"psychology" news and stories

American craft beers keep upping the hops content, making them more and more bitter. But, reports Lizzie Buchen, in New Scientist magazine, humans have a universal dislike for bitter flavors. "Many bitter substances are at best nutritionally useless and at worst downright toxic," Buchen writes, "so we have evolved ways to protect ourselves. Placing a bitter foodstuff on the tongue will trigger a reflex reaction that encourages us to spit it out, or increase saliva flow to wash the taste away. A harmless bitter substance inserted directly into a person's stomach will generally induce nausea."

So why are we running after bitter beers with names like HopSlam?

Psychologists, chemists, neuroscientists and brewers offer Buchen a complex web of reasons, ranging from our craving to be considered connoisseurs to a basic love of carbs ("bitter, hoppy beers often have a higher content of sugar-releasing malts, making for a more intense carbohydrate fix"). And, of course, there's the old "benign masochism" that University of Pennsylvania psychologist Paul Rozin speaks about: pure and simple thrill-seeking, pushing ourselves to the limits of pain, for pure pleasure.

More Italians felt guilt about over-eating than they did about being untrue to their partners, according to the results of a study recently published in Riza Psicosomatica, an Italian psychology magazine. The roughly 1,000 Italians surveyed, ages 25 to 55, viewed sexual infidelity as a less serious offense than things like over-spending, neglecting friends and family, failing at work and, of course, over-eating. Many said that religion played little or no part in their decision-making.
