Chapter 1. "Let's do it..."

On page 4, I wrote:

"As Ayton (2000, p.667) put it (in the style of Irving Berlin): 'Birds do it, bees do it, even educated Ph.D.s do it; why not violate normative rules of rationality?'"

In fact, the song alluded to here "Let's do it (Let's fall in love)" was written by Cole Porter, not Irving Berlin! This fact, which I had known for a long time, suddenly popped into my head - apparently at random - about a year after writing the Introduction. I don't know why I got it wrong in the book.
