The experts generally don’t like to use simple, straightforward language when communicating ideas. You see it in meteorology as well as Covid; my opinion is that they seem to want to sound as smart as possible to their peers, rather than their audience, who then get lost and tune them out, leading said experts to be annoyed when they’re not listened to. Just my $0.02. I see it in sales and marketing, too. Don’t bore us, get to the chorus. .
