You shouldn't discriminate against women.
Nick is interviewing some male and female applicants for an open computer programmer position.
Nick wants to decide on a good applicant for the job.
Nick considers each applicant, both men and woman, and finally settles on a highly qualified woman.
Nick shortens his list down to the men, as men are typically programmers, then picks one.
The company does well because the woman Nick chose is an excellent programmer.
The company suffers because none of the men on the list were very good programmers.
