On welcoming change

The link is to a piece by Steven Levitt at the Freakonomics blog.

He's just learned a new approach to putting (in golf). That kind of change is often resisted, as I explored here. Levitt does acknowledge a minor downside, but no sensation of loss, even after, by his own admission, he has been barking up the wrong tree for the putting proportion of 5,000 hours of golf.

Is it a matter of mind-set? And is sport an activity which promotes an incremental mind-set?
