Confirmation bias, a deeply rooted psychological phenomenon, explains why we tend to focus on information that agrees with our pre-existing beliefs and ignore or discredit evidence that challenges them. In everyday life, this invisible force shapes not only our individual decisions but also the way Thai society interprets news, politics, and even the stories we tell ourselves about our health and well-being. The significance of understanding confirmation bias is becoming increasingly clear in an era where information is abundant but polarization is rising, both globally and in Thailand.

Every day, people in Thailand—like in many countries—make decisions, big and small, often based on the information that comes most readily to mind. Whether it’s choosing a school, selecting healthcare options, or even deciding which road to take during rainy season, human judgment is rarely as objective as we might assume. One powerful but often unnoticed force at play is “availability bias,” a psychological phenomenon that shapes thinking and behavior based on the information most easily recalled, rather than all relevant facts [Simply Psychology], [Encyclopedia Britannica].
