Add sneezing to the list

Recently, I blogged about how lemon-scented Windex and AC-DC music can affect the results of economic experiments. We can now add another factor to that list: sneezing.

Researchers in Michigan found that a pollster who sneezed before handing over a survey about health led to lower approval of the American health care system and predictions of lower health outcomes for Americans by survey respondents than when the pollster didn't sneeze.

Thanks to the Freakonomics blog for this one.
