关于温水煮青蛙的故事，事实上是，如果把青蛙扔进沸水里，青蛙立即就被涮熟了，如果青蛙放冷水里，即使加热速度慢至每分钟1.1度，青蛙依然会跳出热水里。
这个故事真正的寓意是，对任何来路不明的信息，需要认真思考甄别，并通过多方途径判断。信息进入大脑前要仔细过滤，避免让大脑变成微信朋友圈一样的信息垃圾筒

Modern sources tend to dispute that the phenomenon is real. In 1995, Professor Douglas Melton, of the Harvard University Biology department, 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." Dr. George R. Zug, curator of reptiles and amphibians at the National Museum of Natural History, also rejected the suggestion, saying that "If a frog had a means of getting out, it certainly would get out."[2]
In 2002 Dr. Victor H. Hutchison, Professor Emeritus of Zoology at the University of Oklahoma, with a research interest in thermal relations of amphibians, said that "The legend is entirely incorrect!". He described how the critical thermal maximum for many frog species has been determined by contemporary research experiments: as the water is heated by about 2 °F, or 1.1 °C, per minute, the frog becomes increasingly active as it tries to escape, and eventually jumps out if the container allows it.[3][21] |
