Twisted Skepticism

Twisted Skepticism

Scientists are fond of placing great value on what they call skepticism: Not taking things on faith. Science versus religion, is the point. In practice this means wondering about the evidence behind this or that statement, rather than believing it because an authority figure said it. A better term for this attitude would be: Value data.

My observations: 1. The first task I used to measure my mental function at frequent intervals (e.g., every 30 minutes) resembled an typical cognitive psych task. It wasn’t fun and I had to push myself to do it. 2. I made another test to do the same thing based on the lessons I drew from bilboquet. It consisted of tracking circles around the screen. It was mildly fun.

After I saw that flaxseed oil probably affected my circle-game performance, I wondered how to make its effect clearer. One possibility was to change the input device. I was using the trackpoint on my Thinkpad to move the cursor; what about the touchpad? Might be a more natural task. So I played the game several times using the touchpad. I was a lot slower, presumably because in ordinary usage I’ve used the trackpoint. I wondered: Could I get better on the touchpad? I made a little game to practice. Here is the initial screen.

Drug addiction, sure. The first pleasurable drugs were probably discovered hundreds of thousands of years ago, if not much earlier. All cultures use drugs. Drugs physically reach the brain. But video game addiction? Video games are a millisecond old, compared to drugs. How did they get so potent so fast?

Lewis Carroll on Mercury and Autism

Lewis Carroll on Mercury and Autism

From an article in Rolling Stone about mercury and autism: The CDC “wants us to declare, well, that these things are pretty safe,” Dr. Marie McCormick, who chaired the [Institute of Medicine’s] Immunization Safety Review Committee, told her fellow researchers when they first met in January 2001. “We are not ever going to come down that [autism] is a true side effect” of thimerosal exposure. According to transcripts of the meeting, the committee’s chief staffer, Kathleen Stratton, predicted that the IOM would conclude that the evidence was “inadequate to accept or reject a causal relation” between thimerosal and autism. That, she added, was the result “Walt wants” — a reference to Dr. Walter Orenstein, director of the National Immunization Program for the CDC.

I interviewed Gary Taubes by phone a few weeks ago, shortly after he gave a talk about the main ideas of his new book — Good Calories, Bad Calories — at UC Berkeley. The interview lasted about 2 hours. This is part 8.

How to Be Wrong (continued)

How to Be Wrong (continued)

I asked a friend of mine why she was a good boss. “I was nurturing,” she said. A big study of managers reached essentially the same conclusion: Good managers don’t try to make employees fit a pre-established box, the manager’s preconception about how to do the job. A good manager tries to encourage, to bring out, whatever strengths the employee already has. This wasn’t a philosophy or value judgment, it was what the data showed. The “good” managers were defined as the more productive ones — something like that. (My post about this.) The reason for the study, as Veblen might say, was the need for it. Most managers failed to act this way. I posted a few days ago about a similar tendency among scientists: When faced with new data, a tendency to focus on what’s wrong with it and ignore what’s right about it. To pay far more attention to limitations than strengths. Here are two examples:

SETH ROBERTS: I was a member of the Center for Weight and Health. But the other members didn’t know what I was up to, and had no idea it could have anything to do with actual weight loss. GARY TAUBES: That’s one of the things I’ve found most amusing about obesity research, that you have this disconnect from pre-World War Two, when the people doing it were clinicians who were treating obese patients, to post-World War Two, where first, it’s nutritionists, who do rat experiments. Then, by the 1960s, obesity is considered an eating disorder and it’s being treated by psychologists and psychiatrists. So today, if you looking at some of the major obesity centers in the country — at Yale, at University of Cincinnati, they’re all run by psychologists or psychiatrists. Here’s a physiological disorder of the body, and it’s being studied by psychologists and psychiatrists. They’re not interested in anecdotal evidence, unless it agrees with their preconceptions.

How to Be Wrong

How to Be Wrong

There are two mistakes you can make when you read a scientific paper: You can believe it (a) too much or (b) too little. The possibility of believing something too little does not occur to most professional scientists, at least if you judge them by their public statements, which are full of cautions against too much belief and literally never against too little belief.

Never.

If I’m wrong — if you have ever seen a scientist warn against too little belief — please let me know. Yet too little belief is just as costly as too much.

SETH: When I started your book, I already kind of believed all of your main points. Not all of them, but I was sympathetic. I knew where it was going. I thought “Oh, good. More evidence. This is interesting, and that’s an interesting way to tell that story”.

SETH: Well, I think your book is a great book, and I don’t think its effect is limited to how many reviews it gets. What books do you think your book resembles? I think of it as a book showing that authorities can be seriously wrong, but what do you think?
GARY TAUBES: You know, I don’t know, actually. I can’t answer that question without sounding like a crazed egomaniac, so I won’t. What the book does is try to explain why the paradigm of obesity and chronic disease has to change and then to offer the alternative paradigm. Although I don’t use the word “paradigm” in the second half of the book, that’s what it’s trying to do. I want people to stop thinking about obesity as a disorder of overeating, calories in over calories out, and think about it as a disorder of excess fat accumulation.

SETH: I was impressed with the discussion in your book and lecture about obesity coexisting with poverty in all these different cultures and the implications of that. I’d never seen that before.
GARY TAUBES: I have this feeling, and I guess that all writers (or all neurotic writers) have to some extent, that my work is being ignored. It’s my Rodney Dangerfield complex. Now that I’ve written the book, I occasionally get emails from friends saying that they had some discussion with some obesity researcher, and they said, “Are you going to read Taubes’s book?” and their response was “Well, we know what Taubes thinks, so why should I bother reading the book?”
