Compare Competing Evidence
When both sides have evidence, the debate does not end. It becomes a comparison of what each source proves and which effect matters more.
Compare relevance
Which source answers the exact question in dispute?
A study can be strong but about the wrong outcome.
Compare method and scope
Look at sample, design, recency, and whether the effect is consistent.
Do not compare source names; compare what they actually did.
Compare what the evidence means
Two sources can both be true and still support different impacts.
Explain which impact should drive the decision.
Example
One study shows a policy raises costs. Another shows it increases access. Both may be true. The debate is now whether the access gain is worth the added cost.
Common mistake
Responding to one statistic with another statistic and stopping there.
Try this
Place two sources side by side and finish: “Even if both are true, ours matters more because…”
Keep in mind
Evidence clashes are won through comparison, not volume.
Practice this skill
Use it in a real debate and see how well it holds up when you have to respond to an opponent.
