Whether you are assigned a general issue to investigate, given a list of problems to study, or you have to identify your own topic to investigate, it is important that the scope of the research problem underpinning your study is not too broad, otherwise, it will be very difficult to adequately address the problem in the space and time allowed. You could experience a number of problems if your topic is too broad, including:

A common challenge when beginning to write a research paper is determining how to narrow down your topic. Even if your professor gives you a specific topic to study, it will almost never be so specific that you won’t have to narrow it down at least to some degree [besides, it is very boring to grade fifty papers that are all about the exact same thing!].
A topic is too broad to be manageable when you find that you have too many different, and oftentimes conflicting or only remotely related, ideas about how to investigate the research problem. Although you will want to start the writing process by considering a variety of different approaches to studying the research problem, you will need to narrow the focus of your investigation at some point early in the writing process. This way, you don't attempt to do too much in one paper.
Here are some strategies to help narrow your topic:
NOTE: Apply one of the above strategies first in designing your study to determine if that gives you a manageable research problem to investigate. You will know if the problem is manageable by reviewing the literature on this more specific problem and assessing whether prior research on the narrower topic is sufficient to move forward in your study [i.e., not too much, not too little]. Be careful, however, because combining multiple strategies risks creating the opposite problem--your problem becomes too narrowly defined and you can't locate enough research or data to support your study.
