helps us survive and function efficiently—but it also makes us overlook anomalies.
- Expectation Bias
We tend to believe that a realistic image should follow real-world rules. So if a hospital image “looks right,” we stop checking further.
- Selective Attention
You may focus on the patient or doctor in the center of the image and completely ignore background details where the mistake is often hidden.
- Visual Overload
Hospitals contain many small objects: wires, tools, charts, machines. Too much detail can overwhelm your attention, making it harder to isolate the error.
These psychological effects combine to make even obvious mistakes surprisingly difficult to find.
