The story of our reality

Interesting article on how what we perceive isn’t always the reality. We make up stories that shape our perceptions.

“‘It’s really important to understand we’re not seeing reality,’ says neuroscientist Patrick Cavanagh, a research professor at Dartmouth College and a senior fellow at Glendon College in Canada. ‘We’re seeing a story that’s being created for us.’ Most of the time, the story our brains generate matches the real, physical world — but not always. Our brains also unconsciously bend our perception of reality to meet our desires or expectations. And they fill in gaps using our past experiences.”

“Why are we seeing a story about the world — a story — and not the real deal? It’s not because evolution made our minds flawed. It’s actually an adaptation.”

“‘The dirty little secret about sensory systems is that they’re slow, they’re lagged, they’re not about what’s happening right now but what’s happening 50 milliseconds ago, or, in the case for vision, hundreds of milliseconds ago.’ If we relied solely on this outdated information, though, we wouldn’t be able to hit baseballs with bats, or swat annoying flies away from our faces. We’d be less coordinated, and possibly get hurt more often.So the brain predicts the path of motion before it happens. It tells us a story about where the object is heading, and this story becomes our reality.

“What we experience as consciousness is primarily the prediction, not the real-time feed. The actual sensory information, he explains, just serves as error correction. ‘If you were always using sensory information, errors would accumulate in ways that would lead to quite catastrophic effects on your motor control,’ Hantman says. Our brains like to predict as much as possible, then use our senses to course-correct when the predictions go wrong. This is true not only for our perception of motion but also for so much of our conscious experience.”

“The big principles that underlie how our brains process what we see also underlie most of our thinking. Illusions are ‘the basis of superstition, the basis of magical thinking,’ Martinez-Conde says. ‘It’s the basis for a lot of erroneous beliefs. We’re very uncomfortable with uncertainty. The ambiguity is going to be resolved one way or another, and sometimes in a way that does not match reality.’ Just as we can look at an image and see things that aren’t really there, we can look out into the world with skewed perceptions of reality. Political scientists and psychologists have long documented how political partisans perceive the facts of current events differently depending on their political beliefs. The illusions and political thinking don’t involve the same brain processes, but they follow the similar overarching way the brain works.”

Great article. I encourage reading the entire original to see the many examples of how our senses deceive us.
