 It does not seem that any of these four tests of self-other merging provide a reason to believe that the participant views herself as numerically identical with another person. Indeed, both the perceived similarity test and the personal attribute rating test seem to be assessing qualitative identity rather than numerical identity.  And it is far from clear what, if anything, the other two tests are measuring. So it seems that there is really no evidence at all that people in close relationships lose track of the distinction between themselves and another person. Indeed, as May notes, if someone really did believe that he exists in two obviously distinct bodies, the most natural conclusion to draw would be that he is delusional (May 2011b: 32).
