You can trust what’s in front of your eyes, right? Turns out… not really. Everything we see is processed through a filter of our prior expectations. Our brains fill the gaps in the data they receive to create a “reality” that we can understand. If everything we see and hear is just a construct, are we all living in our own hallucinations?  Anil Seth, Professor of Cognitive and Computational Neuroscience at the University of Sussex and author of Being You: A New Science of Consciousness, explains our world of illusions to Olly Mann.  • “There is a real world out there – but we experience it as a construction. We never experience things as they really are. We experience the world as WE are, not as IT is.” – Anil Seth • “We think our brains are ‘reading out’ the world but it is totally the other way around… The brain is continually making predictions about what is out there.” – Anil Seth Buy Being You: A New Science of Consciousness through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission for every sale.
