Character comparison is one of the most common assignments for any long novel, and Cryptonomicon offers plenty of material, from the mathematician Lawrence Waterhouse to the Marine Bobby Shaftoe to the modern-day Randy Waterhouse. These essays are popular with students because the structure feels familiar. They are also prone to listing traits without making an argument about what the contrast means.

The first thing to check is whether the comparison has a purpose. A strong paper uses the contrast between two characters to say something about the novel, such as how it values different kinds of intelligence or courage. A weak paper says that one man is analytical and the other is physical and then stops.

Graders can push this distinction in the assignment itself by requiring a claim that begins with the word because or so that. A thesis built that way forces the writer to connect the comparison to a larger point, which makes the resulting paper far easier to evaluate.

Evaluating Evidence for Character Claims

Evidence in character essays should show behavior, not just labels. Saying that Lawrence is brilliant is a trait, while describing how he approaches a problem during wartime work and what that reveals about his priorities is evidence. Look for scenes in which characters make choices, since choices reveal values more clearly than descriptions do.

• Specific scenes in which each character makes a meaningful decision
• Quotations or paraphrases that are explained rather than dropped in
• A balance of attention so one character does not dominate the paper
• Acknowledgment of ways the characters overlap, not just differ
• A conclusion that says what the contrast reveals about the novel

Avoiding Common Scoring Pitfalls

Graders sometimes reward essays that sound confident and well organized even when the character analysis is shallow. A tidy block structure with two paragraphs per character can hide a lack of interpretation. Look past the formatting and ask whether any sentence actually explains why the characters matter to the book.

Another pitfall is punishing unconventional pairings. A student who compares Lawrence to Randy across eras may produce a more interesting argument than one who compares two characters in the same timeline. The rubric should leave room for creative choices as long as the evidence supports them.

Feedback That Deepens Comparisons

One effective comment asks for an unexpected similarity. If a student argues that two characters are opposites, prompting them to find where the two behave alike often leads to a more complex thesis. It also teaches students that good comparisons usually include tension, not just contrast.

Encourage students to organize by idea rather than by character. A paragraph focused on how each man handles secrecy, for instance, naturally compares them within a single section. This pattern tends to produce stronger analysis and is simpler for graders to follow.

Making Comparisons Efficient to Grade

A one-page scoring guide with three or four questions can keep grading consistent. Does the thesis explain why the comparison matters, does each paragraph discuss both characters, and is the evidence behavioral? Quick yes or no answers help calibrate the final score.

For large classes, an AI grading assistant can draft rubric-aligned comments and highlight where the paper lacks a purpose for the comparison. Teachers still review and revise the comments before returning them. This approach saves time while preserving the personal tone that students value.
