This It's kind of like [[chunking]] to separate one long event like a lecture into shorter events, so each short context has a peak-end to be captured in memory. It's also like how in [[Flow]] we lose track of time in the moment, we also lose track of time in our memory and compress. This also reminds me of how [[We see the world in stories]], so we create a story about events, and [[we are all the hero of our own story]], so we put ourselves in the center of that story. We can ensure that we each have the story of the event that we want, by focusing on the key parts. Since [[You make great things by making something good and revising]], only the people who participate can tell you what needs to be improved to get to this effect. This is a psychological effect, shown by Kahneman and Taversky, to affect many of our memory recordings. It was shown in this case to be in place in colonscopy memory recording. If you prolonged the event, but the very end was less painful, then they had a memory of the event that was less painful. It matters because this can be used to ensure that people have a positive experience when they participate in activities, by focusing on the peak and the end. ### What would the opposite argument be? Using this is manipulation, focus on the whole event being right, and you will make the best event. ## Sources: [[Thinking Fast and Slow]]
