Vignette dimensions and levels. Experimental variation of eight dimensions (N_Vignettes = 256)

Dimension	Levels	Examples of two contrasting vignettes
Gender	▪Male ▪Female	Example for males: • Alexander is 21 years old. You do not know Alexander. • He works as a harvester on a farm in Germany. • He currently lives in a county where Corona hardly occurs. • Recently, Alexander spontaneously visited a friend with whom he wanted to have a coffee. • Because Alexander developed a slight cough a few days later, he went to his family doctor. The doctor ordered a Corona test. • However, Alexander does not have any relevant previous illnesses. • While Alexander was waiting for the test results, he went into domestic quarantine as prescribed. • Today, the results came back. They confirmed that he does not have Corona, but only the flu. Example for females: • Alexandra is 61 years old. You do not know Alexandra. • She works as a foreign seasonal harvester on a farm in Germany. • She currently lives in a county where Corona is very widespread. • Recently, Alexandra spontaneously visited a friend with whom she wanted to have a coffee. She knows that the friend is currently waiting for his test results and has a few Corona symptoms. • Because Alexandra developed a slight cough a few days later, she went to her family doctor. The doctor ordered a Corona test. • In fact, Alexandra has a relevant pre-existing condition (cardiovascular problems). • While Alexandra was waiting for the test results, she, however, did not go into domestic quarantine as prescribed. • Today the results came back. They confirmed that she does have Corona.
