The Dr. is IN: error-management theory

Original image

Relationships: they're always a bit sticky, sort of like the outside of a honey jar. Even more sticky than an actual relationship can be the getting INTO a relationship. Does she like me? Does he think I'm fat? Why is she staring at my receding hairline? Am I wearing too much makeup?

Well here's some new scientific advice for all those looking to start relationships lifted straight from an old Frankie Goes to Hollywood song: RELAX.

According to this article in The Economist on a study recently published in Evolution and Human Behavior by Sarah Hill, a psychologist at the University of Texas, Austin, people of both sexes think the sexual competition they face is stronger than it really is.

Dr Hill showed heterosexual men and women photographs of people. She asked them to rate both how attractive those of their own sex would be to the opposite sex, and how attractive the members of the opposite sex were. She then compared the scores for the former with the scores for the latter, seen from the other side. Men thought that the men they were shown were more attractive to women than they really were, and women thought the same of the women. Dr Hill had predicted this outcome, thanks to error-management theory—the idea that when people (or, indeed, other animals) make errors of judgment, they tend to make the error that is least costly.

This explains why most men think a woman is coming on to them when all she is doing is being friendly. Trying but being rejected comes at little cost, except getting the old feelings hurt a bit. Whereas mistakenly believing she's not interested, and NOT trying to seduce her means, evolutionary speaking, the end of the human race.

The study also concluded that women undervalue signs that men are interested in commitment. "That, the idea goes, is because a woman who guesses wrongly that a man intends to stick around could end up raising a child alone."

So take heart followers of the _floss! And take some someone else's' heart while you're at it. The Dr. is out"¦

Fisherman Catches Rare Blue Lobster, Donates It to Science

Live lobsters caught off the New England coast are typically brown, olive-green, or gray—which is why one New Hampshire fisherman was stunned when he snagged a blue one in mid-July.

As The Independent reports, Greg Ward, from Rye, New Hampshire, discovered the unusual lobster while examining his catch near the New Hampshire-Maine border. Ward initially thought the pale crustacean was an albino lobster, which some experts estimate to be a one-in-100-million discovery. However, a closer inspection revealed that the lobster's hard shell was blue and cream.

"This one was not all the way white and not all the way blue," Ward told The Portsmouth Herald. "I've never seen anything like it."

While not as rare as an albino lobster, blue lobsters are still a famously elusive catch: It's said that the odds of their occurrence are an estimated one in two million, although nobody knows the exact numbers.

Instead of eating the blue lobster, Ward decided to donate it to the Seacoast Science Center in Rye. There, it will be studied and displayed in a lobster tank with other unusually colored critters, including a second blue lobster, a bright orange lobster, and a calico-spotted lobster.

Australian Scientists Discover First New Species of Sunfish in 125 Years

Scientists have pinpointed a whole new species of the largest bony fish in the world, the massive sunfish, as we learned from Smithsonian magazine. It's the first new species of sunfish proposed in more than 125 years.

As the researchers report in the Zoological Journal of the Linnean Society, the genetic differences between the newly named hoodwinker sunfish (Mola tecta) and its other sunfish brethren was confirmed by data on 27 different samples of the species collected over the course of three years. Since sunfish are so massive—the biggest can weigh as much as 5000 pounds—they pose a challenge to preserve and store, even for museums with large research collections. Lead author Marianne Nyegaard of Murdoch University in Australia traveled thousands of miles to find and collected genetic data on sunfish stranded on beaches. At one point, she was asked if she would be bringing her own crane to collect one.

Nyegaard also went back through scientific literature dating back to the 1500s, sorting through descriptions of sea monsters and mermen to see if any of the documentation sounded like observations of the hoodwinker. "We retraced the steps of early naturalists and taxonomists to understand how such a large fish could have evaded discovery all this time," she said in a press statement. "Overall, we felt science had been repeatedly tricked by this cheeky species, which is why we named it the 'hoodwinker.'"

Japanese researchers first detected genetic differences between previously known sunfish and a new, unknown species 10 years ago, and this confirms the existence of a whole different type from species like the Mola mola or Mola ramsayi.

Mola tecta looks a little different from other sunfish, with a more slender body. As it grows, it doesn't develop the protruding snout or bumps that other sunfish exhibit. Similarly to the others, though, it can reach a length of 8 feet or more. 

Based on the stomach contents of some of the specimens studied, the hoodwinker likely feeds on salps, a jellyfish-like creature that it probably chomps on (yes, sunfish have teeth) during deep dives. The species has been found near New Zealand, Australia, South Africa, and southern Chile.
