Contextuality

Contextuality is a concept in quantum physics that suggests the outcome of a measurement depends on the specific situation or other measurements being performed simultaneously. Unlike classical systems, where properties are fixed regardless of how you measure them, quantum systems can exhibit different results based on the context of the measurement setup. This means that the properties of tiny particles like electrons or photons are not absolute but are influenced by the measurement conditions, highlighting the unique and non-intuitive nature of quantum behavior.
