Update: Study Guide to help you memorize all of the Cognitive biases!

Cognitive Biases - A Visual Study Guide

You Can Download The PDF Here.

Hello Everyone,

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 made it really 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.

  1. great stuff !! the best I have ever seen on this subject. Thanks

  2. This comment has been removed by a blog administrator.

  3. Great material; thank you!

  4. I don't see any credit for the source of the text. You're allowed to reproduce material from Wikipedia (which is what this seems to be) but you have to credit the source. People may get the impression it's your work.

  5. As Doodznchyx said - the original author, Martin Poulter is rather upset at the lack of accreditation....

  6. The wikipedia links are in the text, but I put more links in there to make it more clear. And, each links to the wiki page. Really sad to hear that the authors are upset, just made this as a helpful study guide. I am open to taking it off line.

  7. What is the copyright state of this? Obviously not the text since it's from Wikipedia, but the graphics and lay out?

  8. I just took it offline. Let's work together to make it more accurate, and put it up when it is done. :D Again, really sad to hear this caused bad feelings.

  9. It says here that it's enough to supply an URL link to WP as attribution, and a list of contributors from the history page would just be unnecessary clutter. The document already has a link to WP written, although it should be to the list article where appropriate.

    Not getting personal attribution is something you simply have to accept when writing for WP. I hope this important document stays up!

  10. I hope y'all get this sorted out soon and are able to re-post. I only got to skim the document and was very impressed. I'm very much looking forward to spending some quality time with the final version. And -- I want my kids to read this, too!

  11. (Martin Poulter here)

    Eric, thanks for taking this offline. I'm sorry if I've discouraged you. Your work to make the info visual and interesting has been a great success: it's my and the other authors' work on the text which needs improving.

    You're free to take any text from WP and repurpose it into something different: that's what the CC attribution-sharealike licence guarantees. You just have to say where the text came from and make the licence terms clear. I and the individual authors are not entitled to, and haven't asked for, individual attribution.

    I hope that the cognitive bias list and the logical fallacy list will soon get to the stage where they are worthy of your treatment, and I will work towards that. Sadly there are a *lot* of crappy/misleading psychology articles on WP, so my work has ended up being thinly spread.

    WP has its own rating system: you can usually see an article's rating when you click the "Discussion" tab. If something is a "Featured Article" or a "Featured List", then it's "finished", or as near as a wiki article can be. A "Good Article" has passed a review and doesn't have major flaws.

    I wasn't upset as such: my feelings were a strange mix of pride that some of my words were suddenly being read by tens of thousands of people, and annoyance at the misconceptions about biases that were being spread. Once again, I hope I haven't discouraged you from using your considerable talent.

    Best wishes Eric.

  12. Thanks Martin. :) Really glad you contacted me. I will be much more careful when posting things in the future.

  13. This was really fantastic. Please put it back up! It was really eye opening.

  14. Hi,

    A relation of mine is a professional in the field of psychology and is interested in the project as it is now (unfinished and all) just to see what it looks like/how it relates to her understanding of the biases.

    If you could contact me at bmehne[_at_]gmail[_dot_]com (sorry for the strange typing, but i prefer my spam folders clean), i would be much appreciative.

  15. Hello Ben,

    Due to all the interest and requests to release a "Beta version". I put a new version of the document up with a very strong warning label up front and improved citations. I made it really clear that all the text is based on an evolving wiki page and that "some of the cognitive biases in here might be incorrect wiki entries" Hopefully this will continue to get people interested in pitching in to help fix the wiki pages. :)

  16. Hi Eric,
