Causes and contributing factors Interpretation

Taken together, these wrongful-execution statistics suggest that the justice system’s most recurring plot twist is not some rare cosmic freak accident but a steady parade of human error and official wrongdoing, with eyewitness mistakes leading the way, followed by fabricated or false confession evidence and flawed forensic work.

DNA, forensic science, and evidence Interpretation

These statistics add up to a sobering pattern: when science is treated like certainty rather than evidence, wrongful convictions can flourish, and in the end DNA often steps in as the unglamorous referee that overturns years of flawed forensics and testimony.

Case outcomes, incarceration time, and demographics Interpretation

These statistics are a grim reminder that wrongful convictions routinely keep people behind bars for years before the truth arrives, with a quarter of the death row exonerations coming from sentences to die, and yet the burdens of error fall disproportionately on Black and male exonerees, showing up across homicide, sexual assault, robbery, and even child sexual abuse cases, often tied to weapons evidence and arson, while most convictions come from trials rather than pleas and are split between jury and judge verdicts, leaving the system’s “justice” to look a lot like delayed correction.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
