Definition and the Tversky-Kahneman Experiment
The anchoring effect is a cognitive bias in which an initial piece of information - the anchor - systematically distorts subsequent judgments. In a landmark 1974 experiment, Tversky and Kahneman showed that a random number from a roulette wheel influenced participants' estimates of the number of African nations in the United Nations. Higher anchors produced higher estimates, and even domain experts are not immune to this effect.
How Rankings Become Anchors
The first ranking result you see on MyRank acts as an anchor for subsequent self-assessment. If your income rank shows "top 40%," that figure unconsciously becomes the reference point, leading you to expect similar percentiles on unrelated metrics.
Anchoring also occurs when tracking rankings over time. The first position you observed becomes the perceived "normal," causing overreaction to even minor fluctuations in later readings.
De-anchoring Strategies
To reduce anchoring, deliberately consider the opposite direction through a technique called "consider the opposite." If you see "top 40%," imagine scenarios where you might be in the top 10% or the bottom 10% before forming a judgment. Gathering data from multiple independent sources also weakens reliance on any single anchor.
The Value of Multiple Reference Points
The best defense against anchoring is to consult several comparison dimensions simultaneously. Rather than fixating on income alone, viewing assets, working hours, and life satisfaction side by side prevents any single number from dominating your self-perception. Providing multiple ranking axes is precisely how MyRank supports a more balanced and accurate view of where you stand.
