Are Extroverts or Introverts More Likely to Face FOMO?

I'd love to get your opinion on this one. I've been writing about FOMO (fear of missing out) all this week, and I've been looking at it mainly from the point of view of the digital lifestyle. This is mostly because I don't experience FOMO for many "real-life" events. I'm happy to stay home and chill out in a lot of cases. My wife, on the other hand, is completely opposite. If she sees a crowd, she wants to know what's going on, and she wants to be a be in the middle of it. But, of course, she behaves that way because she is 100% extrovert.

This leads me to my question.

Do you think extroverts or introverts are more likely to have a fear of missing out? I'm talking about FOMO in "real-life" and online interactions. Are introverts more likely to keep to themselves in digital realms, as well? Or do introverts finally get their chance to shine online?

I have anecdotes that apply to this discussion, but they're hardly proof of any widespread behavior patterns.

So I'm looking to you, Internet. What do you think?
