It's even more necessary in meatspace (LOL!) but we learn to be subtle about it. This analysis is very insightful. Proper listening is cognitively expensive. In many circumstances it can't happen in real-time. Ideas are big and words are small. Both echoic and working memory are very limited. We have no choice but to optimize. Hashing is very efficient. We can hold a lot in our long term memories. The problem is that your new idea isn't in my head already. We need "idea arithmetic" to utilize our existing ideas without voiding new ones. The concept chicken-burger can be represented as hamburger + chicken - beef. That happened to be a perfect match. If it were Bob's Best Turkey Burger then it would be hamburger + chicken - beef ± ???. This is a more optimal representation than just ???. Each "chunk" saves memory for the most novel and important details. Assuming we continue listening. If we run into a chunk we don't like we're liable to start preparing arguments instead. Sometimes we're just tired and decide the match was good enough. The problems with this algorithm occur when it terminates early.
