Perception

How do we see the world?

What is perception? How do we see the world? How do our senses trick and lie to us? Through a series of simple experiments you can try at home we look at all these questions. We then delve deeper into our perception and understanding of the world around us. Most people perceive themselves as above average, can’t take on new ideas and misremember events. Being aware of this will help us all understand the world and each other with deeper respect.
