alt Hacker News>This is a completely derivative conclusion from something I learned in molecular biology as an undergrad. The only "new" thing here is saying that poor people live in environments, since we've known for literally decades that DNA methylation is affected by environment.
It's one thing to theorize a causal relationship, but informed policy-making needs actual data that can only be obtained by legwork. What aspects of the social/cultural environment are we talking about? What genes are being expressed differently? What are their estimated health or economic impacts?
It wasn’t a “theory” (at least no more than any other scientific fact), and telling me that someone found a relationship between two things doesn’t tell me that someone proved the relationship was causal.
But sure, let’s say I accept your (implicit) assertion that this genetic relationship is solid, causal and clear. How does it help solve the problem? It’s a perfect example of research that does nothing except making people feel virtuous for doing the research. Academia is loaded with this stuff, and if you point out that it’s a waste of time and money, you get indignation and faux outrage for having the temerity to “question discovery”.
Y’all keep coming back with “there are always things we don’t know!” as if this is somehow an argument for funding literally any question (and any bad methodology) that someone labels as “science”. It isn’t.
