Amy Cuddy's quick sharp way to deal with nerves is a TED classic. As a headhunter I would often call up anxious candidates just before they meet my clients. I had selected them and never put forward anyone that I thought could be anything less then fantastic. If they sounded like they could do with a bit of a boost I would often run through Amy's study and ask them to strike a pose. As a social scientist I can be a bit suspicious of research where I have not had the chance to interrogate the data. However antidotally it definitely helped. Maybe what helped was the idea that the nerves, anxiousness or fear was something that they could directly influence. What do you think?
