When we are judge and party, it’s easier to come with the scoring scale that put ourself on the top of the board.
If intelligence definition is not imposed on us by nature itself, then we can only conclude that we are indeed great at producing evaluation scales that will flatter our egos. I guess many other animals are also very good at that game though.
If you take "survival of the fittest" (species, not individuals, should I recall?) as the criteria, then we measurably can’t bluster anymore. Many other species survived for far longer than we did, and maybe will outlast us after we finished to disturb so much the environment condition on which our lives depend.
