Choice blindness manipulation detection to gauge the stability of risk preferences?

The study that this experiment was part of is currently under review for publication: Scholten, L., Choice blindness manipulation detection to gauge the stability of risk preferences? An experiment in constructing risk preferences for urban drainage and flood prevention.

The aim of the experiment was to investigate the coincidence of choice blindness manipulation detection with risk preference (in)stability across five outcome domains. A short description of the experiment and hypotheses can be found at https://osf.io/54nuw.

Choice blindness in risk preference elicitation

Built with Experiment

Preview

This experiment contains a choice experiment with two-outcome gamble trials for studying effects of choice blindness manipulation on risk preference elicitation. Two experimental conditions are distinguished, wherein risks and outcomes of the gambles are either presented in numeric format or as (visual) icon arrays. The experiment also includes modules to measure:

• a 2 item measure of valence and arousal
• several items to measure cognitive abilities via the Cognitive Reflection Task (CRT), Berlin Numeracy Task (BNT) and Graph Literacy Tasks
• priority ranking of five different outcome domains of urban drainage (wastewater) management considering their outcome ranges
• experience with the domain outcomes
