About this episode

This episode explores the concept that our perception of reality may be constructed rather than direct, examining predictive processing and the brain's internal model of reality.

What if you’ve never actually seen reality?In this investigation, we test a simple idea:If perception worked like a rendering system… what would we expect to find?We break it down step by step:• Is perception direct?• Is perception complete?• Or is something constructing what you see?From blind spots and attention limits…to predictive processing and real-time updates…the evidence points to a surprising structure:You are not receiving reality directly.You are experiencing something generated.If true, this raises a deeper question:What exactly is being rendered… and from what?This episode explores:• Predictive processing (Friston, Seth, Clark)• Attention and perception limits• The brain’s internal model of reality• Why perception must be fast, selective, and constructed📚 RESOURCES / FURTHER READINGPredictive Processing / Brain as Prediction SystemRao, R.
