Many of us trust whatever we hear. Many do not. Some people trust with evidence. Some people don't trust even with it.
There are many reasons that we either do or don't trust. This can include knowing the author, the article being from a genuine source or prior knowledge of the source. Trust is generally used in the case of the news, as well as in real life. Youtube is a media known for fake news spreading around it, mainly in the form of clickbait.
Clickbait: Advertising a video so that the audience will want to watch it, and where the advertised event never happens.
Many newspapers are also known for selling fake news, and even make their entire profits off of it. Some people may not realise that these media outlets are known for selling fake news, and may spread 'gossip', based off of the news they read. Places like Instagram are also known for selling fake news, most usually by verified influencers, who get paid for advertising products. Since these come from users with the 'big blue tick' next to their username, they are more likely to be believeable. This is also true for media platforms such as Snapchat and Twitter.
So, what makes you trust?
