Discuss an example of how failures of critical thinking often contribute to unfortunate accidents.

Failures of critical thinking often contribute to some of the saddest and most unfortunate accidents. At Yosemite Park's Vernal Falls, three young people stepped passed the guard rails to take pictures. Other park visitors called to them, urging them to get back to safety, but they did not. Then suddenly one fell, the other two tried to help, and all three were swept over the falls to their deaths. If they had thoughtfully considered the risks and benefits, we doubt that they would have made the tragic decision to ignore the posted warnings.
