alt Hacker NewsI won't argue it's a hacker mindset - it's about learning what matters and what's accidental.
If a article headlines saying "People who wake up early live 20 years longer than people who sleep in", and then it turns out it wasn't the act of waking up early at all, rather, early risers then went out for a run or a swim and people who slept in but did the same actually lived even longer than those early risers, it's important to know that.
Or for one of my favorites, 'a glass of wine a day is healthy' because of antioxidants... or something. Except it isn't, at all. But rather as people's health deteriorates to a sufficient degree they tend to stop drinking (even if not consciously because of their own health), and so when you study light drinkers versus non-drinkers, there was enough of an undetected bias in there to make it seem that drinkers were, on average, healthier. It's easy to see echoes of that possibility in near to any study, especially observational.
