The Zeigarnik Effect: The Psychology of Memory

What is the Zeigarnik effect? Why do we tend to forget projects we are done with?

According to Rolf Dobelli, the author of The Art of Thinking Clearly, the brain does this for efficiency—once the task is complete, it deems it unimportant and discards it to free up mental space. Keep reading to learn about the Zeigarnik effect, why it happens, and how to overcome it.

The Dangers of the Sample Selection Bias

What is self-selection bias? How does self-selection bias influence research findings? Sample selection bias is a common issue in psychological studies that involve statistical analysis. Specifically, people only join studies they’re comfortable responding to, which alters your data. Those who might provide embarrassing or somehow “undesirable” responses simply won’t take part, narrowing your study’s scope and skewing the results. Here’s how sample selection bias skews research results and how to work around it.

How the Need to Belong Causes Logical Fallacies

Liking Bias: Why We Ignore Faults in People We Love

Why is group membership so important? Where does the human need to belong stem from? One of the evolutionary traits that most influences you is the desire to be in a group. For early humans, group membership was necessary for survival. Those who left the group died, while those who stuck to the status quo survived and reproduced. Thus, your brain is genetically wired to fit in. Although the human need to belong has evolutionary value, it causes some fallacies in the way we interpret other people’s behavior. Let’s explore some fallacies resulting from our need to belong.

Rolf Dobelli: What Is Social Proof?

What is social proof? Is it always a good idea to follow the crowd? Social proof is a psychosocial phenomenon whereby people copy others’ behavior before participating in that behavior themselves. This tendency had survival value in the past: If everyone ran away, you ran too because there was probably a predator nearby. However, in modern times, most of our decisions are not life-or-death decisions, and following the crowd can often lead you astray. Here’s why, in modern times, social proof can often do more harm than good.
