Decision-Making Lessons: Humans often consider themselves highly rational decision-makers, yet making the right choice can be surprisingly difficult. We can become overwhelmed by too many options, influenced by emotions, trapped in disagreements or overly dependent on the opinions of others.

Interestingly, some of the most useful lessons about decision-making, teamwork, problem-solving and leadership can be found in creatures with brains vastly smaller than our own.

Insects such as ants, honeybees, locusts, cockroaches and fruit flies have developed sophisticated ways of responding to challenges. Their behaviour has attracted the attention of scientists because insect colonies can solve complex problems without having a central leader directing every individual.

Researchers have even drawn inspiration from insect behaviour to develop computer algorithms and systems for transportation, telecommunications, scheduling and logistics.

Although humans and insects are obviously very different, their behaviour highlights several principles that can improve the way we make decisions.

Decision-Making Lessons

1. Ants show the importance of exploring different options

One of the biggest challenges people face when making decisions is having too many choices. Whether deciding which career to pursue, selecting a business strategy or choosing between several solutions to a problem, an abundance of options can sometimes make decision-making more difficult. This phenomenon is often described as choice overload.

Ant colonies offer an interesting solution.

When ants search for food, they do not all follow a single predetermined route. Instead, different ants explore different paths. As they travel, they leave behind chemical signals called pheromones.

When an ant discovers a successful route to food, it returns to the colony and leaves a pheromone trail. Other ants are attracted to the trail and begin following it. Shorter and more efficient routes become increasingly reinforced because ants using those routes return more quickly and leave stronger pheromone trails. Less efficient routes gradually lose their chemical signals.

Eventually, the colony can identify an efficient route without any single ant possessing an overall understanding of the problem.

What humans can learn from ants

The lesson is that exploring multiple possibilities before committing to a decision can produce better outcomes.

In a workplace, for example, a manager does not necessarily need to identify the solution personally. Different members of a team can investigate different approaches, test them and report their findings. The group can then select the option supported by the strongest evidence.

This principle has inspired ant colony optimisation, a computational approach used to solve complex problems involving routing, scheduling, telecommunications and logistics.

Human takeaway: Don’t rush towards the first available solution. Allow different possibilities to be explored before choosing the most effective one.

2. Honeybees demonstrate the power of collective intelligence

Honeybees provide one of nature’s most impressive examples of collective decision-making.

When a colony needs to find a new nesting site, scout bees search the surrounding environment for potential locations. Once they return, they communicate information about their preferred sites through a distinctive behaviour known as the waggle dance.

The dance conveys information about the location and quality of a potential nesting site. More attractive locations receive stronger support from the scouts. Other bees can then investigate the proposed sites themselves rather than simply accepting another bee’s recommendation.

Eventually, enough bees support one location for the colony to reach what scientists describe as a quorum. The colony then commits to the decision.

This is remarkable because there is no single “boss bee” making the decision for everyone.

What humans can learn from honeybees

The lesson is that good group decisions can emerge when individuals gather information independently and communicate their findings effectively.

Consider a hospital management team deciding whether to introduce a new service. Instead of allowing one person to make the decision based solely on personal opinion, different members could examine the financial implications, staffing requirements, patient needs and potential risks.

Once everyone has contributed evidence, the organisation can make a more informed decision.

The same principle applies to families, businesses, governments, schools and community organisations.

Why disagreement can be useful

Honeybees also demonstrate that consensus does not have to mean immediate agreement. Individuals can initially support different alternatives, investigate them and gradually move towards a collective choice.

For humans, this means that disagreement is not necessarily a sign that a team is failing. Constructive disagreement can expose weaknesses in an idea and encourage people to consider alternatives they might otherwise overlook.

Human takeaway: Give people the opportunity to investigate, communicate and evaluate different options before reaching a collective decision.

3. Locusts show why sometimes it is better not to choose immediately

People often assume that successful decision-making means choosing quickly and confidently.

But research into locust behaviour suggests that temporary neutrality can sometimes help a group overcome disagreement.

When marching locusts are moving in different directions, they can become divided. Researchers found that when individuals temporarily stop and become neutral rather than immediately committing to one direction, the group can become more capable of changing direction and eventually reaching a new consensus.

Researchers also explored a similar principle with human participants. When people were given the option to choose between two alternatives or remain neutral, having that neutral option helped groups reach consensus more efficiently.

What humans can learn from locusts

Sometimes, the best response to a difficult disagreement is not to choose a side immediately.

Imagine two departments in an organisation disagreeing over how money should be spent. If everyone is forced to immediately support one side, the disagreement may become more intense. Allowing people to pause, review the evidence and remain undecided temporarily could create space for a better solution.

The same applies to personal decisions.

If you are uncertain about accepting a new job, investing money or entering into a major commitment, there is nothing inherently wrong with saying:

“I need more information before I decide.”

That is not necessarily weakness or indecision. It can be a deliberate decision-making strategy.

The power of pausing

A pause can help people:

• reconsider their assumptions;
• gather additional information;
• reduce emotional reactions;
• listen to opposing viewpoints;
• identify alternatives;
• avoid making an impulsive decision.

Human takeaway: When a decision becomes polarised, stepping back temporarily can sometimes help you see the situation more clearly.

4. Cockroaches reveal why diverse teams can make better decisions

Cockroaches are probably not the first animals people associate with effective leadership or teamwork. Yet research into their behaviour provides an interesting lesson about diversity within groups.

Individual cockroaches can have different behavioural tendencies. Some are more adventurous and willing to explore, while others are more cautious.

Computer simulations examining these differences found that groups containing a mixture of personalities could reach collective decisions more quickly than groups in which all individuals behaved in the same way.

However, too much of one behavioural tendency can create problems.

A group dominated by highly adventurous individuals may have difficulty settling on an appropriate shelter. On the other hand, a group made up mainly of cautious individuals may make decisions quickly but potentially select less suitable options.

What humans can learn from cockroaches

This has an important implication for workplaces and organisations:

A team does not necessarily become stronger simply because everyone thinks alike.

A successful team may need different kinds of people.

For example, consider a business team developing a new product. One person may constantly generate ambitious ideas. Another may focus on financial risks. A third may concentrate on customers. Someone else may challenge assumptions and identify potential problems.

At first, these differences may create disagreements. However, the combination can produce a more balanced decision.

Diversity of thought matters

A team where everyone agrees too quickly may fail to identify important risks.

Conversely, a team where everyone constantly challenges everything may struggle to make decisions.

The goal is therefore not simply to have different personalities but to combine different strengths in a productive way.

Human takeaway: Don’t build teams entirely around people who think like you. Different perspectives can improve problem-solving and decision-making.

5. Fruit flies show that emotions and experience can influence our decisions

Fruit flies may appear to have very little in common with humans when it comes to decision-making. However, research suggests that their choices can be influenced by both information from their environment and their internal state.

When faced with similar options, fruit flies may take longer to make a decision, suggesting that they are evaluating available information rather than responding automatically.

Their behaviour can also change depending on factors such as hunger and stress. These internal conditions can influence how they respond to different situations.

What humans can learn from fruit flies

Humans are also affected by their physical and emotional state.

Someone who is exhausted, hungry, angry or extremely stressed may make a different decision from the one they would make after getting enough rest and considering the situation calmly.

This does not mean emotions are always harmful. Our experiences and intuition can provide valuable information. However, recognising when our emotional state may be influencing our judgement can help us make more deliberate decisions.

For example, before making an important financial or professional decision, it may be useful to ask:

• Am I making this decision because I am angry?
• Am I under unnecessary pressure?
• Have I considered the evidence objectively?
• Am I tired or emotionally overwhelmed?
• Would I make the same decision tomorrow?

Human takeaway: Before making major decisions, understand the state of mind from which you are making them.

What these five insects teach us about leadership

Decision-Making Lessons: The lessons from insects go beyond personal decision-making. They also have important implications for leadership and management.

A traditional leadership model often assumes that the person at the top should have the answers and direct everyone else.

But insect colonies demonstrate another possibility: distributed intelligence.

Ant colonies do not need one ant to understand the entire food-search problem. Honeybee colonies do not need one bee to personally inspect every possible nesting location. Different individuals gather information, communicate it and collectively contribute to the final decision.

For human organisations, this suggests that leaders can sometimes improve outcomes by becoming facilitators rather than controllers.

A good leader can:

1. Encourage different people to explore solutions.
2. Create channels for information sharing.
3. Allow constructive disagreement.
4. Prevent one individual’s opinion from dominating.
5. Give teams enough time to evaluate evidence.
6. Recognise the value of different personalities.
7. Create an environment where people can change their minds without embarrassment.

Why collective intelligence can be more powerful than individual intelligence

One of the most important lessons from insects is that complex outcomes do not always require a highly intelligent individual.

Instead, relatively simple actions by many individuals can produce sophisticated results when those actions interact effectively.

This is sometimes called collective intelligence.

In human society, collective intelligence can be seen in:

• scientific research teams;
• emergency response organisations;
• healthcare teams;
• business organisations;
• community groups;
• software development teams;
• transport systems;
• online communities.

The quality of the final decision depends not only on how intelligent the individuals are but also on how effectively information moves between them.

A brilliant team can still make poor decisions if members are afraid to speak, if information is hidden or if one person’s opinion automatically overrides everyone else’s.

Five practical rules for making better decisions

Decision-Making Lessons: The lessons from ants, bees, locusts, cockroaches and fruit flies can be converted into practical rules for everyday life.

1. Don’t settle for the first solution

Explore several alternatives before committing yourself. The first idea may be convenient, but it is not necessarily the best.

2. Ask for different perspectives

When making an important decision, speak to people who approach problems differently from you.

3. Give yourself permission to pause

If you are uncertain, you do not always need to make an immediate decision. Sometimes additional information or time can reveal a better option.

4. Build diverse teams

Different experiences, personalities and ways of thinking can strengthen decision-making.

5. Check your emotional state

Before making a major decision, ask whether stress, anger, fear, exhaustion or excitement may be affecting your judgement.

The surprising wisdom of insects

Decision-Making Lessons: The behaviour of insects may seem simple when compared with the complexity of the human brain. Yet their survival depends on solving difficult problems involving food, shelter, threats, communication and cooperation.

Ants find efficient routes. Honeybees evaluate potential homes. Locusts adjust their collective direction. Cockroaches benefit from behavioural diversity. Fruit flies respond to both environmental information and their internal state.

Together, these examples demonstrate that effective decision-making is not always about speed, authority or individual intelligence.

Sometimes, the best decisions emerge from exploration, communication, diversity, patience and self-awareness.

Decision-Making Lessons: The next time you face a difficult decision, therefore, it may be worth remembering one of nature’s smallest lessons: you do not always need to be the smartest person in the room to make a smart decision. You simply need to know how to gather information, listen to others, recognise your own biases and choose the right moment to act.
