“…While these are limitations, results of the present study showed similar effects of relevant covariates (e.g., FTND) on demand measures of studies that did not use crowdsourcing (e.g., Chase et al, 2013; Schwartz, Silberberg, et al, 2021). Additionally, there appears to be good correspondence between real and hypothetical demand tasks (e.g., Wilson et al, 2016), and purchase tasks are predictive of real treatment outcomes (González-Roz et al, 2020; Schwartz, Silberberg, et al, 2021; Secades-Villa et al, 2016; Yoon et al, 2020). It is possible that participants could have responded to experimenter expectations rather than the experimental manipulations (i.e., demand characteristics/good subject effect; Orne, 1962).…”
