Afaik no. Introverts can be both very good at social cues and bad at them. Same goes for extroverts. Introversion vs extrovertion is just one of huge amount of traits we have.

Also, it ia not like there would be two distinct species. It is scale and majority of the people are in the middle between extroversion and introversion. Just slightly biased toward one side.

The distinction between "introvert" and "extrovert" is really about whether socializing is draining or recharging.

I'm extremely introverted and plenty "good at" (most forms of) socializing. It's also hard work for me. But it's hard work like going on a mountain hike is hard work: it's a fantastic experience (usually) and I am glad I do it, but I also simply can't do it 24/7/365.
