The most debated, most contested, and most revealing motions on OmeBate — and why they make for close, well-scored debates.
Artificial intelligence will do more harm than good
AI dominates every conversation about the near future. Both sides have strong material: displacement of jobs and concentration of power versus medical breakthroughs and productivity gains. The debate is close enough that it comes down to delivery.
Social media does more harm than good
Consistently one of the most-started topics on OmeBate. Debaters on the harm side cite teenage mental health data; defenders point to political organising, small business growth, and democratic access to information.
The death penalty can never be justified
A classic motion that never loses relevance. The irreversibility of execution and wrongful conviction risk anchor the Pro side; retributive justice and deterrence power the Con. Emotion runs high but the best debaters keep it evidence-based.
Climate change is the greatest threat facing humanity
The scope of the motion rewards big-picture argumentation. Challengers on the Con side typically argue pandemics, nuclear war, or AI misalignment as greater existential risks, which forces a nuanced comparative debate.
Universal basic income would do more good than harm
A policy debate with real pilot data from Finland, Kenya, and Alaska to draw on. Pro debaters argue automation readiness and poverty elimination; Con debaters counter with inflation risk, work disincentives, and implementation cost.
Free speech should have no limits
Philosophical and political at the same time. The absolutist position is easy to state and hard to defend; the limits position requires drawing lines that debaters immediately challenge. A revealing test of logic under pressure.
Voting should be mandatory
Deceptively simple. The democratic legitimacy case for compulsion is strong; the individual liberty and protest-vote arguments for opposition are equally principled. Outcomes on OmeBate are roughly 50/50 — ideal for close scoring.
Nuclear energy is essential for a green future
An increasingly live policy debate. Pro debaters have accident probability statistics, France's emissions record, and next-generation reactor design on their side. Con debaters focus on Fukushima, Chernobyl, waste storage, and build time.
Smartphones should be banned in schools
High-stakes for parents and educators and instantly relatable to most debaters. Research on attention, sleep, and social development fuels the Pro side; digital literacy and emergency access anchor the Con.
Billionaires should not exist
A motion that sounds simple but opens into deep territory fast — inherited wealth, taxation, voluntary philanthropy, and the relationship between economic incentive and innovation. One of the highest-scoring debates when both sides are prepared.
Drugs should be decriminalised
The harm reduction evidence from Portugal is the cornerstone of the Pro argument. Con debaters argue social fabric, gateway effects, and enforcement signals. Evidence quality determines the outcome here more than rhetoric.
Animals have the same moral worth as humans
A philosophical deep-cut that rewards debaters who know their Peter Singer from their Kant. The motion forces both sides to define moral worth — and whoever does it better usually wins.
