Definition:
Confirmation bias is a cognitive tendency in which the mind searches for, interprets, and remembers only the information that aligns with its prior beliefs, while resisting information that contradicts them.
In this state, a person does not see the whole of reality, but only the part that confirms their initial belief.
In other words, the person approaches reality not to discover the truth, but to reinforce what they already believe.
Explanation and mental functioning:
To maintain psychological stability and reduce mental effort, the human mind prefers to remain within its “cognitive comfort zone.” Admitting an error or changing a belief demands significant mental energy, a state known as cognitive dissonance.
To reduce this internal pressure and protect the “comfort zone,” the mind does two things:
- It highlights and validates evidence that supports the prior belief.
- It downplays, questions, or invalidates evidence that contradicts it.
This process is largely unconscious.
Mental mechanism and cognitive outcome:
a) Mental mechanism:
- Selective search: Deliberately or unconsciously consulting sources that confirm the prior belief.
- Biased interpretation: Interpreting ambiguous evidence in favour of the initial belief.
- Selective memory: Remembering confirming cases more strongly and forgetting contradicting ones.
b) Outcomes:
- Greater bias and dogmatism.
- Formation of “echo chambers”, where a person continuously hears only like-minded voices.
- Weak decision-making due to ignoring important and warning evidence.
- Social polarisation: Each group sees only evidence that confirms its own beliefs.
Real-life examples:
1. Social media:
Algorithms show us exactly the content we already like. If someone believes in a conspiracy theory, their entire digital world becomes filled with evidence that appears to confirm that conspiracy.
2. Medicine:
A person who believes in a superstitious treatment considers the accidental recovery of one individual as conclusive proof of the method’s validity, while ignoring or justifying thousands of cases where it fails or causes harm.
3. Politics:
Supporters of a party view a small mistake by the opposing party as a national disaster, yet justify serious corruption within their own party.
4. Social stereotypes:
If someone believes that “the people of a particular city are stingy,” every frugal action they see reinforces that belief, while dozens of generous actions go unnoticed.
5. Management:
A manager who is enamoured with a new idea reads only the positive market reports and dismisses the technical team’s warnings about potential failure as “pessimism.”
Here, it should be noted that…
- High intelligence does not prevent confirmation bias; intelligent individuals are simply more skilled at justifying their existing beliefs.
- This bias often occurs unconsciously.
- Confirmation bias distorts both the reception of information and the recall of memories.
- The mind’s goal in this process is “preserving the belief,” not “finding the truth.”
Why is this bias dangerous?
- It prevents learning and the correction of mistaken beliefs.
- It makes dialogue and social understanding difficult.
- It leads to poor decision-making in medicine, economics, politics, and everyday life.
- It creates an illusion of knowledge and closes the path to critical feedback.
How can we recognise it and respond?
To recognise it, we may ask ourselves:
– Am I seeking “truth” or simply “being right”?
– If my belief were wrong, what evidence would be required to disprove it?
– When confronted with an opposing view, do I become curious or upset?
– Are my sources of information diverse?
A suitable response might be:
- Making a deliberate effort to seek evidence that challenges our own beliefs.
- Engaging in dialogue with people who hold different perspectives.
- Accepting that making mistakes is a natural part of the learning process.
- Pausing before accepting or sharing information that aligns with our preferences.
Connection to Wise Education:
Wise Education, in accordance with Article 26 of the Universal Declaration of Human Rights, calls us to see realities as they are. Only by accurately and precisely seeing reality can we transform it into truth and establish peace within ourselves, among human beings, and between humanity and nature. Yet two mental traps, cognitive biases and logical fallacies, prevent us from seeing the whole of a reality.
Confirmation bias, by enclosing the mind within its own voice, turns a person into both prisoner and jailer inside a mental cell built from dogmatism. A wise mind, instead of seeking self-confirmation, learns to listen to others, to recognise the diversity of human experience, and to view reality not through the walls of rigid beliefs but from the perspective of an impartial judge.
A wise person also knows that confirmation bias often occurs unconsciously, which is why they devote part of their precious mental energy to self-regulation so that they do not fall into this bias or any other. [1]

Conclusion:
Confirmation bias reminds us that, rather than seeing the whole of reality to transform it into truth, the mind engages with reality selectively. An untrained mind looks for confirmation of its own assumptions in every situation.
Freedom from this bias becomes possible through honesty, curiosity, and the practice of critical thinking.
A wise person recognises the comfort of a “mental safe zone” as a sedative for the mind and, through questioning, examines their own views and those of others to see reality as it truly is.
[1] Mr Azadfar expresses this self-control on page 111 of Volume Four as follows:
“Have I missed any aspect of that concept for consideration?
Which elements have been ignored?
Am I giving too much weight to certain factors because I like them?
Am I missing relevant information because it doesn’t support my view?
Which cognitive biases have affected my comprehension of the topics?”
