The results of eliciting risk preferences depend on the elicitation method. Different methods of measuring the same variable tend to produce different results. This raises the question whether normative risk preferences can be elicited at all. Using two types of manipulation, I assess the normative value of risk preference elicitation methods. Following IRT, the results of the multiple lottery choice method are combined with two qualitative methods into a composite score. The responses of 9,235 pension fund members to a dedicated survey indicate this composite score approximates the latent variable normative risk preferences better than individual method responses do, substantially reducing measurement noise and method-specific biases. Analysis of the manipulations shows that both the results and the normative value of the risk preference elicitation methods depend on the specific amounts, order, and endowment chosen. Combining simpler methods with more advanced methods framed closely to the relevant situation increases the normative value of elicited risk preferences.
