How do we use incoming sensory information effectively?

Efficiency in perception is not driven purely by what we see, but by the interaction between expectation and observation. We do not experience the world as a completely objective reality. Instead, much of our perception is internally generated, with our senses updating us on what is new, unexpected, or changing. This means that context matters. What we notice, how we interpret it, and the conclusions we draw are all influenced by prior experience, assumptions, and situational factors. Two people can observe the same environment and arrive at entirely different interpretations. Therefore, I think perception is not fixed, it is relative and shaped by context, filtered through experience, and refined through awareness. What do you think?
