Big data and scientific analysis are transforming how trial lawyers prepare and win cases. Tools like JuryBall enable attorneys to test and refine strategies using large-scale mock jury studies, predictive analytics, and iterative feedback loops. This approach helps litigators in both civil and criminal cases accurately forecast trial outcomes, improve arguments, and make smarter decisions—from case valuation to jury selection. By shifting from gut instinct to data-driven insight, trial lawyers can dramatically improve outcomes and redefine what it means to be prepared for trial.
