Common Problems

First, look through this list of common mistakes made when writing thesis statements.

To summarise, the major errors tend to be that:-
  1. The thesis statement consists of an empty observation, rather than making an assertion.
    • INSTEAD OF: Industrial emissions contribute to global warming.
    • WRITE: Of all the factors that contribute to global warming, industrial emissions are considered the most significant, and national governments should be forced to regulate their carbon-dioxide levels by means of multilateral treaties.
  2. The thesis statement is underdeveloped and vague, and needs to be made more specific and narrow.
    • INSTEAD OF: The enlargement of the EU has led to considerable debate.
    • WRITE: The expansion of the EU to include 10 new member states has sparked considerable debate concerning the issues of subsidies, constitutional unity and the limits of integration.
  3. The thesis statement exceeds the scope of the essay, i.e., is too broad to be discussed thoroughly.
    • INSTEAD OF: There have been many cases of human rights violations in the recent past.
    • WRITE: Recent developments in Western, democratic societies such as anti-terrorism legislation, which allows imprisonment without trial, have highlighted to human rights activists that, even here, their work is far from complete.
  4. The thesis statement is too detailed or wordy. The arguments should be summarised in the introduction and developed in subsequent paragraphs.
    • INSTEAD OF: Communication is the most important aspect of language learning, as learners only learn to use expressions and grammatical constructions correctly when they communicate and use these constructions actively. A practical understanding of a wide range of expression can only be attained by means of communication, never by methodically learning of grammar.
    • WRITE: Recent studies show that, whilst grammar should not be neglected in a foreign language syllabus, it plays a far less significant role in developing the language skills of the avarage learner than active communication.
  5. The thesis statement introduces several unrelated points, rather than the main points of the argument.
    • INSTEAD OF: With societies becoming increasingly diverse, the question of how to integrate immigrant populations is becoming increasingly urgent, and we are also being confronted with an increasing number of different cultures and lifestyles.
    • WRITE: With societies becoming increasingly diverse, questions concerning integration and assimilation, and the extent to which the culture of the host country should take precedence over that of the immigrant, are provoking increasing debate.
