up of mental models.

https://yourbias.is/ is an easily digestible presentation of 24 common biases that skew our judgment.  It also comes available as a set of downloadable PDFs for free.  Definitely worth the 10 or 15 minutes to go through and identify what may be common tools for you, worth discarding, or at least being aware of.  The interface is pretty slick; you can mouse over for a one line explanation of each and then click through for an expanded explanation.

https://yourlogicalfallacyis.com/ is the same thing, except for logical fallacies instead of biases. Also a very valuable read, except these are all things that you would do better without.  This is one of the better presentations out there, mainly due to the organization and interface.  Absolutely worthwhile.
