Since when has it been socially acceptable for midwits to pretend they understand science?

"Trust the scioence" has become the boiler plate political slogan that roughly approximates to saying that someone should take the same leap of unjustified faith in a given position that they were told to believe by some talking head in media. Do these people actually believe they came to some kind of scientific understanding, or are they self aware enough to realize they are scientifically illiterate retards using a catchy slogan to virtue signal?
