Resonance vs relevance
What is Resonance vs relevance?
Relevance measures whether a result matches the query; resonance measures whether it matches the person's taste, which is the difference between a technically correct result and one that feels right.
Relevance asks whether a result matches the query. Resonance asks whether it matches the person. A search or recommendation can be perfectly relevant and still fall flat, because it answers the request without fitting the taste of the person making it.
Optimizing for resonance rather than relevance is the shift Galya is built around. It is the difference between a result that is technically correct and one a person actually wants, and it is where taste, not just keywords, does the work.
