Hard data is difficult to come by as those who have never existed failed to respond to a survey even after repeated phone calls and mailings.
As a proxy population we instead investigated a population of hypothetical individuals: those who if they had existed would respond to a survey. This population broke down into two subpopulations — those who if they existed would say it is better to exist than not, and those who said the opposite. Extremely robust results supported the conclusion that
i)those who if they had existed would have preferred to exist prefer to exist
ii)those who had they not existed would not have have preferred to exist prefer not to exist.
Although the impact of this data on the policy issue of serving the underserved population of those who do not exist deserves further study a preliminary result that suggests itself is to divert resources from those who if they did exist wouldn’t like it to those who if they did exist would like it a lot. For this underserved population of non-existing people an immediate emergency measure would be to bring them into existence; either by sexual intercourse or carving them out of wood or whale blubber.
