When life calls on us to project confidence, whether you're going in for a major job interview, pitching investors or networking at a big conference, the old adage is just to fake it until you make it. But a new study from New York's Cold Spring Harbor Laboratory released this week looks at whether the human feeling of confidence can be broken down into objective mathematical calculation. Choices that are big, such as launching a new venture, or small, such as deciding when to merge onto the highway, all require a careful weighing of the risks involved. Of course, some of these judgement calls have to occur faster than others. The study's lead author, associate professor of neuroscience Adam Kepecs, explained the driving question behind the research.
