Impressive experiment! Scientists call it the “Rubber Hand Illusion”. What does it show and why is it important?
Scientists use the trick with a fake hand to explore how the mind reacts to body ownership. When visual information (seeing the rubber hand being stroked) conflicts with tactile information (feeling but not seeing one’s own hand being stroked), the brain trusts what it sees over what it feels
It is fascinating how the human brain can be easily deceived. The same happens with cognitive biases when we make decisions. What we see, think, or feel does not necessarily reflect the reality.
