Gilligan and his Island friends return home

Today my wife surprised the family by renting a DVD of Gilligan's Island episodes from Netflix. I hadn't seen any of these shows for decades--they originally ran from 1964-1967 on CBS. Not that I forgot that the show was goofy. How long did it take to write one of those episodes, 30 minutes? Yet watching two of the episodes tonight did remind me that Gilligan's Island strongly imprinted its images upon the young version of me, perhaps more strongly than anything I remember from back then (I was 8 years old when it originally ran). The characters looked exactly how I remembered them, and the plots were embarrassingly predictable, just how I remembered them as a child. I'd like to say that viewing these episodes served as some sort of time travel, but I simply can't. And the series continues to live on in syndication and DVD rentals, with new generations being exposed to it. Gilligan's Island is a world-class meme, a meme that allowed millions of people to put up their feet to have a bit of mindless fun once each week. And today I was reassured that Mary Ann was as gorgeous as I remembered her. Yes, I far preferred Mary Ann over Ginger. I always did, even as a pre-pubescent viewer. And I was not alone in my preference. On several occasions over the years, I have found myself in discussions where someone raises the concern that too many of today's children waste valuable time that they should be spending exposing themselves to more intellectually rigorous activities. Inevitably, some high-accomplished person in the room then reminds the rest of us about the huge number of hours that most of us spent watching Gilligan's Island when we were children, the original runs and the re-runs. Yet many of us turned out OK. Or at least that is the argument.

Knowledge and Focus

At Edge.com, Researcher David Dalrymple discusses the effect of the Internet on knowledge and focus:

Before the Internet, most professional occupations required a large body of knowledge, accumulated over years or even decades of experience. But now, anyone with good critical thinking skills and the ability to focus on the important information can retrieve it on demand from the Internet, rather than her own memory. On the other hand, those with wandering minds, who might once have been able to focus by isolating themselves with their work, now often cannot work without the Internet, which simultaneously furnishes a panoply of unrelated information — whether about their friends' doings, celebrity news, limericks, or millions of other sources of distraction. The bottom line is that how well an employee can focus might now be more important than how knowledgeable he is. Knowledge was once an internal property of a person, and focus on the task at hand could be imposed externally, but with the Internet, knowledge can be supplied externally, but focus must be forced internally.

The value of uncertainty

At Edge.com, John Brockman recently had a fascinating conversion with Emanuel Derman, who noted that "many physicists and other scientists . . . have flooded Wall Street in recent years." Derman described their work as follows:

They are known as "quants" because they do quantitative finance. Seduced by a vision of mathematical elegance underlying some of the messiest of human activities, they apply skills they once hoped to use to untangle string theory or the nervous system to making money.

Derman then quoted particle physicist Heinz Pagels on the importance of maintaining uncertainty on Wall Street:

Mathematicians and others are endeavoring to apply insights gleaned from the sciences of complexity to the seemingly intractable problem of understanding the world economy. I have a guess, however, that if this problem can be solved (and that is unlikely in the near future), then it will not be possible to use this knowledge to make money on financial markets. One can make money only if there is real risk based on actual uncertainty, and without uncertainty there is no risk.

This quote fuels my suspicions regarding the unnecessarily complex nature of modern financial instruments.

Connectionist beings and toilet mugs

Many of us would love to believe that we are completely rational beings in the sense that we are able to navigate a world strictly categorized in terms of necessary and sufficient conditions. Many of us would also love to believe that with sufficient will power all of us can move beyond unwanted emotions and beyond images and thoughts that "don't belong." That description does not comport with reality, of course. Several psychologists once conducted a hilarious experiment: Students were shown a brand new bed pan. Apple juice was poured into the brand new bedpan out of a commercial bottle of apple juice. The students were then asked whether they would drink the apple juice out of the bedpan. Only 28% were willing. My source for this experiment is page 216 of Heuristics and Biases, by Thomas Gilovich et al. You see, we seem to think as connectionist beings and emotional beings, as well as rational beings. Even though we logically and rationally know that we aren't drinking urine, the visual stimuli too strongly suggest otherwise, at least to many of us. Image by Erich Vieth I have written the above as prelude for describing a gift I recently bought for a good friend. A few months ago, I had described a toilet-shaped mug offered for sale by a well-stocked internet novelty company called PrankPlace. My friend indicated that he would not be deterred from drinking out of such a mug. I decided to put his confidence to a test. Today, I handed him his new toilet-mug and he was delighted. He promptly filled his new mug with coffee, and drank from it. Though he successful drank his coffee, he admitted that it was a bit off-putting to drink from the toilet-shaped mug, even though he absolutely knew that drinking from it would be nothing like drinking from a toilet. I think there are serious lessons here. For instance, when one claims that he is not "racist," there might yet be images and emotions haunting him, things that he acquired as a child, that no amount of logical and rational thought could purge. And maybe we viscerally dislike someone because she reminds us of a teacher that we disliked (even though we are certain that she is not that teacher). We are complex beings that are often not capable of defining and rationalizing our way out of disturbing or disorienting situations.
