Yes, I do think there's a way to identify them. There is currently research being done into that. (Although you seem to think it's pointless because it's impossible) However, me thinking that it is possible to identify them does not mean that I think it is possible to take an existing population study and somehow 'change' it so that information about susceptible individuals can be extracted from it.
