To use impacts in summaries, you need to highlight and prioritize your impacts, and show why they are decisive for the judge's decision. You can do this by using impact calculus or impact framing. Impact calculus is when you compare and contrast your impacts with your opponent's, using the criteria of magnitude, probability, and timeframe. For example, you can say "our impacts are bigger, more likely, and more urgent than theirs, because we affect more people, have more evidence, and solve the problem now". Impact framing is when you explain why your impacts matter more than your opponent's, using values, principles, or perspectives. For example, you can say "our impacts are more important than theirs, because we uphold human dignity, justice, and peace, which are the core values of this debate".
