Understanding Historical Bias and Inquiry Methods

Study Tip: When analyzing a source, don't just ask "Is this true?" Ask "What is this source trying to make me believe, and why might they want me to believe it?"

The Toolkit of Historical Inquiry

To move beyond the surface level of a document, historians use a specific set of inquiry methods. These tools allow us to peel back the layers of bias and find the most accurate version of events.

1. Sourcing: Investigating the Origin

Sourcing is the first step in the inquiry process. Before you even read the content of a document, you must examine its "metadata." Sourcing involves asking critical questions about the origin of the piece:

• Who created this? (Author, organization, or group)
• When was it created? (Is it a primary source from the time of the event, or a secondary source written much later?)
• Where was it created? (The geographic and political setting)
• Why was it created? (The purpose: to inform, to persuade, to entertain, or to record?)

By identifying the author's identity and purpose, you can begin to predict where their biases might lie. A diary entry from a soldier provides a very different type of information than an official government decree issued by the same army.

2. Contextualization: Setting the Scene

Contextualization is the process of placing a source within its specific time and place. A document cannot be understood in a vacuum; it is a product of its environment. To contextualize effectively, you must consider the social, political, economic, and cultural circumstances surrounding the creation of the source.

For example, if you are reading a political speech from 1940, you cannot understand its urgency or its rhetoric without understanding the global state of World War II at that exact moment. Contextualization helps you understand why certain ideas were considered "normal" or "radical" at the time, preventing us from applying modern-day values to historical figures—a mistake known as presentism.

3. Corroboration: Seeking Consensus

Corroboration is perhaps the most vital step in ensuring accuracy. It is the act of comparing multiple sources to see where they agree and where they disagree. If three different accounts from three different people describe the same event in the same way, the level of historical certainty increases.

However, corroboration is not just about finding agreement. Disagreements are often just as informative as consensus. If two sources describe the same event differently, the discrepancy itself becomes a subject of inquiry. Why do they disagree? Does one source have access to information the other lacks? Does one source have a stronger motive to distort the truth?

Putting It All Together: A Worked Example

Imagine you are researching a local labor strike that occurred in 1920. You find three different sources:

1. A newspaper article from the local paper, which is owned by a factory mogul.
2. A personal letter from a factory worker to their family.
3. A police report regarding the arrests made during the strike.

If you only read the newspaper article, you might conclude the strike was a violent riot caused by "unruly agitators" (Selection and Tone Bias).

By applying sourcing, you realize the newspaper owner has a financial interest in seeing the strike fail. By applying contextualization, you remember that 1920 was a period of intense labor unrest and rising inflation. By applying corroboration, you read the worker's letter, which describes the strike as a peaceful protest for fair wages, and the police report, which notes that the "unruly" behavior actually began after police moved in to break up a peaceful gathering.

Through these methods, you move from a one-sided, biased view to a complex, accurate understanding of the event.

Exam Tip: In essay questions, never rely on a single piece of evidence. Always use phrases like "This is corroborated by..." or "While Source A suggests X, the context provided by Source B indicates Y..." to demonstrate your mastery of inquiry methods.
