  • Episode 426: Why Sex Ed Sucks (And Always Has)
    Aug 26 2025

    Sex education is highly controversial. Last year alone, 27 US states introduced bills aimed at restricting sex ed! However, this fight over what sex ed should cover (and whether it should even be taught at all) is nothing new. We’ve been having the same fights about sex ed for over a century, and that’s a big part of the reason why modern sex education still sucks.

    I’m joined today by Margaret Grace Myers, a writer, researcher, educator, and former bookseller based in Maine. She is the author of the new book The Fight For Sex Ed: The Century Long Battle Between Truth and Doctrine.

    Some of the specific topics we explore include:

    • Why do we keep having the same arguments about sex ed?
    • What really holding sex education back?
    • How did abstinence become such a dominant part of sex education in the US?
    • Does abstinence education actually work as intended?
    • Why is it so hard to access comprehensive sex education when it’s what most parents say they want?

    You can check out Margaret’s website to learn more about her work.

  • Episode 425: What Determines Our Sexual Orientation?
    Aug 22 2025

    Why are some people straight while others are gay or bisexual? What determines our sexual orientation anyway? Today, we’re going to be diving into what we’ve learned about the biological origins of our sexuality from decades of scientific research. As you’ll see, there’s not a simple and easy story—it doesn’t boil down to something like a “gay gene.” It’s way more complex than that!

    I am joined once again by Nathan Lents, a Professor of Biology at John Jay College, where he is the director of the Cell and Molecular Biology program. His research lab studies human genetic evolution and forensic DNA technology. He also writes popular science articles and is the author of the new book The Sexual Evolution: How 500 Millions Years of Sex, Gender, and Mating Shape Modern Relationships.

    Some of the specific topics we explore include:

    • Is same-sex attraction genetic?
    • How can two people who share 100% of the same DNA have different sexual orientations?
    • When researchers are studying sexual orientation, should they be looking at attraction, identity, behavior, or all of the above?
    • Why is having more older brothers linked to greater odds of homosexuality in men?
    • What other biological factors are associated with sexual orientation?

    You can check out Nathan’s website to learn more about his work.

  • Episode 424: Are Humans Made To Be Monogamous?
    Aug 19 2025

    Are human beings made for monogamy or non-monogamy? This is a popular subject of debate. While some argue that humans evolved for monogamy in order to ensure parental investment in our offspring, others argue that humans evolved to be non-monogamous because it increases the odds of reproductive success and genetic diversity in our species. So which is it? That’s what we’re going to be talking about today.

    I am joined by Nathan Lents, a Professor of Biology at John Jay College, where he is the director of the Cell and Molecular Biology program. His research lab studies human genetic evolution and forensic DNA technology. He also writes popular science articles and is the author of the new book The Sexual Evolution: How 500 Millions Years of Sex, Gender, and Mating Shape Modern Relationships.

    Some of the specific topics we explore include:

    • What’s the difference between social monogamy and sexual monogamy?
    • How common are social and sexual monogamy in both humans and animals, and how often do they overlap?
    • Can research on other primates shed light on how human mating strategies evolved?
    • Can someone’s brain chemistry predispose them to being monogamous or non-monogamous?

The episode was really great. I was thinking about things that I didn’t know were even real. The sex points system and honestly I just figured that after a while of being with someone for a long time you would kind of slow down. But no that isn’t how it should work...

Great Episode
