Yes, But As A Noted Scientist...

 "Listen to the science"

TRUE AND SAD FACTS: science only shows you how things work.  It doesn't tell you what to do.  I mean, it should tell you what to do, but it's only data - it ain't yer mom. 

For example, I'm sure a lot of people who pour gas into plastic bags know that gas is flammable, and I suppose most people understand the concept of a contagious virus.  

Gathering information is one thing, but putting that information to use is quite another.  The "answer" it presents can really depend on your own ideals.  Probably the basis for the concept of the Evil Scientist.  

Plus anti-vaxxers.
