On today’s Diane Rehm Show, Gabriel Sherman used an odd phrase, though not really an incomprehensible one. The topic of the morning was sexual harassment at Fox News, particularly on the part of former Fox News head Roger Ailes. Writer Sherman reported having heard stories from many women who had worked under Ailes over the years. Although the women had not spoken to one another, Sherman described their stories of harassment as remarkably similar. “And so,” he concluded, “I find their stories incredibly credible.” Although “incredibly credible” seems oxymoronic, it is clear that Sherman simply meant that the stories were exceedingly believable. (It is almost unbelievable how believable they are, under the circumstances.) He should have said something more straightforward.
