The examined spy

That’s the title of an article by Thanassis Cambanis about IARPA’s efforts to improve the accuracy of forecasting- and effort that’s funding the Good Judgment Project, which I’m involved in.

In a field still deeply shaped by arcane traditions and turf wars, when it comes to assessing what actually works — and which tidbits of information make it into the president’s daily brief — politics and power struggles among the 17 different American intelligence agencies are just as likely as security concerns to rule the day.

What if the intelligence community started to apply the emerging tools of social science to its work? What if it began testing and refining its predictions to determine which of its techniques yield useful information, and which should be discarded?… “We still don’t really know what works and what doesn’t work,” said Baruch Fischhoff, a behavioral scientist at Carnegie Mellon University. “We say, put it to the test. The stakes are so high, how can you afford not to structure yourself for learning?”…

Fischhoff and a who’s who of social scientists from psychology, business, and policy departments hope to foment a similar revolution in the intelligence world. Their most radical suggestion could have far-reaching effects and is already being slowly implemented: systematically judge the success rates of analyst predictions, and figure out which approaches actually work. Is intuition more useful than computer modeling? Is game theory better for some situations, and on-the-ground social analysis more accurate elsewhere?…

That remains only a proposal so far, but the Intelligence Advanced Research Projects Activity, or IARPA — a two-year-old agency that funds experimental ideas — is already trying a novel way to generate imaginative new steps to make predictions better. It is funding an unusual contest among academic researchers, a forecasting competition that will pit five teams using different methods of prediction against one another.

Of course, one can argue- and indeed many of my fellow futurists will argue- about what constitutes a “working” forecast, and some may go so far as to claim that even a completely wrong forecast can be useful under the right circumstances.

Memory improvements after bariatric surgery

Yes, it sounds a bit like an obscure joke, but via Future Pundit comes this new piece of research suggesting “a link between weight loss and improved memory and concentration.” From the abstract:

Growing evidence has shown that obesity is associated with poor neurocognitive outcomes. Bariatric surgery has been shown to be an effective intervention for morbid obesity and can result in improvement of many co-morbid medical conditions that are associated with cognitive dysfunction. The effects of bariatric surgery on cognition are unknown….

We performed a prospective study total of 150 subjects (109 bariatric surgery patients enrolled in the Longitudinal Assessment of Bariatric Surgery project and 41 obese control subjects who had not undergone bariatric surgery). These 150 subjects completed a cognitive evaluation at baseline and at 12 weeks of follow-up. The demographic, medical, and psychosocial information was also collected to elucidate the possible mechanisms of change. [S]urgery patients had improved memory performance at 12 weeks of follow-up… The present results suggest that cognitive impairment is common in bariatric surgery patients, although these deficits might be at least partly reversible. Future studies are needed to clarify the underlying mechanisms, in particular, longitudinal studies using neuroimaging and blood markers.

I’ll have “white men are the real minority” with a side of Sichuan pork

Joshua Green in the Atlantic, on "class warfare:"

I've always loved that phrase because it's such potent hyperbole, the product of expensive focus grouping and crafty political wordsmithery as surely as is the phrase "millionaires and billionaires," except "class warfare" has that extra dimension of apocalyptic consequence and the undertone of victimization that work so well together even though they shouldn't, like sweet-and-sour soup.

Quote of the day: Same planet, different worlds

From the New York Magazine article on bottle service:

"Some of the girls definitely think, 'He’s going to fly me to California and make me his wife!' But then most of them are just like, 'Guess who I just did in the bathroom?' "

Ummm. Wow?

It actually gets better, and if the whole piece were a song, it would be Steely Dan's "Everything Must Go" playing in a small club around 1 a.m.

Kelly… is hooking up with a 20-year-old male model but he’s not here tonight and she’s got her eye out for something else. Girls like her are either dating older men with money or young and good-looking ones without. There is a stupendous symmetry to this. The rich old men want to be young and good-looking and the young ones want to be rich, but both are sleeping with the same girl….

The exchange happens like this. A girl will say to a guy she has not slept with yet, but perhaps they have kissed or she’s let him touch her, "I'm short on my rent" or "There's this dress I really want." After sleeping with him a few times, she might say, "I need a tan. I should go to Miami." The beauty is in the subtle gaucheness.

Larry Swedroe on “Why Experts Fail Us”

CBS MoneyWatch blogger Larry Swedroe glosses David Freedman's Wrong and Philip Tetlock's Expert Political Judgment to explain why expert advice goes wrong, and why experts have incentives to oversell their certainty and expertise:

Most of us want certainty, even when we know, logically, that it doesn’t exist. With investing, it’s a desire to believe that there’s someone who can protect us from bear markets and the devastating losses that can result. However, we’ve seen on numerous occasions that experts simply aren’t that expert. Of course, the next question is: “Why?”

Robert Darnton on “a font of proverbial nonwisdom”

Robert Darnton challenges “five myths about the information age” that, taken together, “constitute a font of proverbial nonwisdom.”

  1. “The book is dead.” Wrong: More books are produced in print each year than in the previous year.
  2. “We have entered the information age.”… [E]very age is an age of information, each in its own way and according to the media available at the time.
  3. “All information is now available online.” The absurdity of this claim is obvious to anyone who has ever done research in archives.
  4. “Libraries are obsolete.” Everywhere in the country librarians report that they have never had so many patrons.
  5. “The future is digital.” True enough, but misleading.

It used to be said that the difference between God and Robert Darnton was that God was everywhere, while Darnton was everywhere but Princeton. Now that he’s Harvard’s university librarian, I wonder if the joke has migrated and updated?

Chris Mooney on “motivated reasoning” (i.e. biased reasoning)

Chris Mooney has a good article in Mother Jones on "the science of why we don't believe science"- why and how we manage to believe sometimes-outlandish things in the face of contrary evidence.

[A]n array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president, and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.

The theory of motivated reasoning builds on a key insight of modern neuroscience: Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close….

We're not driven only by emotions, of course—we also reason, deliberate. But reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about.

As he puts it, "We apply fight-or-flight reflexes not only to predators, but to data itself."

It's well worth reading, and it makes me wonder how to square insights like these against claims about the value of brainstorming, which is supposed to be good because its speed and social character forces you past the normal social and logical barriers that keep you from being creative.

Prize

Last week I heard that my “Futures 2.0” article has been recognized with an outstanding paper award:

Every year Emerald invites each journal’s Editorial Team to nominate what they believe has been that title’s Outstanding Paper and up to three Highly Commended Papers from the previous 12 months. Your paper has been included among these and I am pleased to inform you that your article entitled “Futures 2.0: rethinking the discipline” published in foresight has been chosen as an Outstanding Paper Award Winner at the Literati Network Awards for Excellence 2011.

It’s not as competitive or mysterious or lucrative as, say, the Macarthur (call me, guys); but still it’s a nice little piece of recognition.

The list of 2010 winners is here; it looks like the 2011s will all be posted soon.

Nice. Now back to work.

What inspired this piece of research?

Submitted without comment:

Patrick Markey, Charlotte Markey, “Pornography-seeking behaviors following midterm political elections in the United States: A replication of the challenge hypothesis,” Computers in Human Behavior, v. 27 n. 3 (May 2011).

The current study examined a prediction derived from the challenge hypothesis; individuals who viciously win a competition of rank order will seek out pornography relatively more often than individuals who viciously lose a competition. By examining Google keyword searches during the 2006 and 2010 midterm elections in the United States, the relative popularity of various pornography keyword searches was computed for each state and the District of Columbia the week after each midterm election. Consistent with previous research examining presidential elections and the challenge hypothesis, individuals located in traditionally Republican states tended to search for pornography keywords relatively more often after the 2010 midterm election (a Republican victory) than after the 2006 midterm election (a Democratic victory). Conversely, individuals located in traditionally Democratic states tended to search for pornography relatively less often following the 2010 midterm election than they did following the 2006 midterm election.

The power of the social sciences!
