What Makes Algorithms Go Awry?

Like it or not, much of what we encounter online is mediated by computer-run algorithms — complex formulas that help determine our Facebook feeds, Netflix recommendations, Spotify playlists or Google ads.

Peru is one of the countries that lays claim to ceviche, which is made of raw fish and chilies, cured in lime juice.
