Second thoughts should probe quite a bit more deeply. Thinking about what the
author is trying to say, considering who he or she was addressing in the first place,
identifying the gap the article has been written to fill and asking other such questions
is the foundation for the critical evaluation of the article. Even if you didn’t
know anything about the topic before you read the article, you can make some
judgements about it and how well the author made her or his case.
