I understand the thrust of your comment and generally agree with your broad sentiment. But, most scientific studies present a model that fits data. While you are right that they can show a truth, that is not their aim, and often they are contradicted with newer data and models. Studies are only valuable when they form a scientific consensus over repeated experiments or provide some predictive power that can be confirmed through other experiments. To use a studies as a prescriptive guide to base your life on, or change of habits is an error IMHO, and ironically, quite unscientific. I guess you could say its a pet peeve of mine. 9 times out of 10 when I investigate a "studies have shown" comment, it turns out to be half-true or based on weak science, or too new to be replicated by other scientists, or sometimes the context is completely different from its use in an argument.
