Prior work
This trial does not extend or rely on any prior RCTs.
The literature has generally documented that perceptions (i.e. beliefs about others) are more slow-moving than individual attitudes, often giving rise to misperceived social norms, i.e. discrepancies between individuals' attitudes and the attitudes they believe are held by others. We study this phenomenon in the context of beliefs about attitudes towards corruption and whistle-blowing among future civil servants in Indonesia. We will conduct a survey experiment in a population of future civil servants to learn about the role of misperceived norms of corruption in shaping the decision to report on corrupt behavior, and more generally, to engage in anti-corruption activities.

Primary Outcomes

Primary Outcomes (end points)
Indicators for hypothetical whistleblowing (in response to a short vignette) and reporting of corruption observed during the past 3 years/students' studies. Intentions to complete an e-learning course designed by the national anti-corruption agency. Indicators for registration to and completion of the e-learning course designed by the national anti-corruption agency. We will also construct an index of whistleblowing behavior.

Experimental Design

Experimental Design
We conduct an information provision experiment with students enrolled at a civil service college. After eliciting students' private and second-order beliefs regarding the extent to which engaging in corrupt behavior is perceived to be shameful/embarrassing (memalukan in Bahasa), students are randomly allocated to one of two conditions: 1) no information (control group); 2) information about the true beliefs held in a group of alumni and active civil servants with respect to the extent to which engaging in corrupt behavior is perceived to be either shameful. We cross-randomize whether students receive information related to the relevant whistleblower protection legislation for civil servants. Finally, we further cross-randomize whether we introduce a garbling methodology when eliciting students' observations of corrupt behavior in the past.

Randomization Method
Randomisation done in office by a computer
Randomization Unit
We will randomize treatment status at the individual level, stratifying treatment by the faculty in which students are enrolled and by students' region of origin.
Was the treatment clustered?

Experiment Characteristics

Sample size: planned number of clusters
Randomization is at the individual level.
Sample size: planned number of observations
We will invite the entire cohort of final-year students of the civil service college to participate in an online survey during which we will administer the above survey experiment. The cohort consists of approximately 1100 students. We expect a 75 percent response rate for a total number of observations of (approximately) 825.
Sample size (or number of clusters) by treatment arms
We will randomly assign one-half of our sample to each of the main treatment conditions described above. We thus expect approximately 410 students per experimental condition.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
