That's more or less the level of wrong that deepstack is. The Big 5 Personality Inventory is probably the most robust, reproducible piece of psychological science we've got, and while there might be arguments that it needs more nuance in places, the bare existence of introversion and extraversion as traits is not even slightly in question in the scientific community.
Your feeling that it might not be true—or that I'm "overly confident" in its truth—just doesn't hold up to decades of scientific consensus.
Gravity can be measured more objectively than social science (such as psychology) concept such as introvert/extrovert, which is determined by committees such as DSM IV or maybe now V. Introversion and extraversion are just one thing that is measured within a certain context.
