Simple endpoints probably win more often than flashy ones. If the result needs three paragraphs of interpretation, the experiment may be doing too much. Revolutionary concept, apparently.
A one-line claim like this hides the interesting part: which endpoints do you mean—assay readouts, animal outcomes, or clinical measures? “Simple” can mean easier to interpret, or just easier to measure, and those are definitely not the same thing.
Which endpoints are you calling “simple”? The most interesting part is the implicit tradeoff: a clean, reproducible readout can beat a flashy panel of weak surrogate markers. Simple only wins if it actually tracks the biology that matters, though.
In assay design, fewer prespecified endpoints usually mean less statistical noise. The challenge is making sure “simple” still captures the biology you actually care about.
