Dan Denneet is a philosophy professor who focuses on the human mind’s consciousness. Dennett says people often laugh when he tells them he works on understanding other people’s consciousness. He says it is very difficult to change other people’s consciousness because everybody thinks they are an expert on their own consciousness. However, there is a difference between having a strong opinion and having expertise in a certain field. Take video games as an example. Everyone has a strong opinion on whether video games promote violence, but not everyone is an expert on the research behind video games. In his TED Talk, Dennett says he wants to shake the audience’s consciousness.
During the first several minutes of his talk ,Dennett compares magic tricks to our consciousness. He says magic tricks, like our consciousness, seem more marvelous than they actually are in reality. He goes on to show computer-animated demos to show that we do not notice many things that happen. Dennett tells the audience the screen will show blocks that change colors, but mentions that it is difficult to recognize the change even when you know it will take place. He shares his personal experiences of viewing a Bellotto painting in North Carolina. Standing far away, Dennett thought he saw people in the painting. When he got up close, the people ended up being blobs of paint. This, he says, is an example of how your brains expects certain details or things.
Dennett says there are many times when we are subjects of experiments going on inside our brain. There are even times when you do not even know you had certain beliefs. Dennett continues to wow the audience with different paintings and explains how the brain “fills in gaps” to explain the images we see. He also explains the concept of change-blindness. Dennett says scientist often tell us things about our own consciousness that we would never dream of. This shows we are not always the expert or authority on our consciousness. Dennett concludes his talk by saying that both scientist and psychologist are working on theories to explain the human brain.
