There's someone in my head, but it's not me.

There's someone in my head, but it's not me. The unconscious dominates. Our conscious minds play a much smaller role in our thoughts and actions than we typically assume. Most of our behaviors, from simple motor movements to complex decision-making, are driven by neural processes occurring below the level of conscious awareness. Hidden influences abound. Factors like genetics, hormones, neurotransmitters, and past experiences shape our behaviors in ways we don't consciously perceive. Even small changes in brain chemistry or neural activity can have profound effects on personality and behavior, as seen in cases of brain injury or psychiatric disorders. Awareness is limited. We only become consciously aware of a tiny fraction of our brain's activity. Our conscious experience is more like a simplified "newspaper headline" summarizing the complex workings of our neural machinery, rather than a complete account of our mental processes.

We are aware of very little of what is "out there." The brain creates our reality. What we perceive as the external world is actually an internal construction created by our brains. Our senses don't passively record the environment, but actively interpret limited sensory data to generate our subjective experience. Perception is prediction. The brain constantly makes predictions about the world based on past experiences and internal models. These predictions shape what we perceive, often filling in gaps or ignoring inconsistencies to create a coherent experience. Illusions reveal limitations. Visual illusions and phenomena like change blindness demonstrate how our perceptions can diverge from objective reality. These limitations of perception are typically adaptive, allowing us to focus on relevant information, but can sometimes lead us astray.

We are not the ones driving the boat of our behavior, at least not nearly as much as we believe. Decisions precede awareness. Neuroscientific research suggests that our brains begin to make decisions before we become consciously aware of them. This challenges the intuitive notion that our conscious thoughts are the primary drivers of our choices. Rationalization is common. We often create post-hoc explanations for our behaviors, unaware of the true unconscious motivations behind them. This can be seen in split-brain patients who confabulate reasons for actions driven by their disconnected hemisphere. Implicit biases influence us. Our judgments and behaviors are shaped by unconscious associations and attitudes that we may not even realize we hold. These implicit biases can affect everything from hiring decisions to interpersonal relationships.

I am large, I contain multitudes. The brain as a democracy. Rather than having a single, unified "self," our brains consist of multiple, sometimes competing neural systems. These different "factions" in the brain often have conflicting goals and priorities. Emotional vs. rational systems. A key example of…
