The literature is rich in evidence of substantial heterogeneity in individual investment decisions, such as the choice of portfolio structure and savings behavior. The way individuals build their financial portfolios has been an increasingly relevant issue for economists and policy-makers alike. Economic theory suggests that household portfolio choice depends, among other things, on an individual's level of patience and willingness to take risk. These factors are also understood as the root of many economic phenomena (Donkers & van Soest, 1999).The study on financial decision making is challenging because individual preferences are difficult to measure. The literature has proposed distinct frameworks, such as the sophisticated models of the well-established prospect theory or the quasihyperbolic discounting model, to elicit relevant parameters. Collecting data on portfolio selection may also be complicated. Real-life data on portfolio choices can be difficult and expensive to obtain. Survey data are usually easier and cheaper to collect, but findings based on it cannot always be generalized. Incentivized laboratory experiments offer an interesting trade-off between generalizability and cost efficiency.There is little consensus in the literature on how the level of patience and willingness to take risk should be measured to ensure consistent and reliable results. Financial advisors and private bankers still rely on rather rough estimates based on nonsophisticated measuring methods. Previous studies investigating different elicitation methods have revealed puzzling outcomes and large inconsistencies. A low correlation among different measures is a recurrent finding (see, e.g., Crosetto & Filippin, 2016;Szrek et al. 2012;Pedroni et al., 2017). Although self-reported measures for risk-taking show slightly higher consistency
