Let's apply that to this season of The Bachelorette. We know that women care a ton how tall men are. In practical terms, if a Bachelorette has two dozen men to choose from, she will likely pick someone above the average of the group, 6'1" or taller. She weeded out the well-groomed outliers early on; a quick scan of eliminated contestants (red on the chart) find men who stand under 6". Unsurprisingly, all men in the final four meet this criteria.
Looking at the last two successful Bachelorette relationships, both Kaitlyn and Des chose guys who were exactly 10" taller than them. If JoJo, standing 5'4", wants a keeper, we recommend she picks the contestant who comes in at 6'2". This year's prime candidate? Sorry, Chad, who stands at the right height but was way too touchy to go the distance, the guy is Jordan Rodgers.
