What’s more, a 2017 study led by Emory University researchers discovered, among other things, that fathers also sing and smile more to their daughters, and they use language that is more “analytical” and that acknowledges their sadness far more than they do with their sons. The words they use with sons are more focused on achievement — such as “win” and “proud.” Researchers believe that these discrepancies in fathers’ language may contribute to “the consistent findings that girls outperform boys in school achievement outcomes.”

After visits to the emergency room for accidental injuries, another study found, parents of both genders talk differently to sons than they do to daughters. They are nearly four times more likely to tell girls than boys to be more careful if undertaking the same activity again. The same study cited earlier research which found that parents of both genders used “directives” when teaching their 2- to 4-year-old sons how to climb down a playground pole but offered extensive “explanations” to daughters.

Even boys’ literacy skills seem to be impacted by the taciturn way we expect them to speak. In his book “Manhood in America,” Michael Kimmel, the masculine studies researcher and author, maintains that “the traditional liberal arts curriculum is seen as feminizing by boys.” Nowhere is this truer than in English classes where, as I’ve witnessed after more than 20 years of teaching, boys and young men police each other when other guys display overt interest in literature or creative writing assignments. Typically, nonfiction reading and writing passes muster because it poses little threat for boys. But literary fiction, and especially poetry, are mediums to fear. Why? They’re the language of emotional exposure, purported feminine “weakness” — the very thing our scripting has taught them to avoid at best, suppress, at worst.

Women often say they want men to be emotionally transparent with them. But as the vulnerability and shame expert Brené Brown reveals in her book, “Daring Greatly,” many grow uneasy or even recoil if men take them up on their offer.

Indeed, a Canadian study found that college-aged female respondents considered men more attractive if they used shorter words and sentences and spoke less. This finding seems to jibe with Dr. Brown’s research, suggesting that the less men risk emoting verbally, the more appealing they appear.
