"Boiling frogs in warm water" refers to the "frog boiling experiment" conducted by American scientists at the end of 19. Scientists first put the frog into water at 40 degrees Celsius, and the frog jumped out of the boiling water because he couldn't stand the stimulation of high temperature. When the researchers first put the frog into a container filled with cold water and then heated it slowly, the frog was very comfortable in the water because of the comfortable water temperature at first. The frog found that he couldn't stand the high temperature, but he was unable to do so, and he was boiled to death by hot water before he knew it.
