There is a widespread belief that people can predict impending earthquakes from unusual animal behavior. Skeptics claim that this belief is based on selective coincidence: people whose dogs behaved oddly just before an earthquake will be especially likely to remember that fact. At any given time, the skeptics say, some of the world' s dogs will be behaving oddly.
Clarification of whether the animal behavior supposedly predictive of earthquakes is specific to impending earthquakes or can be any kind of unusual behavior would be most important to an evaluation of the skeptics' position.
