What is a one-sentence summary of the following article?
A thesis statement should be an arguable idea, meaning that someone could potentially hold and argue the opposing view.  For example, the following thesis statement is weak because it just states a fact: “Exercising is good for you.” This kind of thesis statement leads to an uninteresting, underdeveloped paper.  It is a proven fact that exercise is good for you and no one would legitimately argue against that. Writing a thesis is tricky business. You must give enough background information to guide your reader, but not overshare and provide too much material in your introduction. A broad thesis statement makes claims that are ambiguous, vague, or overreaching. They attempt to address too many topics for the assignment and don’t have a clear focus. A narrow thesis statement is too single-minded or specific to use in crafting a well-developed essay.  An example of a broad thesis statement is, “Sigmund Freud is one of the greatest psychologists in medical history.” This thesis statement is too broad because it is too general/vague and could discuss almost anything. It doesn’t tell you where the paper will go, what the main idea is, or any support for this claim.  An example of a narrow thesis statement is, “Sigmund Freud’s theories on dream interpretation single-handedly changed the evolution of psychoanalysis.” This thesis statement is too narrow because it only allows for one viewpoint (that Freud was the only influence on psychoanalysis), which will lead to an essay that ignores a lot of evidence (other influences on psychoanalysis). Generalizing, especially in thesis statements, is dangerous because it attempts to summarize all of the paper’s content into one lump sum idea while omitting any of the supporting details. These kinds of statements are weak because they make a claim that is not backed up by evidence. Statements that generalize tend to start with a phrase like:  “What it all boils down to is…” “What this adds up to is…”

Summary:
Refrain from simply stating facts. Find the line between too broad and too narrow. Don’t generalize.
