Helen Fisher: Why the 'Hot Vax Slutty Summer' Never Happened

A new survey of single people confirms that we have more sexual choices than ever.'s chief science adviser explains why such a libertarian outcome doesn't lead to libertinism.


Everywhere you looked this past spring, you saw stories about the preordained "hot vax summer" and "slutty summer" that was about to erupt in America like a long-simmering volcano of carnal desire.

Real and imagined experts predicted that single people, newly vaxxed and after a long, involuntary sexual pause due to COVID-19 lockdowns, would be on the prowl like some mix of the premenopausal Sex and the City girls, inmates freed after 18 months in solitary confinement, and the randy castaways of Love Island.

But like so many action films released in June, July, and August, the reality just didn't live up to the hype. While some observers say the reasons for "hot vax summer" going softer than Liberace at a speculum conference include the delta variant and the rise of online porn, Helen Fisher says it's simply because there's been a long, slow decline in one-night stands and hookup culture for years.

Fisher is an anthropologist who is the chief science adviser to, a senior research fellow at the Kinsey Institute, and the author of, most recently, a revised edition of Anatomy of Love (2016).

For each of the past 11 years, she's overseen Singles in America, an annual survey of more than 5,000 singles of every age, gender, and sexual orientation. Across the board, but especially among millennials and Generation Z, she says that "looks are out, emotional maturity is in. Stability is the new sexy." There are lots of reasons for this, but she cites younger people's interests in self-care as driving the changes along with the ever-rising options for women in education and work.

As women's status, earnings, and life opportunities have risen, says Fisher, they have become pickier about partners. Men, too, have changed, and are now more likely than women to say they want a long-term partner. They also want a partner who is well-educated, successful, and financially stable—the so-called George Clooney Effect. This new parity is reflected in one of the survey's most remarkable findings: An equal number of men and women say they faked orgasms in the past year.

Fisher talks with Nick Gillespie about the turn to what she calls "slow love" in an age of dating apps, the relief most men feel at not having to be the sole breadwinner, and why the rise of growing sexual opportunities is libertarian but not libertine.
