Blowing Hot And Cold (Cognition)

In psychology, the concept of "hot and cold cognition" has gained much currency in recent years.  "Cold cognition" is thinking while NOT being swayed by strong emotions, time pressure, and/or peer pressure, while "hot cognition" is thinking when one IS thus potentially swayed in the "heat of the moment".

In what passes for pop neuroscience these days, it has become in vogue to claim that while cold cognition fully matures by around age 16 or so, hot cognition takes much longer, often well into the mid to late 20s.  A major proponent of this theory is Laurence Steinberg, who has written extensively on the topic.  One major study by Steinberg et al. can be found here, which compares various ages in various countries on several hot and cold cognitive tests.  (What the authors call "psychosocial maturity" is a synonym for "hot cognition".) And while such a pattern was apparently seen to some extent in the aggregate, when you break it down by country, the pattern breaks down as well.  And the weak results cannot be explained away by individualism vs collectivism, rich vs poor, Global North vs Global South, eastern vs western, or any other obvious societal characteristics.  And notably, the USA was an outlier where instead of hot cognition improving steadily and largely linearly to (and likely beyond) age 30 like most other countries, it began to level off in the early to mid 20s and plateaued from then onwards.  And one of the other countries actually saw a regress (oops!) in hot cognition in the mid to late 20s.  Cold cognition, on the other hand, was generally much more consistent by country, and nearly always leveled off around 16.

It's almost like hot cognition is actually a skill where "practice makes good enough", as opposed to "biology is destiny".  There is far too wide a variation between individuals and societies to seriously argue otherwise.  And even a quick and cursory observation will reveal that most older adults aren't really all that great at it in the real world.  All the more reason to call BS on any claim that young people's civil rights be curtailed in the name of specious junk neuroscience.

As for the tempting idea that the juvenile injustice system (or a third category) thus be expanded to include young adults (ages 18-25 or so), or otherwise going easier on young adults, please allow me to channel the late criminologist James Q. Wilson.  He noted that even if disadvantaged demographics have a "steeper hill to climb" in terms of staying out of trouble, the prospect of punishment actually has greater utility for them to make it easier for them to climb that proverbial hill.  To that I would add, of course, as long as they are not completely incompetent, and it is in the interest of justice to do so.  And treating young adults as non-adults for that purpose is ultimately a trap, a velvet glove to the iron fist of revoking their hard-won civil rights as well.

That said, it is certainly the very height of hypocrisy to try and punish young people of any age as adults when they commit "status offenses" based entirely on age like underage drinking or smoking, curfew violations, and stuff like that which would not be crimes when adults do these things.  All such "status offenses" thus need to be either decriminalized or removed from the law books entirely, just like victimless crimes (or what the late, great Peter McWilliams called "consensual crimes") more generally.  Ageists really cannot have it both ways!

And finally, people of ALL ages really need to use their cold cognition to plan ahead better, to avoid the pitfalls of relying solely on hot cognition in potentially dangerous situations.  We ignore that at our peril.

What To Do About Lockdown-Induced Arrested Or Delayed Development?

Four years after the official start of the pandemic, two years after practically all restrictions were lifted, and roughly one year after it was declared to be over, the consequences of the lockdowns, quarantines, school closures, mask mandates, and other restrictions can still be seen in its aftermath long after these restrictions were lifted.  This is especially true among children and young people, whose development has been delayed, stunted, or arrested as a result.

It is a truly massive elephant in the room!

Now, the temptation would be to knee-jerkedly raise age limits for various things in response to this, up to and including even the age of majority itself.  You know some people want to.  But that would only exacerbate such developmental delays in practice by kicking the can even further down the road.  The specious idea that "kids today are infantilized, so let's infantilize them even further, because reasons" is absolutely insane.  If anything, we should be doing the opposite and lowering or even abolishing various age limits (within reason), and giving young people a megadose of independence.  That is, go "straight from zero to the Fourth of July", like the song by the band The Killers says, in both the real AND virtual worlds, and certainly no later than age 16.  And at the very, very least, seriously, let's NOT add any more restrictions whatsoever on the already most heavily monitored and (in many ways) restricted generation of children and teens in all of recorded history.

Infancy cannot be re-run.  Childhood cannot be re-run.  And, try as so many adults may, adolescence cannot be re-run either.  The best thing to do is to build a time machine and go back to March 2020 and make it so the lockdowns, school closures, etc. never happened, and that we adopted the "flu strategy" per the original pandemic plan from the get-go per the wisdom of the ages.  Failing that, the second best thing is to rectify things as best we can, yesterday.

The latest attempts to abruptly restrict or revoke teens' access to the virtual world will leave a "social media-shaped hole" in the lives of millions that will most likely NOT be filled with anything good. And after decades of gradually restricting and reducing their access to the real world, it would be a bait-and-switch to disingenuously claim that children and teens will now all of sudden be given more access to the real world in order to fill the void.  Most likely, they will lose access to both the real AND virtual worlds, and increased access to the real world will NOT be forthcoming for a while.

True, the virtual world is no substitute for the real world, as we have all learned the hard way during lockdown.  But as renowned sociologist and youth rights activist Mike Males says, "The dangers of both the virtual and real worlds have been wildly exaggerated. Teens don’t need more restrictions."  Truer words have never been spoken.

And will today's youngest generations, and future generations, ever forgive us?

UPDATE:  What would be a good shorthand to describe what needs to be done?  Twenty-One Debunked thinks we should call it the "Reverse Icelandic Model", that is, the reverse of the vaunted Icelandic Prevention Model (IPM).  When the pandemic and related restrictions and isolation intersected with the existing IPM that had been in place for two decades, it really did a number on the mental health of young people in Iceland.

Does The Latest Brain Study Vindicate The 21 Drinking Age? Well, Not Exactly.

There is a new brain study making the headlines these days.  This study examined postmortem brains of three groups of people:  1) 11 people with alcohol use disorders (AUD) who began drinking consistently before age 21, 2) 11 people with AUD who began drinking consistently after age 21, and 3) 22 people who did not have any AUD at all, though many of them drank at least somewhat.  And among the three groups, only for the early-onset AUD group were epigenetic changes related to the expression of brain-derived neurotrophic factor (BDNF) found, particularly in the amygdala, which is responsible for regulating emotions.  These changes are thought to lead to difficulty regulating emotions, problems with anxiety, and even be part of the pathophysiology of alcoholism itself.

So what does this really mean, exactly?  First of all, the researchers seem to have arbitrarily picked 21 as the dividing line between early-onset and late-onset AUD drinkers, and made no further distinction within the early-onset group (i.e., before 15, before 18, first drink, first drunkenness, first regular drinking, etc.).  Secondly, the study looked at a small sample size of people with alcohol-use disorders (think alcohol abuse/dependence, alcoholism, truly heavy, heavy drinking for many years or decades), who at the time of death averaged well over 10 standard drinks per day and over 100 drinks per week, over 30+ years.  Males were also overrepresented (in fact there were zero women in the early-onset AUD group), and the early-onset group drank significantly heavier then the late-onset group.  It is probably safe to say that these drinkers are NOT representative of the vast majority of those who drink before 21, and given how early the onset of early-onset AUD drinkers tends to be, it would also be safe to say that this early-onset AUD group largely began drinking well before 18, if not before 15.  And even among the late-onset AUD group, the relative lack of epigenetic changes certainly did NOT stop them from becoming alcoholics in any case.

Furthermore, there is no temporality to this non-longitudinal study, so we don't know whether or not these epigenetic changes were due to pre-existing vulnerability or perhaps the early use of other substances such as that now-infamous neurotoxin, nicotine. (Most of the study subjects were smokers, apparently, and about 90% of adult regular smokers typically begin smoking before age 18).

Thus, this study tells us NOTHING about the difference between people in general who begin drinking at 18 versus 21.  NOTHING.  Nor does it vindicate the ageist abomination that is the 21 drinking age.  And anyone who claims otherwise is being, shall we say, "economical with the truth".

Latest Teen Brain and Cannabis Study More Smoke than Fire

The scary-sounding headline from a few weeks ago in USA Today reads, "Marijuana caused more damage to teens' brains than alcohol, study finds".  Yes, there was a study that claimed to find such results, but there is less here than meets the eye.

In other words, there's more smoke than fire.

The actual study itself is predictably behind a paywall, and we will not dignify such questionable research by paying for it, so we couldn't find the actual numbers and thus could not quantify any effect sizes or how long the reported effects lasted, but the abstract and several news articles summarize qualitatively the main findings.  The study, which involved nearly 4000 students from 7th through 10th grades in the greater Montreal area, longitudinally following them for those four years, asking questions about both alcohol and cannanis use and giving tests on memory and response inhibition.  Statistically significant correlations were noted between increased cannabis use and reduced performance on such tests, while interestingly for alcohol such correlations failed to reach statistical significance.

Again, no information about the size of such reported effects, and guess what?  SIZE MATTERS.  And so does duration.  Also, it say nothing about any such correlations beyond 10th grade, nor clearly distinguish between lighter and heavier use.  (The article did note that there were many more daily users of cannabis than alcohol, despite the fact that there were many more drinkers than tokers overall the sample.)  And it is very curious that the typically pro-21 mainstream scientific community are so willing to practically exonerate alcohol in such a study of teens--or perhaps they are simply alcohol supremacists.  And while the sample size and longitudinal nature of this study puts it head and shoulders about most other studies on the matter, given the aforementioned concerns it should still be viewed with caution in terms of causation.

Additionally, the study seems to be silent on the real "dark horse of drugs"--tobacco/nicotine.  Nicotine is a known neurotoxin, particularly during early adolescence, and is far more correlated with cannabis than alcohol use.  Thus, at least some of the reported effects in the study could in fact be due to tobacco, and/or perhaps other substances as well.

Keep in mind that the infamous 2012 study that reportedly found persistently reduced IQs among adults who used cannabis before age 18, was debunked by 2014 study that found no correlation between adolescent cannabis use and IQ or exam performance (though heavy use beginning before age 15 was associated with slightly poorer exam results at age 16).  This latter study did control for tobacco, alcohol, and a host of other factors.  So it is very likely that soon another study will come a long and refute the first study discussed in this article, or perhaps find that any such effects are limited to the heaviest users, particularly those who began before age 15 or 16.  In fact, a 2018 systematic review of 69 studies of adolescent and young adult cannabis use and cognitive functioning found that reported adverse effects were much smaller in size than the prohibitionists like to claim, and generally tend to be temporary rather than permanent, even for frequent and/or heavy use.  And interestingly, no correlation with age of onset, though the mean age of study participants in these 69 studies was significantly higher than in the aforementioned Montreal study.

Other studies as well cast serious doubt on the scary claims of cannabis neurotoxicity as well, and most studies find weed safer than alcohol.

So what is the best takeaway from such studies?  It would seem that while occasional or moderate cannabis use is basically a non-problem, heavy and/or daily/near-daily use (unless medically necessary) should probably be avoided at any age, but particularly for people under 18 and especially under 15.  And while delaying the onset of use, or at least regular use, for as long as possible is probably wise for people under 18 and especially under 15, there is no hard scientific evidence that cannabis is any more harmful at 18 than it is as 21, 25, or even 30 for that matter.  Thus, there is no good reason to keep it illegal or set the age limit any higher than 18.  And even for people well under 18, the criminal law is still far too harsh a tool to apply to something like this that more likely than not turns out to be a non-problem.

Be VERY careful what you wish for, fellas!

In recent years, advances in neuroscience (of which we are still just barely scratching the surface) have led to an increasingly popular tendency to view teenagers and young adults (i.e. anyone under age 25) as having "underdeveloped brains" that somehow justify having their civil rights revoked or curtailed.  Of course, as we have noted before, that same neuroscience has shown that the human brain continues developing well into the 30s and even 40s (and possibly even beyond that), and that the development that occurs between 18-25 (and even a bit earlier) is basically on the same spectrum as the development that occurs after 25.  And that inconvenient fact is clearly ignored by The Powers That Be, for obvious reasons.  But for argument's sake, let's pretend for a moment that no significant brain development occurs after age 25 or so, shall we?

In case you haven't realized yet, this entire argument that young people under 25 should have less rights than people over 25 is really just a warmed-over version of a centuries-old and widely discredited ideology known as "biological determinism".  Similar arguments have been made in the past for black people, women, various immigrant groups, Jews, and other oppressed non-dominant groups in society.  Based on real or imaginary differences between groups, the dominant groups of the time would use such differences to justify their privilege over and oppression of the non-dominant groups. And essentially every single one of these arguments have been roundly debunked, and are really only taken seriously anymore by a few dodgy ideologues on the fringes (*cough* Charles Murray *cough*) and their brainwashed followers (*cough* Faux Noise *cough*).  That's not to say that the demographic groups in question are no longer oppressed or discriminated against (spoiler alert: they are), but today people are far less likely to openly claim "scientific" justifications for such discrimination/oppression than in the past.  Except when it comes to young people, for whom such junk science has apparently become de rigeur as of late. And the dominant group in this case, adults over 25, are certainly all-too-smug about it.  Nevermind that it too has actually been debunked by people like sociologist Mike Males among others. 

It should be obvious now that ageism/adultism is simply one more crucial component of the pyramid scheme known as the kyriarchy, which needs to end yesterday.  But what if there really was a demographic group that actually did show differences, in both physiology and behavior, that could (using the same dubious arguments) be used to justify that group's rights being curtailed?  Well, that group does exist, fellas, and I'm talking about you and me.  In other words, I'm talking about MEN in general, regardless of age.  Based on what we know from Ashley Montagu's 1953 bombshell of a book, The Natural Superiority of Women (last edition published in 1998) as well as its (sort-of) sequel Women After All by Melvin Konner, there are indeed enough brain differences to imply that, on average, males are basically the inferior gender.  Not only do our brains mature at a slower rate than for females, but we ultimately never really catch up completely.  In fact, the gender gap seems to actually widen with age.

Of course, it doesn't matter if we fellas think with our adenoids.  What really matters is how we ACT.  But here too, the evidence is rather abysmal:

• Contrary to stereotypes, we apparently really suck at driving, or at least we are more likely to take stupid risks behind the wheel.  And auto crash and fatality statistics bear this out rather well--and not just for young people, either. 
• Despite having a somewhat higher tolerance to alcohol than women on average (even after controlling for body weight), men are more likely to abuse alcohol and get into trouble with it.  Men are four times more likely than women to become alcoholics and four times more likely to drive drunk. 
• Violent crime of all kinds is overwhelmingly committed by men, especially violence against women. 
• But most crime is male-on-male, making us both dangerous AND endangered at the same time.
• At least 99% of all school-shooters and other mass-shooters have had one thing in common, aside from guns of course.  Care to guess what that is?
• Practically every war ever fought in history was started and waged by men.
• For the past 7000 years or so, most positions of power were overwhelmingly held by men.  And what happened?  We paved paradise and put up a parking lot, we created a desert and called it "peace".  We have devoured and suffocated our own empire, and we will all pay a heavy price for it soon enough.

And these differences between men and women greatly dwarf the differences between young people and older adults, at least when other variables such as socioeconomic status are accounted for.  That's the pink elephant in the room that the (mostly male) purveyors of the new anti-youth biological determinism don't want to talk about.  Why?  Because men are a privileged and dominant group in our society.  That's why.  DUH!

So be careful what you wish for, fellas.  Check your privilege, and your karma as well.  Yeah, you may laugh and be smug about it now.  Snicker, snicker.  But if the futurists are correct, and I think that they most likely are, women will eventually reclaim their rightful place as the new leaders of the free world.  And when that does happen, they will remember exactly how they were treated, so it really behooves us fellas to clean up our act yesterday--both in how we treat women as well as how we treat the younger generations.  The choice is ours, so let's make the right one.
