Conducting academic studies often involves field surveys. So I certainly understand when students choose the Community Center or Airbnb Facebook groups to recruit potential participants.
On the other hand, as Admins of various groups, we observe survey fatigue among members. Caused on the one hand by the fact that the questions are often very similar (lack of originality), and on the other hand by the fact that results are not published in the group (as often promised) (lack of transparency).
For this reason, we therefore generally no longer publish calls to answer any survey by clicking on a link.
We, on the other hand, encourage students to ask their questions directly in the group. This gives the participants a direct insight and may even lead to a discussion of the content (public feedback), which also benefits the group from the survey and encourages them to engage with the respective study topic.
Unfortunately, students do not make use of this opportunity so far, and they do not take advantage of the opportunity to participate in the exchange of experiences in groups and forums.
