NYT: Boomers Worse Than Kids

I almost missed this great piece in the New York Times the other day. It touches on several of my favorite themes -- Chicken-Little decision making, the pseudoscientific overemphasis on brain measures in research, and of course the fact that we're over the hill and the younguns are cooler than us.

Especially if you've got teenagers, check this out.
A SPATE of news reports have breathlessly announced that science can explain why adults have such trouble dealing with teenagers: adolescents possess “immature,” “undeveloped” brains that drive them to risky, obnoxious, parent-vexing behaviors. The latest example is a study out of Temple University that found that the “temporal gap between puberty, which impels adolescents toward thrill seeking, and the slow maturation of the cognitive-control system, which regulates these impulses, makes adolescence a time of heightened vulnerability for risky behavior.”

We know the rest of the script: Commentators brand teenagers as stupid, crazy, reckless, immature, irrational and even alien, then advocate tough curbs on youthful freedoms. Jay Giedd, who heads the brain imaging project at the National Institutes of Health, argues that the voting and drinking ages should be raised to 25. Deborah Yurgelun-Todd, a psychiatrist at Harvard Medical School, asks whether we should allow teenagers to be lifeguards or to enlist in the military. And state legislators around the country have proposed raising driving ages.

But the handful of experts and officials making these claims are themselves guilty of reckless overstatement. More responsible brain researchers — like Daniel Siegel of the University of California at Los Angeles and Kurt Fischer at Harvard’s Mind, Brain and Education Program — caution that scientists are just beginning to identify how systems in the brain work.

“People naturally want to use brain science to inform policy and practice, but our limited knowledge of the brain places extreme limits on that effort,” Dr. Siegel told me. “There can be no ‘brain-based education’ or ‘brain-based parenting’ at this early point in the history of neuroscience.” This Is Your (Father’s) Brain on Drugs

It's funny how research that talks about some brain function, or uses some brain imaging technique, gets everybody's attention, when straightforward psychological research just bores them. We had a story the other day about the differences between liberals and conservatives, and everybody was taking the differences in brain activity to mean that people are born liberal or conservative. No, the brain activity just shows how you're thinking, and liberals and conservatives think differently -- the research didn't say anybody was born that way. You have to be careful there.
Why, then, do many pundits and policy makers rush to denigrate adolescents as brainless? One troubling possibility: youths are being maligned to draw attention from the reality that it’s actually middle-aged adults — the parents — whose behavior has worsened.

Our most reliable measures show Americans ages 35 to 54 are suffering ballooning crises:
  • 18,249 deaths from overdoses of illicit drugs in 2004, up 550 percent per capita since 1975, according to data from the National Center for Health Statistics.
  • 46,925 fatal accidents and suicides in 2004, leaving today’s middle-agers 30 percent more at risk for such deaths than people aged 15 to 19, according to the national center.
  • More than four million arrests in 2005, including one million for violent crimes, 500,000 for drugs and 650,000 for drinking-related offenses, according to the F.B.I. All told, this represented a 200 percent leap per capita in major index felonies since 1975.
  • 630,000 middle-agers in prison in 2005, up 600 percent since 1977, according to the Bureau of Justice Statistics.
  • 21 million binge drinkers (those downing five or more drinks on one occasion in the previous month), double the number among teenagers and college students combined, according to the government’s National Household Survey on Drug Use and Health.
  • 370,000 people treated in hospital emergency rooms for abusing illegal drugs in 2005, with overdose rates for heroin, cocaine, pharmaceuticals and drugs mixed with alcohol far higher than among teenagers.
  • More than half of all new H.I.V./AIDS diagnoses in 2005 were given to middle-aged Americans, up from less than one-third a decade ago, according to the Centers for Disease Control.

What experts label “adolescent risk taking” is really baby boomer risk taking. It’s true that 30 years ago, the riskiest age group for violent death was 15 to 24. But those same boomers continue to suffer high rates of addiction and other ills throughout middle age, while later generations of teenagers are better behaved. Today, the age group most at risk for violent death is 40 to 49, including illegal-drug death rates five times higher than for teenagers.

Wow -- soak that one up for a minute. Turns out the kids are all right, after all, compared to us olde folke.

Kids, cover your ears, I'm talking to the grown-ups now. [I've always thought that the main thing we worry about is that our kids are going to do the things we did when we were that age. True, we lost a few good ones along the way, but most of us survived it.]

Okay, kids, you can uncover your ears. As I was saying, when we were young, we never did any of those crazy things the kids do nowadays.
Strangely, the experts never mention even more damning new “discoveries” about the middle-aged brain, like the 2004 study of scans by Harvard researchers revealing declines in key memory and learning genes that become significant by age 40. In reality, human brains are highly adaptive. Both teenagers and adults display a wide variety of attitudes and behaviors derived from individual conditions and choices, not harsh biological determinism. There’s no “typical teenager” any more than there’s a “typical” 45-year-old.

Commentators slandering teenagers, scientists misrepresenting shaky claims about the brain as hard facts, 47-year-olds displaying far riskier behaviors than 17-year-olds, politicians refusing to face growing middle-aged crises ... if grown-ups really have superior brains, why don’t we act as if we do?

Put that in your bong and smoke it, grandpa.

Data Show HPV Vaccine Targets More Strains

New data show that a vaccine against the virus that causes cervical cancer partially blocks infection by 10 strains of the virus, in addition to the four types the vaccine targets.

That boosts protection -- at least partially -- to 90 percent of strains causing the deadly cancer, according to data presented yesterday at a medical conference by Merck, the maker of Gardasil.

Merck called it the first evidence of any vaccine providing cross-protection against other strains of the human papilloma virus, or HPV.

Stephanie Blank, a gynecologic oncologist at the New York University Cancer Institute, said the finding could encourage more widespread use of Gardasil in developing countries, where some of the additional strains are more widespread and women rarely get Pap smears to detect early, curable cancers.

Gardasil is approved for sale in 85 countries and pending approval in 40 more; it has racked up about $1 billion in sales since its June 2006 U.S. launch. GlaxoSmithKline is awaiting approval of its own vaccine, Cervarix.

There are more than 60 strains of HPV. About 15 are thought to cause cervical cancer.
