Asifa Majid, a cognitive scientist at Oxford, presented Michael Rosen, the host of a podcast on language, with little containers that looked like yogurt cups. He could smell — but couldn’t see — what was inside.
Correctly identifying the coffee was easy. But when Rosen mistook a cinnamon bun for a blueberry muffin, Professor Majid said he’d made a common mistake.
But what kind of mistake is that? And how do we make it?
I wouldn’t describe it as a physiological mistake. (The sensors in Rosen’s nose seemed to be working.) But I wouldn’t describe it as a mental mistake either. It’s not what anyone I know would call a logical error — which might suggest that I have a defective sense of what logic should be.
One clue to this muddle is that Rosen determined he’d made a smelling mistake by looking inside the cup and seeing a cinnamon bun. (Roy Bedichek called the sense of sight the despot of the senses.)
Mistakes are helpful in clearing up our thinking. But when we can’t even grasp what kind of mistake we’ve encountered, we’ve usually run across a conceptual problem.
I think this one is a relative of the mind-body problem. No matter how often I bury the ancient distinction between mind and body and their realms of mental and physical phenomena, I find that it’s still finding new ways of confounding me.
Our perceptions don’t fall neatly into either category.
