- Peron’s tree frogs repeatedly enter a wood-fired hot tub on the author’s property in New South Wales, where slow heating leads to some dying, despite available escape routes.
- Carl Fratscher conducted experiments in 1875 showing frogs remained in water gradually heated from 20°C to 38°C over 2 hours and 15 minutes, but tried to escape when temperature rose rapidly.
- Jodi Rowley at the Australian Museum states frogs are highly sensitive to gradual temperature changes and typically respond by moving, calling the boiling frog idea a myth.
- Marco Gallio and colleagues studied fruit flies and found their brains respond strongly to rapid temperature increases but not slow ones, suggesting a biological basis for delayed escape behavior.
- The author now routinely removes frogs from the hot tub before heating and during warm-up, acknowledging a recurring cycle of frogs returning nightly despite daily relocation.
Why it matters: The persistence of frog fatalities in a real-world slow-heating environment challenges the scientific dismissal of the boiling frog metaphor, suggesting that under certain conditions, some animals may fail to respond to gradual threats—mirroring human inaction on issues like climate change. This has implications for how we interpret behavioral responses to incremental risks.
