Broad topics or specific topics? How much the thesis should cover

Maybe you have the intention of doing a thesis that deals with many subjects, so let me tell you that this is a very bad idea. You will not achieve it, even if you try with all your will, in the best case you would only achieve a half-thesis, very vague and unwise.

Doing a thesis that speaks of many things is not only risky, but almost impossible. Even the most expert investigators would not dare commit such awkwardness.

Unlike what one might think, research goes from the general to the particular. The acquisition or production of scientific knowledge is not to investigate everything, otherwise, investigate something specifically to deepen a topic.

If we look, the levels of study, undergraduate, masters and doctorate, consist of specializations that give the student an advanced knowledge in a very particular area. Then, it is necessary to be more modest with the topic of the thesis and choose something more concrete. Also, if you do, your work will be much easier to handle and, later, defend.


Creating a thesis is a way to become an expert in a subject and to achieve it you have to control very well the scope and delimitations of your research. The narrower your theme is, the more likely you are to emerge triumphant in defense. It is probable that the jury does not know in depth a subject that is very delimited, so they will question your work less.

Being a retailer will facilitate the development of your thesis, but that does not mean that the research should be brief or superficial. It is necessary to deepen enough in the subject, but it is better to deepen in a single subject and not in several. Restrict will allow you to clearly know where to go and where not, your readers will tell you what you are going to talk about and what not.

It may seem a bit boring or tedious to dedicate so much effort and time to one thing, but that does not exclude that you can investigate other topics related to yours to give a context. However, they will not be the foundation of your work.

Keep in mind that when the time comes to evaluate your thesis, the first thing the jury will do is verify the relevance and basis of your statements. A loose end can lead to failure all your research and throw down what so many eyelashes have cost you. The more you delimit your subject, the better you can say everything that should be said about the subject, with less risk of forgetting something or treating it very briefly.


If it is a thesis of analysis of historical analysis, up to a period of one year can mean a lot of time. It is the most detailed, for example: It is not the same to study “The lyrical in the fourteenth century of the Middle Ages”, that “Castilian lyric in the fourteenth century of the Middle Ages,” is even better “The study of lyric Castilian in the fourteenth century of the Middle Ages: The case of Juan de Mena. In any case, the third title is preferable.

A good datum, the shorter the title, the more likely the subject is to be less specific and if you decide to do comparative theses, use only two or three authors. Do not choose subjects where you have to treat several authors to create the theoretical framework, nor do field studies with very extensive data collections and many variables. Finally, do not forget to check with your teachers, colleagues and study partners.
