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.

Realistically yes, science and academia are loaded with "waste". The vast majority of questions there's nothing interesting or useful to discover. The problem is that we don't know ex ante which questions fall into that category (except you, obviously, you do know this, but just don't want to share the secret sauce)

And no I think people are coming back with "there are things we don't know that seem highly relevant to understanding and improving our population's wellbeing." The two ingredients to fixing a problem are knowledge and action and it's not scientists' jobs to be doing the action part, and while one could argue we have all the knowledge we need, a reasonable counterargument is that the only way we know we have the knowledge we need is when action is taken (and successful). And we're obviously not there yet.
