As people of IQ less than 200, it’s difficult for us to imagine how a society might look if our species were magnitudes more intelligent than we are today.

In the early part of the 20th century, there was a reluctance to talk about either the subconscious or the unconscious.

Blog / By

Each of us has an internal perception of success that is based upon the environment in which we live and the “tribes” to which we belong.

Who had a higher IQ than Einstein? Why did this person not gain the same level of fame as Einstein for their work in physics and mathematics?

Although Einstein never sat for an IQ test, he probably would have scored very high, but not as high as some, because his kind of intelligence is not captured in a series of 45-minute IQ tests. While IQ tests provide a good measure of certain cognitive skills, they do not measure the long-term problem solving …
