I called the manifesto’s citations to findings about “average” women a “sleight of hand” for a very specific reason: While he dutifully includes that limiting language when making the citations, the policies he goes on to advance in the memo have no mathematically rigorous connection to those averages. He is deploying these dispassionate facts to argue for ending Google’s attempts at creating a fair and broadly welcoming working environment.
The author was not simply listing various items of scientific news at random, for the reader’s information only. He was building a case for ending specific, real programs that affect very real people. If his proposals were adopted, it wouldn’t be some abstract concept of “average” that doesn’t get a scholarship, it will be an actual individual woman.
