This trial does not extend or rely on any prior RCTs.
This is an experimental study eliciting beliefs on sleep and bedtime behavior. The study will investigate how randomized information on sleep distribution in a population may affect individuals beliefs about sleep duration and bedtime. The subjects will be divided in three main groups: a control group that will not receive any information, and two groups which will receive different information on sleep duration and bedtime in a reference population. Subjects will be guessing summary statistics of other participants' answers and they will receive bonus amounts based on the accuracy of these guesses.

Primary Outcomes

Primary Outcomes (end points)
Planned sleep behavior
Willingness to sign up for a newsletter about improving sleep.
Beliefs about the benchmark population (benchmark group's sleep pattern, benchmark group's ideal and preferred sleep, benchmark group's beliefs about how much they should sleep). By default we will use the point beliefs, but when we elicit distributions of the participant beliefs, we will use the mode.
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
