 When confronted with the Repugnant Conclusion, many share the view that the conclusion is highly counterintuitive. However, it has been suggested that it is premature to conclude from this that the conclusion is morally unacceptable. Two sorts of reasons can be given in favor of the view that the conclusion should be accepted. According to the first, while it is correct that the conclusion is counterintuitive, there are nevertheless certain theoretical considerations outweighing this intuition to such an extent that we should accept it. The claim that no plausible theory can avoid the Repugnant Conclusion or that the rejection of the conclusion would force one into rejecting claims which it is hard to get around—e.g. such as the premises of the Mere Addition Paradox—may constitute such considerations (Tännsjö 2002; Holtug 2004; Huemer 2008). According to the second, the source of the unacceptability of the conclusion is the fact that we are deluded by our intuition (Sikora 1978, 2004; Mackie 1985; Tännsjö 1992, 1998, 2002; Hare 1993; Ryberg 1996a, 2004). Once we fully understand what the conclusion amounts to, we will cease to find it counterintuitive. For instance, it might be suggested that the repugnance, at least partly, is due to our limited apprehension of large numbers (Tännsjö 2002; Broome 2004). We cannot imagine what it would be like for there to exist billions upon billions of people, and hence our intuition is not based on a sound picture of the moral significance of population Z (for a critical discussion of these kind of arguments, see Temkin 2012 and Pummer 2013). Moreover, several theorists have suggested that our intuition is misguided by a misapprehension of what it is like to lead a life in Z, i.e., a life that is barely worth living. The idea is that once we realize that such a life is not terrible but perhaps a life not much different from a normal privileged one, the conclusion loses its sting (Mackie 1985; Tännsjö 1992; Ryberg 1996a). Thus, on both views, though population ethics may constitute a complicated area of ethical research, it is at least devoid of what is traditionally regarded as one of the cardinal challenges.
