I might be totally mistaken here, but the calculation done by Donald Hobson and Paul seems to assume von Neumann’s genes are sampled randomly from a population with mean IQ 100. But given that von Neumann is Jewish (and possibly came from a family of particularly smart Hungarian Jews; I haven’t looked into this), we should be assuming that the genetic component is sampled from a distribution with higher mean IQ. Using breeder’s equation with a higher family mean IQ gives a more optimistic estimate for the clones’ IQ.
