Integration and Information
What if consciousness could be measured rather than just pondered? On this episode of Mind Shift, Kate dives deep into Integrated Information Theory (IIT), the bold proposal that consciousness is not just correlated with, but actually identical to, a specific kind of information integration that can be mathematically quantified. Exploring the radical implications and unsettling predictions of this approach, Kate challenges us to rethink the boundaries of what can and cannot be conscious.
In today's episode, Kate explains the foundations of IIT, examines why its measure of consciousness, symbolized by the Greek letter phi, matters, and considers how this theory could upend everything from neuroscience to ethics. With clear examples and a critical lens, Kate traces how IIT opens new frontiers in the science of mind, while also raising new puzzles and dangers.
"Consciousness isn’t something over and above integrated information that needs separate explanation; the intrinsic cause effect structure is experience from the inside." ~Kate
