When you read an argument, you should approach it with a critical eye. Contrary to what you may think, reading critically does not mean arguing with every idea you encounter. What it does mean is commenting on, questioning, and evaluating these ideas.
As a critical reader, you do not simply accept that what you are reading is true. Instead, you assess the accuracy of the facts in your sources, and you consider whether opinions are convincingly supported by evidence. You try to judge the appropriateness and reliability of a writer’s sources, and you evaluate the scope and depth of the evidence and the relevance of that evidence to the topic. You also consider opposing arguments carefully, weighing them against the arguments developed in your sources. Finally, you watch out for possible bias in your sources—and you work hard to keep your own biases in check.
