In this video Silvia Bencivelli explains the difficulty of those, like herself, who explain science.

We have to consider that science is a concept which is a bit more complex than one which can give us a simple true/false answer, and that our brains process information in a less-than-perfect way. Truth may take on different aspects, and can adapt itself, and this is what makes scientific reporting a task which is very difficult, as well as necessary and fascinating.
