Human Biodiversity is united by the knowledge that human genetic variations are far more important for human society than is commonly accepted, and we welcome all members willing to civilly discuss such topics, topics including human genetic engineering, transhumanism, eugenics, dysgenics, heritability of psychological variants, psychological sex differences, human biodiversity (HBD), biological human races, and sociopolitical positions related to such topics, both Left and Right. The SIG is open to Mensans, ex-Mensans, members/ex-members of other credible high-IQ societies, and those who have attended graduate school. Otherwise, diversity of every sort is accepted.


M-Atheists International SIG icon
This e-SIG is for members of Mensa who freely admit to being atheists and wish to share their ideas and experiences with other Mensan atheists. Which happened first - you knew you were smart, or you knew you didn't believe in godstuff? How do you deal with friends and family who are believers? Do they all know you don't believe? Do you feel better nowadays about admitting you're an atheist? Please share what you know.
