Lots of young EAs are struggling with the issue of whether, when, where, and how to have kids, and whether becoming a parent will undermine being an Effective Altruist, in terms of opportunities costs such as career, time, energy, money, focus, and values.
For whatever it's worth, I'm happy to answer any questions you might have about parenting -- its pros and cons, ethics, practicalities, etc.
Background: I'm a 57-year-old dad; I've raised a 26-year-old daughter and a 6-month-old baby. I've also helped raise a teenage step-son, and I come from a big, close-knit family (I have about 30 cousins.) I've lived as a parent in the US (mostly), UK, and Australia. I'm also a psychology professor who's taught courses on parenting-relevant topics such as behavior genetics, educational psychology, evolutionary psychology, human intelligence, evolutionary game theory, and decision making. I've been involved in EA for the last 6 years, and I have a pronatalist orientation, with an interest in population ethics, reproductive bioethics, gamete donation, and cognitive and moral enhancement. I'm not an expert on every practical or scientific issue about parenting, but maybe my perspective could be useful to some EAs.
There's a standard saying that 'half of all marriages end in divorce'. That's an outdated overestimate, and the divorce rate is much, much higher for people who don't graduate college, and who are pregnant/have a kid before getting married.
Among women with a college education, at least 78% of marriage last at least 20 years.
This number is probably even higher if they wait til after college graduation to get married, if they aren't pregnant/have a kid before marriage, if they don't cohabit for a long time before marriage, and if they're reasonably high in agreeableness, and low in neuroticism
