Weigh Impacts
Impact weighing answers a simple question: if both sides are right about something, which consequence should matter more to the decision?
Start with a real comparison
Side A: the policy saves every household $5 per year.
Side B: the policy prevents a smaller number of people from losing access to an essential service.
Both impacts are real. Now the debate becomes: which matters more?
How serious is the effect?
A small inconvenience and a severe harm should not be treated as equal just because both affect people.
How many people are affected?
Scope matters, but numbers alone do not decide the debate.
A severe harm to a smaller group may outweigh a tiny benefit to a larger group.
How likely is it?
A huge impact that is very unlikely may matter less than a smaller effect that is almost certain.
How long does it last—and can it be fixed?
Temporary effects often deserve less weight than permanent ones.
Hard-to-reverse harms may deserve special attention.
Example
Imagine one policy saves millions of people a few dollars, while another prevents a much smaller number of people from losing access to emergency healthcare. You should compare severity, number affected, probability, duration, and reversibility—not just count how many people appear on each side.
Common mistake
Assuming the biggest number or most dramatic wording automatically wins the impact comparison.
Try this
Take two impacts from a debate and compare them using five questions: How serious? How many people? How likely? How long? Can it be reversed?
Keep in mind
Weighing is how you turn two valid arguments into one decision.
Practice this skill
Use it in a real debate and see how well it holds up when you have to respond to an opponent.
