Two self-fulfilling prophecies are stronger, and more harmful, than one

Time and again, research has demonstrated the power of an individual's self-fulfilling prophecies if you envision yourself tripping as you walk across a stage, you will be more likely to stumble and fall. New evidence suggests that previous studies have underestimated not only the effect of our own negative prophecies, but also the power of others' false beliefs in promoting negative outcomes.

When two or more people have similar false beliefs about another person, it's possible this could influence the person's behavior. Researchers Stephanie Madon, Max Guyll, Richard Spoth, and Jennifer Willard, all at Iowa State University, examined this phenomenon to see how much influence those collective beliefs have in determining a positive or negative reality.

Flashback The Moral Instinct

Which of the following people would you say is the most admirable: Mother Teresa, Bill Gates or Norman Borlaug? And which do you think is the least admirable? For most people, it's an easy question. Mother Teresa, famous for ministering to the poor in Calcutta, has been beatified by the Vatican, awarded the Nobel Peace Prize and ranked in an American poll as the most admired person of the 20th century. Bill Gates, infamous for giving us the Microsoft dancing paper clip and the blue screen of death, has been decapitated in effigy in "I Hate Gates" Web sites and hit with a pie in the face. As for Norman Borlaug . . . who the heck is Norman Borlaug?

Yet a deeper look might lead you to rethink your answers. Borlaug, father of the "Green Revolution" that used agricultural science to reduce world hunger, has been credited with saving a billion lives, more than anyone else in history. Gates, in deciding what to do with his fortune, crunched the numbers and determined that he could alleviate the most misery by fighting everyday scourges in the developing world like malaria, diarrhea and parasites. Mother Teresa, for her part, extolled the virtue of suffering and ran her well-financed missions accordingly: their sick patrons were offered plenty of prayer but harsh conditions, few analgesics and dangerously primitive medical care.

Is Our Fear of Germs Bad for Our Health?

The chemical industry has helped fortify our homes against microbial invasion. But is our fear of germs making us even sicker?

The "vomiting virus" now sweeping across Britain may be headed our way. At the same time, San Francisco is being hit with a new strain of the nasty bacterium known as MRSA (methicillin resistant Staphylococcus aureus) -- this one responsible for "flesh-eating pneumonia."

Meanwhile, four patients were recently isolated in the University of Maryland Medical Center, infected with a multidrug resistant bacterium called Acinetobacter baumannii, which has attacked a number of Afghanistan war veterans. As one doctor said of the that bug, "When these people get infected ... you sort of say this is the last straw."

Those new menaces, and more, are joining the usual biological villains that lurk everywhere in midwinter.

Even more than in past years, we're turning to the chemical industry for help in fortifying the American home against microbial invasion. Few go as far as Jacques Niemand, a reclusive Briton who was killed last May by fumes rising from vast quantities of disinfectant that he kept in open buckets around his house to ward off infection. But lower-intensity chemical warfare on our invisible housemates is in full swing.

Research suggests why scratching is so relieving


Wake Forest University Baptist Medical Center
Thu, 31 Jan 2008 17:38 UTC
In the first study to use imaging technology to see what goes on in the brain when we scratch, researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving - and why it can be hard to stop. The work is reported online in the Journal of Investigative Dermatology and will appear in a future print issue.

"Our study shows for the first time how scratching may relieve itch," said lead author Gil Yosipovitch, M.D., a dermatologist who specializes in itch. "It's important to understand the mechanism of relief so we can develop more effective treatments. For some people, itch is a chronic condition that affects overall health."

The study involved 13 healthy participants who underwent testing with functional magnetic resonance imaging (MRI) technology that highlights areas of the brain activated during an activity. Participants were scratched on the lower leg with a small brush. The scratching went on for 30 seconds and was then stopped for 30 seconds - for a total of about five minutes.
