Some types of animals, particularly domesticated animals such as dogs, have performed well in the trial over the years, Zimmer added. About a decade ago, Byrne first came up with the idea of putting elephants through the experiment. He and Smet finally had the opportunity to do so last year while on location in Zimbabwe. Every morning when the elephants were waiting to take tourists for a ride, Smet set up two buckets behind a screen. One of the elephant’s handlers would then lead one of the animals to within a few yards of Smet. The elephant stood by and watched as she lowered pieces of fruit behind the screen and into one of the two buckets. However, the elephant could not see which bucket she put the fruit in.
