ABSTRACT
It costs money to find new employees, and employers naturally look for all possible ways of making the search more efficient. An employer generally has not the slightest interest in a prospective employee's TV viewing habits, for example, unless it can be shown that these habits are correlated with success or failure on the job. If, say, employees who watch as many as five situation comedies a week are estimated to be 10% more likely to fail in their jobs than others, the employer will compute exactly how much money can be saved by never hiring any situation comedy fan.
