Interventions

Intervention(s)
Intervention (Hidden)
We compare a priming with three different scenarios in an online experiment.
- Optimistic outlook on the future (mentions only positive aspects regarding the corona crisis, e.g. shrinking numbers of daily new infections)
- Pessimistic outlook on the future (mentions only negative aspects regarding the corona crises, e.g. the risk of a strong second wave of infections)
- Balanced outlook on the future (mentions positive and negative aspects)
- Control priming (structurally similar text that deals with research in the outer space)
