Study Shows Faces Sway Voters
What voters -- at least young voters -- want most in their elected officials is the appearance of competence, suggests a study by Princeton University researchers and students.
"When we ask what is the most important characteristic in a person running for public office, it's competence," Princeton University psychology professor Alexander Todorov said, adding that in their survey of Princeton undergraduate and graduate students, competence beat out qualities such as trustworthiness and emotional stability.
But how do these voters decide who is more competent?
Todorov and his students flashed at least 15 pairs of images of competing House and Senate candidates before each of their 840 volunteers and asked them to choose which one looked more competent. They then checked on how the elections came out and found that the candidates identified as more competent-looking by a majority of the volunteers in each contest won 71.6 percent of 2004 Senate races and 66.8 percent of House races that year. They reported the results in the June 10 issue of the journal Science.
The findings are significant, Todorov said in an interview, because they showed that "a minimal amount of information" can be a powerful predictor of election outcomes. These kinds of quick, unreflective judgments can influence voters' attitudes, even as analysts focus more on factors such as party affiliation or the candidates' positions.

In Vitro Babies Grow Taller
Babies born through in vitro fertilization tend to be taller than those conceived naturally and may be less prone to heart disease, new research suggests.
Harriet Miles of the University of Auckland in New Zealand compared 50 6- and 7-year-old children who had been conceived using IVF with 60 conceived naturally. The IVF children tended to be taller than those conceived naturally when the researchers calculated what their height would be expected to be based on their age and parents' height, the researchers reported last week at a meeting of the Endocrine Society in San Diego. In addition, the IVF children had higher levels of growth hormones in their blood.
The researchers also found that the IVF children tended to have higher levels of high-density lipoprotein, or HDL, the "good cholesterol" because it helps remove low-density lipoprotein, the "bad cholesterol."
Miles speculated that there is something about the IVF process that alters genes in subtle ways through a process known as "imprinting."
