There seems to be higher occurrences of asexuality and celibacy among geniuses than what is typical of most populations. For example, geniuses that were all either asexual or celibate include Fredriech Nietzsche, Issac Newton, Nikola Tesla, Descartes, Immanuel Kant, Michelangelo, Leonardo Da Vinci, Pythagoras, Plato, Aristotle, Spinoza, and more.
I find it unlikely that these men refrained from acting on sexual impulses "in order to sublimate the libido for creative purposes," as some of them may have claimed. Instead, I find it much more likely that many of the traits that are a requirement for genius often lend themselves to an aversion to sex when expressed in high levels.
The first trait that comes to mind for which this may be the case is Conscientiousness. On the Big Five Aspect Scale conscientiousness is comprised of two traits: industriousness and orderliness. People that are very conscientious tend to be vigilant, organized, and sometimes perfectionistic.
Because one needs to have a strong work ethic (and in turn, be conscientiousness) to produce anything of value, one must at times be both very industrious and orderly to be a genius.
People that are very high in orderliness tend to posses a higher than average sensitivity to disgust.
My theory goes as follows: The tendency to produce works of pristine quality requires a high aversion to sloppiness, and that this aversion causes a lower likelihood of engaging in sexual acts when pushed to the extreme levels that are a requirement for genius.
Some readers of this article may note that many of the geniuses that I named may have been autistic, and then claim that it was their autism and not their orderliness that caused them to have non-existent sexual lives. My rebuttal to this reply would be that many autistic people are very orderly and that in the absence of high orderliness one is less likely to be diagnosably autistic, and less likely to experience high levels of sex-related disgust.
