Abstract
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.

Experimental Design

Experimental Design
We will sample approximately 500 adults based in the US, fluent in English on Prolific. We target a gender balanced sample.
We randomize participants into control group (no information) and an information treatment.
Experimental Design Details
First, we recruit the benchmark population and survey them about their sleep behavior and opinions. We aim to target 200 Prolific participants (US based, adult, fluent in English, gender balanced).

Next, we will sample approximately 500 other Prolific participants using the same criteria. These participants will answer questions about their sleep, report their beliefs about the benchmark population's responses, receive treatment if any, respond to a demographic survey and report their outcome variable (signing up for a newsletter, planned sleep).

We will manipulate the information content of the treatment by strategically sampling from the benchmark population.
