What strategies help reduce Australian adults’ beliefs in COVID-19 vaccine misinformation?

The intervention is a short piece of written material addressing misinformation about COVID-19 vaccines and fertility. The written material was designed specifically for this study. The intervention will be delivered as part of an online experiment over the internet. After answering some questions about themselves, participants will be asked to read written information on their computer or phone screen. Participants will receive a single written intervention according to their randomised group. There will be a control group and 3 intervention groups. - The control message will provide correct information about COVID-19 vaccines and fertility. - Intervention 1 will provide correct information + information on misleading techniques. The misleading technique that the intervention provides information about is called "cherry-picking". This is where people who spread the false claim that COVID-19 vaccines cause infertility focus on some of the facts, and ignore other facts that don’t support the false claim. - Intervention 2 will provide correct information + information on untrustworthy sources. The information on untrustworthy sources focuses on what makes an information source lack credibility or trustworthiness. - Intervention 3 will provide correct information + information on misleading techniques + information on untrustworthy sources. We will require participants to view the intervention text for a minimum length of time, calculated at 100 milliseconds per word.
