TED-ED: Should you trust unanimous decisions? - Derek Abbott

The video explores the paradox of unanimity, where total agreement in decision-making can indicate errors or biases rather than certainty. It highlights the importance of considering uncertainty and variability, using examples like witness identifications and systematic errors in DNA evidence. The video concludes that while unanimity is ideal in low-uncertainty situations, it often signals hidden factors in complex scenarios.

In what ways can systemic errors arise in identification processes, according to the text?

What example is given to illustrate the dangers of relying on unanimous agreement in identification?
