The concept of 'cognitive dissonance' refers to the mental discomfort experienced when an individual holds two or more contradictory beliefs, values, or attitudes, especially when their behavior conflicts with their self-image. This discomfort often motivates people to reduce the inconsistency by changing their beliefs, adding new cognitions, or minimizing the importance of the conflict. Psychologists suggest that the drive to achieve consistency is a fundamental human motivation, influencing decision-making and rationalization processes.
🎧 การบรรยาย
Professor: Today, let's talk about cognitive dissonance in a real-life scenario. Imagine a student named Mark who considers himself environmentally conscious. He always recycles and advocates for reducing plastic use. However, one day, he forgets his reusable bag and buys a plastic bottled drink at the campus store. Initially, he feels uneasy—this is the dissonance. To reduce the discomfort, Mark might quickly tell himself, 'Well, this store doesn't have any other option, and one bottle won't hurt the environment.' He might also plan to reuse the bottle for a few days to compensate. This way, he changes his perception of the action's impact, making it seem less contradictory to his eco-friendly identity. So, instead of changing his core belief, he adds a rationalization to ease the tension.
