This has peaked in my circles, thankfully. Now it’s considered a bit of a faux pas to look up an answer during a discussion, for exactly this reason.
In my personal social circle, it's but faux pas to even take out your phone during a discussion, without a statement why. Not explicitly a rule, it just kinda evolved that way. “Ok, I need to know, I’m gonna check wiki” is enough, and honestly makes everything more engaging — “oh! What does it say? How many times DID Cellini escape execution?. Bring up the talk page that should be fun!”
