In the context of this thread and it's relevance to the real world,
I'm regaining an appreciation of the term "Half wit"...

Social media is becoming dominated by basically well educated articulate people, the + half of their wit;

but who have been convinced they are a superior elite of better informed experts than scientists and higher academics.

Their egotistical dogmatic belief in conspiracy theories is the - half of their wit.

These people are easily convinced and manipulated conformists,
who have been deeply programmed with an arrogant conviction
that it is the rest of sensible society who are the brainwashed sheeples..,!!!???
