Affirmative · RebuttalRead the case: The four-day workweek
Resolution A four-day, 32-hour standard work week should replace the current five-day, 40-hour model
24 volunteer workplaces, covering offices, retail and distribution, joined a six-month comparison.
- Half were assigned by lottery to 32 hours at unchanged weekly pay; half kept 40 hours.
- Both groups maintained an output index of 100.
- Absence averaged three days per worker in the shorter-week group and five in the comparison group; these counts were not adjusted for scheduled days.
- Customer coverage was maintained, but payroll in the shorter-week retail and distribution sites was 8% higher; office payroll was unchanged.
- Healthcare and other continuous-service industries were not included.
For this practice round, the affirmative defends replacing the normal 40-hour model with a 32-hour standard at unchanged weekly pay; it does not claim every shift must be identical. The negative challenges whether the benefits justify the costs of that replacement.
When the other side attacks your reasoning, figure out exactly which step they are going after. You might have support to defend it, a narrower version worth keeping, or a stronger argument to move to.
Your defense has to answer the attack, not repeat your evidence. Explain why the link still holds in this situation and how much the attack actually changes.
Maintained output makes a shorter week feasible in the workplaces studied.
The affirmative claims the change can work. It never claimed it would be free.
But payroll rose in retail and distribution.
This attack lands only if the affirmative had claimed the change was free.
The work was completed with shorter hours, so the feasibility point stands. The additional payroll changes the cost-benefit comparison; it does not erase the time gain or turn maintained output into failure.
The reply defends the original point and names the cost as a separate question.
We argue the time gain is worth that cost. The negative should challenge that comparison, rather than treating a cost as proof that the schedule cannot work.
Now the next speech has a clear fight: is the benefit worth the cost?

Read the case: Meritocracy as practiced
Resolution Meritocracy as practiced in modern societies is a harmful fiction that should be rejected
a hiring audit compares 100 lower-income and 100 higher-income applicants.
- Their anonymous work-sample scores were similar, but CV review shortlisted 30 lower-income and 60 higher-income applicants.
- Among those hired, work-sample scores tracked six-month job performance more closely than CV rank.
- In a later cohort, free preparation and an anonymous first stage reduced the shortlist-rate gap from 30 to 10 percentage points; other changes were not controlled.
The affirmative argues that calling the existing process meritocratic legitimizes an advantage not explained by demonstrated ability. The negative argues that useful ability assessment and the improvement after reform are reasons to repair the practice rather than reject it. Neither side may treat this single practice audit as a description of all societies.

Your response
You can return to the practice whenever you want.
One model response
Useful work-sample assessment does not establish that the CV-based process already rewarded that ability. Our criticism concerns the current shortlist and the claim that its advantage reflects merit, despite similar task scores. We can preserve relevant assessment while rejecting a description that treats background advantage as deserved. The negative’s evidence becomes a debate about reform and replacement, not a refutation of a claim that all assessment is useless.
The useful measure is not automatically the measure used in selection.
The comparison in the evidence gives the criticism a factual basis.
The reply identifies where the remaining disagreement belongs.
The response defends the affirmative’s actual point: the problem is how assessment is used today, not assessment itself.
