Speaking at Columbia j-school’s commencement yesterday, Fresh Air host Terry Gross tells why she gets better answers in interviews if (a) she urges subjects to draw the line when questions get too personal, (b) she lets them start over with their answers, and (c) she listens to what they say, even the boring parts. (Exception: People in politics aren’t eligible for the leeway of “a” and “b.”) Gross received the school’s highest honor, the Columbia Journalism Award.
