In a more recent study, published in the Journal of Neuroscience in August, 2014, researchers from Dartmouth and New York University showed that our brains take just three hundredths of a second, much less time than an eyeblink, to decide trustworthiness. In fact, our judgments about trustworthiness are so rapid that we are able to make them even before we know who the person is! The researchers showed people photos of both real faces and computer-generated faces deliberately designed to look either trustworthy or untrustworthy. Results showed that we judge people with high eyebrows and prominent cheekbones as trustworthy, while we distrust people with furrowed brows and sunken cheeks. There is no evidence that these characteristics actually make people more or less trustworthy in real life!
