Table 6: Possible impacts from genetic selection in different scenarios. The first scenario is "IVF+, or selection of 1 of 2 embryos." Bostrom writes that if this gets 90% adoption, then "Learning disability much less frequent ... in second generation population of above high IQ thresholds more than doubled." In the next scenario, "Aggressive IVF, or selection of 1 of 10 embryos," the result of 90% adoption is "substatial growth in educational attainment, income." The third scenario is "In vitro egg, or selection of 1 of 100 embryos," the result of 90% adoption is "raw IQs for eminent scientists 10+ as common in 1st generation. Thousands of times in 2nd generation." The final scenario, "iterated embryo selection," involves selecting desirable genetic traits from embryos, converting them into sperm/ova, then creating a new embryo, extracting desirable genetic traits, and so forth, until you've created a super embryo. Bostrom writes that even if only .25% of the population does this, we might have an "intellectual renaissance." If there's 90% adoption, we have "posthumanity."
