In response to my previous post noting that the Flynn effect turns out to be a mirage, at least two respondents have suggested that average IQ has actually been falling, and have pointed to the alleged dumbing-down of politics and popular culture in the last fifty years.
I think both those respondents and the psychometricians are correct. That is, it seems to me that during my lifetime I’ve seen evidence that average IQ has risen a little, but that other traits involved in the “smart or stupid” judgment have eroded.
On the one hand, I’ve previously described the emergence of geek culture, which I take among other things as evidence that there are more bright and imaginative individuals around than there were when I was a kid. Enough of us, now, to claim a substantial slice of turf in the cultural marketplace. This good news is reinforced for me be the explosive growth of the hacker community, which today is easily a hundred times the size it was in, say, 1975 — and far larger than I ever dreamed it would be then.
On the other hand, when I compare Americans today to the country of my childhood there are ways the present comes off rather badly. We are more obese, we have shorter attention spans, our divorce rate has skyrocketed. All these and other indicators tell me that we have (on average) lost a significant part of our capacity to exert self-discipline, defer gratification, and honor contracts when the going gets tough.
To sum up, we’re brighter than we used to be, but lazier. We have more capacity, but we use less of it. Physically and mentally we are self-indulgent, flabby, unwilling to wake up from the consumer-culture dream of entitlement. We pursue happiness by means ever more elaborate and frenetic, diminishing returns long since having set in. When reality hands us a wake-up call like 9/11, too many of us react with denial and fantasy.
This is, of course, not a new complaint. Juvenal, Horace, and Petronius Arbiter wrote much the same indictment of their popular culture at the height of the Roman Empire. They were smart enough to understand, nigh on two millennia ago, that this is what happens to elites who have it easy, who aren’t tested and winnowed by war and famine and plague and poverty.
But there are important differences. One is that while decadence used to be an exclusive problem of the upper crust, we are all aristocrats now. More importantly, where the Romans believed that decadence in individuals and societies was inevitable, we know (because we’ve kept records) that as individuals we are taller, stronger, healthier, longer-lived and more intelligent than our ancestors — that, in fact, we have reaped large gains merely within the last century.
We have more capacity, but we use less of it. And, really, is it any surprise? Our schools are abandoning truth for left-wing bullshit about multiculturalism and right-wing bullshit about “intelligent design”. Our politics has become a wasteland of rhetorical assassinations in which nobody but the fringe crazies believe even their own slogans any more. Our cultural environment has become inward-turned, obsessed with petty intramural squabbles, clogged with cant. Juvenal would find it all quite familiar.
