The Observer Effect refers to the idea that observing a system or phenomenon can alter its behavior or state. It’s commonly discussed in physics but applies to other fields as well.
Key Examples:
- Physics: In quantum mechanics, observing particles like electrons can change their position or momentum. This is tied to the Heisenberg Uncertainty Principle.
- Everyday Life: People act differently when they know they’re being watched, like employees performing better under supervision.
- Science: Measuring temperature with a thermometer slightly changes the temperature of the object being measured.
Why It Happens:
Observation often involves interacting with the system being studied. For example:
- Light or tools used to observe can disturb particles.
- Human awareness or presence influences behavior.
In short, observing something is rarely passive—it often affects the very thing being observed.
