A cognitive blind spot refers to a gap in a person's awareness or understanding, often caused by biases or preconceived notions. This phenomenon can lead individuals to overlook important information or fail to recognize their own limitations in judgment. Cognitive blind spots can affect decision-making and problem-solving abilities, resulting in errors in reasoning. These blind spots are often influenced by factors such as confirmation bias, where people favor information that confirms their existing beliefs, or groupthink, where the desire for harmony in a group leads to poor decisions. Recognizing and addressing these blind spots is essential for improving critical thinking and achieving better outcomes.
