This'll is John John wants to write a Wikipedia article about the beginning of the universe.

He knows that the popular encyclopedia is the work of thousands of volunteer authors.

Everyone can contribute.

But what does that mean for John's article?

Many people have many opinions.

Political and religious topics often lead to conflict to make sure that Wikipedia's content is trustworthy, all articles air written from a neutral point of view.

Because John knows how many discussions there are about this topic, he lists various theories about it to guarantee neutrality.

He doesn't indicate which one he believes and which ones he rejects.

John stays neutral so that each reader can form their own opinion to uphold the credibility of Wikipedia and his article.

John shows everyone exactly where his knowledge comes from.

So if he writes that his neighbor Ana has been on the moon, he needs to prove that with a good source, good sources include respected technical books, academic publications or well researched press articles.

Online sources can be used as well, of course, but especially in that case, the source must be trustworthy.

For that reason, John doesn't rely on Anna's personal blawg, where she presumably doesn't report on events from a neutral point of view.

Also, John doesn't site any other Wikipedia articles in his own Wikipedia article because, well, it's a vicious circle.

Also, John links to Hiss sources for everyone who wants to read more about the topic.

Also that way, every reader can decide for themselves how reliable the sources, by the way, facts that are widely established, such as that the Earth is round okay and oblate spheroid don't require citations from John.
