Some pseudoscience is pretty obvious. I think most of us are comfortable saying that the world will probably not end this December, in accordance with any ancient prophecy. But distinguishing fact from fiction isn't always simple. In fact, "fact from fiction" might be too simple a way to even frame the question. In reality, we're sometimes tasked with spotting misapplication of real science. Sometimes, we have to tell the difference between a complicated thing that nobody understands yet very well but which is likely to be true and a complicated thing that nobody understands yet very well but which is not likely to be true.
Basically, it's messy.
Emily Willingham at Forbes has some helpful hints for how to make these distinctions. She offers ten questions that can serve as guidelines for approaching new topics you're skeptical of — questions that, taken all together, can help you see the patterns of pseudoscience and make informed decisions for yourself and your family.
3. What kind of language does it use? Does it use emotion words or a lot of exclamation points or language that sounds highly technical (amino acids! enzymes! nucleic acids!) or jargon-y but that is really meaningless in the therapeutic or scientific sense? If you're not sure, take a term and google it, or ask a scientist if you can find one. Sometimes, an amino acid is just an amino acid. Be on the lookout for sciencey-ness. As Albert Einstein once pointed out, if you can't explain something simply, you don't understand it well. If peddlers feel that they have to toss in a bunch of jargony science terms to make you think they're the real thing, they probably don't know what they're talking about, either.
9. Were real scientific processes involved? Evidence-based interventions generally go through many steps of a scientific process before they come into common use. Going through these steps includes performing basic research using tests in cells and in animals, clinical research with patients/volunteers in several heavily regulated phases, peer-review at each step of the way, and a trail of published research papers. Is there evidence that the product or intervention on offer has been tested scientifically, with results published in scientific journals? Or is it just sciencey-ness espoused by people without benefit of expert review of any kind?
