There’s a great TED talk from five years ago by Amy Cuddy. In it she describes how adopting certain kinds of physical poses can influence how people feel. The shorthand sometimes used is “power-posing,” an archetypal pose of confidence, a display that shows power. Research at the time suggested that adopting certain poses made people feel more confident, and also made people they were interacting with judge them to be more confident.
In the intervening five years there have been attempts to replicate the study or to look more deeply into the subject; they’ve raised questions, and that’s what science is supposed to do. But the core is still there: adopting physical poses can change how confident you are.
Now, I’m not writing today to say “pose like a superhero and you’ll feel awesome in the viva!” My main takeaway is a thought that has been in my mind for some time now, and which I’ve explored on the blog before. Confidence is not about hope: it’s not something you have or don’t, it’s not something mercurial that just comes and goes and you don’t know why.
There will be lots of things that trigger you in one way or another when it comes to how confident you feel. I think that for the viva you owe it to yourself, if you’re worried at all, to invest a little time exploring what could make a difference to how you feel. What can you do to make yourself more confident? For you it may not be about expansive physical stance, but there will be some conditions that help you more than others. Find them. Use them.
