The thesis statement should talk about the main idea that you are going to present in your essay. The most important factor about writing a thesis statement is that it should be specific. One common mistake that many people do while writing it, is making a general statement about what they are going to write in the essay. For instance, if you are writing about capital punishment, your thesis statement should not be something like the following.
► Capital punishment is not the appropriate way of punishing a person for a crime he has committed.
This is an example of a weak thesis statement because it is too generic as well as vague. The reader may understand the stance you have taken, but not the reason behind it. Hence, it is important that you write down the reason behind the statement. To make the thesis statement more specific, you can ask yourself why you think it is bad, which will generate an answer that will help in making your thesis statement more specific. For instance,
► Humans do not have the right to take away the life of other humans, hence capital punishment is not the correct way of punishing a criminal.
