Churnalism.
More than a decade ago I saw a story about what happened to a "Swiss National" who was jailed in the UAE for three poppy seeds on their shirt. It was quite a disturbing story and was reported around the time some more high profile cases of people being arrested in UAE for what would be normal things in western countries. I saw the same story with the same language appear in dozens of news sites I read and then got suspicious that the wording was near identical and the individual never named.
search for "swiss national jailed UAE poppy seeds" and you can still see some of the articles
Anyway, I contacted the NGO (who it seems does good work, btw!) and asked who this person was and what happened to them. I got a response that during an interview about a more prominent case they told one journalist that it was just a rumour they heard and the story snowballed from there. Nobody contacted them to get more details.
The point I took is not that anyone is malicious or has some sinister agenda but that budgets in newsrooms had been so cut to the bone and "content" needed to be produced as fast as possible to get the clicks, to churn out those stores, and get that ad revenue that nobody had time to do basic fact checking. They were incentivised by the system not to.
