Why Dwight from ‘The Office’ Is Wrong About the Body’s Immune System
Salon has a cool new column debunking health myths in pop culture. The first target? Dwight Schrute:
What’s wrong with this picture?
The first problem with Dwight’s take on the hygiene hypothesis is that he is confusing immunity against infection with protection against allergies. The second is that by the time you’re old enough to eat phlegm-drenched toast for breakfast, it’s too late to confer ironclad immunity against infection or allergy, because you need to develop it in early childhood. (Perhaps, in his toilet-side collection of medical journals, Dwight confused the hygiene hypothesis with a recent study showing that infants and toddlers in daycare who get sick a lot tend not to get sick as often once they hit kindergarten and beyond. Details, Dwight. Details!).
The biggest problem, though, with this pop culture view of the hygiene hypothesis is that in two decades of research since Strachan first made his comments, things are turning out to be far more complicated than anyone imagined. In short, research is showing that exposure to some bugs and allergens at an early age can protect us from allergies, while others do the opposite, triggering your body’s immune system to go haywire and exacerbate allergic symptoms. Why one trigger would protect while the other irritates our bodies probably has everything to do with how our immune system reacts and is regulated, though many details are still beyond our scientific grasp.
The Psychological Perils of Solitary Confinement
I had a chance to catch up on a ton of articles while I was on the plane to/from Sundance (see all /Film’s coverage of Sundance here), so some of my postings over the next week or two may be a bit older than usual.
In any case, here’s Atul Gawande’s examination of whether or not solitary confinement is torture. The short answer to that question: probably yes.
Craig Haney, a psychology professor at the University of California at Santa Cruz, received rare permission to study a hundred randomly selected inmates at California’s Pelican Bay supermax, and noted a number of phenomena. First, after months or years of complete isolation, many prisoners “begin to lose the ability to initiate behavior of any kind—to organize their own lives around activity and purpose,” he writes. “Chronic apathy, lethargy, depression, and despair often result. . . . In extreme cases, prisoners may literally stop behaving,” becoming essentially catatonic.
Second, almost ninety per cent of these prisoners had difficulties with “irrational anger,” compared with just three per cent of the general population. Haney attributed this to the extreme restriction, the totality of control, and the extended absence of any opportunity for happiness or joy. Many prisoners in solitary become consumed with revenge fantasies.
There are solutions to this. Take the British approach, for example:
The approach starts with the simple observation that prisoners who are unmanageable in one setting often behave perfectly reasonably in another. This suggested that violence might, to a critical extent, be a function of the conditions of incarceration. The British noticed that problem prisoners were usually people for whom avoiding humiliation and saving face were fundamental and instinctive. When conditions maximized humiliation and confrontation, every interaction escalated into a trial of strength. Violence became a predictable consequence.
So the British decided to give their most dangerous prisoners more control, rather than less. They reduced isolation and offered them opportunities for work, education, and special programming to increase social ties and skills…The results have been impressive. The use of long-term isolation in England is now negligible. In all of England, there are now fewer prisoners in “extreme custody” than there are in the state of Maine. And the other countries of Europe have, with a similar focus on small units and violence prevention, achieved a similar outcome.
Of course, the U.S. would never allow such vast sweeping reforms. Our toxic political system paradoxically requires all politicians to be tough on criminals without actually examining the root causes of criminality and negative behavior in prisons. It’s a can’t-miss recipe to continue upon the horrible path we’re on.
How Do You Reconstruct a 550-Year Old Battle?
At first, I wasn’t too taken by The Economist’s detailing of how the medieval battle of Towton was reconstructed. But by the end of the piece, I was fascinated and impressed by how much work goes into these things. If you’re any sort of a science dork, as I am, trust me, it’s worth a read:
Piecing together what happened on a single day 550 years ago is exceedingly difficult. Even observers would have found it hard to discern a precise order of events in the confusion. Contemporary accounts of the battle may be politically biased or exaggerated. Mr Sutherland says that the idea of medieval soldiers slugging it out for ten hours, as the conventional view of the battle has it, defies credibility; he thinks there was a series of engagements that led to the main battle and that took place over the course of the day….
The battlefield was first swept for ferrous materials such as arrowheads. That search proved frustrating. The trouble was not too little material, but too much—bits of agricultural machinery and other things dating from after the battle. Looking for non-ferrous items—things like badges, belt buckles, buttons, pendants and coins that would have been ripped off during the fighting—proved to be much more fruitful. After identifying clusters of these personal effects, which seemed to mark the main lines of battle, researchers went back to looking for ferrous materials and started finding a concentration of arrowheads.The battlefield was first swept for ferrous materials such as arrowheads.
