don't many confounders, confound the relationships? That is if there is enough confounders with overlapping effects, doesn't this break the statistics?

I didn't know randomization breaks confounders. I'm skeptical of that... how do we know the samples themselves are good enough? I guess it's "unlikely" to get a sample that isn't good enough.

I'd feel more comfortable first prooortionately stratifying samples, and then randomly sampling them while holding the stratification sizes proportional to get a proportionately allocated stratified simple random sample.

I also don't see the difference between statistical controls applied to simple random samples and experimental trials. They seem to be logically equivalent.

Do you have seasonal allergies? Consider consuming more vitamin C if you haven't already. It is a natural anti-histamine.
