This was basically folk knowledge when I was growing up in Brazil. Theater classes for teenagers were like 40% attractive people who want to make it as actors/60% awkward teens. From a basic trust in the scientific process (but also noting the limits of scientific psychology) I figure that social anxiety and the like are serious mental illnesses. But I immigrated as a three-year old and didn't know the language/make any friends for a while, so my social skills always lagged. Theater lessons (some of which was improv, but we wrote our own sketches for a capstone play for our own families) sort of helped me balance that. If there was any anxiety it was secondary/symptomatic of some underdeveloped stuff, much like people develop math anxiety. In retrospect, I attribute it to the "growth mindset" phenomenon: beginners make fools of themselves onstage whether they are awkward or easygoing, so you realize that being-comfortable-in-your-skin is something you can learn rather than something you were born without. Maybe this is what people are going to "hackathons" for - in a pressured time-boxed situation people are less likely to look down on the less math/programming-literate and help them instead.
