The universe, ancient Greek tragedies and modern filmmakers all exploit the exact same glitch: the human mind has massive and predictable blind spots.
We easily get distracted, lose track of how we know things, and see patterns in random chaos. This is mainly because our brain hates overworking. To save time and energy, it operates as a full-time prediction machine.
According to neuroscientist Andy Clark’s research, our mind is constantly guessing what’s about to happen next based on our past experiences.
If you see someone walk up to a closed door, your brain predicts they’ll open it. It doesn’t waste energy analyzing every single detail of the doorknob.
As researcher Alireza Modirshanechi and her colleagues noted in a 2023 study, when reality matches your internal script, your brain just sits back and chills.
It conserves resources and updates almost nothing. Because these predictions are usually correct, the brain goes into autopilot most of the time and only pays full attention when something unexpected happens.
“Information we encounter early on influences our estimation of what is possible later. It doesn’t matter whether we’re reading a story or negotiating a salary: Any initial starting point for our reasoning — however arbitrary or apparently irrelevant — ‘anchors’ our analysis,” says Vera Tobin, assistant professor of Cognitive Science, Case Western Reserve University.
So when life throws a curveball, like someone finding out way into adulthood that they were adopted, the brain’s autopilot instantly crashes.
Our vulnerability to surprises and plot twists actually reveals something awesome about our psychology. This non-stop guessing game is a vital survival feature.
Without the ability to make lightning-fast assumptions based on totally incomplete information, we’d experience total analysis paralysis just trying to cross a street.
For example, if someone is completely blindsided by a cheating partner, the immediate instinct is to look back and feel foolish. People blame themselves for missing the signs.
But in reality, the brain was just doing its job.
Unless given a massive reason to expect betrayal, a person’s internal predictive engine defaults to placing a romantic partner into the safe and predictable category.
It’s an evolutionary feature designed to keep people from living in a constant state of paranoia.
So what happens when we experience a plot twist in real life?
First comes the prediction error, the exact moment when facts crash into your expectations.
Research has shown that the anterior cingulate cortex, a region in our brain involved in error detection, plays a key role in processing these mismatches. It helps us update our understanding of what’s happening.
As other areas of the prefrontal cortex integrate the new information, you may experience the mental discomfort of holding conflicting ideas at once, a phenomenon experts call cognitive dissonance.
Once the big reveal drops, we’re left with the curse of knowledge. This is a sneaky cognitive bias that makes it almost impossible to remember what it felt like not to know the truth.
For example, the second we hear the answer to a riddle, it suddenly feels incredibly obvious.
The same thing happens during massive tournament upsets, like a total underdog taking down a legendary champion at the football world cup. The second that final whistle blows, people often think they saw the shock victory coming all along. The brain suddenly hyper-focuses on pre-game red flags it completely ignored an hour earlier.
“What we know trips us up in lots of ways, a general tendency known as the curse of knowledge. For example, when we know the answer to a puzzle, that knowledge makes it harder for us to estimate how difficult that puzzle will be for someone else to solve: We’ll assume it’s easier than it really is,” says Tobin.
This exact sequence plays out in everyday life all the time. Real people are a million times more complex than fictional characters. Real life doesn’t have tidy or scripted conclusions. Humans are full of changing identities and hidden depths that don’t fit neatly into a basic and linear storyline.
Yet, we often form quick first impressions about each other based on incredibly limited data.
