Theboiling frogis anapologuedescribing afrogbeing slowlyboiled alive.The premise is that if a frog is put suddenly into boiling water, it will jump out, but if the frog is put in tepid water which is then brought to a boil slowly, it will not perceive the danger and will be cooked to death. The story is often used as ametaphorfor the inability or unwillingness of people to react to or be aware of sinister threats that arise gradually rather than suddenly.

While some 19th-century experiments suggested that the underlying premise is true if the heating is sufficiently gradual,[2][3]according to modern biologists the premise is false: changing location is a naturalthermoregulationstrategy for frogs and otherectotherms,and is necessary for survival in the wild. A frog that is gradually heated will jump out. Furthermore, a frog placed into already boiling water will die immediately, not jump out.[4][5]

As metaphor[edit]

If you drop a frog in a pot of boiling water, it will of course frantically try to clamber out. But if you place it gently in a pot of tepid water and turn the heat on low, it will float there quite placidly. As the water gradually heats up, the frog will sink into a tranquil stupor, exactly like one of us in a hot bath, and before long, with a smile on its face, it will unresistingly allow itself to be boiled to death.

Version of the story fromDaniel Quinn'sThe Story of B

The boiling frog story is generally offered as ametaphorcautioning people to be aware of even gradual change lest they suffer eventual undesirable consequences. It may be invoked in support of aslippery slopeargument as a caution againstcreeping normality.It is also used in business to reinforce that change needs to be gradual to be accepted.[6]The term "boiling frog syndrome" is a metaphor used to describe the failure to act against a problematic situation which will increase in severity until reaching catastrophic proportions.[7]It thereby encapsulates the barely noticeable impact of slowenvironmental degradationthat has been described byDaniel Paulyasshifting baselines.[8]

The story has been retold many times and used to illustrate widely varying viewpoints: in 1960 about warning against those who wished fordetenteduring theCold War;[9]in 1980 about the impending collapse of civilization anticipated bysurvivalists;[10]in the 1990s about inaction in response toclimate changeand staying inabusive relationships.[11][12]It has also been used bylibertariansto warn about the slow erosion ofcivil liberties.[6]

In the 1996 novelThe Story of B,environmentalist authorDaniel Quinnspends a chapter on the metaphor of the boiling frog, using it to describe human history, population growth and food surplus.[13]Pierce Brosnan's character Harry Dalton mentioned it in the 1997 disaster movieDante's Peakin reference to the accumulating warning signs of the volcano's reawakening.[14]Al Goreused a version of the story in aNew York Timesop-ed,[15]in his presentations and the 2006 movieAn Inconvenient Truthto describe ignorance aboutglobal warming.In the movie version the frog is rescued before it is harmed.[16]This use of the story was referenced by writer/directorJon Cookseyin the title of his 2010 comedic documentaryHow to Boil a Frog.[17]

Law professor and legal commentatorEugene Volokhcommented in 2003 that regardless of the behavior of real frogs, the boiling frog story is useful as ametaphor,comparing it to the metaphor of anostrich with its head in the sand.[6]Economics Nobel laureate andNew York Timesop-edwriterPaul Krugmanused the story as a metaphor in a July 2009 column, while pointing out that real frogs behave differently.[18]JournalistJames Fallowshas been advocating since 2006 for people to stop retelling the story, describing it as a "stupid canard" and a "myth".[19][20]After Krugman's column appeared, however, he declared "peace on the boiled frog front" and said that using the story is acceptable if the writer points out that it is not literally true.[21]

In philosophy[edit]

Inphilosophy,the boiling frog story has been used as a way of explaining thesorites paradox.It describes a hypothetical heap of sand from which individual grains are removed one at a time, and asks if there is a specific point when it can no longer be defined as a heap.[22]

Experiments and analysis[edit]

During the 19th century, several experiments were performed to observe the reaction of frogs to slowly heated water. In 1869, while doing experiments searching for the location of the soul, German physiologistFriedrich Goltzdemonstrated that a frog that has had itsbrainremoved will remain in slowly heated water, but an intact frog attempted to escape the water when it reached 25 °C.[2][23]

Other 19th-century experiments were purported to show that frogs did not attempt to escape gradually heated water. An 1872 experiment by Heinzmann was said to show that a normal frog would not attempt to escape if the water was heated slowly enough,[24][25]which was corroborated in 1875 by Fratscher.[26]

In 1888,William Thompson Sedgwicksaid that the apparent contradiction between the results of these experiments was a consequence of different heating rates used in the experiments: "The truth appears to be that if the heating be sufficiently gradual, no reflex movements will be produced even in the normal frog; if it be more rapid, yet take place at such a rate as to be fairly called 'gradual', it will not secure the response of the normal frog under any circumstances".[3]Goltz had raised the temperature of the water from 17.5 °C to 56 °C in about ten minutes, or 3.8 °C per minute, in his experiment, whereas Heinzmann heated the frogs over the course of 90 minutes from about 21 °C to 37.5 °C, a rate of less than 0.2 °C per minute.[2]Edward Wheeler Scripturerecounted this conclusion inThe New Psychology(1897): "a live frog can actually be boiled without a movement if the water is heated slowly enough; in one experiment the temperature was raised at a rate of 0.002°C per second, and the frog was found dead at the end of 2½ hours without having moved."[27]

Modern scientific sources report that the alleged phenomenon is not real. In 1995,Douglas Melton,a biologist atHarvard University,said, "If you put a frog in boiling water, it won't jump out. It will die. If you put it in cold water, it will jump before it gets hot—they don't sit still for you." George R. Zug, curator of reptiles and amphibians at theNational Museum of Natural History,also rejected the suggestion, saying that "If a frog had a means of getting out, it certainly would get out."[4]In 2002, Victor H. Hutchison, a retired zoologist at theUniversity of Oklahomawith a research interest in thermal relations of amphibians, said that "The legend is entirely incorrect!" He described how acritical thermal maximumfor many frog species has been determined by contemporary research experiments: as the water is heated by about 2 °F (about 1 °C), per minute, the frog becomes increasingly active as it tries to escape, and eventually jumps out if it can.[5]
