Worms, cannibalism, and mazes(Potentially relevant link)
Before the cold fusion debacle, what did we use as the quintessential example of bad science?
One noder claims it was Dr. James McConell's experiments at the University of Michigan. Specifically, Dr. James McConell would have planarian worms run a maze. Once they were trained he chopped them up and fed them to some other planarian worms. These cannibal worms were then able to run the maze better than non-cannibal worms, or so McConell claimed. These results, however, were never reproduced.
What a surprise.
