How juries are fooled by statistics

Mistakes in interpreting statistics can have devastating real-world consequences, especially in legal trials. A single numerical error once helped convict a mother of murder after the tragic deaths of her two children, when flawed probability reasoning obscured the truth. People routinely misjudge probabilities, such as overestimating the accuracy of medical tests or misunderstanding the odds in random events. Recognizing and correcting these statistical blind spots is essential for justice and good decision-making.
