This is where logic is helpful. It seems to me if they were genuinely skeptical would be over the efficacy of the masks, not because of mixed messages. If they were genuinely skeptical, logic would say "it's better than nothing". I hear this reasoning frequently, but I am not really trusting of it. To me it seems that if they didn't know what to do, they'd err on the side of caution and put a barrier between their face and the air. I could be wrong, but my opinion is it seems more likely they are "skeptical" because they don't want to wear the mask and are looking for any excuse not to wear it. That falls much more in line with human nature than being scared of the government.
