There exists no test - for 'Stupidity".
Those afflicted are unable to judge themselves due to their 'condition'.
And as such, are unable to accept any 'judgement' other than their own innate, inborn, superiority, arrogance, elitism,
and absolute adherence to the DPST/ccp absolute rule of chairman Xi over themselves as nomenklatura - lording over the rest of the plebes in their Socialshit Amerika.
