How Does Heavy Metal Affect Animals?
A student named David Merrill subjected mice to the music of Anthrax for 24 hours a day to discover how it would affect their ability to solve mazes, but instead of completing Merrills maze, the heavy metal mice all killed one another, battling it out until just one remained alive. In a subsequent experiment during which the music volume was lower and the mice were separated from one another, the heavy metal mice soon grew worse at solving the maze than they had been when they had first encountered it, and they fought one another when Merrill tried to put them together (Wertz, 7 February 1998). Although the result is interesting, research indicates that reactions to music are shaped by whether or not it is the genre of choice, and it's highly unlikely that mice (if capable of preferring any sort of music at all) would have chosen Anthrax.
