When we encounter unfamiliar social situations or people who appear different from what we perceive as familiar, the brain can respond with heightened alertness. Research in neuroscience suggests that the amygdala, a region associated with threat detection and emotional processing, becomes more active when we are exposed to uncertainty or unfamiliarity. From an evolutionary perspective, this response once served an important survival function. Human beings evolved to quickly assess potential threats in their environment, helping our species respond to danger and uncertainty.
In modern society, however, these instinctive responses can still appear even when no real threat exists. We may notice subtle physical reactions such as increased tension, a faster heart rate, or a feeling of discomfort when confronted with the unexpected. I think this is important because many of our unconscious biases operate below the level of conscious awareness. Without reflection, we can mistake familiarity for safety and difference for risk. The challenge for leaders is not to pretend these instincts do not exist, but to become aware of them so they do not unconsciously shape decision-making, relationships, and organisational culture. Awareness creates the possibility for more thoughtful, objective, and inclusive leadership.
