Every day, we make countless decisions, from what to eat for breakfast to more complex choices about relationships and finances. Interestingly, the methods by which we arrive at these decisions can vary widely, often without our conscious awareness.

Have you ever encountered someone who confidently asserts their expertise on a subject, only to find that their understanding is fundamentally flawed? Perhaps they are unable to grasp the intricacies of a topic yet demonstrate an unwavering belief in their abilities.

Have you ever looked at someone else's mistake and immediately thought, "They must be incompetent"? Meanwhile, when you make the same mistake, do you find yourself saying, "I just had a bad day" or "It was an unavoidable situation"?

Have you ever found yourself in a group project where one or more members seemed to contribute significantly less than others? Perhaps you've noticed a pattern of behavior where individuals put forth minimal effort when working as part of a larger team compared to when they are on their own.

Have you ever been certain of a detail from the past, only to discover that your memory of it is incorrect? Perhaps you vividly remember a line from a film or a historical event, only to find that it unfolded differently than you recall. This phenomenon has a name: the Mandela Effect.
