General practitioner, medical researcher, and founder of PrimeHealth Clinical Research, Iris Gorfinkel, M.D., told Bored Panda that social media and the Internet are not a one-size-fits-all. "On the one hand, it improves patient education and can improve public health. It brings people together who are in very wide apart places, so it overcomes geographical barriers... It's a tremendous educational tool for patients," Gorfinkel said.

Yes, it promotes awareness and encourages patient engagement, and it can provide quality information. But at the same time, people are searching online for the next big thing. "So what is more likely to be shared?", the doctor asked metaphorically. What is novel, she immediately answered. Or what is unusual.

Gorfinkel also pointed out a study done in 2018, published in Science by three MIT scholars, which found that falsehoods are 70% more likely to be retweeted on Twitter than truth. It also discovered that it took the truth about six times as long as falsehood to reach 1,500 people. This proves that falsehoods are simply alluring.

But even if many of us know not to trust what uncle Bobby is saying about vaccines on his Facebook page (I hope), reading a scientific paper can be really challenging and time-consuming. "I think there are some websites that are fairly trusted," Gorfinkel said. "Medscape, for example, tries to bring information to people in their own language. It's not perfect, but it is available in German, Portuguese, Spanish, and French. Then there's WebMD, MedlinePlus, Drugs.com. There's a whole bunch of these websites that are actually quite good."

For the so-called orphan conditions — diseases that are so rare, there isn't enough resources on them — Gorfinkel suggested Orpha.net.

If you are still concerned about the validity of a certain piece, you will probably have to inspect it yourself.

What is to stop any doctor or professor from writing an opinion piece? Nothing, but this is where peer reviews come into play. "That's where other doctors and professors who have nothing to gain from what's published, look at the paper and say, 'Yes, this is actually true.' So look for things that are peer-reviewed, look for at least an editorial board. Again, that's a safeguard to prevent any one person's opinion from becoming a fact because peer reviews and editorial boards keep doctors in line in terms of making sure that what is said is accurate," Gorfinkel explained.

The sources that Gorfinkel mentioned earlier, like WebMD, publish some research studies that require huge funding. So looking at the funding source matters too — is there a conflict of interest?

Of course, when a particular paper was written is important as well because, as Gorfinkel highlighted, what may have been relevant, say for COVID-19, even in 2020 is, for the most part, not relevant at all in 2021.

Generally, when you notice medical information online, it's probably best to approach it with caution. "If there is a promise of a miracle cure, that should ring alarm bells big time," Gorfinkel said. "A lot of complex problems, including depression, anxiety, hair loss, acne; a lot of these problems are actually complicated, and they don't have one single solution. This is especially true when things promise very quick answers, and often at a price."

It's always a good idea to run these ideas by either your family doctor or a pharmacist before investing in them.
