There are a few things to look for when looking for a debatable topic. Is this topic able to be backed by facts on both sides? Is your paper more than opinions? Is this a current or old subject? All of these are important when choosing what to write about. The above topics are all in this guideline. For example, should gay marriage be allowed? This is something that can be argued on both sides because you can say yes or no. It can be backed by facts because it is a legal issue, and it is a recent ongoing topic in the news. Another example, has social media invaded privacy rights? This can be answered yes or no, can be backed by researching on privacy rights and media rights, and also is ongoing in the news with celebrities. They are all great debatable subjects, because they meet the guidelines. Now you too can write more effectively on debatable subjects.
