I don't actually think that's reasonable. The next time you're watching a conversation, really pay attention to when people chime in. They may not interrupt mid-word, but they'll often take advantage of mid-sentence pauses, when the other person otherwise would have kept going. It's a natural part of discussion.

This is also why call latency can really destroy the quality of a discussion, even when its presence isn't obvious.

It isn't natural, it's part of the culture.

The worst I've seen was so bad that when I refused to interrupt, I waited 45 minutes without an opportunity to speak and then the meeting was over. Literally a 45-minute chain of people interrupting each other. That's not natural, that's adapted behavior.

Fortunately, it's a rarity at my current place of work :)

All it takes is a few bad apples and everyone else will adapt and interrupt as well.

Its very hard in a high latency call to not interrupt people.
