The previous 100 years have seen a dramatic rise in the relative IQ levels of ordinary people, leading some to ask if newer generations are more gifted. Instead of a true rise in intelligence, however, what we see is a shift based on the demands of a more complex and cognitively demanding world which necessitates the mental habits of clothing the concrete in classification, using logic on abstraction, and taking the hypothetical seriously. The demands requiring this shift include education focused on science (and hence hypothesizing), a higher number of cognitively demanding careers, and an upgrade in the complexity of already existing professions. This shift has unexpected benefits in that using abstraction on universals enables moral debate. In spite of this obvious advantage, ahistorical generations may continue to make the same mistakes as previous generations.
