Environmental factors evaluated in the RCTs
We tested the impact of two environmental factors on PhD students’ research practices in two separate RCTs:(1) Exposure to a post-doctoral researcher who experienced a similar situation and chose the DRP; (2) exposure to a supervisor who was consulted and did not object to the DRP.The first trial explored the impact of exposure to an environment in which a postdoctoral researcher described the experience of committing a detrimental practice in a similar situation vsThe second trial explored the impact of exposure to an environment where the supervisor was consulted, but the supervisor did not object to the detrimental practice (i.e. the supervisor agreed with the student’s decision) An example of a vignette is provided in Table
