reminder that in 2020 Yale conducted an interventional clinical trial on vaccine messaging. They call each 'arm' an intervention treatment.
Such goodies as:
Personal freedom message - COVID-19 is limiting people's personal freedom and by working together to get enough people vaccinated society can preserve its personal freedom [Did.Not.Know. Society has personal freedom?]
Economic freedom message - COVID-19 is limiting peoples's economic freedom and by working together to get enough people vaccinated society can preserve its economic freedom.
Self-interest message - COVID-19 presents a real danger to one's health, even if one is young and healthy. Getting vaccinated against COVID-19 is the best way to prevent oneself from getting sick.
Embarrassment message - the danger that COVID-19 presents to the health of one's family and community. The best way to protect them is by getting vaccinated and by working together to make sure that enough people get vaccinated. Then it asks the participant to imagine the embarrassment they will feel if they don't get vaccinated and spread the disease.
Community interest message - the dangers of COVID-19 to the health of loved ones. The more people who get vaccinated against COVID-19, the lower the risk that one's loved ones will get sick. Society must work together and all get vaccinated.
Trust in science message - getting vaccinated against COVID-19 is the most effective way of protecting one's community. Vaccination is backed by science. If one doesn't get vaccinated that means that one doesn't understand how infections are spread or who ignores science.
