Ya know, technically,...
"Nutrition research tends to be unreliable because nearly all of it is based on observational studies, which are imprecise, have no controls, and don’t follow an experimental method."
You could say the same things about astronomy.
- beiller 5y agoYa if astronomy was done by taking photos of the sky 30 years ago, erasing them, and only using their verbal descriptions after 30 years to draw a hypothesis.
- jessaustin 5y agoIn 1695 Edmond Halley predicted the return of his comet in 1758. That was one of the first astronomical experiments, but it was hardly the last.
- DubiousPusher 5y agoBut observation is the point of most astronomy. Determining causatiom is usually not the goal. Observing people's weight over time is ome of the reliable and useful things nutritiom research has accomplished. But the goal of the kind of research being discussed here though is to study causation.
