A recent study shows that when Tiger Woods plays in a golf tournament, the other players perform worse than they do when he doesn't play.
Analyzing data from round-by-round scores from all PGA tournaments between 2002 and 2006 (over 20,000 player-rounds of golf), Brown finds that competitors fare less well -- about an extra stroke per tournament -- when Tiger is playing. How can we be sure this is because of Tiger? A few features of the findings lend them plausibility. The effect is stronger for the better, "exempt" players than for the nonexempt players, who have almost no chance of beating Tiger anyway. (Tiger's presence doesn't mean much to you if the best you can reasonably expect to finish is about 35th-there's not much difference between the prize for 35th and 36th place.) The effect is also stronger during Tiger's hot streaks, when his competitors' prospects are more clearly dimmed. When Tiger is on, his competitors' scores were elevated by nearly two strokes when he entered a tournament. And the converse is also true: During Tiger's well-publicized slump of 2003 and 2004, when he went winless in major events, exempt competitors' scores were unaffected by Tiger's presence.
Research papers with a woman as the primary author are more likely to published if the author's gender is unknown.
Double-blind peer review, in which neither author nor reviewer identity are revealed, is rarely practised in ecology or evolution journals. However, in 2001, double-blind review was introduced by the journal Behavioral Ecology. Following this policy change, there was a significant increase in female first-authored papers, a pattern not observed in a very similar journal that provides reviewers with author information. No negative effects could be identified, suggesting that double-blind review should be considered by other journals.
When watched, squirrels fool would-be nut thieves by pretending to bury nuts.
In the journal Animal Behaviour, biologist Michael Steele at Wilkes University in Pennsylvania examines squirrels' caching of nuts. While the furry-tailed creatures made a show of digging a hole in the ground and covering it with dirt and leaves when watched, one time out of five they were faking and nothing was buried.
The squirrels' deception increased after their nut caches were raided.
This is interesting. The PGA offers a non-traditional pension plan for their players that depends on how they perform throughout their careers. Tiger Woods, who performs quite well, could be eligible for almost $1 billion for his retirement if he keeps playing and winning. Billion. Wow.
Tiger Woods is playing the best golf of his career (and possibly anyone's career) and he's not getting credit for it because he's not winning huge against a vastly improved field. "Woods of the '90s played against great talent hindered by a lack serious training; today, Woods plays against great talent enhanced by serious training. The slack is largely gone, as is the reasonable expectation of double-digit victory." He's also come back after slumps due to swing tinkering, marriage, and the death of his father.
The Stev(ph)ens Dubner and Levitt report on some recent research suggesting that people who are good at things got good at them primarily through practice and not because of innate talent.
Their work, compiled in the "Cambridge Handbook of Expertise and Expert Performance," a 900-page academic book that will be published next month, makes a rather startling assertion: the trait we commonly call talent is highly overrated. Or, put another way, expert performers -- whether in memory or surgery, ballet or computer programming -- are nearly always made, not born. And yes, practice does make perfect. These may be the sort of cliches that parents are fond of whispering to their children. But these particular cliches just happen to be true.
The talent myth described here seems to be distinct from that which Malcolm Gladwell talks about in relation to talented people and companies, but I'm sure parallels could be drawn. But back to the original article...I was particularly taken with the concept of "deliberate practice":
Deliberate practice entails more than simply repeating a task -- playing a C-minor scale 100 times, for instance, or hitting tennis serves until your shoulder pops out of its socket. Rather, it involves setting specific goals, obtaining immediate feedback and concentrating as much on technique as on outcome.
"Deliberate practice" reminds me of a video game a bunch of my friends are currently hooked on called Brain Age. Available for the handheld Nintendo DS, Brain Age is based on a Japanese brain training "game" developed by Dr. Ryuta Kawashima. The game measures the "age" of your brain based on your performance of simple tasks like memorizing a list of words or addition of small numbers. As you practice (deliberately), you get faster and more skilled at solving these mini-games and your brain age approaches that of a smarty-pants, twitchy-fingered teenager.
Speaking of talented teenagers, this week's New Yorker contains an article (not online) on Ivan Lendl's golfing daughters. In it, Lendl agrees that talent is created, not born:
"Can you create athletes, or do they just happen?" [Lendl] asked me not long ago. "I think you can create them, and I think that Tiger Woods's father proved that. People will sometimes ask me, 'How much talent did you have in tennis?' I say, 'Well, how do you measure talent?' Yeah, sure, McEnroe had more feel for the ball. But I knew how to work, and I worked harder than he did. Is that a talent in itself? I think it is."
Translation: there's more than one way to be good at something. There's something very encouraging and American about it, this idea that through hard work, you can become proficient and talented at pretty much anything.
Russia plans to drive a golf ball off of the ISS with a gold-plated, scandium alloy six-iron into a four-year, low-earth orbit....which may actually damage the space station if the ball is not "hit out of the station's orbital plane". I understand this event will be debuting at the 2008 Olympics in Beijing.
In 2005, 34 poker players earned $1 million playing tournaments, compared to 78 golfers earning the same playing their sport.
Fun speculation on why golf is so popular with men: they evolved an attraction to hunting in natural environments that are a lot like golf courses.
