Amtrak ridership

There exists a peculiar inverse relationship between the number of Americans willing to sit on a train for eight hours and the number of Americans willing to sit on an exercise bike for eight minutes, which suggests either that trains are becoming remarkably comfortable or that we have collectively decided to punish ourselves in increasingly specific ways. One goes up, the other comes down, with the kind of mathematical precision that would normally require causation but here merely requires two datasets and a human brain's bottomless appetite for connection. It is as if the universe is playing a joke at our expense, and we are only now noticing the punchline.

The real culprit, if we're being honest, is probably the economic tide that lifts and sinks all boats simultaneously. Between 2015 and 2022, America experienced a series of lurches—pandemic lockdowns, remote work adoption, shifting consumer spending patterns—that would naturally push people away from both discretionary train travel and the kind of obsessive home fitness that lands you in an emergency room with a torn rotator cuff. Add in the fact that as gyms closed and people bought Pelotons instead, Amtrak ridership cratered, and you have a scenario where a single cultural shift (the great indoor migration) explains both trends perfectly well. It's rather like watching someone's coffee consumption drop and their tea consumption rise, then becoming fascinated by the cosmic significance of the relationship rather than simply noting that they switched beverages.

What we are witnessing here is not causation but two separate datasets dancing to the same invisible orchestra, and our job is to resist the urge to assume the violin is speaking to the drums. The patterns that leap out at us with 91% correlation are often just evidence of a third thing—economic contraction, behavioral change, seasonal variation—quietly conducting both. We see what we're trained to see, which is mostly the shape of our own attention. Spurious correlation, meet actual life.
