What do lowering your golf score and overcoming chronic pain have in common?

The key is reliable feedback.

On pain management, recent studies using fMRI technology finds that that showing you a visualization of your own brain’s pain center gives the sort of feedback that lets you figure out what works and doesn’t in fighting pain. Here is a discussion of another study on burn victims. Melanie Thernstrom wrote an interesting article about her own experiences trying this in last Sunday’s New York Times magazine.

Perhaps not as important as pain, but onto golf.

I used to play a lot of golf as a kid. Often eight or more hours a day. I’d do a lot of experimentation, but it was hard to get good feedback when I tweaked my swing or my putting stroke.

While time (and having four kids) has led my always limited golf skills to depreciate badly, technology is on my side. New clubs are much more forgiving then what I used as a kid. But much more interesting to me, especially in light of our recent New York Times column, are new technologies for analyzing the golf swing and providing more immediate and reliable feedback.

I bought a golf swing analyzer for my backyard. You hit a ball into a net off a special pad with electronic sensors and it feeds the information into a laptop with the clubhead speed, angle of attack, spin, etc. On a golf course or a range, it is very hard to really see what works and what doesn’t because the outcome of the shot is affected by so many variables: wind, the exact contact between club and ball, the lie, etc. With the analyzer, seconds after you swing you can get (hopefully) reliable feedback.

Within a week of purchasing the golf swing analyzer, I had added about 7 mph to my clubhead speed with woods, an increase of 8%, implying an increase in distance of 20 yards or even more. Being the weakest human alive, my primary goal in golf has been to hit the ball further, and as hard as I tried without the analyzer, I couldn’t figure out how to do it. I made more progress with the swing analyzer in a week than I had in ten years without it.

Not surprisingly, professional golfers have figured this out as well. An interesting article in USA Today shows how the pros are improving their games using these same types of swing analysis.

Forget about piano and ballet lessons. My daughters are spending the summer hooked up to the golf swing analyzer.

    Great post.

    But your daughter will only make the golf team if she was born in the first half of the year.

    I notice that article’s still the most e-mailed piece in the NY Times over the last 30 days. I notice you boasting about this on the front of your website.

    I really think it’s odd that you’re bragging. You’re spreading disinformation, you know you’re doing it, and you don’t correct it. What’s more, you brag about it.

    World Cup soccer players aren’t more likely to have been born in the first half of the year, as you claimed.

    And several people, like Steve Sailer and David Kane, showed in your comments section why hockey specifically has a pronounced early-year births quirk.

    So both the thesis of that piece and the example you gave the illustrate the thesis were shown to be likely false.

    And yet, you write:

    ” NAKED SELF-PROMOTION
    5.17.2006
    What is the most e-mailed article in the New York Times over the past 30 days? Dubner and Levitt’s most recent “Freakonomics” column, about the work of Anders Ericsson and others in the “Expert Performance Movement.” The gist: talent is overrated; practice makes perfect; do what you love.”

    Inexplicable.

    I think it’s really odd that Bill L. Lloyd has nothing better to do do his best to tie in every post Levitt makes to the recent NYT article.

    But what do I know? Bill might come ask me what month I was born in, and maybe my birth weight while he’s at it.

    There’s a blog posting admitting that the world cup wasn’t a good example. This should’ve been caught prior to publication of the article though.

    The article on pain reminds me of a quote by Temple Grandin in Animals in Translation, where she points out that we seem to be one of the few animals that are completely dibilitated by pain. There’s a reference in the NYTimes article about a proceedure that cuts connections in the brain where patients say the pain is still there, but it doesn’t overwhelm them anymore. She thinks that’s how animals deal with pain - Why a dog that’s just been spayed can be up and playing the same day and nearly pull all of it’s stitches out without pause. They seem to be able to disregard pain more easily than we can.

    All process improvements begin and end with Standardization.

    Reducing Variation helps both pain and golf scores.

    Sophistry,

    If there’s an error in a NY Times piece, the correction should be printed in the Times, not on a supplementary weblog not connected to the Times.

    The article is still being e-mailed around more than any other Times article. There should be a simple correction, an asterisk after the sentence stating that the sentence in untrue. This is standard web journalism practice.

    Unfortunately, such a correction would torpedo the piece, so it continues being spread around the world that more World Cup players next month will be born in the first half of the year than the second, even though that isn’t true. Hardly trivial; it was the first two sentences of the piece.

    I find it amazing that anyone would listen to what Levitt has to say about golf six days after what he says about soccer turns out to be flatly untrue, and he doesn’t offer his newspaper a correction.

    I’m sorry, but that’s intellectually dishonest. Why would you defend that, sophistry?

    Looking at age cutoffs and baseball (I’m not sure if this already appeared in an earlier entry):

    Hooking your daughters up to the golf analyzer sounds like child abuse to me. I have little experience with golf (my one time holding a club was at a driving range, when I hit a ball straight out for about 175 yards — I decided then that it could only go downhill from there) but from what I understand, it is a lifelong addiction.

Larry Summers for Treasury Secretary

Larry Summers
There is a lot of speculation about whether President-elect Barack Obama will choose Larry Summers to be his Treasury Secretary. But some people are openly opposing Summers’s appointment, in part because of controversial comments he made about women in science.
It’s a close question, but I’m hoping that Obama appoints Summers. I have three reasons:

Stuff We Weren't Paid to Endorse

1. Go to Hulu.com. 2. Choose Arrested Development. 3. Start with Season 1 and then watch every episode of all three seasons. 4. You can thank me later. (SJD)

I can scarcely tell a scarlet tanager from Scarlett O’Hara, but The Life of the Skies had me transfixed from the first page. Jonathan Rosen -- who happens to be a friend of mine -- writes with astounding insight, wit, and compassion. The story he tells here is the best kind of odyssey, an outward journey that ends up highlighting the beauty and daring that live inside of us. Here's a Times review of the book, and here's an earlier blog post about the book and the power of suggestion. (SJD)

Even if you don’t have a son fighting in Iraq, even if you don’t read poetry, even if you think you are immune to the power of a mother’s lament – pick up The Warrior and read it right away. Fran Richey has written some of the most powerful stories I’ve ever encountered. It is obvious that her life was changed by living these poems; yours may well be changed by reading them. (SJD)
