Perception is constructed
Inference, not recording.
Incomplete data
The senses deliver noisy, partial and ambiguous information. The brain combines it with prior expectations to produce a stable experience that feels direct and immediate.
- Two eyes give two flat images and you experience one three-dimensional scene.
- Expectation is not a bias here; it is a necessary part of the process.
Why it feels effortless
The work is invisible because only the result reaches awareness. That is precisely why illusions are surprising: they expose a process we never see.
