They should have done a crossover trial, where group A is a random selection of archers initially getting no C bows, and then later getting them, and vice versa for group B. Paired t-tests, y’all!

Yeah, but the meme is a joke about how you can prove anything with regression to the mean. If all archers are equally good and we test them we would get varying results. If we then split them on performance and perform an intervention and test again then the “poor performing” group will do much better. Because it’s just random noise.
