One of my favorite observations, which I first heard from Alan Kay, was that “point of view is worth 80 IQ points.” Now, Alan is a very clever fellow, and it’s only just occurred to me now, but Alan never specifies a sign for those IQ points. It’s just as likely that a wrong frame of reference acts as an 80 point penalty as that a right frame provides an 80 point bonus.
This places Alan firmly in the Six Sigma camp long before the movement existed (Alan always has been a leading edge kind of guy).
