SOURCE RELIABILITY – INFORMATIONAL TEXTS

When analyzing arguments on the GED® test, a key question is:
Is the information presented accurate and trustworthy?
To answer this, you must evaluate whether the source of the information is reliable.

What Makes a Source Reliable?

A reliable source presents accurate, well-supported, and objective information. These sources often include:

• Scholarly journals
• Academic textbooks
• Government documents
• Articles written and reviewed by subject-matter experts

In contrast, information from random websites, opinion-based blogs, or unverified commentary may lack accuracy or objectivity.

Understanding Bias

Bias refers to a tendency to favor one perspective or side. Even primary sources—such as personal letters, speeches, or eyewitness accounts—can include bias. While these sources provide direct insight into events, they may reflect the personal views or limitations of the writer.
Being able to detect bias is critical for assessing the reliability of any source.

Practice Example: The Battle of Lexington and Concord

Question: Which of the following is the most reliable source of factual information about the battle?

A. A scholarly article published in an academic journal
B. A letter written by British General Thomas Gage to King George III
C. A website featuring commentary from amateur history enthusiasts
D. A poem written by an American decades after the battle

Correct Answer: A
Scholarly articles in academic journals are reviewed by experts and must meet high standards for accuracy. These sources are considered reliable for presenting factual historical information.
