Progressive Query Explorer
Does showing an approximate answer now help people explore more effectively than making them wait for an exact answer?
An instrumented, browser-native research prototype for studying how response latency and progressive refinement affect exploratory analysis. Users cross-filter one million property transactions while switching between immediate sample-based feedback and conventional exact queries.
- Experimental variable
- Exact results versus progressive sample-to-exact refinement
- Research system
- Five linked views over partitioned Parquet, queried locally with DuckDB-WASM
- Observable evidence
- Timings, interactions, and exploration traces can be exported for analysis
A controlled study can compare time-to-first-action, breadth of exploration, abandonment, and confidence across exact and progressive conditions.
