I enjoy following new research on scientific journals, but I get puzzled by conflicting results. How do you decide which side to take?

The only way to tell which side is right is through hindsight. Conflicting results simply mean that more information is needed before one hypothesis or the other (or neither) can be accepted as established fact. The progress of scientific discovery often resembles the story about the blind men and the elephant; discoveries are made a piece at a time, and the pieces may seem to contradict each other until all of the blank spaces are filled in. When I see conflicting results, I try to be impartial and trust that more data will resolve the question.

Some people find conflicting results upsetting, as if disagreements among scientists somehow undermine the validity of science in general. However, these disagreements serve as a powerful self-correcting force, encouraging new experiments and observations, since most scientists ultimately have the same goal: to describe the universe and explain how it works as accurately as possible.

I think you make a good point here, and in most cases, I agree. But something to keep in mind is that not all research is created equal.

Some studies have better methodology than others, and some studies are in more reputable journals than others. So, in many cases, you can evaluate the studies to see which one is "better."

I put better in quotes because as badaspie says, science is not absolute.

For example, a lot of research into complimentary and alternative medicine is not held to the same standards as traditional medical research.

You're absolutely right about not all studies being of equal quality, and I should have specified that my impartiality applies to *peer-reviewed* journals in which a panel of experts (who presumably know more about their field than I do) have already vetted the quality of the studies being published.

However, even the most reputable journals can be fooled. The Lancet was fooled by Andrew Wakefield's (in)famous study linking autism to childhood vaccines. It turns out that Dr. Wakefield falsified medical histories, faked test results, and accepted funding from lawyers planning to sue vaccine manufacturers during the course of his study, but none of that was apparent at the time the study was accepted for publication.

And if noted experts can make mistakes like this, it's not surprising that the general public (or even the educated public) gets confused over what is science and what is bunk.
