TV Horizon - Season 48 Episode 4 : Is Seeing Believing? Horizon - Season 48 Episode 4 : Is Seeing Believing? 7.516/10 by 32 users Horizon explores the strange and wonderful world of illusions - and reveals the tricks they play on our senses and why they fool us. We show how easy it is to trick your sense of taste by changing the colours of food and drink, explain how what you see can change what you hear, and see just how unreliable our sense of colour can be. But all this trickery has a serious purpose. It's helping scientists to create a new understanding of how our senses work - not as individual senses, but connected together.
