Ah, snap judgments. While they have been known to get you in trouble from time to time (What? That bazillionaire techie so looked like a homeless person…), on the whole they tend to be accurate.
See how good your appraisal skills are by playing Judgey, a totally fun and time-wasting online game that has you guessing how good books are, based entirely on their covers. Give each jacket a rating, and then see how close you got to its actual GoodReads average.
