  "summary": "Squiggle is a domain-specific probabilistic programming language optimized for intuition-driven estimation rather than data-driven inference, developed by QURI and adopted primarily in the EA community. GiveWell's quantification project using Squiggle found cost to double consumption of \\$169 (95% CI: \\$131-\\$1,185) compared to point estimates, demonstrating value of explicit uncertainty.",
