After President Joe Biden’s Supreme Court nominee Ketanji Brown Jackson was unable to define the word “woman” during her confirmation hearing on Tuesday — claiming she is “not a biologist” — USA Today outdid Jackson by arguing that even a “competent biologist” would be unable to “offer a definitive answer either.”

In an essay published in USA Today on Thursday, titled “Marsha Blackburn asked Ketanji Brown Jackson to define ‘woman.’ Science says there’s no simple answer,” USA Today reporter Alia E. Dastagir claimed that even experts in science lack a “sufficient way to clearly define” what a woman is.

“Scientists, gender law scholars and philosophers of biology said Jackson’s response was commendable, though perhaps misleading,” the author writes. “It’s useful, they say, that Jackson suggested science could help answer Blackburn’s question, but they note that a competent biologist would not be able to offer a definitive answer either.”

“Scientists agree there is no sufficient way to clearly define what makes someone a woman, and with billions of women on the planet, there is much variation,” she added.
