Why Courts Ignore Mathematical Odds

In legal trials, evidence that increases the mathematical probability of guilt often fails to increase the likelihood of a conviction. Our brains do not process trial evidence like a calculator, making justice surprisingly irrational.

This phenomenon reveals a deep disconnect between cold logic and human judgment. Instead of weighing probabilities as a computer would, jurors often rely on narrative consistency or emotional intuition when deciding a case. This means the strength of statistical evidence is frequently overshadowed by how well a story fits together. Consequently, a defendant might appear statistically guilty while still being perceived as innocent by a jury.
