Do Monkeys Understand Money? The Time Scientists Tried to Teach Them Economics

Monkeys are known for their impressive cognitive abilities, problem-solving skills, and social behaviors. But could they grasp the abstract concept of money? In a fascinating experiment, scientists attempted to teach monkeys about economics, challenging their understanding of value and trade. The results were intriguing, revealing both the similarities and differences between human and primate thinking when it comes to financial concepts.

The Experiment: Teaching Monkeys Economics

The concept of teaching monkeys about money isn’t as strange as it sounds. In fact, psychologists and animal behaviorists have long been interested in understanding how non-human primates perceive and use symbolic representations of value, including currency. One of the most famous studies on this topic was conducted by researchers in the 1990s, where capuchin monkeys were taught to trade objects for food using “monetary” tokens.

The Setup: Tokens as Currency

In this study, the researchers gave capuchin monkeys a set of tokens that could be exchanged for food. The tokens weren’t real money, of course, but they served as a stand-in for currency. The monkeys could “buy” treats such as grapes or pieces of cucumber by exchanging these tokens. The goal was to see whether the monkeys would understand that the tokens had value and could be traded for something they desired.

The Learning Process

At first, the monkeys didn’t immediately understand the concept. They were confused by the tokens and did not immediately associate them with food. However, over time, the monkeys began to learn the connection between the tokens and the food. Some monkeys quickly figured out that collecting tokens allowed them to “purchase” treats. This process resembled the early stages of human economic learning, where we develop the concept of value and exchange.

Advanced Economic Concepts: Fairness and Bargaining

The experiment didn’t stop at simple exchanges. Scientists also introduced more complex economic principles, such as fairness and bargaining. In one part of the study, the researchers observed how monkeys responded to inequitable exchanges. For example, when one monkey was given a higher-value treat (like a grape) in exchange for a token, while the other received a lower-value treat (like a cucumber), the monkeys began to display signs of dissatisfaction and frustration. Some even refused the cucumber after seeing the other monkey get the grape, displaying a sense of fairness akin to humans’ desire for equal treatment in transactions.

What Did the Monkeys Understand?

While the monkeys didn’t fully grasp the abstract notion of money as humans do, they showed an understanding of several basic economic principles:

1. Value and Exchange

The most straightforward concept the monkeys understood was that tokens could be exchanged for food. This mirrors the basic function of money in human societies, where currency is exchanged for goods and services.

2. Fairness

The monkeys’ reactions to unequal exchanges suggested that they have a sense of fairness, at least in terms of equitable trades. This insight is intriguing because it implies that some rudimentary social and economic principles, such as fairness, might be rooted in primate behavior.

3. Delayed Gratification

Some monkeys demonstrated the ability to delay gratification, holding onto tokens in order to exchange them for a higher-value reward. This behavior resembles the concept of saving and investing in human economics, where people forgo immediate pleasure in exchange for a larger, delayed return.

4. Bargaining

The monkeys also showed the beginnings of bargaining behavior. When given a choice, some monkeys attempted to trade tokens for different types of treats, trying to maximize their benefit. This could be seen as a primitive form of negotiation or bartering.

What Did They Miss?

Despite their impressive cognitive skills, the monkeys did not fully comprehend some key aspects of human economics. For instance:

1. Abstract Money Concepts

The monkeys understood the practical use of tokens but did not grasp the concept of money as an abstract idea. In human societies, money can represent value in nearly any form—whether it’s physical currency, digital transactions, or future investments. Monkeys, on the other hand, were limited to using tokens within the confines of the experiment.

2. Financial Planning

While some monkeys demonstrated delayed gratification, they didn’t seem to engage in long-term financial planning or investment strategies. They would use tokens when they wanted something, but they didn’t save or accumulate tokens for future purposes, as humans might do with money.

3. Economic Systems

Monkeys did not develop a broader understanding of economic systems, such as supply and demand, inflation, or market fluctuations. The experiment was focused on individual exchanges, rather than understanding how an entire system of trade and value works.

What This Tells Us About Monkeys and Money

The experiment revealed that while monkeys can understand some basic principles of economics, they are far from grasping the full complexities of human financial systems. However, the fact that monkeys can engage in transactions and show a sense of fairness suggests that some elements of economic behavior are rooted in our evolutionary past.

Their ability to comprehend value, trade, and fairness points to the possibility that the foundations of economics—at least on a basic level—may be shared with our primate relatives. But, just like us, they have their limits. Monkeys may not be ready to trade stocks, invest in real estate, or debate the merits of cryptocurrencies just yet, but their ability to understand the basics of value exchange is a fascinating glimpse into the complex minds of our closest animal relatives.
