We all get numerous messages which are fake on WhatsApp and forward it without giving it too much thought. Thejesh GN has written on his blog about these forwards, with suggestions on how WhatsApp could handle fake news.
It is important that you verify things you hear on WhatsApp from another primary source. If you trust the person sending you the forward, do question if he/she thinks the news is true or not. I would suggest using Google News and to visit a news publication you trust or visit the organisation/individual’s website.
