This was the subject of a Radiolab segment not too long ago: http://www.radiolab.org/2010/jun/28/even-the-worst-laid-plans/ http://www.radiolab.org/2010/jun/28/even-the-worst-laid-plan... I have to post links to Radiolab whenever something related comes up on HN because I am so sure that many HN readers would love Radiolab, and I am afraid there are still people out there who haven't discovered it.
