Confirmation Bias

Confirmation bias is our tendency to search for, interpret, and remember information that confirms our pre-existing beliefs. For example, if you believe that exercise is essential for mental health, you'll likely give more weight to articles supporting that view and dismiss those that don’t. This bias can lead to serious misjudgments as it blinds you to alternative perspectives.

Anchoring Bias

Anchoring bias occurs when we rely too heavily on the first piece of information encountered (the “anchor”). For instance, if you see a car advertised for $30,000 and then find another for $25,000, you might consider the second car a good deal, even if its actual value is much lower. This bias can lead to skewed decision-making.

Overconfidence Bias

Overconfidence in your knowledge and judgments can seriously distort your decisions. For example, investors often overestimate their expertise, leading them to take unnecessary risks. Recognizing that everyone has limitations can help you navigate this bias more effectively.

Availability Heuristic

This bias involves making decisions based on immediate examples that come to mind. For instance, after seeing news reports about airplane crashes, you might overestimate the risk of flying. To counteract this, look at real data rather than media portrayals.

Bandwagon Effect

The bandwagon effect is our tendency to do or believe things because many others do. Peer pressure in high school is a classic example. To combat this, question whether the group's decision truly aligns with your personal values and evidence.

Hindsight Bias

This bias makes past events seem more predictable than they were. After a stock market crash, people often say, “I knew it all along,” despite having no evidence beforehand. Understanding that outcomes are often uncertain can temper this bias.

Self-Serving Bias

Self-serving bias involves attributing positive events to our character and negative ones to external factors. For example, if you do well in a job interview, you might credit your skills; if not, you blame the interviewer's bias. Recognizing this helps in improving self-awareness.

Blind-Spot Bias

This is the bias of recognizing bias in others but failing to see it in yourself. You might easily spot overconfidence in a colleague but miss it in your own actions. Generally, keeping an open mind and seeking feedback from others can help mitigate this.

Sunk Cost Fallacy

The sunk cost fallacy is a tendency to continue an endeavor once an investment in money, effort, or time has been made. A typical example is continuing a doomed project because you’ve already invested a lot in it. The key is to focus on future benefits rather than past investments.

Clustering Illusion

Clustering illusion is the tendency to see patterns in random data. For instance, gamblers often believe that a streak of bad luck must be followed by good luck. Understanding the random nature of certain events can help avoid this bias.

Negativity Bias

Negativity bias is our tendency to focus more on negative experiences than positive ones. For example, one critical comment can overshadow multiple compliments. This bias can influence our decisions and relationships; being aware of it helps maintain a balanced perspective.

Halo Effect

The halo effect occurs when our overall impression of a person influences how we feel and think about their character. For instance, if you find someone attractive, you might also assume they are kind and intelligent. Recognizing this bias helps in making more objective evaluations.

Optimism Bias

Optimism bias causes us to believe that we are less likely to experience negative events compared to others. For example, a person might underestimate their risk of getting into an accident. Awareness of this bias helps in making more realistic plans.

Pro-Innovation Bias

This is the belief that innovation is always positive and should be adopted quickly. For instance, new technology might be embraced without considering its downsides. Balancing this bias involves critical assessment of innovations before adopting them.

Neglect of Probability

This bias leads us to disregard the actual likelihood of events occurring. For example, people often underestimate the risk of heart disease while overestimating the risk of shark attacks. Understanding probability and statistics can help mitigate this bias.

Placebo Effect

The placebo effect is when believing in the efficacy of a treatment leads to real effects. For example, taking a sugar pill but believing it's medicine can sometimes make symptoms improve. Being aware of this can help in evaluating treatment options more critically.

Survivorship Bias

Survivorship bias is the error of focusing on successful entities while ignoring those that failed. For instance, reading about successful entrepreneurs but not those who didn't make it. Recognizing this bias helps in getting a complete picture of any situation or trend.

Framing Effect

The framing effect occurs when the way information is presented affects our decisions and judgments. For instance, a 90% survival rate sounds better than a 10% mortality rate, though they say the same thing. Being aware can help in analyzing information more objectively.

Acting Without Full Information

Sometimes, we make decisions without gathering all relevant information. For example, rushing to accept a job offer without researching the company. Pausing and seeking out the full picture can lead to better judgments.

Temporal Bias

Temporal bias involves giving undue importance to the timing of information. For instance, placing more value on recent events while disregarding past patterns. To counteract this, focus on long-term trends and holistic data.
