I realize a major goal of most advertising isn’t to make you think too hard about the product or service being advertised, it’s just to make you feel happy thoughts and buy stuff.
However, it is fun once in a while to take a second and think about some of the information being presented. My personal favorites are car insurance ads that mention the fact that “Drivers who switch to XYZ insurance save an average of $8,483,179 (or something like that)”. Seems like it would pretty easy to come up with stats like that when you limit the set of data to “drivers who switched”.
Someday I want to find a bunch of people who would end up paying more according to Geico’s formulas and get them to switch just to mess with their averages.
