Cognitive Biases: How Your Brain Shapes the Way You See the World
Have you ever been convinced someone was upset with you, only to find out later that nothing was wrong? Or had one bad day at work and suddenly felt like every aspect of your job was terrible? Moments like these are a good reminder that the way we experience a situation is not always the same as the full reality of it.
A cognitive bias is a predictable tendency in how we think, interpret information, remember experiences, and make decisions. Cognitive biases can influence how we see ourselves and how we understand other people. They can also deeply impact how we respond to situations in our everyday lives.
Recognizing cognitive biases is important because our thoughts do not always give us a completely objective picture of what is happening. We may feel certain that our interpretation of a situation is accurate while our brain is actually filtering information through familiar assumptions, emotions, past experiences, or mental shortcuts.
Importantly, cognitive biases are not signs that something is wrong with us. They are a normal part of how the human brain works. We are constantly taking in enormous amounts of information, and our brains need efficient ways to sort through it. These shortcuts allow us to make quick decisions without carefully analyzing every piece of information we encounter. While this is often useful, it also means our brains can sometimes leave out important information or place too much importance on certain details.
Here are a few common cognitive biases you may recognize in everyday life.
Attentional Bias
Attentional bias occurs when our attention becomes disproportionately focused on certain types of information while overlooking others.
For example, someone struggling with social anxiety may walk into a room and immediately notice the one person who appears uninterested while barely registering several people who smiled or welcomed them. Our brains are particularly good at noticing information that feels relevant to potential threats, which historically helped humans stay safe. Unfortunately, this can also reinforce anxiety, insecurity, and negative beliefs about ourselves.
Confirmation Bias
Confirmation bias is our tendency to notice, remember, and give more weight to information that supports beliefs we already hold.
If someone believes, “I’m not good at my job,” they may dwell on one piece of constructive feedback while minimizing ten positive comments from colleagues. In relationships, someone who fears their partner is losing interest may closely monitor delayed texts while overlooking consistent signs of care and commitment.
Confirmation bias helps the brain maintain a consistent understanding of the world, but it can also strengthen beliefs that may not tell the whole story.
Fundamental Attribution Error
The fundamental attribution error describes our tendency to explain other people’s behaviour through their personality while explaining our own behaviour through circumstances.
If someone cuts us off in traffic, we might think, “What a selfish person.” If we accidentally cut someone off, however, we may think, “I didn’t see them. I’m exhausted.”
This bias can contribute to conflict in relationships and workplaces because we may assume that another person’s behaviour reflects who they are rather than considering what might be happening around them.
Hyperbolic Discounting
Hyperbolic discounting refers to our tendency to prioritize smaller, immediate rewards over larger rewards that come later.
It is why scrolling on our phone can feel more appealing than starting a project, ordering takeout can win out over cooking, or avoiding an uncomfortable conversation can feel easier than addressing an issue that could improve a relationship long-term.
Our brains naturally place greater value on rewards we can access immediately, which can sometimes make long-term goals difficult to prioritize.
Recency Bias
Recency bias means giving greater importance to information or experiences that happened recently.
After one difficult week at work, for example, we may suddenly feel as though we have always hated our job. After an argument with a partner, it can temporarily become harder to remember the closeness and positive experiences that came before it.
Recent experiences are easier for the brain to access, so they can sometimes feel more representative of the bigger picture than they actually are.
Sunk Cost Fallacy
The sunk cost fallacy occurs when we continue investing in something primarily because of what we have already invested.
Someone might stay in an unhappy relationship because “we’ve been together for eight years,” continue pursuing a career they dislike because of years spent training for it, or keep pouring money into a project because they have already spent so much.
Letting go can feel as though our previous time or effort was wasted, even when continuing may ultimately cost us more.
There are many more cognitive biases beyond these examples, and we are all influenced by them. Becoming aware of cognitive biases is not about second-guessing every thought or trying to become perfectly rational. It is about developing a little more flexibility in the way we interpret our experiences.
Sometimes the most helpful question is simply, “Is there another way I could understand this?”
Learning about cognitive biases is not about catching ourselves thinking “wrong”. It is about becoming a little more curious about our minds and a little less certain that our first interpretation is the only one. Ultimately, it allows us to be a little more compassionate with ourselves and others as we learn to see situations from wider perspectives.
