A good scientist is a skeptical/cynical scientist.
And never forget the two main rules of understanding scientific findings:
1) pay no attention to what media reports say about a scientific finding. Read the paper instead. The media almost never gets things right and very often completely misrepresents them.
2) One paper is the same as no paper. Don't even think about entertaining the notion that what a single paper says is actually true. Wait until there are other papers from researchers trying to reproduce results.
