The reason why I disagree is that presentation is a skill and introverts are more likely to be conscientious about their presentation, their mistakes, and put effort into patching them up over time. Even if it's their first go at it, they are likely to be conscientious about the content of their preso because they know they're going to suck at the live aspect (I'm an extrovert, btw). There might be a maturity aspect too, as in: when you're a high school or college student you are one-tracked to barf all of your knowledge onto the screen, probably due to insecurity, but that's uncorrelated to social temperament
