I admire Newsom for using her considerable talent to advocate for boys. But I worry that she is less concerned with helping boys than with re-engineering their masculinity according to specifications from some out-of-date gender-studies textbook. The trailer is suffused with males-are-toxic ideology but shows little appreciation for how boys’ nature can be distinctively good. The Mask You Live In is scheduled to be released later this year. Let’s hope there is still time for edits.

Here are a few suggestions:

1. Recognize that masculinity is more than a “mask”

The title and content of the film suggest that masculinity is a cultural creation. That is only marginally true. A lot of typical boy behavior, such as rough-and-tumble play, risk taking and fascination with gadgets rather than dolls, appears to have a basis in biology. Researchers have found, for example, that female monkeys play with dolls much more than their brothers, who prefer toy cars and trucks. Are male monkeys captive to a “guy code”? A recent study on sex differences by researchers from the University of Turin, in Italy, and the University of Manchester, in England, confirms what most of us see with our eyes: with some exceptions, women tend to be more sensitive, esthetic, sentimental, intuitive and tender-minded, while men tend to be more utilitarian, objective, unsentimental and tough-minded. We do not yet fully understand the biological underpinnings of these universal tendencies, but that is no reason to deny they exist.
