Everyday life offers ample opportunities to gain an advantage through misreporting.
The aim of this research project is to investigate lying behavior by focusing on two specific characteristics: time pressure and gender.
As far as time pressure, existing literature is rather controversial as it is reported to both increase honesty
and decrease it.
We would like to argue that these opposing findings may well be the result of a methodological flaw. Most studies use the dice-in-the-cup paradigm to measure honesty.
However, a lot of people have a readily available default for this situation: claiming a roll of 6.
In order not to trigger this automatic response, we propose a variant of the dice-in-a-cup paradigm where regular dice pips are replaced with colors.
As opposed to regular dice with pips, we expect that the participants do not have a default response with respect to which color to report.
The very same channel, namely that lying under time pressure is driven by experience, may as well be able to explain gender differences in lying.
We would like to argue that since men gamble more often than women, they accumulate more experience with rolling the dice and by extension, misreporting their rolls. Under time pressure, an intuitive answer formed by experience is triggered and so we expect when using regular dice, average reports by men are higher than those by women.
By contrast, when using dice with colors, gender differences are expected to vanish under time pressure.

Experimental Details
Combinations of time pressure and various dice types are used as a means to elicit the natural proclivity to lying in male and female adults.
Intervention Start Date
Intervention End Date
Primary Outcomes
Primary Outcomes (end points)
Inferred lying rate at the group level.
Primary Outcomes (explanation)
The distributions of reported outcomes by treatment group are compared to a uniform distribution: If all participants reported honestly, each of the six different outcomes should be reported with the same probability as a fair six sided die will be used.
Secondary Outcomes
Secondary Outcomes (end points)
Mouse movement, die recall, payoff association recall, time pressure perception, decision automaticity.
Secondary Outcomes (explanation)
Mouse movement is used as proxy for the underlying reasoning processes.
Experimental Design
Experimental Design
Participants privately roll a die and subsequently report the outcome of their roll on a computer screen in order to determine their payoff.
The die is rolled with the help of a dice tower in order to ensure randomization.
The type of die used as well as time dimension for reporting results are varied between participants.
Four different combinations are planned: colored dice and time pressure, colored dice and no time pressure, numbered dice and time pressure as well as numbered dice and no time pressure.
Experimental Design Details
Randomization Method
The draw of a ball from an urn determines the computer seat. Each computer seat has either treatment assigned to it. All treatments are run concurrently.
Randomization Unit
Was the treatment clustered?
Experiment Characteristics
Sample size: planned number of clusters
Four treatments; between-subject.
Sample size: planned number of observations
200 participants altogether.
Sample size (or number of clusters) by treatment arms
50 participants in each of the 4 treatment groups, with an equal share of males and females.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
