Biases

What are Biases?

We all have biases. One view is that biases evolved as part of a human need to make quick decisions for survival. Our brains need to sort through information and make an immediate choice—historically, that choice could be a life-or-death decision. Was that movement in the bushes a friend or a foe? The wrong decision could have dire consequences.

Though times have changed and our circumstances are not always as dramatic as this scenario, our brains are shaped to help us make quick decisions when we perceive that we need to.

Quick decisions can lead to bias. Information from the world around us is often quickly sorted into categories. As humans, we use patterns and make generalizations quickly. It’s involuntary. It’s in our working memory where we track and analyze forming biases.

Though we cannot immediately change this function in our brain, we can work to make ourselves aware of this function and reconsider our initial conclusions. For example, you might meet a person, and they may automatically drop into a category in your mind—you make decisions from that without even realizing it, and those decisions can be and often are wrong.

How Biases and Prejudices Distort Cognitive Processes

At their core, biases and prejudices function as "mental filters" that skew the information your brain receives. Rather than perceiving the world as it truly is, your perspective is shaped by ingrained shortcuts and social conditioning.

This distortion impacts your cognitive processes in several significant ways:

1. Narrowing of Perception

Biases create a tunnel vision effect, causing your brain to seek out information that aligns with your existing beliefs. This phenomenon is known as Confirmation Bias.

  • The Impact: You stop noticing evidence that contradicts your beliefs.

  • The Result: Your world feels smaller, and your ability to learn new, nuanced truths is stifled.

2. Erosion of Critical Thinking

Prejudices often rely on heuristics—mental shortcuts that are useful for simple decisions but problematic for complex human interactions.

  • The Impact: You substitute active analysis with "Automatic Thinking." Instead of evaluating a person or situation on its own merits, you default to a pre-written mental script.

  • The Result: This leads to logical errors and poor judgment, as you react to stereotypes rather than reality.

3. Increased Cognitive Load and Stress

Holding onto deep-seated prejudices is mentally exhausting. Research shows that maintaining a "them vs. us" mindset keeps the brain's fear center (the amygdala) on high alert.

  • The Impact: You experience heightened anxiety or defensiveness when encountering people outside your group.

  • The Result: This "threat response" inhibits the prefrontal cortex, which is responsible for complex problem-solving and empathy.

4. The "Echo Chamber" Effect

Biases not only shape your thoughts but also influence who you listen to, creating a feedback loop where your perspectives are continually reinforced rather than challenged.

Bias Distorts Memory

You "misremember" events to fit your narrative (Selective Memory).

Bias Distorts Empathy

You find it harder to relate to the pain or joy of those outside your group.

Bias Distorts Decision Making

You make choices based on fear or familiarity rather than logic.

Negativity Bias Explained:

The negativity bias refers to a fundamental tendency to notice threats more than we see good things. We are naturally drawn to adverse events more than positive ones. The explanation is that focusing on threats increases the chance of survival. This also causes us to see threats often when they do not exist. Nature wants us to err on the side of caution to help ensure survival. It is better to think there is a tiger in the bush, even if there is no tiger, than not to think there is one when one is there. In the former scenario, you are negative, worried, and anxious; in the latter, you no longer exist.

The negativity bias shifts attention away from healthy, positive experiences toward more exciting, flashy, funny, emotional, or even mean experiences. Social media takes advantage of this by highlighting controversial or emotionally charged information because these companies understand that, ultimately, we pay more attention to adverse events than to positive events.

Students in school overreact, pay more attention to fights, and worry about humiliation because of this bias. If ten things happen during the day, nine are positive, and one is negative, we will likely think more about the one negative than all nine positives together. We might notice that it is a beautiful day outside, yet this bias may encourage negative thoughts, such as wondering how many of these days I have left or thinking about all of the things we must do today.

The negativity bias makes us hypervigilant and makes it difficult to relax and enjoy life. The lower, more powerful part of the brain is programmed to prioritize behaviors that increase our chances of survival. Because of this, we take threats seriously and pay more attention to any adverse events that threaten our survival. This may be perfectly natural and helpful for physical survival, but this bias is powerful and can contribute to maladaptive adjustment problems like sadness and negative ruminations, and it can increase depression and anxiety.

This negativity bias may have been helpful or adaptive a few hundred or thousands of years ago, but times have changed, and threats are very different today. This natural selection toward hypervigilance likely accounts for the higher level of anxiety that many people experience today. We are constantly bombarded with negative, emotional, controversial, and even false information designed to capture our attention and influence our opinions, beliefs, and spending habits.

To balance this bias, we must focus more on the positive things and savor or illuminate small daily positive events by noticing the little things that make life more enjoyable. The idea is to train yourself to notice and hold on to positive daily events and learn to savor small things, take in the good, and allow goodness to sink into your heart and mind. If we briefly notice positive things and let them pass without notice, we tend to regress toward paying more attention to negative events.

The idea is to form positive intentions toward noticing small good things, hold on to good things longer (maintain attention), and allow them to sink in to help you develop more feelings of gratitude and appreciation. This means developing a daily practice of focusing on little things like how good the shower feels in the morning, the first cup of coffee, the drive to work, what may be happening in nature, our pets, our friends, noticing coworkers and loved ones, and actively smiling and saying good morning to everyone. You know, savoring the little things that make your life meaningful if you notice.

. The "Three-to-One" Ratio

Neurobiology suggests that our brains have a negativity bias—we are hardwired to notice threats more than rewards. Research by Dr. Barbara Fredrickson suggests we need a specific ratio to stay resilient.

  • The Practice: For every one negative "automated" thought you have, intentionally identify three small, positive "micro-moments" (e.g., a good cup of coffee, a green light on the way to work, a funny text).

  • The Goal: This isn't about ignoring the bad; it's about training your brain to notice that the good exists simultaneously.

    This also means celebrating small accomplishments by giving yourself kudos when you take even a small step toward a more complex behavior pattern you may be trying to establish. When you notice others or intentionally focus more on positive things in your life, you shift your brain out of the “selfing” mode and into the task-positive mode that exists in the real world, outside your head.

There are several other common biases that can influence thoughts.

Seeking out information confirming existing beliefs and ignoring information contradicting established beliefs.

Selection Bias

When we select or pay more attention to information that will support our desire to see things in a particular way.

Availibity Bias

Confirmation Bias

Overestimation of the likelihood of events based on how easily they come into mind.

Attribution Bias

When we attribute another person’s behavior to a personal characteristic or disposition rather than situational factors, we assume someone did something because they are incompetent, rather than considering the possibility that they are having a bad day.

Anchoring Bias

Relying too heavily on the first piece of information that comes to mind when making decisions.

Situation Bias

When you rule out a situation or location because you feel it is in the “dying end of town.” It takes a person looking at the situation differently to see the area or situation as a place with potential that can be revitalized and turned into a place of growth. Perhaps there are already great folks and stores there that you wouldn’t know about unless you took the time to explore the area.

When we make ourselves aware of these automatic decisions, we can look at the situation at a deeper level, ensure we have thoroughly considered the facts, ask questions, and then make an informed decision.

Have you truly considered the person or the situation as a whole, or did you let your brain categorize something for you as you attempt to move on?

Detecting your biases is the biggest step—your biases come from how you’re made and how you’re raised, but catching them in the moment and questioning them is who you truly are, not those reactions themselves. That’s how you grow.

Common Biases

Bias vs. Prejudice:‍ ‍

Bias is a leaning toward a particular belief or perspective, which may or may not be based on accurate information. It is like the way we are trained. Prejudice refers to a preconceived opinion or attitude about a person or group that is based on incomplete or false information that leads to unfair treatment or discrimination.

So, what can we take away from this section? Biases are a part of who we are and how our brain is set up. They help us interpret and manage all the information coming at us.

We can work to keep biases from hindering our lives by first having self-awareness when biases start settling in. Then, we can take action by questioning our thoughts and asking ourselves if they are true or kind.

Only after we have worked to clear our minds of our biases can we make positive decisions for all!
