Wonder why so many people seem to be so dumb? Investing in real estate during a bubble? Smoking cigarettes? Falling for Internet scams? Maxing out credit cards at 20% interest?

The research tested the effects of polycyclic aromatic hydrocarbons (PAH). They get into the air from the burning fossil fuels or other organic substances such as tobacco. Motor vehicles are a major source of PAHs. So this research has sniffed out another urban problem, prevalent from Beijing to Mexico City, from Houston to Dubai.
