Tsunami Survivor Warns: Your Mind Can Kill You

A father who lost his child in Japan's 2011 tsunami has a urgent message. He says certain human instincts can be fatal during a disaster. His 12-year-old daughter died when a giant wave hit Japan's northeast coast. The disaster killed thousands. Now, he works to teach people about dangerous thought patterns. One major trap is "normalcy bias." This is when people underestimate a threat because the situation feels ordinary. They might delay life-saving action. Another is "groupthink." People will follow a crowd, even if the crowd is moving into danger. They ignore their own doubts. The father stresses that recognizing these mental traps is vital. He believes understanding them will save lives in future crises. His goal is to turn personal grief into a universal lesson on survival.
