They Saw It. They Fixed It Wrong. On July 1, 1940, the Tacoma Narrows Bridge opened in Washington state. It was an engineering marvel: a suspension bridge spanning 2,800 feet with the longest center span in the world at that time. The design was revolutionary—the deck was thinner and more flexible than previous bridges, giving it a distinctive, almost delicate appearance. Traffic was modest at first but growing. ...

It Just Didn’t Speak. On the morning of January 28, 1986, the Space Shuttle Challenger lifted off from Kennedy Space Center with 7 crew members aboard. 73 seconds later, the vehicle disintegrated in the sky, killing everyone on board. The technical cause was well understood within minutes: an O-ring seal in the right solid rocket booster had failed in the cold temperatures, allowing hot gases to escape and erode the external tank. ...

The Failure Was Psychological. On April 10, 1912, the RMS Titanic departed Southampton carrying 2,224 passengers and crew. Within five days, the ship would sink in the North Atlantic, killing 1,503 people. The tragedy wasn’t caused by incompetent design. Quite the opposite. The Titanic was built by Harland and Wolff, the world’s premier shipbuilder, at a cost equivalent to $200 million today. Its watertight compartments, double bottom, and advanced steam engines represented the cutting edge of 1912 engineering. The ship’s designers were the best available. The technology was state-of-the-art. Yet these advantages became fatal liabilities because they triggered a psychological mechanism so powerful it rendered obvious risks invisible: the expert blind spot combined with systematic normalization of deviance. ...
