When to trust (and not to trust) peer reviewed science

Reason and reliability

All in all, we should feel confident that important science is solid (and peripheral science unvalidated) due to peer review, transparency, scrutiny and reproduction of results in science publication. Nevertheless in some fields where reproduction is rare or impossible – long term studies depending on complex statistical data – it is likely that scientific debate will continue.

But even in these fields, the endless scrutiny by other researchers, together with the proudly guarded reputations of authors and journals, means that even if it will never be perfect, the scientific method remains more reliable than all the others.
