Can Animals Plan for the Future?

Instinct vs. insight in animals' future-directed capabilities.

Key points

  • Some animals like dolphins can plan to some extent, but their enduring errors, even after many trials, suggest their foresight is restricted.
  • Animals appearing to "plan ahead" may be doing so because of instinct, rather than insight.
  • Squirrels, for instance, store nuts for the winter even if they have never experienced the approaching dark or cold.

At Disney World in Florida, scientists gave two bottlenose dolphins, Bob and Toby, a series of puzzles to put their planning abilities to the test. In one task, the dolphins were first shown how to pick up weighted rings with their beak and were then taught how to drop four of these weights into a container to release a tasty fish reward. Once Bob and Toby had learned this, the experimenters changed the difficulty level: now weights were spread out within 20 feet of the prize box, meaning the cetaceans had to do some fin work.

Yet rather than simply gathering up the four required weights in one trip, they did it by swimming back and forth between each object and the container. After several dozen trials, the experimenters moved the weights farther away still from the prize box, within a radius of nearly 150 feet.

Now this was too much hard work: Gradually, Bob and Toby started putting multiple weights on their beak at a time to shorten the journey. They did not always pick up the required four, however. Often the dolphins gathered up two, three, and even five weights, so they may have struggled a bit with the counting. Nonetheless, by carrying more than one weight at a time they demonstrated at least some capacity to think ahead.

In another task, the dolphins had to put a single weight into a box, but this time they also had to poke a stick inside to obtain the reward. There was a twist. The second step was only possible for about fifteen seconds after the weight had been dropped, before a sliding door sprang shut and prevented further access. This did not pose a big problem for the dolphins; they quickly learned to complete the sequence in time.

Next, however, the researchers placed the stick over 80 feet away from the box. Bob and Toby once again dropped the weight into the apparatus and then quickly swam to retrieve the stick. But when the door kept shutting before they had returned, they simply gave up. With a little more foresight, a simple solution would have presented itself: Go and get the stick first, glide back at a leisurely pace, and only then, with the stick at the ready, put the weight into the box. The dolphins did not appear to get it. They did not prepare.

Dolphins can evidently plan to some extent, but their enduring errors, even after many trials and opportunities to learn, suggest their foresight is quite restricted. As we will see, such results are typical for studies of animal planning. On the one hand, there is evidence of some competencies. Animals are not just mindless automatons. On the other hand, performance tends to be inconsistent, and tasks that might seem trivial to a human mind, even to a young child, often go unsolved.

Conflicting Ideas About Animal Minds

Humans hold rather conflicting ideas about the minds of other animals. Some people are attracted to what we call rich interpretations of animal behavior and readily attribute complex cognitive capacities to animals, while others are reluctant to do so and instead gravitate to lean interpretations.

Many people even vacillate between these views depending on the context (and what’s on the menu that evening). On the one hand, people frequently anthropomorphize, projecting all kinds of mental processes onto their pets—feelings, memories, expectations. On the other hand, those same people may treat other animals, especially those farmed for food, as if they had no mind at all.

Scientists, not immune to holding preconceived ideas, should guard against any biases influencing their research. Sensational rich claims about animals apparently thinking ahead in clever ways can be exciting, but they cannot be simply accepted at face value. These claims need to be tested in rigorously designed studies, and results need to be independently replicated. Before jumping to any conclusions about animal planning capacities, we must systematically rule out lean alternative explanations.

Future-Directed Instincts

Most species, great and small, face recurring patterns in nature such as fluctuations of light, temperature, and food availability that occur in periodic cycles. Even the humble bacterium E. Coli, infamously responsible for food poisoning, prepares. As it travels through lactose-rich human digestive tracts, it switches on genes for maltose digestion a couple of hours before it will reach the maltose-rich areas.

This preparation does not mean that the bacterium is fantasizing about maltose, however. The strains of E. Coli that happened to activate genes in this order survived and replicated more than the ones that did not, or the ones who did so too early or too late. If the long-term pattern stays the same, like how maltose always comes after lactose in the digestive tract of a host mammal, natural selection can forge behaviors that seem intelligently calibrated to upcoming events. The key takeaway here is that only genetic variability and a reliable sequence of environmental circumstances is required for such forms of preparation to evolve.

Creatures that act in tune with long-term regularities such as daily or seasonal variations can have a significant advantage over those that do not. There is perhaps no more conspicuous a case of preparation than that of squirrels and other animals storing food for barren winter months ahead. One would be forgiven for assuming that the squirrels must be imagining themselves hungry and without food in the midst of the coming frost.

But this is not why they hoard food. Even a young squirrel that has never experienced a winter will collect and store provisions. This simple fact tells us that the behavior is driven by instinct rather than insight. In other words, the squirrels have evolved a behavioral solution to the recurring challenge of wintertime food shortages. In a sense this adaptation may not be that different from whales storing fat in their blubber for migration without food, or Australian trees storing energy in swollen lignotubers at the base of their trunk that they can draw on after a fire.

So animals may end up preparing for nightfall or winter even if they do not think about the approaching darkness or cold.
