On "Bad" Gossip

This sort of thing happens all the time. If we get information about people from third parties – gossip – we start paying more attention to those people. There’s a simple reason for this. Gossip, especially negative gossip, affects not only our judgment, but our vision too. It influences both what we think about someone and whether we see them in the first place.

Eric Anderson and Erika Siegel from Northeastern University studied the influence of gossip on our vision with a simple experiment, which plays off a well-known conflict between our eyes. When each eye sees a different image (say, if they stare down different tubes), those images compete with one another for dominance. This is called “binocular rivalry”, and the brain acts as the arbitrator. It chooses to consciously experience one image and suppress the other. The result: even though your eyes sense both images, you only “see” one of them.

The duo sum it up best: “Hearing that a person stole, lied, or cheated makes it more likely that a perceiver will consciously see that structurally neutral but purportedly villainous face.” When given a choice, our brains prioritise those faces for conscious attention.
This is an important idea, and worth repeating: what we “see” isn’t simply dictated by the signals that travel from our eyes to our brain. Our brain processes these signals by smoothing out inconsistencies and focusing our attention on important details. This is why we don’t see a gaping dark hole where our blind spot is. It’s why the world doesn’t periodically go dark whenever we blink. It’s why when you burn your hand, the feeling of pain and the sight of your recoiling limb seem simultaneous, even though the xxxx reaches your brain first.
And it’s why a negative statement can make a face stand out more than a positive one. Our brain offers up a view of reality that allows us to get on with our lives, but that’s always somewhat of an illusion.
