Stupidity

From http://www.gandalf.it/stupid/stupid2.htm
Stupidity is brainless – it doesn’t need to think, get organized or plan ahead to generate a combined effect. The transfer and combination of intelligence is a much more complex process.

Stupid people can combine instantly into a super-stupid group or mass, while intelligent people are effective as a group only when they know each other well and are experienced in working together. The creation of well-tuned groups of people sharing intelligence can generate fairly powerful anti-stupidity forces, but (unlike stupidity bundling) they need organized planning and upkeep; and can lose a large part of their effectiveness by the infiltration of stupid people or unexpected bursts of stupidity in otherwise intelligent people.
