it's difficult, but possible. it is best to take some articles that offer a choice from several sources. something like charts because then there is an alternative. if we talk about private chat rooms it's found on the forums like this
I'm still not convinced you hadn't been told about the sources of information before you actually sat down and searched for the articles. At the end of the day, I prefer statistics over articles since they don't show opinions but plain numbers instead.
Do not forget that Google is only an instrument and on the first page those who want to be there. SEO etc. And it is enough to find one source to find others, since everything is connected. Google is the first step when you are studying something, that's all.
