Should you trust news reports about studies?

by MooshiMooshi

You know how everyone complains that studies get reported in the media which then get contradicted a year or two later? Well, it turns out there are reasons for this.

Study: half of the studies you read about in the news are wrong

It turns out that reporters tend to report on initial studies, which are more likely to be contradicted in one or more ways later on. In the world of science, inital studies are just that: initial.

Besides the attention grabbing headline, this article has a good critique of the reasons why initial studies tend to be reported instead of the later metareviews which are more likely to be correct.

This is a real problem. People learn about science mainly through the media, and if it feels like everything reported turns out to be wrong, people start distrusting science. If reporters were more careful to publicize the later, more complete studies, people might develop more faith in science. I think reporters, too, should spend more time explaining the process of science to their readers, rather than just pushing out headlines and brief explanations of what may be very small and very tentative studies.

Good science and financial reporters are in terribly short supply, And given the fragile state of the field of journalism these days, I don’t see it improving. But these are two areas that impact everyone. People have to make decisions about both science and financial information all the time, including when they vote. How can we improve public understanding?
