Write an argument that anticipates an audience’s knowledge, concerns, values and possible biases while weighing claims and counterclaims

Learning goal: Write arguments to support claims in an analysis of substantive topics or texts, using valid reasoning and relevant and sufficient evidence. Establish a clear and thorough thesis that presents a complex argument; introduce precise, knowledgeable claims and establish their significance; distinguish them from alternate or opposing claims; organize so that claims, counterclaims, reasons and evidence follow a logical sequence; develop claims and counterclaims fairly and thoroughly, supplying the most relevant evidence for each and pointing out the strengths and limitations of both in a manner that anticipates the audience's knowledge level, concerns, values and possible biases; link major sections with words, phrases, clauses and varied syntax; keep a formal style and objective tone suited to the discipline; and conclude in a way that follows from and supports the argument.

The scenario this unit uses. Castlemere Regional Library is invented, and so is every number attached to it. Its board is deciding whether to stop charging overdue fines. The simulated sources are these. Budget sheet (audited): the system has 9 branches, 62,000 active cardholders and an annual budget of 8,000,000 dollars; fines brought in 48,000 dollars last year, which is 0.6 percent of the budget. Finance office estimate: staff time spent collecting and recording fines cost about 21,000 dollars, an estimate built from average minutes per transaction multiplied by wages, not from a time study. Circulation report: 7,400 of the 62,000 cards, about 12 percent, are blocked because the holder owes 10 dollars or more, and 4,440 of those 7,400 blocked cards, 60 percent, belong to cardholders under 18. Pilot report: two branches went fine-free for 12 months; their on-time return rate was 91 percent in the year before and 89 percent during the pilot, and 310 of their 820 blocked cards, about 38 percent, were reactivated. Staff survey: 54 of 80 staff responded; 36 favor ending fines, 12 oppose and 6 are unsure. Public comments: 212 comments were submitted; 131 favor ending fines and 81 oppose. Dunmore report: another invented library went fine-free and saw circulation rise 6 percent in the same year it added Sunday hours. None of this describes a real library, and the evidence supports more than one reasonable position.

What grades 11-12 add. At grades 9-10 a writer weighed the strengths and limitations of the evidence on both sides. At grades 11-12 three further demands arrive. The thesis must present a complex argument, which means it holds more than one consideration in tension instead of stating a single preference. The claims must be knowledgeable and their significance established: the reader should see why the question matters and that the writer understands it better than a casual observer. And the weighing of both sides must anticipate the audience's values and possible biases, not only what they know and what worries them.

Knowledge, concerns, values and biases are four different things. Knowledge is what the audience already understands; a library board knows its budget but may not know how the finance office built its estimate. Concerns are what they fear will happen; board members fear lost revenue and unreturned books. Values are the principles they use to judge any outcome; one member may value responsibility (people who borrow shared property should bear a cost for keeping it), another access (a public library exists so that anyone can read). Biases are tendencies that tilt judgment before the evidence is weighed; a board that has always charged fines may treat the current system as neutral and any change as the risky option, which is a status-quo bias. A writer who addresses only knowledge and concerns can still lose a reader whose values are untouched. Anticipating a value means showing how the claim serves it, or honestly stating the trade-off. Anticipating a bias means naming it gently and giving the reader a way past it, never accusing the reader of it.

A clear and thorough thesis for a complex argument. "Castlemere should end fines" is a claim, not a thesis for a complex argument. A thorough thesis holds the tension: "Castlemere should end overdue fines while keeping replacement charges for lost items, because fines raise little money, cost much of what they raise to collect, and lock out the young readers the library most needs to keep, and because a replacement charge preserves the responsibility that fines were meant to teach." The thesis names scope (overdue fines, not lost-item charges), significance (young readers are being locked out), and the value it answers (responsibility).

Distinguishing the claim and sequencing the argument. An opposing claim keeps fines. An alternate claim changes them without ending them: forgive fines for readers under 18 only, or cap them at 5 dollars. The introduction should say exactly where the writer's claim parts from both. A logical sequence for this audience is: significance and thesis; reason one (revenue and cost); reason two (blocked cards and who holds them); the strongest counterclaim (responsibility and returns) with its best evidence; the response; the alternate claim and why it falls short; conclusion. The counterclaim comes after the reader has seen the numbers so the response can use them.

Developing both sides fairly, with the most relevant evidence. For each body of evidence ask what it shows well and what it cannot show. The revenue figure is strong because it is audited income: 48,000 dollars is 0.6 percent of the budget. The collection cost is weaker because it is an estimate; if the estimate overstates the true cost, the net gain from fines is larger than 27,000 dollars, and if it understates the cost, smaller. And even an accurate estimate values staff time; it becomes a cash saving only if some expense actually falls, otherwise it is time freed for other work. The blocked-card figure is strong and significant: 4,440 young readers cannot borrow. The counterclaim's best evidence is the pilot's return rate, which fell from 91 to 89 percent. Its strength is that it comes from Castlemere's own branches; its limitation is that it covers two branches for one year with no comparison branches, so it shows a change but not what caused it, and a two-point drop is small in percentage points (whether it matters depends on how many items and how many days late). A fair writer states that the drop is real and that the pilot cannot show whether it would grow.

Varied syntax that links sections. Cohesion at this level comes from sentence structure as well as transitions. A concessive opening ("Granting that returns fell two points, ..."), an appositive that carries a limitation ("the collection cost, an estimate rather than a measurement, ..."), and a short sentence after long ones ("That is the trade.") each clarify the relationship between claim and reasons, reasons and evidence, or claim and counterclaim.

Formal style, objective tone and disciplinary norms. Policy writing names each source and its method; it uses exact nouns (cardholders, reactivated, replacement charges) and avoids intensifiers. An objective tone treats the people who value fines as holding a real principle.

A conclusion that follows from and supports the argument. It restates the claim with its conditions and states what the board should watch, without adding a new proposal.

Original model argument — first draft (kept for revision).

Library fines are an outdated punishment that hurts poor kids, and everyone who defends them just likes being strict. Fines barely make any money. The pilot proved going fine-free works because hundreds of people came back. Castlemere should end fines immediately, and also stop charging for lost books.

What is wrong with it. "Everyone who defends them just likes being strict" attacks the audience's motives and ignores the value of responsibility, which will harden the very readers the writer needs. "Proved" overstates one pilot, and the draft hides the fall in on-time returns. "Hundreds of people came back" turns 310 reactivated cards into returning readers; a reactivated card shows restored access, not a visit. "Poor kids" is not supported: the sources show age, not income. The conclusion adds a proposal on lost books that nothing argued.

Original model argument — revised draft (excerpt).

Castlemere Regional Library should end overdue fines while keeping replacement charges for lost items. The question matters because about 12 percent of the system's cards are blocked, and 60 percent of those belong to readers under 18, the patrons a public library can least afford to lose. Fines were meant to teach responsibility for shared property. A replacement charge keeps a cost attached to a lost item; a 10-dollar debt that bars a fifteen-year-old from borrowing may teach her only to stop coming.

Last year fines brought in 48,000 dollars, 0.6 percent of the budget. The finance office estimates that collecting them cost about 21,000 dollars. That figure is an estimate rather than a time study, and it values staff time that would be freed for other work rather than cash the library would save. Counting that time, the net loss from ending fines is about 27,000 dollars, more if the estimate overstates the cost; the gross loss is 48,000. Either way the amount is small beside the budget.

The strongest objection deserves its own evidence. During the fine-free pilot, on-time returns fell from 91 to 89 percent. Board members who value responsibility will read that as the cost of leniency, and they are right that it is a cost. It is also a drop of two percentage points whose practical weight the pilot does not report (how many items came back late, and how late), measured at two branches over one year with no comparison branches, so the pilot shows a change without proving that ending fines caused it. And it came alongside a gain: 310 of the pilot branches' 820 blocked cards were reactivated, which restores the chance to borrow even if it does not prove the holders came back.

Reading the revision. The thesis holds two considerations in tension. Significance is established early. The value of responsibility is answered directly rather than mocked, and the writer states the counterclaim's evidence with its real strength before limiting it.

Worked audience analysis: Audience: the Castlemere board. Knowledge: they know the budget, not how the collection-cost estimate was built, so the essay explains the method in one clause. Concerns: lost revenue and unreturned items, so revenue appears early and the return rate is stated, not hidden. Values: responsibility and access; the thesis keeps replacement charges to honor the first and cites blocked young readers to honor the second. Possible bias: status-quo bias, because fines are the existing system. The writer addresses it by framing both options as choices with costs: "Keeping fines is also a decision, and its cost is 7,400 blocked cards."

Worked strengths and limitations of both sides: Claim evidence, revenue: strength, audited income of 48,000 dollars; 48,000 divided by 8,000,000 is 0.006, or 0.6 percent. Limitation: small is not zero, and the collection-cost estimate that makes it smaller is not measured. Counterclaim evidence, pilot returns: strength, local data from Castlemere's own branches; limitation, two branches, one year, and a drop of 2 percentage points (91 minus 89). Stating both lets the reader trust the writer's weighing.

Worked arithmetic check: Blocked share: 7,400 divided by 62,000 is 0.119, about 12 percent. Young share of blocked cards: 4,440 divided by 7,400 is exactly 0.60. Reactivation: 310 divided by 820 is 0.378, about 38 percent. Net fine income under the estimate: 48,000 minus 21,000 is 27,000 dollars, where the 21,000 is the estimated value of staff time, not a cash expense that would disappear. Every percentage in the revised draft matches these calculations.

Worked syntax for cohesion: Two sentences: "Returns fell two points. The pilot was small." Revised with a concessive clause and an appositive: "Although on-time returns fell two points, the pilot, a trial at only two branches for one year, cannot show whether the drop would grow." The subordinate clause concedes the counterclaim; the appositive (a noun phrase renaming the pilot) carries the limitation; the main clause states the relationship between the evidence and the claim.

Planning record: Choose a position: end fines, keep them, or an alternate (fine-free for readers under 18, or a cap). Write a thesis that holds at least two considerations in tension and states the claim's significance. Build an audience grid with four rows (knowledge, concerns, values, possible biases) and, for each, one sentence the essay will use to address it. Then build a two-sided evidence table: source, what it shows well, what it cannot show. A partner reads your values row and writes whether a board member who disagrees with you would feel fairly treated.

Independent performance: Write a 700-900-word argument addressed to the Castlemere board. Success criteria: a clear and thorough thesis for a complex argument; precise, knowledgeable claims whose significance is established; the claim distinguished from one opposing and one alternate claim; a logical sequence of claims, counterclaims, reasons and evidence; the counterclaim developed with its most relevant evidence; strengths and limitations stated for both sides; at least one value and one possible bias of the audience anticipated respectfully; varied syntax, including at least one concessive clause and one appositive, that links major sections; every number traced to a named simulated source and calculated correctly; formal style and objective tone; a conclusion that follows from the argument. Submit the grid, the draft, the revision and a 100-word note on your most important change.
