What should a thesis statement include?

A thesis statement serves as the foundation for a paper, outlining the main argument and key points that will be discussed throughout the text. It is a concise summary that indicates the direction of the paper, presenting the primary claim the author intends to support with evidence and analysis. This clarity helps readers understand the purpose and scope of the work while guiding the author in organizing their thoughts and arguments effectively.

In contrast, an extensive review of existing literature is more appropriate for the body of the paper rather than a thesis statement, which should remain succinct and focused on the main argument. Similarly, a summary of the conclusion would not be suitable for a thesis statement, as it should be placed at the end of the paper instead of introducing its key points. Lastly, while personal opinion might be relevant in some contexts, a thesis statement is best when it articulates an argument that is backed by research and evidence, rather than just expressing personal beliefs.
