This study has three interesting aspects. One, obviously the prior bias of the researchers was that anti-vaxxers/maskers are mouth breathing superstitious retards. Two, when observation showed that they were actually looking for hard, replicable evidence, the researchers are baffled. Their conclusions show that they are having a hard time reconciling their other bias in favor of masks and vaccines with the diligence of their subjects. They may know in their hearts that they, the researchers, are the ones who are avoiding evidence. Finally, the conclusion about education being the key determinant is obviously wrong, it is something else, but they can't imagine what.
