Prior work
This trial does not extend or rely on any prior RCTs.
People tend to wilfully ignore the consequences of their behavior on others. We examine whether this changes if they know that they will learn about these consequences after their decision? We investigate this question with an online experiment.

Primary Outcomes

Primary Outcomes (end points)
We expect the treatment group to actively inform themselves more often, compared to the baseline. This will be measured by the number of participants clicking the 'Reveal Passive Player's Payoff" button.
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
We expect subjects in the treatment group to "help" the passive players more often
Secondary Outcomes (explanation)
We expect subjects in the treatment group to click the button, which benefits the passive players more often. They might have to forego 20p to do that.

Experimental Design

Experimental Design
Subjects will be randomly assigned to pairs. One subject will be the active player and the other subject will be the passive player. The active player can choose between High and Low, resulting in payoffs of 120p or 100p. By choosing one of these payoffs, the active player also determines the payoff for passive player. There are two situations, which are equally likely to occur. In Situation 1 choosing High leads to 20p for the passive player and choosing Low to 100p. In Situation 2, the payoffs for the passive player are flipped. The information in which situation the players are in, is hidden. However, the active player can find out by clicking on the "Reveal Passive Player's Payoff" button. In other words, the treatment group has to decide if they want to get the information before or after choosing High or Low. We will use the strategy method in this experiment in order to get the information from all subjects in the active role. Only the decision of one active player in each pair is implemented.

Was the treatment clustered?

Experiment Characteristics

Sample size: planned number of clusters
340 (each subject is her own cluster)
Sample size: planned number of observations
340 subjects
Sample size (or number of clusters) by treatment arms
170 subjects in control group
170 subjects in treatment group
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
In an earlier experiment with a similar structure, but different treatment, it was observed, that 46% of the subjects in the baseline group inform themselves. Therefore, our minimum detectable effect size would be 62% (clicking the Reveal Passive Player's Payoff button) in the treatment group with a power of 0,9 and 340 subjects.
