The Jurassic Park film really dropped the ball regarding the core problem being raised by the book:
The biggest threat isn't the problem you're focusing on. It's the thing you never considered a possibility in the first place.
In the movie, you find out the dinosaurs are breeding on their own for a single scene and then it never becomes a plot point again. The only raptors they have to deal with are the three that escaped from the paddock when the electricity went out.
In the book, there are supposed to be 8 raptors. The system is designed to throw an alert if there are ever fewer than expected.
Nobody thought to add an alarm or interface for if there were more than expected, and by the time they figure it out there are over three dozen of the damn things running loose.
Think about how this can apply elsewhere. Not just industrial applications, but philosophically, economically, politically, or socially:
What looming catastrophe are you ignoring because you are so focused on its opposite?
What dangers and evils are you allowing to grow unchecked because you never considered them as a possibility?
Then Jesus said unto the sick, “you better have insurance.”
Then Jesus said unto the stranger, “are you here legally?”
Then Jesus said unto the hungry, “my taxes better not be paying for these loaves and fishes.”
Then Jesus said unto the poor, “this is your own fault.”
