Making important decisions can be tough. Even after weighing all the options and doing thorough research, there’s always a lingering doubt about whether you’ve made the right choice. To ease this uncertainty, many people seek advice from friends or even strangers online, believing that a collective perspective is more insightful than a single viewpoint. This approach mirrors the concept of a hive mind, where a group of individuals shares knowledge to make smarter decisions collectively, often surpassing what one person could achieve alone.
While hive minds are often portrayed in science fiction, they exist in nature, with bees being a prime example. Bees use intricate communication methods within their hives to share crucial information and make collective decisions. Their communication is fascinating; they use dance to convey the direction, distance, and quality of food sources, potential new hive sites, and even nearby dangers. Remarkably, bees can also engage in democratic debates.
Scientists have discovered that a bee colony functions much like a single organism, similar to a human brain. By studying how bees interact, we can gain insights into our own decision-making processes. Although only about 10% of bee species are social, honeybees are highly social creatures. The western honeybee, Apis mellifera, is the most common species, forming large colonies with a single queen, numerous non-reproductive female workers, and a few fertile males. These colonies can house tens of thousands of bees, all organized through complex communication.
In the early 20th century, scientists believed bees communicated food sources through scent. However, in 1944, Carl von Frisch, a professor at the University of Munich, made a groundbreaking discovery. He observed that scout bees returning to the hive did not lead others to search for flowers with matching scents everywhere, but rather directed them to the precise location of the food source. This indicated that bees were communicating exact locations.
Von Frisch discovered that bees perform a “waggle dance,” a miniature reenactment of their recent flight, to indicate the location of food sources. The dance communicates the direction and distance to nectar and pollen. The duration of the waggle run indicates the distance, while the angle of the run relative to a vertical line tells other bees the angle of the journey in relation to the sun.
Bees also use their communication methods to discuss future hive options and make decisions democratically, a rare behavior in the animal kingdom. In late spring or early summer, honeybee colonies often become overcrowded, prompting them to find a new home. A third of the worker bees stay behind to rear a new queen, while two-thirds, along with the original queen, search for a new nest site. Scouts look for suitable locations, such as hollowed-out trees or abandoned structures.
When a bee finds a promising site, it returns to the group and performs the waggle dance to indicate the potential nest site. Other bees then investigate the site themselves. If they agree, they return and perform the same dance. Determining the best site can lead to vigorous debates among the bees.
In 1951, a study on bee debates showed how these discussions unfold. Initially, two scout bees reported different nest site candidates. Over the next few days, interest in various sites fluctuated, but ultimately, one site gained unanimous support. This process involves information gathering and a progression toward consensus, showcasing the hallmarks of a democratic process.
Recent studies have shown that bee decision-making resembles how neurons in the human brain function. This suggests that studying bee behavior could provide insights into human psychology. Psychophysical laws explain the relationship between real-world stimuli and perception. Many organisms, including bees, adhere to these laws when making decisions. For example, Weber’s law states that a change in stimulus must be a constant ratio of the original stimulus to be noticeable. Hick’s law indicates that decision-making slows as the number of options increases, while Pieron’s law states that decisions are quicker when options are of high quality.
In 2018, scientists found that bee colonies adhere to these psychophysical laws when making collective decisions. They were able to choose higher-quality nest sites when the difference exceeded a noticeable threshold. The colonies were slower to make decisions when faced with many alternatives but quicker when comparing two high-quality options.
The study of bee behavior has inspired computer scientists to develop algorithms based on bees’ decision-making methods. One popular model is the artificial bee colony (ABC) algorithm, used for optimizing problems by identifying the best solution among many options. In this model, each candidate solution represents a food source, and the quality of that solution is akin to the amount of nectar it holds.
The ABC algorithm has been applied to various real-world engineering problems, such as optimizing solar panel positions and planning re-entry trajectories for hypersonic vehicles. This intersection of biology and computer science opens up exciting possibilities for solving real-world challenges using nature-inspired solutions.
If you’re interested in learning more about algorithms and programming, consider exploring interactive challenges that make it easy to understand how algorithms work without getting bogged down in complex coding syntax. These resources can help demystify algorithms, making them feel like a fun puzzle.

[Music] Making big decisions can be challenging. Even after considering all the options, doing research, and selecting what you think is the best solution, there’s always a fear that you might have chosen incorrectly. To lessen that fear, many of us seek advice from friends or even strangers online, believing that multiple perspectives are better than just one. This kind of decision-making resembles a hive mind, where a large number of individuals share their knowledge, leading to collective intelligence. This often results in smarter decision-making among groups, surpassing what one individual could achieve alone.
While often depicted in science fiction, hive minds exist in real life, with many examples in nature. One notable example comes from bees, the insects that inspired the term “hive mind.” Bees use nest-based communication to share important information and collectively make robust decisions. Their methods of communication are quite fascinating; they communicate through dance, conveying the direction, distance, and quality of food sources, potential new hive sites, and even nearby dangers. Surprisingly, they can also engage in democratic debates.
This collective behavior is so powerful that scientists are beginning to understand that a bee colony functions much like a single organism, akin to a human brain. Studying how these remarkable creatures interact could provide insights into our own decision-making processes.
Although only about 10 percent of bee species are social, honeybees are highly social. Apis mellifera, or the western honeybee, is the most common of the honeybee species. They create large colonies with a single fertile queen, many non-reproductive female workers, and a small number of fertile males. Individual colonies can house tens of thousands of bees, and their activities are organized through complex communication.
In the early 1900s, scientists believed that bees communicated the presence of food sources through scent. However, in 1944, Carl von Frisch, a professor at the University of Munich, made a groundbreaking discovery. He observed that returning scout bees did not lead other bees to search for flowers with matching scents everywhere around the hive, but rather in the precise vicinity of where the foraging bee had been. This indicated that the exact location of the food source was being communicated.
Upon closer observation, von Frisch discovered that bees perform a waggle dance, which is a miniature reenactment of their recent flight, indicating the location of the food source they just visited. The dance communicates the direction and distance to nectar and pollen sources. The duration of the waggle run indicates how far the resource is, while the angle of the run relative to a vertical line tells other bees the angle of the outward journey in relation to the sun.
In addition to dancing, bees also share some of the nectar with their audience, which, combined with the lingering scent of the flower, helps recruits locate the food source. They communicate other messages through dance as well, such as a tremble dance that signals the need for more bees to process nectar into honey.
Not all bee conversations are about food sources; they also use these communication methods to discuss options for the future of the hive and make decisions democratically. This collective behavior is rare in the animal kingdom.
In late spring or early summer, honeybee colonies often become overcrowded in their nesting cavities, prompting them to find a new home. One-third of the worker bees stay behind to rear a new queen, while two-thirds, along with the original queen, begin searching for a new nest site. The quest starts with the swarm congregating at a temporary site, such as a branch or bush outside the old hive. From there, scouts look for suitable nesting locations, such as hollowed-out trees or abandoned structures.
When a bee finds a location it likes, it returns to the group and performs the waggle dance to indicate the potential nest site. Other bees then check it out for themselves. If they like it, they return and perform the same dance. However, determining the best potential nest site can lead to vigorous debates among the bees.
In 1951, one of the first studies on bee debates showed how these discussions unfold. On the first day, two scout bees were identified, one reporting a nest site candidate 1500 meters to the north and the other reporting a site 300 meters to the southeast. The following day, more dancers were identified, with some supporting each site and others reporting new sites. Over the next few days, interest in various sites fluctuated, but ultimately, one site, located 300 meters to the southeast, gained unanimous support.
Analyzing these debates reveals key features of the bees’ decision-making process. It begins with an information-gathering phase, followed by a progression toward consensus. The process is highly distributed, involving many individuals, showcasing the hallmarks of a democratic process. The dances performed by the bees indicate significant cognitive ability, as they must remember various locations and translate that information into their dance.
Recent studies have shown that the way bees work together resembles how individual neurons in the human brain function. This suggests that studying bee behavior could provide insights into our own minds.
Psychophysical laws explain the relationship between real-world stimuli and perception. Many organisms, including bees, adhere to these laws when making decisions. For instance, Weber’s law states that the change in a stimulus must be a constant ratio of the original stimulus for it to be noticeable. Hick’s law indicates that decision-making slows as the number of options increases, while Pieron’s law states that decisions are quicker when options are of high quality.
In 2018, scientists found that bee colonies adhere to these psychophysical laws when making collective decisions. They were able to choose higher-quality nest sites when the difference exceeded a noticeable threshold. The colonies were slower to make decisions when faced with many alternatives but quicker when comparing two high-quality options.
These findings support the idea that bee colonies function as superorganisms, similar to a complete organism. Just as a bee colony resembles a brain, individual bees act like neurons. Decisions are made when individual bees communicate their discoveries through visual displays, and if bees follow the same laws as neurons, observing them can enhance our understanding of human psychology.
In addition to insights into our minds, computer scientists have developed algorithms based on bees’ decision-making methods. One popular model is the artificial bee colony (ABC) algorithm, used for optimizing problems by identifying the best solution among many options. In this model, each candidate solution represents a food source, and the quality of that solution is akin to the amount of nectar it holds.
