Taking the fourth spot on Big Think's 2019 top 10 countdown is the question: Evolutionarily speaking, is being gay still something of an enigma?
- Big Think's fourth most popular video of 2019 features bioethicist Alice Dreger. She presents the idea that heterosexual people have been less interesting to scientists than gay people in terms of why they exist. This is because, evolutionarily speaking, being gay doesn't lead to a higher "higher reproductive fitness" — meaning, it doesn't lead to more babies.
- Huge and rigorous studies have proven the fraternal birth order effect: Statistically, if a mother has lots of pregnancies of males, every successive male child will be a little bit more likely to be gay. This is because the mother's immune system appears to react to the male fetus' hormones and may dampen them down.
- The Western view of gay and straight isn't the definitive definition. In Samoan culture, there is a third gender: fa'afafine. These are boys who are raised as girls; they become women culturally and partner with men, although they don't change their physical anatomy.
Sally Susman explains how to use truth-telling moments to your future benefit.
- The biggest decision of Pfizer executive Sally Susman's life was to come out as gay in 1984, when society was not as accepting as it is now.
- She was told she would never have a spouse, a career, or children; those were the fears told to her by the people who loved her most.
- Defying that prediction became her personal north star, and 31 years later she has done it. Susman used that truth-telling moment of coming out as a way to focus her ambitions and plant the seeds for her future.
The surprising results come from a new GLAAD survey.
- The survey found that 18- to 34-year-old non-LGBTQ Americans reported feeling less comfortable around LGBTQ people in a variety of hypothetical situations.
- The attitudes of older non-LGBTQ Americans have remained basically constant over the past few years.
- Overall, about 80 percent of Americans support equal rights for LGBTQ people.
In most states, LGBTQ Americans have no legal protections against discrimination in the workplace.
- The Supreme Court will decide whether the Civil Rights Act of 1964 also applies to gay and transgender people.
- The court, which currently has a probable conservative majority, will likely decide on the cases in 2020.
- Only 21 states and the District of Columbia have passed laws effectively extending the Civil Rights of 1964 to gay and transgender people.
Evolutionarily speaking, being gay is still something of an enigma
- Heterosexual people have been less interesting to scientists than gay people, in terms of where they come from, because, evolutionarily speaking, being gay doesn't lead to a higher "higher reproductive fitness" — meaning, it doesn't lead to more babies.
- Across cultures, gay boys tend to be more interested in spending time with their mothers.
- We still don't really know why gay people are attracted to each other.
