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 aren’t familiar with what a research paper is, let me give you’re a rundown of the definition: a research paper is a form of academic writing that has theoretical and substantial information that has gone through the proper process of in-depth research. It could contain arguments based on a thesis with significant evidence from a variety of supporting and reliable sources.
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.
The good news is, once you reach this point in the process you’re likely to feel energized by all the ideas and thoughts you’ve uncovered in your research, and you’ll have a clear direction because you’ve taken the time to create a thesis statement and organize your presentation with an outline.
Finally, don’t ignore information. You can find an article that says anything you want it to say. Did researchers recently discover that octopus DNA is made of alien DNA from outer space? Are the spires on the Cinderella Castle at Disney World removable in case of a hurricane? Did a cook attempt to assassinate George Washington by feeding him poisoned tomatoes?
