> They are disregarding doctors and scientists all over the planet, because they think their politicians are incompetent?

Yeah, it's silly isn't? The logic goes something like this:

"They (politicians) control which doctors go on TV to speak and control which doctors are allowed to work in state hospitals, thus there is a selection bias in what we refer to as scientific consensus"

I noticed that the harder you try to counteract this with arguments, no matter how good, the argument veers towards the good old self-fulfilling conspiracy thought process.

I watched this conversation happen in otherwise reasonable people, in real time, people who otherwise didn't buy into consiparacy thinking about other topics.

Is there something special about vaccines that triggers people? Something psychologically deeper than other things?
