It was approximately 100 years ago when specialists – mainly psychologists – started researching human intelligence using the IQ – intelligence quotient. There are many definitions (or understanding) of intelligence – from the ability to adjust to a statement that intelligence is an entire set of factors related to the speed of thinking.

My own, simplified definition of intelligence is: Intelligence is the ability to arrive at a true (correct) conclusion (result) from certain presumptions (facts). I define geniality as the ability to conclude correct conclusions also from an insufficient amount of facts.

That's a good definition! Sometimes I think we use our sub-conscience to arrive at a conclusion, with the result that it is very hard to substantiate in an academic way, where only substantiated information is considered as in science. I believe human progress in the sciences would have progressed at a much faster pace had they been more open to hypotheses. Does that make sense to you?
