"Four out of five" has become significant in terms of statistical interpretation.
It's even crossed into urban mythology; the 80/20 rule, or 80% of production comes from 20% of the workforce, etc.
For anyone who has volunteered in your community's literacy project, you perhaps are aware of the US statistic that reveals that 20% of the adult population is functionally illiterate--can't read the instructions on a prescription bottle, can't understand a menu in a restaurant, can't comprehend anything mailed to them. This is a genuine and troubling statistic.
And as we all have experienced here, the conclusions the remaining 80% reach as a result of their bias result in a great deal of conflict.
The fifth Iraqi, by the way, is the one shooting at and killing American soldiers.
(It's that damned 20% in the minority that always seems to drag the rest of us down...
