House M.D., March 14th 2011 episode: Taub uncovers information implying that a patient has plans to set off bombs at school. He and Masters discuss what to do with the information. The last line says it all.
Masters: What are you gonna do?
Taub: What do you think I should do?
Masters: So you can do the opposite? There are kids all over the country doing dumb, potentially violent things, but the percentage of them who would actually kill anybody is minuscule.
Taub: So I shouldn't do anything?
Masters: Mm... while the odds are low, the fallout could be huge. Tens or even hundreds of lives.
Taub: So I should call the cops.
Masters: Of course, over-identification with the subject could skew the calculation towards being over-protective. Or, alternatively...
Taub: You suck at this.
Masters: Hate the statistics, not the statistician.
