“The brand most predictive of top income in 1992 is Grey Poupon Dijon mustard. By 2004, the brand most indicative of the rich is Land O’Lakes butter, followed by Kikkoman soy sauce. By the end of the sample, ownership of Apple products (iPhone and iPad) tops the list. Knowing whether someone owns an iPad in 2016 allows us to guess correctly whether the person is in the top or bottom income quartile 69 percent of the time. Across all years in our data, no individual brand is as predictive of being high-income as owning an Apple iPhone in 2016.”
OK, Grey Poupon mustard isn’t fancy at all. The one I buy is at least twice the price. We only buy Land O’Lakes butter because N has some weird attachment to it. We have no tablets in the house and nobody has an iPhone. I hate the brand and find it deeply deficient. My sister showed me her iPhone today, and it has no opening for headphones even. It’s total crap.
This test sucks.
