The bell curve distribution for IQ scores tells us that two thirds of the world’s population has an IQ somewhere between 85 and 115. This means that some four and a half billion people around the globe share just 31 numerical values (“he’s a 94,” “you’re a 110,” “I’m a 103”), equivalent to 150 million people worldwide sharing the same IQ score. This sounds a lot to me like astrology, which lumps everyone into one of 12 signs of the zodiac.
Learn to Think Better: Tips from a Savant: Scientific American (via Sullivan and others) I genuinely love that attempts to quantify humans in some scientific manner—Meyers-Briggs, IQ, light cones, percentile growth, philosophical adherence, demographics, socioeconomic background, etc.—seems to break down into a groupings that lie too closely to astrology for our own comfort. Such a great quote.
