Gut checks are frequent, quick, focused tests of your ideas. Invite someone to give you a quick, gut-level reaction to a work-in-progress. You want an emotional or intuitive reaction that helps you clarify any bias you have as the creator. Go ahead and tell them you're just doing a gut check. The shorter their response, the better. It's not a brainstorm, it’s a fast tool to check your assumptions.
Ask a question so the feedback is focused. Use simple, direct questions and insist on simple, direct answers.
• What’s the first thing you notice?
• What is the most important thing on the screen?
• What’s the first emotion that comes to mind when you see this?
• Would you trust this?
• Is this funny?
