Not just any minimal barrier. Extroverts wired to speak spontaneously (i.e., have high Foxp2 gene expression) are the most likely to disrupt others for non-functional reasons. Requiring verbal communication to be initiated through written means is a great way to increase the signal-to-noise threshold for communication. Meanwhile, those who are not spontaneously verbal have a relatively low barrier (a sentence in chat).

Thank you, I have never seen that explanation and it certainly maps to behaviors that I've seen.

Interesting! Do you have further reading I might be able to consume?
