I feel like this example really gets at what I like about reading Andrew Gelman's blog. Re-weighing yourself 46 times because your bathroom scale is high variance is such an obviously unreasonable thing to do that almost no one would do it, but it's a great example of the kind of process I love to see:

I now started to wonder if the spring bathroom scales exhibit some sort of drift when you step on and off them multiple times in quick succession (e.g. due to heating).
