A single sentence from a colleague still lingers. They called you forgettable, or pointed out a weakness, or left a comment that made your stomach drop. Years later, you cannot recall a single compliment from the same person, or even from that entire year. Yet that one criticism remains vivid, playing on a loop whenever you doubt yourself.
This is not weakness. It is how your brain is built.
Negativity bias is when we place more importance on negative feedback and remember it more acutely than positive feedback. Researchers have titled this phenomenon "Bad is stronger than good", and the effect ripples through workplaces across the world. Negative stimuli capture attention, are more likely to be remembered, and are prioritised over positive information, thereby amplifying cognitive processing.
Why does the human brain work this way? The answer is ancient. People tend to prioritise negative information over positive information across different psychological contexts, a bias believed to have evolved as a survival mechanism, with avoiding harmful stimuli being more essential to survival than seeking out beneficial ones. In the savanna, noticing the predator was more valuable than noticing the ripe fruit.
But modern workplaces are not savannas. The threat is not lethal, yet our nervous systems respond as though it were. Our brains often interpret negative feedback as an attack, which triggers stress reactions, and instead of using feedback as a constructive stimulus, we go into fight-or-flight mode and defend ourselves or withdraw.
The imbalance is striking. Research into healthy relationships found that stable and happy partnerships maintain a five-to-one ratio of positive to negative interactions, suggesting that simply offering one compliment does not offset a single criticism. The math of human psychology demands abundance to counterweight scarcity.
Yet this mechanism is not entirely fixed. Gaining distance and perspective from feedback puts us into a positive state of mind and prompts us to consider solutions as a way of coping. Rather than dwelling on the comment immediately, stepping away can rewire how you process it.
There is also genuine value in building what organisational researchers call psychological safety. In teams where it is expected to openly address concerns, questions, ideas and mistakes without fear of negative consequences, psychological safety is crucial for employees to feel confident in giving and receiving honest feedback. When a workplace creates this environment, criticism loses its edge. It becomes information rather than judgement.
The person who called you forgettable probably has forgotten saying it entirely. Your brain, however, made a file and locked it away. That is not a flaw in you. That is how all of us are wired. Knowing this does not erase the sting, but it does change what the sting means. You are not broken for remembering. You are human.
