There are a few small steps you can take to fight fake news:
Don't click on fake news, as it's being spread for financial gain, so the fewer people who look at it and share it, the less worthwhile it is to produce such articles.
Critical thinking is one of the most important ways to identify fake news. We must not believe everything we see, even if it seems true.
Our brains are often fooled by this fake news in such a way that even to a skilled reader what they see seems believable, due to errors in reasoning and psychological manipulation.
