Responding to sound bites are how 95% of the population function.
Take a group whose main driver is appetite, and who respond to extraneous influences with impulse reactions, and that's your average.
The arrogance of plenty of so called educated people is that they believe their academic qualifications and self anointed intellectual superiority, gives their own particular 'impulse' judgements validity. When they are no more informed than anyone about, well, anything much.
Problems occur since these very same people are in a position to screw up in situations which involve others.
