Is Reality Even Real? Part 2 | Self-Deception, Consciousness & Objective Truth
7/9/202650 min
If your perception isn't objective...How do you know what's actually real?
In Part 2 of this Decoded series, Elisabeth McKay explores one of the most unsettling questions in neuroscience and psychology: How does self-deception form, and why does it feel indistinguishable from truth?
Building on the foundation established in Part 1, this episode examines how attention, memory, emotional salience, prediction, and past experiences shape the reality you experience every day. Elisabeth explains why two people can experience the same event and leave with completely different conclusions—and why certainty itself may be one of the brain's greatest illusions.
In this episode:
- Why attention determines your experience of reality
- The Reticular Activating System (RAS) explained
- How the salience network decides what matters
- Why memory is reconstructed—not replayed
- Narrative formation and emotional meaning
- Why relationships break down over interpretation
- Trauma, prediction, and self-fulfilling prophecies
- The psychology of self-deception
- Reality vertigo and cognitive dissonance
- Plato's Cave and modern neuroscience
- Consciousness and the "hard problem"
- Simulation theory through a neuroscience lens
- Why objective truth still matters
This conversation connects neuroscience, psychology, philosophy, and behavioral science to challenge one of our deepest assumptions—that the way we experience reality is reality itself.
If Part 1 explained how your brain constructs reality, Part 2 explains why that construction becomes so convincing that it feels like truth.

Self-deception occurs when an interpretation becomes familiar, so emotionally convincing, and so constantly reinforced that it doesn't feel like an interpretation at all. It feels like the truth, and it is extraordinarily difficult to separate yourself from when you're inside of the system. If our perception is constructed, emotions influence our interpretation, memory is reconstructed, attention is selective, and if self-deception can be indistinguishable from reality itself, how do I even know what's real? Blah, blah, blah, mind melt. This is the moment that we call reality vertigo, and I do not think you can get to a healed state without facing this head-on. [dramatic music] Your brain is wired for deception, but here's the truth. Patterns can be broken. The code can be rewritten. Once you hear the truth, you can't go back. So the only question is, are you ready to listen? Hey, everyone. We are back with part two of Is Reality Even Real? Before you watch this episode, you have to go watch the one before it. So if you didn't watch part one of Is Reality Even Real?, don't watch me. Just turn me off. Go back to the other one or, or pause me. Don't listen to me. Whether you're watching or listening, just go back. Trust me, because I'm quite literally picking up where I left off on the last one. I'm not gonna go back and fill in any gaps. I'm not gonna bring you along for the ride. So just do us all a favor. Go back and listen to the one right before it. You're welcome. We were talking at the end
