Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.
Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, one or more will very likely be unemployed.
Sharon's argument relies on the assumption that
normal levels of unemployment are rarely exceeded
unemployment is not normally concentrated in geographically isolated segments of the population
the number of people who each know someone who is unemployed is always higher than 90 percent of the population
Roland is not consciously distorting the statistics he presents
knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics
B的意思是，失业率并不会集中在某些地理位置上分布的地区，而是均匀分布的，所以不会有地域特性，是具有普遍性的。
