Observer Effect

The observer effect refers to changes that occur in a system when it is measured or observed.

Overview

In physics this is associated with quantum experiments, where the act of measurement can affect the system. The term is sometimes misapplied to suggest that consciousness causes physical change.

Key Insight

In quantum mechanics the effect is about measurement and interaction, not necessarily conscious observation.

Scientific Status

Well understood in physics; often misrepresented in popular discourse.

FAQ

  • Does the observer effect mean consciousness creates reality?

    No. In physics, observation refers to physical measurement, not to conscious awareness per se.
