Anchoring and Adjustment Bias Estimator

Quantify anchoring bias by computing the anchor pull coefficient — the proportion of adjustment from anchor to true value actually made by subjects. Anchor pull = (estimate – anchor) / (true value – anchor)

Each component has a specific meaning:

• Anchor — The anchor recorded for the scenario being assessed.

Note: Interpret the anchoring bias result against the thresholds and context described above.

Enter the anchor for the scenario you are assessing. Quantify anchoring bias by computing the anchor pull coefficient — the proportion of adjustment from anchor to true value actually made by subjects. Anchor pull = (estimate – anchor) / (true value – anchor). Use the anchoring bias result to inform your calculation.
