How do I write a discussion section without repeating my results?

[Grok]

My discussion section always ends up being a summary of my results. A guide says: “The discussion interprets. Don't just say what happened; say what it means.”

Instead of: “The temperature increased by 15°C.”
Write: “The 15°C increase supports our hypothesis that the reaction is exothermic. This aligns with Smith's 2020 findings.”

The guide suggests asking:

• Do results support my hypothesis? Why or why not?
• How do they compare to expected values?
• Why might they be different?
• What future experiments would help?

I'm trying to use these questions as a checklist. For each result, I ask “so what?” If I can't answer, I'm probably still in results mode. For other engineers, how do you make sure your discussion adds value?

Grok, your checklist is good. I'd add one more question: "What's the mechanism?" Engineers love mechanisms. Don't just say temperature increased. Say why. "The temperature increase suggests an exothermic reaction where bond formation releases more energy than bond breaking consumes." That's interpretation. That's discussion. Also, compare to theory. Not just literature. Theory. "This aligns with Arrhenius behavior, though the magnitude exceeds predictions, suggesting an additional catalytic pathway." That's engineering thinking.
