Somebody anonymous said:

it was about silly people who mutter things under their breath while leaving that they don't want to subject to criticism.

Oh, give me a break. I never said that I didn't want people to subject it to criticism. To do so would be pathetically easy, seeing as it's a barely remembered anecdote. I said that I didn't want to take part in the argument (which would require doing quite a lot of research to present a proper case, and I'm afraid I just don't have the time right now). I only added the comment because I thought it was vaguely interesting, that there might be other people here who knew more about that sort of thing and who might make their own interesting comments, and because, if nothing else, it might get people thinking about possible experiments that could further investigate meta-cognition (or it's absence) in other animals.

If you'd like to criticise it, go right ahead.
