A big thank you for all the interest in this study guide. It was originally created as a fun introduction that took the Cognitive Bias wiki and tried to make it easier to memorize.
However, the authors of the wiki article have expressed some concern over the accuracy of certain entries. The document was taken down until that could be corrected.
But, people started asking that I release a new version with a warning. In response, a new "Beta version" of the document has been uploaded with a very strong warning label up front and improved citations. I make it clear that all the text is based on an evolving wiki page and that some of the cognitive biases in there might be incorrect wiki entries. My hope is that this will continue to get people interested in pitching in to help fix the Cognitive Bias wiki pages. :) When the wiki is in a good place, I will take the document out of Beta, and will remove the warning label.
