It brings to mind knowing about biases can hurt people. When I read those 48 I got the impression of lessons being repeated out of context and with out the reasoning that actually formed them. Looking at wikipedia at the Sources and Inspirations it looks like they were gathered second hand. Looking at Greene's wiki biography I do not see the kind of success that would make me believe that he understood the lessons he gathered.

If you can not regenerate the lesson then employing it might hurt you or people around you and caution is warranted when experimenting with it.
