Trying Not to Become Chaff

Something called the James S. McDonnell Foundation has a Web site it calls the Neuro-Journalism Mill, dedicated to tracking good and bad (mostly bad) reporting on neuroscience. It separates press reports into two categories — wheat and chaff — based on these criteria:

To be considered Chaff, the article must demonstrate one (or more than one) of the following flaws:

  • seriously misrepresents the original science
  • covers research of dubious value
  • wildly extrapolates the reported findings
  • presents an overly simplistic interpretation of a complex finding

Recent chaff includes:

“Men’s Brains Have More Cells, Say Scientists Who Counted”

“Cockroaches Can Learn — Like Dogs and Humans”

“Learn More About the Cognitive Paparazzi!”

“Why Do Most 16-Year-Olds Drive Like They’re Missing a Part of Their Brain?”

“Cells That Read Minds”

Among the wheat… this July 2 New Yorker piece on whether brain scans can really detect lies (short answer: not yet, not by a long shot).

It’s a fun site — though the authors don’t lie when they call themselves “curmudgeonly.” I’ll certainly be checking in with it regularly as I begin to write on this blog more about developments in neuroscience.

Still, I wonder if these folks aren’t trying to suck too much of the fun out of the entire endeavor of reporting on the leaps and bounds being made in understanding the human mind and human behavior. Sure, some of the headlines above take a serious field and force its findings into the template of the Weekly World News. At the same time, is any journalism that takes complex research and makes it accessible to non-academic readers a crime against science? Is joyless skepticism, as opposed to guarded optimism (or even wonderment), the only acceptable tone for one to take?

It could be the case that such an approach is necessary. These are very tough topics for people to grapple with intellectually. A recent study (PDF) suggests that “people are much more willing to buy bad scientific explanations of phenomenon if they contain some sort of neuroscience reference - such as a comment that the phenomenon is associated with activity in a certain part of the brain - even if that reference is irrelevant to the logic of the argument being made.” It’s something to keep in mind as a reader, a reporter, or a writer.

Still, I think with a little more knowledge on the part of the reader — more education in basic neuroscience, as with economics, would be a good idea at the high school level — most of the sillier stories would stop being believed. Meanwhile, there’s plenty in the field to be excited about, even keeping it all in perspective.

Don’t Click It

Sort of a double recommendation here tonight…

First, cruise on over to www.dontclick.it. It’s an ingenious art project (mouse over where it says “copyright” to get some explanation), based on the idea that user interfaces on the Web would (or at least could, under some circumstances) be better without “clicking.” As in… well, it’s sort of difficult to put into words. But you’ll get it in 10-30 seconds if you play with the site. I’m not sure I buy the concept — though it’s not being helped by the fact that I’m using a laptop touchpad at the moment — but it’s intriguing and could be used for at least some types of sites.

And how did I stumble upon this odd, fascinating site? Did a blog recommend it? Did it come up in a search result? Did Microsoft pay to put it in front of me? Nope, nope, and nope. I found it using a little tool called StumbleUpon. You download a toolbar, give it a few topics you’re interested in, and then hit a button that says “Stumble!” It sends you to sites, which you can rate with a thumbs up or a thumbs down. It collects data on what kinds of sites you like and creates recommendations — a bit like Amazon’s recommendations, I suppose, but for the whole Web.

This is my first, oh, half an hour using StumbleUpon. But I like it so far. And it could be a great tool when bored of my usual virtual haunts.

I found it, via GeekPress.

Simpsonize Me

Proving that I’m simply up later than I should be, I’ve started playing with the “Simpsonize Me” site my wife alerted me to earlier today. (If you want to know what a bunch of editors at a big paper were doing this afternoon…)

Anyway, I’m not sure this looks anything like me, but it’s what you get when you upload a picture of me and press the colorful button on the site.

As a virtually lifelong fan (keeping me from a perfect record: It didn’t exist when I was born.), I still have yet to see the movie. But the folks over at Burger King and Twentieth Century Fox Film Corporation sure came up with a viral site.

Ted Stevens Is Not in on the Joke

From infants to old people…

Old people (such as Alaska’s senator, Ted Stevens, pictured above) have a reputation for sometimes being grumpy and humorless. Well, now there’s some scientific research to back that up.

A new study out of Washington University in St. Louis looks at how general cognitive decline leads to a loss in humor comprehension:

Humor comprehension in older adults functions in a different fashion than humor comprehension in younger adults. The researchers studied older adults from a university subject pool as well as undergraduate students. The subjects participated in tests that indicated their ability to complete jokes accurately as well as tests that indicated their cognitive capabilities in areas of abstract reasoning, short-term memory, and cognitive flexibility. Overall, older adults demonstrated lower performance on both tests of cognitive ability as well as tests of humor comprehension than did younger adults.

The experiment was conducted, in part, by having test subjects complete a “joke stem” “correctly”: “A joke stem was presented with four different endings including the correct humorous ending; a humorous nonsequitur—an ending that does not make sense with the joke stem but is funny in and of itself; an unhumorous straightforward answer; and an unhumorous, unrelated nonsequitur. The correct ‘funny’ answer required that the participant integrate the three different cognitive measures tested in the study—abstract reasoning, short -term memory, and cognitive flexibility.”

I’d love to see the jokes they used. (Did they haul out the old “Soup or Sex” chestnut?)

While it’s easy to make fun of, though, this strikes me as important research. People don’t lose their sense of humor because they get old and/or crotchety. They literally lose their sense of humor, like one loses one’s hearing or one’s eyesight, though in this case due to a general decline in cognitive function. I’m not sure this means we’re close to a cure for “grumpy old man syndrome”; but we’re headed in something like the right direction.

For Senator Stevens, however, I fear we’re too late.

Infants Know What You’re Thinking

Knowing that others have minds and being able to comprehend their thinking is one of the things that makes us human. However, scientists have yet to come to a consensus as to how early we acquire this ability. The results of a new experiment may indicate that we gain this ability earlier than previously thought:

In two experiments, the researchers had the infants [13 months] watch a series of animations in which a caterpillar went in search of food (either a red apple or a piece of cheese) that was hidden behind a screen. In some scenes, the caterpillar could see a human hand situating the food, but in others there was no hand to drop a hint. The caterpillar was either successful finding the preferred food behind the correct screen, or went behind an alternative screen with the other type of food behind it.

When the caterpillars didn’t do what one would expect — going to one screen despite seeing the human hand place the desired food behind the other — infants tended to look at the animation longer, suggesting puzzlement about the caterpillar’s actions. “This result,” says Surian, “Suggests the infants expected searches to be effective only when the [caterpillar] had had access to the relevant information.”

If the experiment’s design is sound, this means that “infants who expect agents’ behavior to be guided by such internally available information thereby exhibit an ability to attribute mental content — and this is mind reading proper, however rudimentary.”

Architectures of Control

A blog I’ve gotten into recently is Architectures of Control, which looks at, well, architectures of control — how design is used to guide (or control) people’s actions. Today, the blog notes this scam:

The hope, apparently, is that visitors can be guided through an amusement arcade. But, as the author notes, it’s a pretty transparent ruse — you can see clearly that it’s possible to simply go around the building.

I couldn’t help being reminded of this Onion story:
