Reading that felt like a word problem!!!
Put it in another perspective. Take plane crashes for example. And most plane crashes are missing until the wreckage is found. Lets assume that pilots are most likely to own a flight simulator. If we took a random sample from the entire population, there would probably be a correlation between owning a flight simulator and crashing a plane. Because pilots are the most likely to both crash a plane and own a simulator. But if you took the sample from pilots only, the correlation would probably disappear. If more experienced pilots own more sophisticated simulators, you might even get a negative correlation between how advanced the set-up is and likelihood of crashing. That this pilot had an advanced simulator and his plane is missing is a statistical outlier IMO.
