We like to believe we are rational. That we make decisions based on data, that we analyze reality objectively and that our opinions stem from clear thinking. But the human mind works differently: it is full of shortcuts, biases, distortions and prejudices whose purpose is to simplify complexity and make the vertigo of uncertainty manageable.
Among them, one of the most dangerous and widespread is the just-world hypothesis: the idea that we live in a world where people get what they deserve and deserve what they get. This belief, deeply rooted in the collective imagination, holds that if you work hard you will do well and that if you fail it is because you did something wrong, and it serves a psychological function: it helps us feel the world is predictable and controllable. Thinking that things happen for fair reasons can give us a sense of security: “If I do things right, I will be safe.” But it also has a problematic side, because it can lead to blaming victims or minimizing situations of injustice, inequality, illness, poverty, harassment, or violence.
But this is not the only cognitive distortion we fall into. Some, like confirmation bias — seeking information that supports our ideas and ignoring what contradicts them — are ubiquitous on social networks, where algorithms amplify them and drive polarization. Others, like survivorship bias, are pervasive in meritocratic views of professional success. We celebrate those who “overcame adversity,” while ignoring those who, in similar circumstances, could not make it, overlooking many variables and turning exceptions into rules.
A third is black-and-white thinking, in which everything is either white or black, good or bad. In an era of information overload, nuance tires people. Simplicity wins. Black-and-white thinking often appears when there is anxiety, insecurity, perfectionism, emotional fatigue, or a need for control. Splitting reality into extremes can give a false sense of clarity. The problem is that life almost never works that way. Most situations are ambiguous, mixed or gradual. In other words, this bias, like all the others, deceives us.
Distortions and biases are so deeply rooted for several reasons:
1. They save mental energy. Thinking calmly, considering nuances, and questioning beliefs requires a lot of effort. By contrast, a bias offers a quick conclusion. The brain often prefers a fast answer to a complete one.
2. They give us a sense of control. Some biases help us feel the world is more predictable than it really is. The problem is they can also lead to unfair conclusions, such as assuming that someone who suffers must have “done something.”
3. They protect self-esteem. Many biases serve to preserve the image we have of ourselves. For example, the self-serving bias: “If I pass, it’s because I’m capable.” “If I fail, it’s because the exam was unfair.” Sometimes this explanation may contain some truth, but if it becomes automatic it prevents learning.
4. They are connected to emotion. When there is fear, anxiety, anger, shame or insecurity we think less clearly. Intense emotion narrows our perspective and makes certain biases surface more strongly.
5. They are reinforced by experience. When a person repeatedly interprets reality in a particular way, that mental pathway becomes more automatic. If the idea is repeated for years, the brain retrieves it quickly whenever a failure occurs. Not because it is true, but because it is well-practiced.
Moreover, these biases have a social function and help people belong to a group. We adopt beliefs or prejudices not only because we have reasoned them, but because they connect us to a family, a culture, a profession, a community, or an identity. Therefore they appear from a very early age and become automated. From a young age we learn ways of interpreting the world such as: “If I make a mistake, I’ll disappoint people,” “If someone gets angry, it’s my fault,” “If I’m not perfect, I’m worthless,” “If I don’t control everything, something bad will happen.”
These ideas may arise from family, school, social, or emotional experiences. Over time they stop feeling like thoughts and begin to feel like “reality.”
The just-world hypothesis, confirmation bias, black-and-white thinking, and all the other mental shortcuts are not individual faults: they are part of the human brain. But we can choose not to let them guide us. Thinking better is an act of ethics, of humanity, and, in an increasingly polarized and oversaturated world, also an act of resistance.
