Selfless heroism is not the best strategy during life-and-death situations such as accidents of natural disasters, as trying to save others first may lead to more deaths, a study warns. When strong members try to help weak members before they are secure themselves, both are dragged down and the group as a whole suffers, researchers said. The team found that in most life-and-death scenarios when variables such as the ratio of adults to seniors were adjusted, the rope strategy resulted in the highest overall survival rate. Researchers found that crucial to the success of the rope strategy, however, was the availability of simple tools for use by rescuers.
