Q: Why do perceptions differ from person to person and which one should we think is correct while dealing with several of them?
Krishna: A unique consciousness pattern exists for each and every one of us depending on the biochemistry of our system, senses of your unique body and neuron circuits of our brain. Human consciousness depends primarily on the complex, integrated functioning of the brain—specifically the interactions between the brainstem (which regulates wakefulness) and the cerebral cortex (which processes sensory information, thoughts, and self-awareness). There is, for each of us, our - and only our - one way of processing the universe. It is our specific way of experiencing the universe, of making decisions and compiling memories.
This is how it works ...
Neural Networks & Integration: Consciousness requires constant, rapid communication between billions of neurons across various brain regions.
Wakefulness (Arousal): The brainstem and the thalamus control your level of alertness. If these structures are damaged, or if they are deactivated (such as during deep, dreamless sleep or anesthesia), conscious experience disappears.
Sensory Input & Blindsight: Your conscious content relies on inputs from your senses. Interestingly, your brain can process sensory data unconsciously, but for you to subjectively experience seeing, hearing, or feeling, these signals must reach higher cortical regions.
Memory & Attention: Short-term working memory and the ability to focus attention act as the frameworks for continuous, stream-of-consciousness thought.
The unique way your circuits are formed: by your experiences, knowledge, conditioning of mind, analyses based on these things, memories and their recall.
The "Sense of Self": At the highest level, human consciousness relies on the brain's ability to model its own processes, map the physical body, and create the perception of a persistent individual identity.
When several things are affecting brain processes and in dissimilar ways for individuals, the same information is seen and interpreted in different ways by separate individuals. Each person's world is different.
If you say only yours is right, that may not be correct in others' view because their perceptions have different ways of processing.
Then which one can be regarded as correct?
Context is more important and where and how the processing occurred matters.
Therefore, I think genuine critical thinkers have a 'higher degree of correctness' in assessing a situation than others. Because they can overcome several of the drawbacks of normal analysis and can reach a superior state of thinking. They can also understand things from other perspectives, while sticking to their own analysis and perception based on it at the same time.
When they think they are correct, that is not an ego based conclusion but depends on their confidence in their ability to analyse things in an accurate way.
