Sir;I listened Feb.8, 6:30PM to a discussion of a poll conducted by Dan Ariely(Predictably Irrational).I am puzzled by the small response(600 responses)I*ve been listening even before Mr.Ryssdal,when David Branccacio was the Marketplace host. I like the content of Marketplace where I was able to hear reports from Davos.So,I*m puzzled;I also listen to the Marketplace Morning Report with Steve C. and Brad R.Dan Ariely is interesting as part of that group of behavioral economists Richard Thaler,Cass Sunstein(Nudge),the psychologists,the late Amos Tversky,and Nobel laureate Daniel Kahneman.Maybe,also Brad DeLong.That*s why I*m pretty confident with President Obama,with Lawrence Summers,Peter Orszag,Austan Goolsbee,Cass Sunstein.Thanks,David Beuoy.
