Linking two articles, both are about something called the backfire effect which was shown in a study by dartmouth

The first link describes the effect and the second is a more recent study showing why it may not be as prevalent as once thought. However, a lack of prevalence does not mean that people who are not antivaccine can easily be dissuaded from their beliefs by facts. We have seen time and time again people using a confirmation bias in studies against vaccines. This is the same as when a flat earther performs an experiment that is meant to disprove the round earth, but when the experiment instead proves the earth is round, they find an excuse for why that is.
