If you're not very smart yourself, how could you possibly know you've never met anyone dumber than you? My point is that the "dumb-smart"-axis is largely subjective and quite useless for putting a person on. Doesn't matter what you call it. IQ tests have a long history of being biased. There's not even a consensus on what intelligence is exactly. Trying to score it using a single number is just ridiculous.
