You’ve heard of the boiling frog theory, right? Put a frog in boiling water and it’ll jump right out. But put it in cold water, then slowly bring that water to boil, and Mr. Frog will happily sit there until he’s cooked to death.
It’s completely wrong, of course. Put a frog anywhere and it’ll jump out – that’s just what frogs do – but, as a metaphor, the boiling frog theory’s pretty helpful. Because, as people, we act like boiling frogs all the time: unaware that the circumstances surrounding us are getting more urgent, but failing to do anything about it until it’s too late.
