Please note: To accommodate reviewer and recommender holiday schedules, we will be closed to submissions from 1st July — 1st September. During this time, reviewers will be able to submit reviews and recommenders will issue decisions, but no new or revised submissions will be made by authors. The one exception to this rule is that authors using the scheduled track who submit their initial Stage 1 snapshot prior to 1st July can choose a date within the shutdown period to submit their full Stage 1 manuscript.

We are recruiting recommenders (editors) from all research fields!

<p>The provision of information to consumers is a common input to tackling various public health issues. By comparison to the information given on food and alcohol products, information on gambling products is either not given at all, or shown in low-prominence locations in a suboptimal format. Some previous research suggests that it would be advantageous to communicate this information via the “house edge” format: the average loss from a given gambling product, e.g., “This game keeps 10% of all money bet on average”. However, previous empirical work on the house edge format only uses this specific phrasing, and there may be better ways of communicating house edge information. The present work will experimentally test this phrasing of the house edge against an alternative phrasing that has also been proposed, “on average this game is programmed to cost you 10% of your stake on each bet”, on a sample of 2,000 UK-based online gamblers. The two dependent measures are gamblers’ perceived chances of winning and a measure of participants’ factual understanding. As a further aim in order to replicate previous findings, both house edge formats will also be compared against the existing suboptimal format, the “return-to-player” (involving a further subsample of 1,000 gamblers). The optimal communication of risk information can act as an input to a public health approach to reducing gambling-related harm.</p>
