The classic from which all this comes is the UK bus system. You had the driver and the conductor. Equivalent jobs, from an equivalent background, with equivalent lifestyles away from work. But drivers sat and the conductors stood. Very, very different outcomes.
This is literally the example from which we learned that standing and walking around helps prevent heart attacks.
- Noumenon72 2y agoThose jobs seem about as equivalent as driver and passenger. You have to focus and avoid risks all day long as a driver. I'm suprised conductor pays more. I imagine they attract different types of people as well -- customer service people vs video game people. Must have been tough epidemiology to tease a signal out of that.
- HPsquared 2y agoThey probably just ignore all the confounding variables and focus on what can be measured.
- btilly 2y agoWhat makes you think that conductor paid more? Certainly nothing that I said! Likewise what makes you think that the epidemiology was hard? The statistics were absolutely brutally obvious. The main problem was getting people to look at the data, not interpreting it. See https://bcmj.org/articles/exercise-and-heart-review-early-studies-memory-dr-rs-paffenbarger https://bcmj.org/articles/exercise-and-heart-review-early-st... for some of the early history that is involved here.
