Definition:
Anchoring bias is a cognitive bias in which the mind, when making a decision or estimate, relies too heavily on the first piece of information or number it hears, and evaluates all subsequent judgments in relation to it.
Put simply, the initial piece of data becomes the “mental reference point”, pulling later judgements toward itself, even if that data is random or irrelevant.
Explanation and mental functioning:
To conserve energy, the mind tends to rely on the initial information and avoids re-analysing the situation.
As a result, a person’s judgement is shaped not by reality but around the first number or piece of information they encountered.
For example, if we ask:
“Is the population of Argentina more or less than 64 million?”
the number 64 million, even if incorrect, becomes an unconscious mental anchor.
Later, when asked “What do you think the population of Argentina is?”, most people estimate a number close to 64 million, even though the real population is around 45 million.
Mental mechanism and cognitive outcome:
When the mind encounters the first number or piece of information, it stores it in active memory as if it has “anchored” itself to it. Every later evaluation is then made in relation to that initial anchor.
The consequences of this mechanism are as follows:
- The mind abandons free analysis and moves only around the anchor.
- New data receive less attention or are interpreted in ways that fit the anchor.
- Judgements are shaped by the initial anchor, not by objective reality.
- The mind becomes vulnerable to psychological manipulation in advertising, pricing, or policymaking.
Classic example:
The renowned psychologists Daniel Kahneman and Amos Tversky demonstrated that even the order of numbers can create an anchor in the mind.
In their experiment, two groups were asked to estimate the product below rapidly:
- Group 1: 8×7×6×5×4×3×2×1
- Group 2: 1×2×3×4×5×6×7×8
The average answer of Group 1: 2250
The average answer of Group 2: 512
The correct result for both sequences was 40,320, but why was there such a significant difference between the two groups?
Because the minds of the first group started with the large number “8” and anchored around it, while the second group began with a small number and their minds became anchored in a lower range.
Real-life examples:
1. Purchasing and pricing:
Anna wants to buy a car. The seller initially announces the price at 25,000 dollars and, a few days later, says he is willing to sell it for 20,000 dollars.
Anna feels she has made a good deal because her mind is anchored to the initial price (25,000 dollars).
Yet if the price had been stated as 17,000 dollars from the start, this offer would not have seemed attractive at all.
2. Expectation experience:
If one group is told the waiting time is 20 minutes and another group is told it is 30 minutes, and both groups are admitted after 25 minutes, the first group will be dissatisfied and the second group pleased.
This is because each group uses the “announced expectation” as its reference point for judgement.
3. Everyday shopping:
When an item is priced at 59 dollars instead of 60, the mind perceives it not as one dollar cheaper than 60 dollars, but as ten dollars cheaper, because the number 50 remains anchored in the background of the mind.
Here, it should be noted that …
- The first number or piece of information, even if random, shapes our judgement.
- The mind tends to compare differences with the starting number, not with real data.
- An anchor can begin even from a joke, an advertisement, or a simple question.
- The later new data are examined, the stronger the anchor becomes.
- Awareness of the anchor is the first step in neutralising its effect.
Why is this bias dangerous?
- Leads to the acceptance of unfair prices or conditions.
- Creates judgement errors in financial decisions and negotiations.
- Locks the mind into an incorrect point of comparison.
- Steers public opinion in the media and politics through fabricated numbers.
- Prevents critical analysis and flexible thinking.
How can we recognise it and respond?
To identify this bias, we can ask ourselves:
– Is my evaluation based on reality, or on the number I heard first?
– If the initial number changed, would my decision change as well?
– Has my mind fixated on the first piece of information, or have I considered the new data?
A suitable response might be:
- Noting down the initial number to stay aware of its influence on judgement.
- Actively seeking independent data before making a decision.
- Updating information consciously and focusing on reasoning rather than emotion.
Connection with Wise Education:
According to Article 26 of the Universal Declaration of Human Rights, Wise Education emphasises the ability to think freely and to avoid mental traps. An educated mind is familiar with cognitive traps and has practised how not to fall into internal traps, such as biases or external traps, such as logical fallacies, thereby preserving the freedom and independence of thought and action.
An educated person understands that the first piece of information is not necessarily correct, and that they must examine new information with an open perspective and update their analysis accordingly.
Conclusion:
Anchoring bias shows how the mind clings to the first piece of information it encounters and struggles to let it go. But a wise person learns to lift the anchor, navigate the sea of data with a clear mind and an analytical eye, and sift through everything to make the right decision.
