I know, it sounds strange: you just ignore the specifics and take the general concepts, Google them and go to reputable sites that cover the specifics of the subject.
To illustrate, take numbers: some sites might cover 1. Some cover 4 but the 1 sites might not reference the 4 sites, and visa versa.
If you go to Wiki, it might say the first five numbers are 1 4 3 2 5. If you assume that's wrong but you start Googling the other numbers, you're going to find a reputable site that states the numbers are 1 2 3 4 5. If you hadn't gone to Wiki, you might not have ever known about 2 3 or 5.
It's a bizarre way to do research, but it works. lol.
Of course you'll run into Wikstera who edit the article thusly: "controversial allegations of the numbers being 1 2 3 4 5 have been made by President Bush. Critics claim that this numbering system is highly suspect and somehow benefits the Republican administration. Scientists and Nobel laureates have remained by the 14325 numbering system."
