Darya Sinusoid

Darya’s love for reading started with fantasy novels (The LOTR trilogy is still her all-time-favorite). Growing up, however, she found herself transitioning to non-fiction, psychological, and self-help books. She has a degree in Psychology and a deep passion for the subject. She likes reading research-informed books that distill the workings of the human brain/mind/consciousness and thinking of ways to apply the insights to her own life. Some of her favorites include Thinking, Fast and Slow, How We Decide, and The Wisdom of the Enneagram.

The Psychology Behind Irrational Decisions

Why do people make bad decisions? How do you make a decision when there are just too many variables to consider? Many times, you make bad decisions because you don’t have enough options, information, or experience to make logical ones. However, too many options, information, or experience can also inspire irrational decisions. Let’s take a look at the three situations where excess causes irrationality: 1) too much experience, 2) too many options, and 3) too much information.

Understanding the Psychology of Loss Aversion

The 25 Cognitive Biases: Loss Aversion Bias

What is loss aversion? Why does losing something have a stronger psychological impact compared to gaining something? As the name suggests, loss aversion is the tendency to have a stronger aversion to losing something compared to gaining something. Loss aversion is an evolutionary trait passed on from early humanity when losing something—be it belongings, weapons, or food supply—was often fatal. Being cautious and avoiding loss kept early humans alive and able to procreate, meaning their cautious genes survived to the current day. Keep reading to learn about the psychology of loss aversion.

Fundamental Attribution Bias—Explained

What is fundamental attribution bias? Why do people fall for the attribution effect? Fundamental attribution bias (also known as correspondence bias or attribution effect) is a tendency to attribute others’ behavior to their disposition or personality and disregard external or environmental factors. The attribution effect is the by-product of the way your social brain works. Keep reading to learn about fundamental attribution bias, why it occurs, and how to avoid it.

The Primacy and Recency Effect—Explained

What is the primacy and recency effect? Why do we tend to remember the first and the last items well, and the middle ones poorly? The primacy and recency effect (also known as the serial-position effect) is the tendency to recall the first and the last items in a series well, and the middle ones poorly. There’s no consensus as to why this phenomenon occurs, but there are a couple of theories. Keep reading to learn about the primacy and recency effect, why it occurs, and how to overcome it.

False Causality: Correlation Doesn’t Equal Causation

What is false causality? Why do we assume causality where there is none? Humans struggle to interpret cause and effect because they confuse correlation with causation, assuming causality where there is none. For example, if a person gets the flu after they start taking vitamins, they might assume a causal relationship—taking vitamins gave them the flu—simply because the timing coincides. Let’s consider some ways the assumption of causality (where there’s none) impairs logic.

The Psychology of In-Group, Out-Group Bias

What is the in-group, out-group bias? Why do we prioritize people who belong to our in-group? In-group, out-group bias is the tendency to favor and give preferential treatment to members of the same group. By categorizing yourself as a member of a group, you make that membership part of your identity and thus focus on its positive traits. Here’s why people tend to prioritize their in-group, according to Rolf Dobelli, the author of The Art of Thinking Clearly.

The Psychology of Memory: Errors and Fallacies

Is memory a fixed record of the past? Do we always recall memories in their original state? People believe their memories are untouchable, stored away, and recalled when needed in perfect condition. However, this isn’t the case. Memory errors are proof that memory isn’t a fixed record of past events—your memory of the past is affected by your feelings, opinions, and situation. Here are some of the most common fallacies and situations in which your memory is unreliable.

Coincidence and the Law of Very Large Numbers

What is the law of very large numbers? How does the law of very large numbers help explain coincidences? The law of very large numbers is one of the key concepts in probability and statistics. The concept is quite simple: with a sample that’s large enough, even the most improbable events could happen. Keep reading to learn about the law of very large numbers and how it explains coincidences and improbable events.

Reciprocity: The Psychology of Giving Back

What is the psychology behind reciprocity? Why do we feel the need to reciprocate benevolent behavior? In social psychology, reciprocity is the tendency to return a favor or a benevolent action with another benevolent action. According to Rolf Dobelli, the author of The Art of Thinking Clearly, this phenomenon is a by-product of the human need to belong to a group. Keep reading to learn about the phenomenon of reciprocity, why it occurs, and how it’s used as a tool for manipulation.

The Dangers of the Single-Cause Fallacy

What is the single cause fallacy? Why does it occur? The single cause fallacy is where you attribute an outcome to a single, simple cause. The single cause fallacy occurs because we dislike uncertainty, and a single-cause pattern provides a sense of understanding. When people feel like they understand a situation, not only are they less uncertain, but they can also better withstand any uncertainty they do feel. Keep reading to learn about the fallacy of the single cause, why it occurs, and how to overcome it.
