Boiling Frog

The most dangerous changes are often the slowest ones.


The Boiling Frog describes how gradual change slips past our alarms. Each small step feels normal compared to yesterday, so people and organisations stay put while conditions get steadily worse.

To use it, compare today against a fixed reference point, like last year, not last week. Set tripwires in advance that trigger action when crossed, and review your health, money and relationships regularly.
