From Heightism to Megalomania

Being tall is great. Height is incredibly important. Tall people appear competent, earn more money, and occupy privileged positions in society. Those who can look down on others not only appear dominant to those around them, but, to make matters worse, are also convinced of their own greatness. These and similar prejudices do not exist by chance: they have evolutionary roots. Body size is a signal. Its regulation has been conserved in the vertebrate lineage for at least 400 million years and because this signal is also used by humans quite naturally and strategically, it eludes our conscious perception almost entirely.
