Intelligence in general or Universal Intelligence is the ability to efficiently achieve goals in a wide range of domains. This tag is specifically for discussing intelligence in general or human intelligence in the broad sense.
For discussion of IQ testing and psychometric intelligence, see IQ / g-factor; for discussion about e.g. specific results in artificial intelligence, see AI. These are distinct tags but may overlap with this tag to the extent that they discuss the nature of general intelligence.
Examples of posts that fall under this tag include The Power of Intelligence, Measuring Optimization Power, Adaption-Executers not Fitness Maximizers, Distinctions in Types of Thought, The Octopus, the Dolphin and Us: a Great Filter tale.
On the difference between psychometric intelligence (IQ) and general intelligence:
But the word “intelligence” commonly evokes pictures of the starving professor with an IQ of 160 and the billionaire CEO with an IQ of merely 120. Indeed there are differences of individual ability apart from “book smarts” which contribute to relative success in the human world: enthusiasm, social skills, education, musical talent, rationality. Note that each factor I listed is cognitive. Social skills reside in the brain, not the liver. And jokes aside, you will not find many CEOs, nor yet professors of academia, who are chimpanzees. You will not find many acclaimed rationalists, nor artists, nor poets, nor leaders, nor engineers, nor skilled networkers, nor martial artists, nor musical composers who are mice. Intelligence is the foundation of human power, the strength that fuels our other arts.
