All of the mistakes are in this paragraph:

> The researchers also claim that harbinger households voluntarily cluster: that when a harbinger household moves, it is likely that it will move to another habringer ZIP code (and nonhabringers move to nonhabringer households). Moreover, harbingers don't appear to learn their preferences from one another — a nonhabringer household that locates in a harbinger ZIP code doesn't alter its purchasing and political contributions to "loser" products and candidates.

> There are multiple uses of Habringer as the spelling

A “Habringer” is someone who brings the “Ha”.

lol, thank you. I will admit my logic for searching for errors was to ctrl-f for "harb" and then see how many matches had "r" vs "i" as the next letter. I never really contemplated that someone would misspell it in that manner.
