People judge an experience largely based on how they felt at its peak and at its end, rather than on the total sum or average of every moment of the experience.

Learning about the Peak-End Rule in Chapter 6 of Laws of UX was a particularly engaging experience for me. Unlike some of the more technical principles, this law felt immediately relatable and intuitive. The idea that users judge an experience largely based on its most intense point (the "peak") and its ending makes perfect sense when I think back to my own memorable interactions with apps, websites, and even real-world services.

What stood out to me most was how much influence designers have over users' lasting impressions. It’s not enough to simply make an experience functional; what users will remember is how they felt during the most emotional moments and at the end. This realisation feels important as I continue to build my understanding of effective UX design. I’ll definitely keep this principle in mind moving forward, especially when designing key moments like onboarding experiences, confirmation screens, or end-of-task celebrations.

Another valuable aspect of the chapter was the discussion of user journey maps. I’ve heard of journey mapping before, but the chapter helped me see how it ties into managing users' peak and end experiences. Mapping out the journey can reveal opportunities to deliberately design emotional highs and ensure satisfying conclusions. I found this particularly useful because it provides a structured way to think about user emotions throughout a flow, rather than just focusing on isolated screens.

Overall, the Peak-End Rule feels like a powerful, human-centred design tool. It reminds me that good UX is not just about efficiency or simplicity—it's about creating emotional resonance. I’m excited to apply this insight into my future projects, designing not only for usability but also for memorable, positive experiences.
