A few people purchased the original version of Predictably Irrational since it came out in February 2008.

Now that the expanded edition is out, it seemed to me that the right thing would be to get the extra material to those who have purchased the book already.  After discussing this idea with HarperCollins, my publisher, we decided to try an honor system for distributing the extra material.

So — if you purchased the original version of Predictably Irrational and you want the extra material, please email  piexpanded@gmail.com and we will email you back the added information in 3 PDFs (a new introduction, added material about the original chapters, and reflections about the financial markets).

Irrationally yours
