And only 3 standard deviations is actually a disability?

• bsder 6y ago
  2SD vs 3SD is a big deal in biological organisms. If we look at height, that's a 6'7"/5'1" male or a 6'1"/4'8" female. At those numbers, the probability that there is a medical issue--malnourishment/endocrine problems/Marfan's syndrome, etc.--starts being non-trivial.
