New blog post about the age-period-cohort identification problem!
In which, for the first time ever, I ask "What's the mechanism?" and also suggest that sometimes you may actually *not* be interested in causal inference.

One approach to the age-period-cohort problem: Just don’t.
Just to cause yourself more problems, you seek for something. But there is no need for you to seek anything. You have plenty, and you have just enough problems.

Look at the data! It's all over the map.
If you drink half a cup per day, your risk is a little higher than none at all.
If it's 2.5 cups, risk is 20% lower.
But if it's 4.5 cups, risk is only 13% lower.
There's no universe where this makes causal sense.

This is particularly important here, because there’s a huge difference between observational data & trials on artificial sweeteners.
