I came across this really interesting podcast yesterday. In it Noreena Hetz talks about the various different factors that influence decision making. She argues that very few people understand the way that they make decisions. She notes that people are not only consuming information in a rational way they are also consuming other kinds of information that they are not necessarily overtly aware of.
This is part of her promotion for her new book Eyes Wide Open: How to Make Smart Decisions in a Confusing World.
