Stephen S Posted over 1 year ago Alex Wissner-Gross: A new equation for intelligence When an animal picks up a stick and uses it as a tool, we would generally agree it is a sign of intelligence. But in doing so, the animal is not motivated by a desire to maximize future options, but rather to solve a problem. It seems to me that the more fundamental hallmark of intelligence is problem solving. A second failing of Wissner-Gross' theory is that according to his criterion for intelligence, politicians must be surely the most intelligent people in the US, given their penchant for keeping their options open. Political preferences aside, can anyone seriously accept that on face value?
