Subheading: How to Sort Through the Noise around Global Warning, the Latest Health Claims, and Other Scientific Controversies.
A similar book to Curious Folks Ask, this one deals with how does the scientific process work. And mainly... it doesn't. At least, not in the way we all learn it in school. Nothing is really neat and defined with science like it is in math or history.
"Without understanding why there could be legitimate reasons for scientists to come to different conclusions, it is frustrating to hear that scientists disagree, or that they have changed their minds about science-based advice they gave in the past."
Plus, it doesn't help when people have confirmation bias: "People pay attention to information that supports their viewpoints, while ignoring evidence to the contrary."
Basically, science is a complicated subject, so even though something may be proven... that doesn't mean it's right. :-)
