The Persuasive Essay That Overreaches
A student writes a persuasive response arguing that social media should be banned for under-16s. The thesis is clear. The body paragraphs, however, rely on: 'Everyone knows social media is toxic'; 'A study shows it causes depression'; 'If we don't act now, an entire generation will be lost'. The student cites no source for the study and uses 'clearly', 'obviously' and 'undeniably' eleven times across 600 words. The teacher's feedback says the argument is 'asserted rather than built'. The student protests that persuasive writing is supposed to be forceful. The task requires the student to revise the body paragraphs to meet the demands of persuasive writing for a sceptical adult audience.
1. Explain the difference between forcefulness and persuasion, using examples from the draft.

Forcefulness raises the volume of a claim; persuasion supplies the grounds that make a sceptical reader accept it. The draft confuses the two. 'Everyone knows social media is toxic' is an appeal to consensus that a sceptical reader can simply reject by denying the consensus. 'A study shows it causes depression' is more promising but unusable without a source, because an unsourced study is an assertion dressed as evidence. The slippery-slope claim that 'an entire generation will be lost' maximises emotional pressure but sacrifices credibility, since no reasonable reader accepts total loss as a likely outcome. Intensifiers such as 'clearly' and 'undeniably' do not strengthen an argument; they often signal that the writer expects resistance. Persuasion works through specific, checkable evidence, acknowledgement of counter-arguments, and calibrated claims. The student's instinct that persuasive writing should be forceful is not wrong, but force should come from the weight of evidence and the logic of the case, not from adverbs.
2. Revise one body paragraph to demonstrate evidence-based persuasion, and annotate three changes.

Model revision: 'Critics of a ban argue that teenagers need online spaces to build friendships, and that argument deserves a serious answer. The evidence on harm is strongest for sleep and body image rather than for friendship itself. A 2023 review of adolescent wellbeing found associations between heavy evening use and shortened sleep, though the authors noted that causality remains contested. A ban is therefore best defended narrowly: restricting late-night algorithmic feeds, rather than removing social contact, targets the harm the evidence actually supports.' Annotation one: the counter-argument is stated fairly before being answered, which builds credibility with a sceptical reader. Annotation two: the evidence claim is hedged ('associations', 'causality remains contested'), which is more persuasive than overclaiming because it survives scrutiny. Annotation three: the proposal is narrowed to match the evidence, so the conclusion follows from the premises rather than exceeding them. The paragraph is less loud than the original but far harder to dismiss.
