More Talk About Why We Don’t Wear Hats Anymore

From Babak Givi, an assistant professor at NYU’s Dept. of Otolaryngology-Head & Neck Surgery:

Dear Freakonomicers,

I am writing in regards to your January 9th podcast [“Are We Ready to Legalize Drugs? And Other FREAK-quently Asked Questions”] and the question about hats. Why people used to wear hats? Stephen made a comment about religious roots of hats and Steven talked about fashion.

I am sure there are links with both, but I would like to note that for the most of the human history, hats were protective garments. We are not spending as much time as we used to out in the open environment. If you spend most of the time outside, you will soon realize that similar to the rest of your body, you have to protect your head from the sun, wind, rain, or snow; but most importantly from the sun. Even now, when we spend most of our time inside our manmade structures, skin cancers are the most common type of cancer in humans. Furthermore, the most common area for developing skin cancers is head and neck, which happens to be the most exposed area of human body, as long as you are not a strict nudist. The effects of ultraviolet rays on developing skin cancers is beyond doubt.  Lightly pigmented skins are extremely sensitive to the sun and with enough exposure most people will develop skin cancers. Hats, similar to the rest of clothing items, protect our skin. In addition, less sunlight will delay development and progression of cataracts (point for wide brim hats). I think our ancestors had developed the habit of wearing hats out of necessity not fashion or religion. But of course through the millennia, we start adding religious, fashion, and symbolic meanings to wearing hats.

Interestingly, people who don’t have much sun exposure and suddenly have an intense exposure for a few hours are more at risk for developing skin cancers. Thus, I would recommend that Dr. Levitt consider wearing a hat when he is playing a game of golf on a sunny day. It’s not fashion, it’s not religion, it’s a health precaution.

Thanks, Dr. Givi — good point.

One more point unrelated to this e-mail but having to do with our FAQ episodesBecause they are primarily just “mailbag” episodes — Levitt and I trying to respond to listener questions — they are inherently much less researched and complete than a typical Freakonomics Radio. They are more like a call-in talk show than, say, a news magazine. That said, we inevitably fail to frame certain questions as they should be framed.

A good example is our discussion of the U.S. Postal Service in the same episode that Dr. Givi wrote to us about. We talked about a number of ways the USPS could improve itself — but, as many of you pointed out in e-mails, the USPS is severely limited by its federal commission. So some of the improvements and changes we suggested are simply not allowed as the USPS is currently configured.

It’s a tradeoff, I guess — we put out these casual Q&A’s once in a while, which seem to have a certain value; but they are necessarily not the same type of reporting and analysis as the standard episodes (which, surely, also make omissions and mistakes now and again, though they are more preventable in this context). It’s a tradeoff I am happy to live with — are you?

    I have to disagree with Dr. Givi’s hypothesis. I think the flaw in his reasoning is that most people already have a natural means of protecting their heads from sun exposure: hair. Only those who’ve lost that natural protection, either naturally or through fashion (as I experienced during a stay on Parris Island) really need added protection in most circumstances.

      I trust you enjoyed your vacation on Parris. I understand the food is wonderful there and the staff polite.

      If you read Richard Sennett’s “The Fall of Public Man,” you’ll find an extended discussion of public dressing habits over the past 300-400 years. Sennett’s thesis is that over time we have blurred the distinction between domestic informality and public display in terms of dress and behavior. So men wear fewer hats and women fewer gloves in public– and those items that are worn are more likely to be on the order of toques, ball caps and ski gloves. And let’s not talk about dress on airliners….

      But still your comment may be onto something: many blame JFK for the disappearance of fedoras and derbies (I’m old enough to remember the no-hat vibe from his inauguration); his immediate predecessors– Eisenhower, Truman, FDR, Hoover– did not (how to put this delicately?) have to worry much about hat-hair. JFK did have that problem and was vain enough to care.

        Hi James and Phil:

        I lost my hair twice: Once to Uncle Same, like James; and later, to Mother Nature. The only time I miss it is in early spring, when I get my first scalp burn. It only takes MINUTES to get a burn after the long winter, no matter what precautions I seem to take, so I think the good doctor raises a valid point. As for changing fashions, I like to think bald people have many advantages over the haird, including the JFK hat-hair issue. I remember when I found a comb in a drawer and smiled and threw it away; making fun of guys at the gym blow-drying their hair; and…no haircuts! And, no falloff in attention from the Ladies. From zero when I had hair to…. the same now. So by my math, hair makes no difference in that regard! :)

        May we assume that your tonsure has similarly had no effect on your Presidential prospects?

    Protection against cold has been mentioned, but should be stressed more. One loses a lot of body heat through one’s head. People used to wear hats (nightcaps) to bed in the days when bedrooms were either unheated or had inadequate fires.

    Highly recommend Tilley hats. Guaranteed for life! Nice style. Excellent sun & weather performance. I hated wearing hats until my head became hair-challenged.

    I work in an office so I rarely get to spend much time in the outdoors, but I still wear a hat quite ofte. However, it is usually out of necessity. For instance, in the last week or so before I am due for a haircut… It’s just easier to throw on a hat in the morning than to try and get my hair looking presentable.

    I always enjoy the Q&A episodes. I’ve noticed that they are not as research based, but I like discussions that bring out new perspectives. I big part of my job involves solving problems by looking past the obvious notions that have become standard. I really hadn’t given much thought to the business of the USPS until I heard this episode. However, after listening I went home and began doing some research on the USPS and how they operate. Episodes like this one are what got me interested in Freakonomics. It’s easy to get lost in the traditional approach to the issues we face (or even issues that we don’t realize we face), so it’s always good to hear some alternative ideas… Keep them coming!

    I enjoy the FAQ episodes, and am quite happy with the tradeoff.

    Given the good doctor’s insight, could the answer to the hat question be sunglasses? I, for example, rarely wear a hat, but I use my sunglasses everyday. I think an argument could be made that the rise in popularity of sunglasses (in the middle third of the 20th century) reduced the demand for old-fashioned eye protection. I don’t know what data sets could possibly exist to prove this, but if they were available, I’m sure they’d plot beautifully into a bow-tie graph.

      Btw- I live in a very warm climate, so there’s rarely a concern for heat-loss. Also, I always enjoy the extemporaneous nature of the FAQs.

    I despite of people sometimes. “Here is a free thing. Wait. It isn’t perfect. Well then I must complain in the strongest possible terms” The internet is a wonderful tool. But it is making us increasingly unappreciative and unrealistic.

    I vaguely remember reading somewhere that the hat went away after people started to drive, where there wasn’t as much head room. Not sure if that was true.
