What makes a good controversial essay topic?

A good controversial topic is genuinely debatable, with strong, reasonable arguments on both sides, so there is a real debate to engage with rather than an obvious answer. It should be one you can argue with evidence, not just strong feeling, and specific enough to argue thoroughly in the length you have. It is also worth choosing a topic you can discuss maturely and fairly, since the best controversial essays engage respectfully with views they disagree with. Avoid topics so inflammatory that reasoned argument becomes difficult, and favour those where evidence, not just emotion, can carry the case.

How to argue a controversial topic well

Arguing a controversial topic well means arguing with evidence and reason, not emotion. Take a clear position, support each point with credible evidence, and, crucially, engage fairly with the opposing view before refuting it, which our guide on a rebuttal in an argumentative essay covers. Because these topics provoke strong feelings, a calm, reasoned tone is more persuasive than an emotive one, and it shows the maturity markers reward. Acknowledging the strongest arguments against your view, and answering them, is what makes a controversial essay convincing rather than one-sided, so treat the other side with respect even as you argue against it.

Tips for a strong controversial essay

Choose a topic you can argue maturely and support with evidence, take a clear position, and structure your essay around your strongest points.
