Keep Your Fingers Crossed: How Superstition Improves Performance: New research shows that having some kind of lucky token can actually improve your performance -- by increasing your self-confidence. ...Volunteers who had their lucky charm did better at a memory game on the computer, and other tests showed that this difference was because they felt more confident. They also set higher goals for themselves. Just wishing someone good luck -- with "I press the thumbs for you," the German version of crossing your fingers -- improved volunteers' success at a task that required manual dexterity.

~Of course, this is still a form of delusion. Everyone tested in the study was superstitious and had a lucky charm. I'd like to see a study or two that involved people who don't rely on superstition as well. I think if a person understands the delusion of superstition, they will therefore not need the "lucky" feather in their cap. They will have appropriate self-confidence based on their actual abilities. Still, it's an interesting study.

Traditional Aerobic Fitness Training Trumps Pedometer-Based Walking Programs for Health Benefits: What to do: walk around the block or work up a sweat in an aerobic workout at the gym? If you're looking for the best health benefits from an exercise program, a traditional aerobic fitness program that gets your heart pumping beats a walking program hands down. But if you want to get moving, a walking program is easier to do, it's good for you, and you're more likely to stick with it.

Wild Birds Opt for Conventional Food Over Organic: The nutritional benefits of organic food have been called into question by new research which shows wild garden birds prefer conventional seed to that which has been organically- grown. "Protein is an essential nutrient in the diet of all birds and mammals and getting enough of it -- especially in winter -- can be hard. "We showed that when given free choice, wild birds opt for the conventional food over the organic, and the most likely explanation is its higher protein content. "This study is only looking at one aspect of the organic food debate -- it does not take into account the long-term health implications of using chemical fertilisers and pesticides, or the often negative environmental impact of conventional farming; for example, other work has shown that pesticides can strongly reduce availability of seeds for birds. "But it does raise questions about the nutritional benefits of organic food and what consumers are being led to believe."
