It's useful to say 'double-blind' rather than 'blind' to forestall confusion - 'double-blind' caters both to people clever enough to realize that blind=double-blind for self-experimenting and also to people not that clever or just not thinking of it.

Yeah, I tend to be conflicted when describing such experiments, for that reason. To most 'double-blind' just sounds like a word for 'scientific' and writing "blind (which incorporates all the rigor inherent in 'double-blind' in as much as both the subject and the experimenter are blind but it isn't "double blind" per se since it is just one dude" is a little verbose. I think I may just go with "self-blinded experiments".
