America\u2019s news media have erupted with identical, rigidly one-sided features (for examples of herd journalism mooing at its worst, see <i>Boston Globe<\/i>, 11\/10\/05; <i>Rocky Mountain News<\/i>, 10\/20\/05; <i>The New York Times,<\/i> 1\/08\/06; Copely News Service, 12\/19\/05; <i>Washington Post<\/i>, 11\/15\/05; Public Broadcasting System, 1\/31\/02; <i>Newsweek<\/i>, 2\/28\/00) touting a handful of irresponsible scientists led by Jay Giedd of the National Institutes of Mental Health, Laurence Steinberg of Temple University, and Deborah Yurgelun-Todd of Harvard University Medical School, who have made names for themselves with sweeping claims that \u201cscience\u201d has \u201cfound\u201d why \u201cteenagers act the way they do.\u201d<\/p>\n<p>Many of researchers publicizing the \u201cadolescent brainlessness\u201d argument have openly advocated stripping not just adolescent, but young adult rights.<\/p>\n<p><a href=\"http:\/\/www.mclean.harvard.edu\/pdf\/news\/mitn\/mh070529.pdf\" target=\"_blank\">Yurgelun-Todd<\/a> argues that both juvenile and adult teens should be banned from holding licenses or exercising any adult responsibilities. <a href=\"http:\/\/magma.nationalgeographic.com\/ngm\/0503\/feature1\" target=\"_blank\">Giedd<\/a> and Steinberg have suggested that persons under age 25 should not be allowed to vote, drive, or exercise other adult rights. Because the \u201cbrainless teen\u201d notion flatter the agendas of numerous interest groups and facilitates self-satisfied media sensationalism, it has been accepted as fact even though responsible scientists caution against such rash assumptions.<\/p>\n<p>News articles employ sweeping generalizations sympathizing with the suffering parents of teens as if (a) addicted and alcoholic parents, (b) mentally troubled parents, (c) family violence, (d) divorce, and (e) the last 30 years, never happened. It is highly suspicious that at a time when middle-agers display skyrocketing crises such as drug abuse and criminal arrest, \u201cscience\u201d suddenly \u201cdiscovers\u201d that any conflict between adults and youths can be dismissed as the fault of faulty teenage brains.<\/p>\n<p>But there are compelling reasons than the intemperate name-calling reporters and authorities hurl at teens, their crude stereotypes of adolescents, and the self-pitying nature of Baby-Boom parents quoted in such news reports (these are examples of mature adult cerebral cortexes at work?) that should cast doubt on the latest \u201cteen brain\u201d furor. The science behind it is based on antiquated politics and selective citations, not objective rigor. Nor do claims that teenage brains are some awful mistake of nature hold up either in practical research or the real world. If biodeterminist notions about adolescents are valid, they should apply to all teens\u2014yet, middle-class and more affluent American adolescents and European youth display very low rates of risky behaviors of the types commentators stereotype as characteristic of teenagers.<\/p>\n<p><b>1.

Incredibly, academic authorities, officials, and the news media pretend none of this middle-aged calamity exists. They also deny that the most trouble teenaged behaviors they cite to illustrate their \u201cteen brain\u201d disparagements overwhelmingly originate in families and communities where adults are addicted, criminal, abusive, mentally disturbed, and disarrayed. Rather, these \u201cexperts\u201d simply blame \u201cteenage risk-taking\u201d exacerbated by permissive parents.<\/p>\n<p>In startling truth, teens get along with their parents better than their parents get along with each other. The massive numbers of teens living in families rife with parental conflict is only partly indicated by the huge divorce rate in the United States, now approaching 50% of marriages.<\/p>\n<p>Beyond the suspicious contexts for the \u201cdiscovery\u201d that teenagers are mentally incompetent lies the suspicious science itself and its contradiction by real-world research and complete failure to predict real-world behaviors. Major institutions and interest groups, including defense lawyers, have hyped \u201cteen brain\u201d research beyond all reason because of its temporary expediency, not its scientific validity.<\/p>\n<p><b>2. Scientists always seem to find biological flaws in the brains of populations that politicians and the public find fearsome or blameworthy for social problems.<\/b> Over the last century, scientists have variously declared African and Native Americans, Chinese and Japanese, Latinos, women, and eastern and southern Europeans cognitively deficient after \u201cscientific\u201d examination of brain dimensions, cerebral cortex volume, and intelligence testing (see Gould, Stephen J., <i><a href=\"http:\/\/www2.wwnorton.com\/catalog\/spring96\/031425.htm\" target=\"_blank\">The Mismeasure of Man<\/a><\/i>, 1982).<\/p>\n<p>Scientists and interest groups made the same claims about teens in the past. Today\u2019s is just the latest in a series of ill-motivated \u201cscientific\u201d campaigns to brand teenagers as mentally incompetent. <a href=\"http:\/\/www.springerlink.com\/index\/B5236237J7306468.pdf\" target=\"_blank\">University of Washington-Madison researchers<\/a> studied social science literature and found that during wartime and \u201cwhen youths\u2019 labor was needed, they were viewed as quite capable and adultlike,\u201d but \u201cwhen youth were not needed in the work force, they were viewed as more immature and slow to develop\u201d by scientists.<\/p>\n<p>The latest announcement that teenagers are incompetent follows a decade of intense efforts by politicians to blame social problems on adolescents and to obtain stronger controls on youth. Notice that scientists never seem to find brain flaws in powerful populations, even though \u201cscience\u201d has cast far more doubt on the capabilities of the aging adult brain than on teens.<\/p>\n<p>But hasn\u2019t brain research advanced dramatically in recent decades? Yes. To the point that definitive pronouncements can be made about how brain physiology \u201cmakes teenagers act\u201d? Not even nearly. <b><i>Brain research is at a very primitive stage.<\/i><\/b> Consider the cautions of leading scientists, which have received little attention. Public Broadcasting System, for example, did not broadcast its <a href=\"http:\/\/www.pbs.org\/wgbh\/pages\/frontline\/shows\/teenbrain\/work\/how.html\" target=\"_blank\">interviews with leading scientists<\/a> in its \u201cInside the Teenage Brain\u201d show (January 31, 2002), but it did post them on PBS\u2019s website as background. These detailed interviews provided a completely different picture than the breathless broadcast.<\/p>\n<p>Asked, \u201chow much do we know about the relationship between the anatomy or biology of the brain and behavior?\u201d Daniel Siegel of UCLA\u2019s School of Medicine, co-investigator at UCLA&#8217;s Center for Culture, Brain, and Development, and director of the Center for Human Development in Los Angeles, answered: \u201c<b><i>We are just beginning to identify how systems in the brain work<\/i><\/b> together in an integrated fashion to create complex mental processes.\u201d Kurt W. Fischer, Professor of Education and Human Development and director of the Mind, Brain, &amp; Education Program at the Harvard Graduate School of Education, was even more emphatic. \u201cWe do not know very much!\u201d he said, adding:<\/p>\n<p>Key to our understanding is how the brain functions as a system\u2014for example, how neural networks grow and function across brain regions. Most of the recent advances in brain science have involved knowledge of the biology of single neurons and synapses, <b><i>not knowledge of patterns of connection and other aspects of the brain as a system<\/i><\/b>. In time the new imaging techniques will help scientists and educators to understand how brain and behavior work together, but <b><i>we have a very long way to go<\/i><\/b>.<\/p>\n<p>When neuroscience connects to scientific knowledge about cognition and development, it can be helpful in a global way, supporting the cognitive developmental knowledge; but <b><i>it cannot provide specific guidance on its own<\/i><\/b>. With the excitement of the remarkable advances in biology and neuroscience in recent decades, <b><i>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<\/i><\/b>. <b><i>There can be no &#8220;brain-based education&#8221; or &#8220;brain-based parenting&#8221; at this early point in the history of neuroscience!<\/i><\/b> (emphasis mine).<\/p>\n<p>Note well: \u201cour limited knowledge of the brain\u201d at \u201cthis early point in the history of neuroscience\u201d means it cannot be used \u201cto inform policy and practice\u201d or to establish \u201cbrain-based parenting.\u201d Richard Lerner, director of Tufts University&#8217;s Institute for Applied Research in Youth Development, agrees brain research is &#8220;in its infancy\u201d and \u201cit\u2019s way too premature to make those specific links\u201d between biology and behavior. These strongly-worded cautions from the leading researchers diametrically refute the reckless demagoguery flooding the news media and policy forums. As does the practical reality everyone can see: If authorities\u2019 hyperventilations flooding the press about how dangerous teens are were valid, every adolescent in the United States would be dead five times over.<\/p>\n<p><b>3. The preponderance of laboratory research does not find significant differences between adult and teenage cognitive ability<\/b>. Major research reviews have found teenagers do not indulge fantasies of<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/sites\/entrez?cmd=Retrieve&amp;db=PubMed&amp;list_uids=8442566&amp;dopt=Abstract\" target=\"_blank\">invulnerability<\/a> (actually, adults take more irrational risks), are not governed by <a href=\"http:\/\/www.asfar.org\/zine\/inaugural\/truth.html\" target=\"_blank\">hormones or irrationality<\/a>, do not rebel against parents, perceive risks and options as rationally as adults do (that is, not always rationally), and are limited more by inexperience than brain deficiencies. The few studies which claim to find vast differences between teens and adults\u2014such as <a href=\"http:\/\/astro.temple.edu\/~lds\" target=\"_blank\">Laurence Steinberg<\/a>\u2019s video-game simulations and <a href=\"http:\/\/www.pbs.org\/wgbh\/pages\/frontline\/shows\/teenbrain\/interviews\/todd.html\" target=\"_blank\">Yurgelun-Todd<\/a>\u2019s interpretation of facial expressions\u2014have been conducted by ideologues and contain serious method problems. For example, Steinberg, who used video game simulations to claim that adolescents in groups take more risks than adults in groups, failed to control for the vastly differing levels of experience a youth generation raised on video games would possess when pitted against an adult generation with little experience.<\/p>\n<p><b>4. Scientists have not compared teenage and adult risk taking on a level playing field<\/b>. An even worse bias plaguing studies comparing statistical differences in teenage and adult risk-outcome levels (which usually focus on traffic deaths and homicide, for which teens have higher rates, and avoid examining suicides, drug overdoses, or other accidents, for which adults look worse) is <b><i>failure to control for socioeconomic status<\/i><\/b>. This is a fundamental flaw that renders such studies invalid on their face. For example, consider the following straight-across comparison of homicide deaths by race (Table 2).<\/p>\n<h4>Table 2.

fact, two to four times higher among black middle-agers than among white 15-24 year-olds. However, a scientist who argued that African Americans\u2019 high murder rates derived from brain biology inferior to that of whites would be rightly denounced as a racist. Rather, responsible scientists would point out that the races are not being examined under equivalent conditions. For example, higher rates of poverty\u2014while not explaining everything\u2014are linked to higher rates of murder, regardless of race. Note the much higher poverty levels among blacks when compared to whites (Table 3).<\/p>\n<h4>Table 3.

The poorest teens suffer traffic death rates three to five times higher, gun death rates five to six times higher, and gun murder rates 16 times higher than teens living in the richest counties.<\/p>\n<p>The vastly higher risks of poorer teens are not due to their physical exposure to more guns or driving. In fact, richer teens drive many more miles (roughly twice as many per year) and are more likely to live in homes where firearms are present than are poorer adolescents. Rather, the risks are due to the very different contexts in which teenagers encounter guns and driving depending on their differing socioeconomic statuses.<\/p>\n<p>This pattern invites the question of whether supposedly high teenage risks moderate or disappear <b><i>when compared with adults of equivalent poverty status<\/i><\/b>. That is: is it bad brains (nature) or bad poverty (environment) that promotes teenage dangers?<\/p>\n<p>It is disturbingly difficult to compare teens and young adults with older adults on a level economic playing field because there are very few counties in which California teens and young adults enjoy poverty rates of less than 15%, and very few in which adults ages 45 and older suffer poverty levels of greater than 15%.

Per billion miles driven (the best measure of risk), the 39.6 fatal crashes teen drivers suffer is 3.54 times the rate of the safest adult age group, 45-54, at 11.2. Thus, driving risks decline with age until around age 65, with teens appearing to be the riskiest drivers by far.<\/p>\n<p>However, <b><i>when teens are compared to adults with equivalent poverty rates <\/i><\/b>(the next-to-left column), <b><i>the teen risk gap diminishes sharply<\/i><\/b>. Teen drivers are only 1.21 (or 21%) more at risk of causing a fatal accident per billion miles driven than drivers age 45-54.<\/p>\n<p>However, one more adjustment needs to be made. The fatality rate is calculated as fatal crashes per licensed driver. However, many fatal crashes\u2014particularly among poorer populations unable to afford licensing expenses\u2014are caused by unlicensed drivers, which inflates the teen fatality rates compared to wealthier older ages. When fatal crashes involving licensed drivers only are compared at equalized poverty levels (right-hand column), the risk gap between teen drivers and drivers ages 45-54 drops to 19%.<\/p>\n<p>In short, the more the playing field is leveled to equalize poverty rates and the effects of unlicensed drivers for all age groups, the more the teen risk diminishes and middle-aged dangers increase. These are the kinds of adjustments routinely made when social scientists compare risks for other groups in society (i.e., races, or populations of different regions). That teenagers from wealthier backgrounds have driving risks as low as adults of similar economic status suggests that teenage risks appear much more tied to an environmental variable imposed on them\u2014poverty\u2014than to innately hazardous brains.<\/p>\n<p><strong>Conclusion<\/strong>: The supposedly immature brain development that renders teenagers naturally risk-prone mysteriously fails to affect teenagers from more affluent backgrounds, or from Europe or Japan (where youth poverty rates and dangers are low), who routinely display risks lower than adults do. Rather, \u201cscience\u2019s discovery\u201d of the problematic \u201cteenage brain\u201d is just the latest in a long, disgraceful history of alliances between officials, interest groups, sensational media, and a small number of scientists who serve their needs. The ability of authorities to scapegoat unpopular, powerless groups in society instead of facing difficult social problems\u2014in this case, rising middle-aged drug and crime epidemics and the effects of poverty on youth risk\u2014endangers Americans by preventing realistic solutions to serious crises.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The \u201cteen brain\u201d craze: New science or old politics?
