It's not weird when it's your weirdness

I don't play golf. Good thing, too. Here's what came in the mail from the Edwin Watts catalog yesterday:

"The Rossa Titallium Anti-skid Groove System Insert (AGSI) reduces skid, promoting precise line and optimum speed control."

The thing is, when people are defending herbal astrology, anti-resonant stereo speaker pucks or angels, they are very sure they are right. And often willing to spend a lot of time and money to prove it. $78,000 record players probably do sound better... to someone who believes they will. Same with advice from A-list consulting firms or results from a particular search engine.

Is any of it science?
