This is a really well-articulated explanation for the phenomena that have clumsily attempted to describe before. As someone interested in cars, I use the example of Cadillacs and Buicks most frequently, since they used to be symbols of power, prestige, and quality but seem to sell almost exclusively to people over the age of 60 today. I actually always play a game when on the highway: I check the drivers of Cadillacs and Buicks and my anecdotal sample has been heavily skewed towards older owners.

I wish that the mesofacts site was more complete, because I love updating my firmware. While reading it, I kept thinking "What else is it there I don't know I don't know?"
