When we begin a research assignment with a formed opinion or argument in mind, it can be difficult to avoid bias in our writing. The choices we make when we look for information can be biased too. Looking for sources that support your thesis is an example of confirmation bias, and confirmation bias is, "a tendency to look first for information that confirms a desired conclusion" (Cornell Law School).

How can you avoid bias? Try starting with a question. Or, if your professor asks you to start with a thesis, try turning it into a research question for your own use. Begin with the question, and let the evidence guide you to a thesis. As you read and take notes, your research question will likely develop into a thesis and should become more detailed as you find more information. Your thesis may even change. Be sure to create it based on strong evidence from a variety of sources and voices.

Examples of strong research questions:

• What factors led to the WorldCom collapse?
  • Example thesis = A, B, and C were the most influential factors in WorldCom's collapse.
• To what extent is America perceived by social critics to be in decline?
  • Example thesis = High school science education in the United States is perceived to be in major decline because A, B, and C.
• How has the debate over genetic engineering evolved during the past decade?
  • Example thesis = In recent years, biased news creators have significantly influenced the public's perception of genetically modified plants and foods in these ways...
• To what extent do contemporary diet ads perpetuate sexist attitudes?
• How do contemporary cigarette ads differ in message and tone from cigarette ads in the 1950s?
