I was just thinking about you...

Richard Dawkins explained in a book, several back and possibly Unweaving the Rainbow, but possibly not, how Uri Geller (could be David Blaine or the other one...) makes people believe he can mend their old watches with the power of his mind.



It's all to do with mass media and maths.

The fact that most people are taken in by mass media, believing everything and anything ("Eoghan" is pronounced "Owen"), helps him achieve the (effect of the) supernatural. But mainly it's that people are generally thick when it comes to maths which nails it.

The argument goes something like this... (I've probably got the figures wrong; it's a while since I read it...)

Imagine five million people watch Uri and he instructs them all to go and find an old watch from a cupboard somewhere in their house. Imagine only two percent of the people watching that programme go and find their old watch. That's still 100,000 people digging around in their "paper bag, cling film and fuses" drawer. *

Watches work by winding them up, or with a battery. Eventually, the winder winds down or the battery fails. Some end up in the drawer. When these 100,000 people find their watches and Uri says "hold it in your hand, rub it, think deep thoughts" etc, the heat from their hands changes the temperature of the winding mechanism or the battery and, momentarily, and because of physics, not because of Uri, the watch works for a few seconds.

Imagine this only happens to one percent of the people who actually find a watch. That's still 1000 people whose watch suddenly works because "Uri says it will"- It's a Kind of Magic!

Uri then says "if your watch worked, phone us!" A mere one percent of the people whose watches ticked for a bit phone up.

Uri still gets to talk to ten people. Plenty to fill the show and, more importantly, all seen by the five million people watching in the first place.

It all rests on these tiny percentages, where coincidences happen, and their effect on the large percentages of people who are open to any suggestion, however stupid, because of their previous experience, ignorance, personality flaws, special needs, religion etc. (Including the very unlikely scenario in which Uri Geller mends your old watch through the TV by pulling a concentrating face and talking with an accent. **)

"Engineered" coincidences for the purposes of entertainment, coercion, gain etc. are one thing, but I guess coincidences don't arise spontaneously all that often. We only think they do because we're more likely to single them out from the background chaff of our lives and remember them.

I only mention this because I seem to have been the on the receiving end of an unexpectedly high number of them recently. Picking just three, some of them were to my disadvantage...
  • the woman in the Post Office to whom I complained and whose cloud of "customer un-service" still surrounded her when I saw her again in a restaurant in the evening. So much so that the waiting staff ended up throwing a glass (nearly) at me...
...some of them were to other people's advantage...
  • Someone I sold a raffle ticket to won the very prize he took the piss out of. (If it needs mending, Chris, see above...)
...and some of them were to my absolute advantage...
  • My nephew was born, unexpectedly, two days ago, in the brief window of time I was around in the North to see him...

Perhaps that was just 2008.

But I'm going to be monitoring in 2009... Happy New Year.
