And yet the CIE 1931 Standard Observer still seems to be the best
statistically-based "educated guess" available so far of human spectral
responses, which, due to the fact that each individual is slightly or even
markedly different from the rest, would otherwise be either unknowable or
would have to be studied person by person -- a clearly impractical
proposition.
