The Thatcher effect
The Thatcher effect is a psychological phenomenon that occurs when we perceive a face with inverted features, such as the eyes and mouth flipped upside down, which makes it difficult for our brains to recognize the face properly. When viewed upside down, the altered face seems normal at first glance, but looks strange when turned upright. This effect highlights how our brain processes faces through specific configurations and emphasizes the role of orientation in our facial recognition abilities. It demonstrates the challenges in distinguishing familiar faces when they're altered in unexpected ways.

The Thatcher Effect is a visual phenomenon that occurs when a face is turned upside down, making it difficult for the brain to recognize it, even when features are distorted. Named after a famous image of Margaret Thatcher, the effect shows that while we can easily identify normal, upright faces, our ability to recognize and process facial expressions is compromised when the orientation is flipped. This highlights how our brains are specifically tuned to analyze faces in a certain way, demonstrating the importance of orientation in facial recognition and perception.
