Would giraffes pick an event with 99% chances of success, or 1% of failure?
In later experiments, researchers divided the tubs in half and restricted themselves to picking vegetables in the top half. The ratio of carrots to zucchini differed in the top half compared to the entire tub and would require a combination of spatial reasoning and probabilistic evaluations.
Although three of the giraffe subjects were baffled at this prospect, the fourth subject figured the test out after just one round and kept picking carrots since then. These experiments were conducted after taking measures to ensure that the giraffes would not make their choice based on the smell of theSo what does this mean? Do giraffes love carrots just like rabbits? Um, maybe? That’s not the point here.
Giraffes, despite having small heads and a smaller brain within, performed just as well as chimpanzees in these tests.. Perhaps the giraffe lives a life involving complex herd dynamics and an assortment of food that inculcates this reasoning, even with little mental capacity to spare. Or perhaps probabilistic reasoning isn’t as rare as we think among animals.
Even though they can process probabilities and chances, it isn’t always on show when presented with a task that requires a combination of abilities.The ability to make inferences based on statistical information has so far been tested only in animals having large brains in relation to their body size, like primates and parrots. Here we tested if giraffes , despite having a smaller relative brain size, can rely on relative frequencies to predict sampling outcomes.
