I have to disagree. The primitive hindbrain and midbrain (the lizard parts of our brain) are the parts that reverts to simple categorisation for survival purposes, and the more developed cerebral hemisphere higher functions shut down in that scenario. If we are to behave like civilised humans rather than panicked beasts then it is our more developed higher brain functions that we rely on to do that and they don’t require categorisation as most of humanity is cleverer and more developed than that. The lower primitive functions are for emergency survival autopilot purposes. I would hope that most of us in this forum don’t rely on lizard brain functions for the majority of our living. Hence my opinion that the lack of need to categorise things / people in order to live in a modern civilised world is desirable. Just saying.
See below summary;
The brain categorizes information for survival by rapidly identifying threats to trigger immediate, protective responses like fight, flight, or freeze. This categorization system, rooted in the older, more primitive parts of the brain, allows it to quickly process the overwhelming flow of data by assigning experiences to categories rather than analyzing each one individually. This allows for fast, often unconscious, decisions—such as labeling a speeding car as dangerous—to keep the individual safe.
The survival brain's 3 processes;
1. Threat detection: The brain's older regions, particularly the brainstem and limbic system, are highly attuned to danger.
2. Categorisation: Experiences are categorized as safe or threatening, good or bad, without requiring higher-level reasoning. For example, it quickly labels a speeding car as a threat.
3. Hormonal response: When a threat is perceived, the survival brain floods the body with stress hormones to prepare it for immediate action.
Fight, flight, or freeze: This hormonal response triggers one of three automatic reactions:
Fight: Confront the threat.
Flight: Escape the threat.
Freeze: Become still to avoid detection.
Higher-level functions go offline: During this survival mode, more complex functions like reasoning, problem-solving, and rational decision-making (handled by the frontal lobe) are temporarily shut down to focus exclusively on the immediate threat.
