SYNTHETIC RESEARCH PRETEST · N=200

Anchoring effect

Numerical judgments can be influenced by an initial anchor, followed by insufficient adjustment. This adapted study compares building-height estimates after anchors of 12 and 70 floors.

Design and results

Synthetic responses followed the predicted direction. This is a directional description, not a matched human-participant test.

Mean estimate (floors)
Group	n	Result
Low anchor	100	17.53
High anchor	100	43.04

Group B minus A: 25.51.

Limitations and source

These results can help test questionnaire materials, branching and analysis workflows. They do not estimate human-population effects or replace human validation.
