Dan Ariely

Why do smart people make irrational decisions every day? Why do we repeatedly make the same mistakes when we make our selections? How do our expectations influence our actual opinions and decisions? The answers, as revealed by behavioural economist Professor Dan Ariely of MIT, will surprise you.

Dan Ariely's book, Predictably Irrational, takes research findings in behavioral economics and describes them in non academic terms so that more people will learn about this type of research, discover the excitement of this field, and possibly use some of the insights to enrich their own lives.

TED Talks Behavioral economist Dan Ariely, the author of Predictably Irrational, uses classic visual illusions and his own counterintuitive (and sometimes shocking) research findings to show how we're not as rational as we think when we make decisions.

TED Talks Behavioral economist Dan Ariely studies the bugs in our moral code: the hidden reasons we think it's OK to cheat or steal (sometimes). Clever studies help make his point that we're predictably irrational -- and can be influenced in ways we can't grasp.

Dan Ariely - It's become increasingly obvious that the dismal science of economics is not as firmly grounded in actual behavior as was once supposed. In "Predictably Irrational," Dan Ariely tells us why.
