dildo might be more apropos
But a dildo has its own solidity, so if you wanted to criticize someone for having no original content, condom would be the better analog. It gets into an intermediary position, collects substance from one, but fails to transmit the substance, just passing along the feeling.
But I'm just helping you out in your description, because I didn't feel that way about the interviewee. What I'd like to know is whether he ever got back to the 3 other categories of mind control after Bell stopped him at #1. I fell asleep about halfway thru.
Doing that sort of thing is something I fault Art for. Sometimes you need to exercise restraint over eagerness. Someone wants to lay out 4 categories quickly, you let hir do so. Then you can ask about whichever ones you're interested in. Noory couldn't do that, because by the time he'd get to #4, he'd've forgotten #1, but Art can. Sometimes he lets his enthusiasm carry him away too much.
