This may seem like an odd question but what do you think a "Genuis" would look like?
A genius can look like anyone, because what makes someone a genius is inside the head. There are pictures of MENSA members, and you can see examples. Geena Davis is technically one. There was a little girl just deemed a genius. Ronan Farrow was a savant and genius. There are a lot of geniuses who have difficulty functioning in society, so high intelligence does not mean an easy road.
Having an adaptive above-average mind probably is more useful that excess intelligence for the daily functioning.
A genius does not necessarily look like anything out of the ordinary. Where the difference is seen is in the work done by them.
Hi IQ is speed. A person who processes faster will accumulate more knowledge than a normal person of the same age. Ask a question not generally known. A genius will probably know the answer.
@TimTuolomne Speed and capacity for the ability to process prodigious amounts of information. Absolutely agree.
@TimTuolomne a smart person would usually not try to answer stupid questions.
