When you are searching for something, where would you rather spend the effort: researching or verifying returned results? Duane’s latest Substack explores the idea that AI search hasn't removed the effort needed, but has merely shifted where that effort is required. 🧵 1/5

AI Search Didn’t Remove Cognitive Load. It Moved It.
As AI takes over more retrieval and synthesis, consumers do less searching and more verification. That changes what information needs to survive between retrieval and belief.

What’s more important: prompt wording or prompt intent? “I don’t think users would search for that” is a common response to outputs of prompt generation or prompt selection. We don’t have a source of data (like AdWords Keyword Planner) to help us adjudicate/validate our prompt selection. 🧵 1/7
