Do Our Senses Reveal the World—Or Do They Obscure It?

April 30, 2017

We know the world exists, we just don’t know what it actually looks like—and it's likely that we never will, says neuroscientist Beau Lotto. Humans can only access reality, whatever it may be, through the filter of our sensory organs, which interpret "inherently meaningless" data in ways that are useful for our survival. We don't see the world as it is, we see the world that helps us to live. It can be a concept that's hard to wrap your mind around: how is that chair not as I see it? What color is an apple, really? Lotto calls on two clarifying examples: "Dressgate", which blew people's minds in 2015 and exposed that perception is not objective, and the color spectrum, of which we only see a small slice of. Beau Lotto is the author of Deviate: The Science of Seeing Differently.
