An encyclopaedia with rather low standards that many people sadly treat as an absolute source of truth.
You're right that this isn't really a wikipedia problem though. It's a matter of education because an overwhelming majority of the population isn't competent enough to fact-check memes on facebook, let alone wikipedia, and if wikipedia doesn't do it either, then that responsibility is pushed all the way back to the scientists doing the actual research.
This is an incredible lack of redundancy if you consider how important wikipedia has become in shaping public opinion. It's a system where the scientific publication process is the single point of failure and this article clearly shows that it does fail rather often.
So what way is there to make this process safer? There needs to be at least another link in the chain that confirms information, preferably two or three.
