Cognitive Biases

The Unseen Forces Shaping our Decisions and Behaviors


As a mental health professional, I feel it’s important to bring light to the everyday influences on our thinking that we might not consciously be aware of. These influences, known as cognitive biases, are systematic errors in our thinking that affect the decisions and judgments we make. Often, cognitive biases are a result of our brain’s attempt to simplify information processing. They are not indicative of any cognitive deficits or mental health issues; instead, they’re universal quirks of human cognition.


The Nature of Cognitive Biases

Cognitive biases pervade our everyday life, from the choices we make at the supermarket, to our social interactions, and even our political beliefs. Recognizing these biases can help us understand why we make certain decisions, and also guide us towards making better, more informed decisions.

Let’s delve into some common cognitive biases and how they might be influencing your everyday life:


Confirmation Bias

Confirmation bias is the tendency to search for, interpret, favor, and recall information that confirms or supports our preexisting beliefs or values. For instance, if we believe a particular food is unhealthy, we’re more likely to pay attention to articles and research that support this belief while ignoring those that don’t.

This bias can limit our understanding and acceptance of differing perspectives, fostering misunderstanding, stereotypes, and even hostility.


Availability Heuristic

The availability heuristic is a mental shortcut that relies on immediate examples that come to mind when evaluating a specific topic, concept, method or decision. For example, after seeing news reports about car accidents, you might judge that the risk of being in a car accident is higher than it actually is, causing unnecessary fear or worry.


Anchoring Bias

The anchoring bias refers to our tendency to rely too heavily on the first piece of information we encounter (the “anchor”) when making decisions. This can lead to poor decision-making, particularly in negotiations. For example, if you’re buying a car and the seller sets a high price initially, you may end up negotiating a higher price than if the initial price had been lower, even if the car is not worth the higher price.


Hindsight Bias

Hindsight bias, also known as the “I-knew-it-all-along” effect, is the tendency to believe, after an outcome is known, that we would have foreseen or predicted it. This bias can lead to overconfidence in our predictive abilities and prevent us from learning from our mistakes.


Self-serving Bias

Self-serving bias is the tendency to attribute positive events and outcomes to one’s own character or actions, while attributing negative events to external factors. For example, if you did well on a test, you might attribute it to your intelligence or studying efforts. But if you did poorly, you might blame it on the test being unfairly difficult. This bias can hinder personal growth and limit accountability.


The Impact on Our Lives

The impacts of these cognitive biases are numerous and wide-ranging. They can affect everything from our social relationships, to our financial decisions, our politics, and our mental health. For instance, the confirmation bias can contribute to social polarization, and the availability heuristic can lead to unnecessary anxiety and fear.

Understanding cognitive biases allows us to recognize when our thinking might be skewed and gives us the opportunity to make more informed and balanced decisions. It’s not about eliminating these biases – that’s nearly impossible since they’re deeply ingrained in our cognitive processes. Rather, it’s about acknowledging them and mitigating their impact on our lives.

By gaining knowledge and developing awareness about these biases, we can strive to lead healthier, happier, and more rational lives. We can engage in conversations with a more open mind, make better-informed decisions, and foster stronger and more understanding relationships. Recognizing our cognitive biases is a significant step towards self-improvement and mental wellness.
