"... over-stimulation and excessive meetings can easily stunt their full brain power. One study showed that when introverts and extroverts are given math problems to solve with various levels of background noise playing, introverts do best when the noise is lower, while extroverts perform better with louder noise...."
How about all the classrooms and test rooms? If it's really true that performance is affected, then introverts are systematically discriminated against in getting into schools and onto career paths. But to view this as a condition deserving accommodation would be awfully expensive or — if you let people work from computers in their home space — vulnerable to cheating.
