I see it more as a survival trait for a population, not an individual. An individual does not need to procreate for a population to benefit from any trait they may have. In that sense, the trait may be a disadvantage for the individual, but increase the well-being of the population at large. An unimaginative example would be an autistic individual whose condition enables them to make a life-saving scientific or mathematical breakthrough, but due to the same condition ultimately dies alone and childless.
