You can find articles testifying that all three of the previous claims are true; however, when you dig deeper, it’s clear that they’re not. Just because you find one article stating that something is true, that does not necessarily mean it is a proven fact that you can use in your research.
Any information that doesn’t fit within the framework of your outline, and doesn’t directly support your thesis statement, no matter how interesting, doesn’t belong in your research paper. Keep your focus narrow and avoid the kitchen sink approach.
If you want to find helpful and reliable sources of information, the library is literally the best place to look around. There are numerous books, published articles, journals and etc. that you can choose from about your chosen topic.
Working with your teacher and asking them for help is an often overlooked resource when it comes to writing research papers. Be sure to take advantage of this help; your paper will be all the better for it.
So you have all of this information, now what to do with it? Step four is all about getting organized. Like research, different people have different preferences here. It can also depend on your assignment. Some sort of bibliography (literally “book writing,” this is a list of the books, articles, and other sources you have used in your research) is helpful when it comes to organizing your research.
