And here I am fixing missing sources on some wiki articles just yesterday.

I feel like news sources used to link to their sources too, but now it seems to be an infinite chain of links to their own articles, never directly taking you to the first hand source of information (unless they are the source).

The thing is, if the place you're getting your information from doesn't list it's sources, you can't trust it. Whenever I'm researching a thing on the internet and I find an article or a paper, I don't just stop there, I check where they got their info, then I find that source and read it. I follow it all the way back until I find the primary source.

Like the other day I was writing a paper about a particular court case. In the opinions, as in most cases, they use precedent and cite prior cases. So I found the other cases that referred to the thing I was writing about, and it turns out they were also just using prior cases. I had to go 6 deep before I found them referencing the actual constitution for one of them. On another I found it interesting that the most recent use case was so far removed from what the original one was about and it was could probably be questionable to even use it as precedent if they had used the original instead of another case.

Anyway, the point is, always check sources. If anyone says anything on the internet, assume it's just their opinion until you check and follow the sources..

And very often it's dead links or sources that don't say what the article pretends...
