In the realm of quantum mechanics, the concept of observation and its influence on the observed system is a topic of debate and interpretation. The phenomenon you're referring to is sometimes associated with the observer effect or the measurement problem in quantum mechanics.
In quantum mechanics, the act of measurement or observation is thought to collapse the wavefunction, determining a specific outcome from a range of possibilities. However, the precise nature and implications of this collapse are still not fully understood and are subject to different interpretations.
One interpretation, known as the Copenhagen interpretation, suggests that observation causes a collapse of the wavefunction, leading to a definite outcome. According to this view, the observer influences the outcome by the very act of observing, but this influence is typically considered to be a statistical effect rather than a conscious or subjective one.
On the other hand, some interpretations, such as the many-worlds interpretation or the transactional interpretation, propose that all possible outcomes actually occur in different branches of reality or through transactions across time. In these interpretations, the observer's role is more complex and does not involve direct influence or subjective bias on the unfolding of events.
It's important to note that in the context of everyday experiences, such as reading a book or watching a movie, quantum effects are generally considered negligible and not relevant to the macroscopic world. The influence of biases, beliefs, and expectations on our subjective experiences is primarily attributed to cognitive and psychological factors rather than quantum entanglement or wavefunction collapse.
While the philosophical implications of quantum mechanics are fascinating, it is still an area of active research and debate. The exact nature of the observer's role and the relationship between quantum mechanics and subjective experience are still open questions, and different interpretations exist.
