Bias is a preconceived inclination or preference for or against an idea, person, place, etc.
Identifying bias is complicated because it can be subtle. It also exists on a spectrum making it more nuanced. There is no quick and easy way to ensure that you will identify bias in a source. The best way to identify bias is through careful evaluation. However, it's also important to remember that as a researcher, your reading of sources is done through the lens of your own biases.
Bias can be conscious or unconscious. It can influence our actions in in obvious or subtle ways.
