Summary

COVID-19 vaccine hesitancy can be observed at different rates in different countries. 1,068 people were surveyed in France and Italy to inquire about individual potential acceptance, focusing on time preferences, in a risk-return framework: having the vaccination today, in a month, and in 3 months; perceived risks of vaccination and COVID-19; and expected benefit of the vaccine. A randomized controlled trial was conducted to understand how everyday stimuli, such as fact-based news about vaccines, impact on audience acceptance of vaccination. The main experiment involved two groups of participants and two different articles about vaccine-related thrombosis taken from two Italian newspapers. One article used a more abstract description and language, and the other used a more anecdotical description and concrete language; each group read only one of these articles. Two other groups were assigned categorization tasks; one was asked to complete a concrete categorization task and the other an abstract categorization task.

abstract vs concrete texts

The main experiment involved two groups of participants and two different articles about vaccine-related thrombosis taken from two Italian newspapers. One article used a more abstract descriptive style and language, while the other used a more anecdotical style and concrete language: each group read only one of these articles. Both articles are the same length and describe an episode of vaccine-related thrombosis. The abstract text uses a more formal and impersonal language, reporting more scientific considerations; the concrete text uses a more familiar and emotional style and provides a more anecdotical description of the case. Texts were also weighted according to a concreteness semantic vocabulary. French received translated versions.Two other groups were assigned categorization tasks; one was asked to complete a concrete categorization task and the other an abstract categorization task.
