A small, easily delivered, easiliy digested,
fact-shaped entity. Usually so
insignificant that it
doesn't matter if it is
true or not.
Most factoids convey fact. Some might say that the factoid was invented to train people not to ask for evidence behind information.
If the factoid efficiency ratio drops below 90%, cynicism grows, to where all factoids are questioned, and the disinformation packets are filtered out.
