DO WOMEN AND men have different brains?

Back when Lawrence H. Summers was president of Harvard and suggested that they did, the reaction was swift and merciless.

Pundits branded him sexist. Faculty members deemed him a troglodyte. Alumni withheld donations.

But when Bruce Jenner said much the same thing in an April interview with Diane Sawyer, he was lionized for his bravery, even for his progressivism.

“My brain is much more female than it is male,” he told her, explaining how he knew that he was transgender.

Ms. Jenner was greeted with even more thunderous applause. ESPN announced it would give Ms. Jenner an award for courage.
