Answered on Quora.
Do you mean Genius as a metric on the IQ scale?
If you have an IQ of 140+, you have a Genius IQ on the IQ scale. “Genius” is just a word for a metric on the scale.
71–79 - Retarded/Intellectually impaired 71–79 - Borderline/Dull 81–89 - Low Normal 91–109 - Normal 110–119 - High Normal 120–129 - Bright 130–139 - Gifted 140+ - Genius
Keep in mind that on this scale, geniuses are almost as common as weeds. 1/100 has a genius IQ. There are 3.3 million Americans with genius IQ’s.
Or do you mean genius in the way we use as someone with a truly great and exceptional mind?
It is hard to say, but if you are so damn smart or talented that your friends or even strangers start saying you’re a genius, then maybe you are one. This is not a label that one calls oneself. It is a label that is determined by the opinions of others. If people you know are calling you a genius, you deserve to be damn proud of yourself.
