Very briefly, my view, for what it is worth, is that there are two types of people:

1. Those who accept everything they are told, especially by those they believe are in authority.

2. Those who question what they are told.

If you are a type 1 person, you will believe amalgam is safe as it is promoted by most dentists. If you are type 2 person, you are more likely to not only question the safety of amalgam, but other things we are told aswell.

I'm definitely type 2 person. I don't take things at face value and always question what I am told. Therefore I do believe that some, not all, conspiracy theories are true. I personally think it is very naive to believe we are always told the truth.
