You Actually Share Your Brain With a Silent Stranger

This reminds me of two mind-boggling discoveries I’ve had about the human mind. The first is that the two halves of your brain act somewhat independently. And in rare cases, people’s left and right halves are “split” apart, and they act entirely independently - e.g. their left and their right hands will act separately, or even argue with each other. CGP Grey made a great video about this: [this video] The other is that most people have a “voice” inside their head - e.g. when they read, they hear their own voice inside their head reading; their thoughts are like sentences they “hear;” they could look in the mirror have a conversation with themselves. Some ~10% of people do not have this internal monologue. [link] [link]

This reminds me of the following quote: "Coding largely involves the 'logical part' of your brain. It tends to not include the 'language part' of your brain. This is one reason why comments you add to code are so useful: they force you to engage both parts of your brain and therefore get better results. This is also why when you go to explain a problem to a colleague, you often have a flash of brilliance and solve the problem: you are reframing the problem using a different part of your brain and the different part of your brain helps solve the problem." I'm sure some readers here will say this is preposterous and there is no such thing as having "two parts of your brain". To them I suggest watching: 1. "You are are two" (about people with their corpus callosum being severed) [this video] 2. "Conscious Ants and Human Hives" by Peter Watts [link]

Is it hard though? Or is the hard part ethics i.e. personhood, and because the terms are conflated that makes consciousness hard, since it means you cannot accept what consciousness is without needing to also define ethics. Drop the idea that consciousness is sufficient or required for personhood in favor for something more behaviourally consistent like cuteness or power, and things become clearer. There is a part of you which simulates social interaction by learning models of various other agents it has inferred the existence of. As can be expected from something which is looking for agents based on indirect clues, we know this part does struggle with accidentally assigning agency to things which clearly lack consciousness i.e that damned sharp rock you stepped on twice. This part of you is capable of simulating a finite number of simultaneous such agents at a time, meaning it will focus on, as a whole, being able to predict the actions of the agents most often observed. It is also why we would expect it to replace groups of people you only interact with as a group as a "them". It is also very common that the most significant agent to simulate would be you. Hence one of the models being simulated is you. This is what generates the perception of consciousness, why it is you yet separate. It predicts the cognitive bias of the mind body duality, yet maintains the perception of consciousness. A part of you is constantly trying to explain your own actions, but critically, while w
