The Dunning-Kruger club…

dkclub

Upshot: it takes a bit of intelligence, awareness and humility to be aware of your own intellectual limitations. If you think that your “common sense” overrides the opinion of experts who are talking about their field of expertise, you belong to the Dunning-Kruger club.

That might sound snarky, but there are times when I find myself as being too close to being in that club. Here is one such example:

Pass the sick bag. A device that allows people to empty a portion of their stomach contents into a toilet after a meal has just got the go-ahead from the US Food and Drug Administration. The device is approved for use by people who are severely obese, defined as having a body mass index of over 35 kg/m2.

The stomach-churning device, which is already available in some European countries, involves a tube being placed into the stomach in a short surgical procedure. The end of the tube contains a valve that lies flush against the skin.

Normally it is kept closed, but after meals, the person can connect the valve to another tube to drain about a third of their partially digested food into the toilet. It cannot remove more food than this, because the end of the internal tube is positioned higher than most of the stomach’s contents.

Manufacturer Aspire Bariatrics, based in Pennsylvania, says users need to chew their food well and eat more slowly to stop the 6 millimetre tube from getting blocked, and that this in itself helps reduce overeating.

“You get some solid chunks,” says Kathy Crothall, head of Aspire Bariatrics. “If a patient doesn’t chew their food very carefully they won’t get anything out of this device.”

The link contains a video and a description of the experimental results.

Now my emotional reaction is YUCK…THAT CAN”T BE GOOD FOR YOU (disclaimer: I used to weigh 320 pounds so this arouses some emotions in me). But I am not an expert in medicine and …IF this actually helps some people lead healthier lives…well, that is a good thing, despite my “yuck reaction”.
