Dan Ariely

Recommended by 1 person on the record.

The bar next to each date shows how long ago it was said: 7d is days, 4yr is years.

Robert Cialdini loved it
I've always been a big fan of your work but I was especially taken by your most recent book, Payoff . In fact, I read it twice. Once for content, once for style and was impressed by both times.

That little bar

It says how long ago something was said, so you can tell last month from 2014 without doing the arithmetic. Full and green is recent; it drains and cools as the date gets older, and empties completely at about 6 years.

A striped bar means the date itself is an estimate — the source did not carry an exact one. An entry with no date at all gets no bar.
