Visualizing 11 cognitive biases that influence how you think

The science of optical illusions

The human brain has developed cognitive shortcuts to help us navigate in a world where our visual senses are constantly bombarded of information. But these shortcuts can also be exploited, tricking the brain into telling us something is happening when it really isn't. This short video unpacks the neuroscience behind some of the most common (but perplexing) optical illusions.

CBT helps rewire the brain's false beliefs by challenging negative thoughts

Cognitive behavioral therapy identifies how specific situations can trigger distorted core beliefs—often formed early in life—that negatively shape thoughts and behavior. It frequently uses structured questioning that promotes self-reflection to uncover distorted thinking and guide people toward more balanced perspectives.

Bias can manifest in algorithmic decisions because the program follows rules that may have been written by individuals unaware of their own biases.

AI tools can reinforce existing societal biases—especially racial ones—because they are trained on human-created data containing implicit and explicit biases.

Because they are built on content produced by humans, who possess biases, generative AI tools inherit prejudices and stereotypes from training data, which later appear in their outputs.

Listen to BlackRock's head of behavioral finance, Emily Haisley, explain the psychology of investing—including controlling biases, managing ego, and being prepared for volatility.

Personality tests, like Myers-Briggs Type Indicator, feel accurate because humans tend to accept generic descriptions of themselves that include flattering statements—a psychological phenomenon known as the Barnum effect.

Apophenia, the cognitive bias that leads people to find meaning in randomness, helps explain why humans look for meaning in their dreams and even in their tea leaves.

Common mistakes we make about the world map

Maps have long loosely approximated what the world actually looks like. Here's a few common errors that persist due to outdated conceptions of the world.

Ranking life's biggest decisions

Psychological research presents some unsurprising wisdom about how to make big decisions without regret: focus on people, don’t miss opportunities, and stay true to yourself.

How metaphors shape the way we think

A metaphor is often viewed as a form of art, deployed only in special circumstances to help an audience grasp something complex or unique. But metaphors are far more fundamental than that, shaping much of how we think about our relationship to others and the world. This article explores how a focus on the metaphors we use can clarify and strengthen our thinking. Learn more here.

How big brands keep your loyalty

We perceive ourselves as rational decision-makers—but research about our consumption habits suggest we are easily played by clever marketing. Here's how big brands design their branding to keep you coming back.

NFL Draft decisions are shaped by brain science, data, and office culture

Carnegie Mellon researchers say Draft-room choices are influenced by the "jackpot effect"—where higher stakes can impair performance—as well as by groupthink, the limits of data, and whether scouts feel safe speaking up.

Addressing psychological barriers to building wealth

Almost half of adults in the US report owning no investable assets. For many, the barrier to entry is the belief that investing is too complex for them to get involved. Consulting with a financial psychologist, this article addresses the cognitive bias that causes so many people to miss out on financial opportunities, and offers tips on how to get past the anxieties and just begin.

The history of brainwashing in America

"Brainwashing" refers to a coerced shift in worldview, often associated with cults or oppressive totalitarian governments. Though such processes are not well understood on a neurological level, they hold an outsized role in public imagination, particularly in science fiction and dystopias. This article reviews the history of the term, first popularized by Edward Hunter in 1950, and the subsequent use of the approach in pop psychology, the CIA, and more.

An interesting perspective on whether (and how) brain size matters in cognitive ability

Some brains are bigger than others, but what is the relevance, if any, to brain size and intelligence? This Scientific American article explores the question and offers examples. It also visually compares frontal slices of several mammals' brains, showing that humans don't necessarily have the biggest cerebrums on the block.

What is the brain up to when the mind wanders?

As you stare into the distance while washing your home's seemingly never-ending pile of dishes, the brain activates its default mode network. This collection of "task-negative" brain regions associated with memory, reward, action consideration, and prediction alight with activity when humans mentally turn inward, possibly giving rise to the brain's ability to wander and humans' ability to construct internal narratives about the world.

The unavailability bias says what we don't see must not exist

Before social media, information was more scarce, and it was the norm not to know much about some controversy or episode. This led to a common prejudice: the availability bias, that what is at hand must be true (in business, the courts, finance, and many fields). With information overload today, the inverse occurs: when something is missing (like the photo of a suspect), it makes us think the suspect does not exist.

The doorway effect is when people forget their task when entering a new space

The "why did I come in here?" feeling after walking into a room comes from the brain creating event boundaries to organize memories. Mentally revisiting a previous room can help recall tasks and reverse memory loss. (Some readers may experience a paywall.)

AI hallucinations are inaccuracies or falsehoods in generated content

AI hallucinations are a by-product of the sequential creation of content based on patterns in text, which may not reflect the context or meaning behind a prompt. Back-end issues like biased datasets and overfitting of model data contribute to hallucinations.

Why your favorite color is probably blue

From a young age, we are primed to choose a favorite color, but strangely as we grow up, our preference often changes—and it’s largely due to influences outside our control.

Browse and explore dozens of major psychology theories

There are a ton of different psych theories—so here's a breakdown of some of the major ones according to the general psychological focus.

There’s a psychological explanation for ‘FOMO,’ or the fear of missing out

This video breaks down FOMO—what it is, how it works, and why it happens—showing how social comparison and uncertainty trigger anxiety that pushes people toward risk-taking and constant checking behaviors.

Nostalgia is a psychological coping mechanism created from bias

Memories are naturally reconstructed during recall, and research has shown a fading effect bias that causes negative ones to fade more quickly, helping us heal. This creates a natural longing for the past, particularly when faced with loneliness, boredom, or challenging moments in the present.

Anthropic's interpretability team discusses how AI models' thinking mimics biology

Just as humans engage in complex behaviors to survive and reproduce, teams of experts in neuroscience, virology, mathematics, and other disciplines argue that large language models develop complex mechanisms to achieve their goals. These mechanisms can be manipulated to assess how they modify outputs—much like stimulating individual neurons—to uncover how LLMs "think."

Two scientists argue consciousness evolved through 'unlimited associative learning,' the ability to learn almost any new pattern during a lifetime.

People are experiencing AI 'brain fry' at work

Workers, particularly in marketing, are experiencing mental fatigue in the workplace due to expectations—often unspoken—that they should use AI to multitask beyond their comfort levels. Many feel they are underperforming if they don't embrace this technology. This situation differs from typical burnout. This podcast discussion suggests that this "brain fry" tends to intensify when employees are required to use more than three AI tools.

Why do some people always get lost?

Using GPS, anthropological data, and VR, scientists have learned that one's sense of direction is largely influenced by upbringing. A person's wayfinding ability can be measured by how accurately they point toward an out-of-sight location, a challenge further complicated by imagining they're somewhere else and pointing toward a third location. Anxiety, safety concerns, and dislike of wandering can negatively impact one's sense of direction, which can improve with practice.

Google Search trends reveal truths about society that traditional surveys miss

Studies of human behavior show that survey respondents may lie to present themselves more favorably. By studying anonymous search data, researchers have uncovered hidden racism, mental health struggles, and interest in taboo or stigmatized topics.

Déjà vu is a memory illusion involving brain regions correcting inaccurate memories

Neuroscientists suggest the phenomenon is your brain recognizing that this feeling of familiarity is incorrect, showing off the brain's internal fact-checking system. Younger people experience déjà vu more often because their brains have higher excitatory activity and stronger memory monitoring systems.

According to Bill Nye, science is under threat from an erosion in critical thinking

He states that conducting research online cannot replace consulting with scientific experts who have spent their entire lives intimately studying a field. The former science education show host argues that deepening cynicism towards scientific institutions has been fueled by leaders embracing debunked and unsupported claims.

Our brains trick us into seeing an enlarged Moon when on the horizon

Humans perceive the sky as a flattened bowl and judge the size of an object by accounting for its perceived distance away from us. Combined, studies have found that the Moon on the horizon is perceived to be larger because the terrain makes it seem like it is farther away, similar to the Ponzo illusion.

A Harvard professor argues that impostor syndrome can be a good sign

Specifically, Arthur C. Brooks has argued that self-doubt is usually evidence of healthy humility—not incompetence—and a clear contrast to the overconfidence of people who actually are impostors in their careers.

How grudges mostly hurt ourselves

Grudges feel like revenge against those who have done us some wrong and are very common. In this "Hidden Brain" podcast, psychologists explain how grudges end up only hurting us rather than those we hold them against. By using historical examples, the researchers show the counterintuitive danger of grudges and how people can learn how to avoid them.

How your subconscious influences your decisions

How much of your desires and daily choices are truly yours? One of the most effective ways to influence someone's subconscious is when they're asleep. To study this possibility, researchers trained participants to be able to dream lucidly, a phenomenon that occurs when a dreamer knows they're dreaming.

Why patterns in art are so pleasing

Repeated visual cues like shapes or lines derive from the brain's innate compulsion to identify faces, places, bodies, and more. With repeated shapes, the brain seeks out resolution to the subtle variations between them. See examples in art and music.

Negative thinking spirals are often the result of uncertainty and anxiety, and can be addressed.

The myth of multitasking's prestige

In this article, renowned neurologist Richard Cytowic seeks to expose multitasking as a fool’s errand. Cytowic explains how the brain, like a computer, switches between tasks rather than handling multiple tasks at once. He shares that attempting to focus on multiple activities at the same time consequentially decreases the brain's ability to ignore distractions, maintain focus, and organize information. Instead, he suggests, try to focus on completing one thing at a time.

The dreaming brain, as understood by scientists

Technology has advanced to where the seemingly separate fields of psychology and neuroscience are asking the same questions about dreams, such as whether they're more closely related to perception or visualization. Some field-intersecting findings include research that shows people with impaired face perception don't dream of faces, those with brain legion-related cognition difficulties deal with similar issues in dreams, and children's dreams change in parallel to their cognitive development.

Four psychological tools for a happier, calmer life

The perennial debate on how to be happy involves various aspects of life, and one of the most essential is our psychological attitudes toward experiences. This piece lists and explains four basic tools to strengthen your "psychological immune...

Neural implants blur the line between personal intention and machine execution

A key ethical dilemma—the contemplation conundrum—explores whether implants might misinterpret mere imagination as intent to act. Neuroscientists have found no brain signal that clearly marks when someone decides to act, making intent hard to detect in neurotechnological systems.

Bill Nye made a course on the framework of scientific thinking and problem solving

The class focuses on developing and fostering critical thinking skills to evaluate the world and the accuracy of claims. Nye highlights how these skills can be applied to overcoming fear of the unknown and engineering creative, outside-the-box solutions to some of the world's biggest challenges, including climate change.

How does the cocktail party effect work?

In the 1950s, British cognitive scientist Colin Cherry started to explore how we could focus our hearing on one single source, even in a noisy environment. This video animation explains the phenomenon known as the cocktail effect and how selective hearing works. Discover how our brain is on the lookout for important or personally relevant information, even as we are occupied in other discussions.

How science explains déjà vu

Take a fun look at the science explaining the odd experience of déjà vu, which some theories suggest is actually a sign of a healthy brain.

Psychology research shows that conspiracy theorists tend to have a desire to be unique

While conspiracy theorists are often understood to have feelings of powerlessness in their lives, research suggests they may also be inclined to set themselves apart from the masses.

Research suggests using AI for schoolwork may harm critical thinking skills

An MIT study finds lower brain engagement in students who used ChatGPT, resulting in consistent underperformance in neural, linguistic and behavioral levels. AI users struggled to recall their own essays, while the brain-only group showed the highest neural connectivity and satisfaction.

How to build curiosity

Change and uncertainty induce stress, but reframing the unknown into an opportunity for discovery has tangible benefits. Approaching change with curiosity enhances activity in the hippocampus and promotes neuroplasticity, promoting learning and serving as a barrier against anxiety. A neuroscientist explains how embracing the unknown, trying small experiments, and other techniques build curiosity.

False memories can form during recall when new information is incorporated

Often formed due to suggestion and misinformation, false memories can lead to serious consequences, such as wrongful convictions. The time between an event and recalling it affects one's susceptibility to false memories.

Researchers use the brain's ability to edit memories to explore memory deletion

Scientists have successfully implanted false memories in mice after studying how the editing process works in the brain. Beyond potentially deleting memories in those with PTSD, upcoming research may allow clinicians to forecast the onset of neurodegenerative diseases.
