To avoid confirmation bias in searches: Avoid asking questions that imply a certain answer. If I ask “Did the Holocaust happen?,” for example, I am implying that it is likely that the Holocaust was faked. If you want information on the Holocaust, sometimes it’s better just to start with a simple noun search, e.g. “Holocaust,” and read summaries that show how we know what happened. Avoid using terms that imply a certain answer. As an example, if you query “Women 72 cents on the dollar” you’ll likely get articles that tell you women make 72 cents on the dollar. But is you search for “Women 80 cents on the dollar” you’ll get articles that say women make 80 cents on the dollar. Searching for general articles on the “wage gap” might be a better choice. Avoid culturally loaded terms. As an example, the term “black-on-white crime” is term used by white supremacist groups, but is not a term generally used by sociologists. As such, if you put that term into the Google search bar, you are going to get some sites that will carry the perspective of white supremacist sites, and be lousy sources of serious sociological analysis. Plan to reformulate. Think carefully about what constitutes an authoritative source before you search. Once you search you’ll find you have an irrepressible urge to click into the top results. If you can, think of what sorts of sources and information you would like to see in the results before you search. If you don’t see those in the results, fight the impulse to click on forward, and reformulate your search. Scan results for better terms. Maybe your first question about whether the holocaust happened turned up a lousy result set in general but did pop up a Wikipedia article on Holocaust denialism. Use that term to make a better search for what you actually want to know.
The art of asking the right question applies to research as well as surveys. If you ask the question the right way, you will be more likely to get the answers you want. This is another area of web literacy as well as critical thinking: should I trust the results of any given survey?
