You can start by checking reliable news sources. Established media outlets with a good reputation often provide accurate information to help you distinguish the truth.
Another way is to cross-reference multiple sources. If different trustworthy sources report the same thing, it's more likely to be true. Also, look for verified facts and data to support the claims in the news.
You could try fact-checking websites. They specialize in verifying and debunking fake news. And be cautious of news that seems too sensational or without proper attribution.
