What is story bias? Why do people remember stories better than facts? Story bias is the tendency to interpret information as part of a story even though the facts don’t actually support the narrative. Stories are easier to remember than other types of information, which is why we rely on them instead of facts. Keep reading to learn about story bias, why it happens, and how to overcome it.
What is cognitive dissonance? How do people resolve the uncomfortable feeling that arises as a result of dissonance between cognitions and actions? In psychology, cognitive dissonance is the mental discomfort that occurs as a result of holding two conflicting cognitions (e.g. beliefs, values, or attitudes) or acting in ways that contradict those cognitions. To ease this discomfort, people tend to deny the facts or rationalize their thinking to restore cognitive consonance. Keep reading to learn about the psychology of cognitive dissonance.
What is the neglect of probability bias? Do you consider the probabilities of possible outcomes when making decisions? Neglect of probability bias is the tendency to disregard probability or risk when making decisions in the face of uncertainty. The most optimal choice is the one that has the highest probability of turning out well, but people tend to opt for the option that will have the biggest positive impact if it occurs, regardless of how likely it is. Here’s why we tend to neglect probability when making decisions.
What is hyperbolic discounting bias? Why is the brain so prone to seeking immediate gratification? Hyperbolic discounting bias is the tendency to crave immediate gratification and the willingness to sacrifice an unreasonable amount of money, time, or effort for that immediacy. According to Rolf Dobelli, the author of The Art of Thinking Clearly, humans are hardwired to opt for immediate reward (in the past, it helped us survive), but more often than not, it inspires bad decisions, like paying a high amount to get something quicker. Keep reading to learn about hyperbolic discounting bias, why it happens, and how to
What is the affect heuristic? How does the affect heuristic influence decision-making? The affect heuristic is a mental shortcut in which your brain makes rapid subconscious judgments of like or dislike. These “affects” influence your risk-benefit analyses: If your immediate judgment is good, you’ll focus on the benefits of a situation, if the affect is bad, you’ll focus on the risks. Keep reading to learn about the affect heuristic and its implications for decision-making.
What is the salience effect? Why does the brain tend to focus on the most flashy, salient stimuli to the exclusion of everything else? As the name suggests, the salience effect is the tendency to focus on the most salient stimuli in the environment. The salience effect relies on your past experiences. You might notice certain unusual details due to, for instance, your career or past experiences, while someone else would notice different details. Keep reading to learn about the salience effect, why it occurs, and how to overcome it.
What is déformation professionnelle? How can having too much experience in your area of expertise limit your perception of the world? Déformation professionnelle is a cognitive bias resulting from having too much experience in a certain field. It is defined as a tendency to see the world through the lens of one’s profession or area of expertise. Keep reading to learn about déformation professionnelle bias, why it’s problematic, and how to overcome it.
What is hindsight bias? Why does the predictability of the outcome seem higher in hindsight? Hindsight bias is where you—upon knowing the outcome of an event—overestimate your ability to have predicted it. According to Rolf Dobelli, the author of The Art of Thinking Clearly, hindsight bias is a by-product of the brain’s pattern-finding tendencies. Here’s why things seem clearer in hindsight.
What is sampling distribution? What are some of the pitfalls in working with mathematical averages in math? A sampling distribution is one of the complex math concepts many people don’t instinctively understand. The sampling distribution (or the distribution of the average) is important because averages are misleading: Your brain focuses on the average and doesn’t consider possible outliers in the distribution. Keep reading to understand sampling distribution, explained in simple terms.
What is social loafing? Why do people tend to lessen their effort when added to a group? Social loading is a psychosocial phenomenon whereby individuals put less effort in when they become part of a group. According to Rolf Dobelli, the author of The Art of Thinking Clearly, social loafing is a feature of groups, not a drawback: Early humans formed groups because the responsibility for survival was spread out rather than concentrated on each individual. Keep reading for the social loafing definition, how it forms, and how to prevent it.
