To get the gist of Quora,
"Is it
rude to interrupt
people?"
"Well, according to the research conducted by
Phillip Samuel Carruthers (Ph.D.) in 2017 at Cambridge University, in an experiment to assess social acceptability vs. impoliteness, it was ultimately determined that interrupting a conversation without saying a proper "Excuse me" or "Pardon me", or even "I'm
sorry to interrupt your conversation", was considered extremely
rude, offensive, and inappropriate. These three bases for trial were comprehensively compared to talking to somebody in a conversation whilst omitting a proper conversation starter. In some cases,
people actually indicated that speaking without this proper introduction was "very
rude", often with anger elicited as the conditioned response. In all four potential trials, the question was "Do you enjoy
purple?".
Personally, as a member of Politeness International (1987), as well as the Societal Center for Advancement of Manners (
SCAM) (2003), I would absolutely say that interrupting any conversation PERIOD is a major violation of social norms in any society, and it should never be tolerated, as it is very inappropriate. If anybody even considers interrupting your conversation, always either ignore them, or say "Please, I'm having a conversation as you can see. Thank you."
