What are the "decision-making methods" that humans should learn from honeybee society?

Discussions that are slow and inconclusive are often described as "The meeting dances, but doesn't progress, But the bees are called "Figure eight danceThe conference held in "" hides a simple and efficient mechanism.

Overcoming Bias: How Bees Argue

Bees leave from late spring to early summer, with newly born queen bees traveling with worker beesBeeTo expand the power. At this time, the number of worker bees following the new queen will reach about 10,000, which is 2/3 of the worker bees in the original nest. The swarm of the new queen bees gather in one place, overcoming the rain and wind, and send out 300-500 experienced worker bees as scouts on all sides to search for new nest sites.

When the scout finds an affordable site, the scout returns to the original flock and dances to indicate the direction of the site and the distance to the site. The worker bees waiting in the swarm will go out to the scout themselves based on the information of the dance, and if they like the proposed site, they will return to the swarm and dance. In addition, the evaluation criteria of the candidate site are that the size of the cavity suitable for the nest, the size and position of the entrance and exit, the state of the wall, etc.

Scouts scattered in all directions insist on a candidate site, and in the flock you will eventually compete for the best candidate site among multiple sites. The scout repeats “ investigation of the candidate site '' and “ dance in the flock '' and increases the number of friends who like the same candidate site as himself, but the number of times one scout goes back and forth between the candidate site and the flock is up to But about six times. Some scouts may cause a scout claiming another candidate to stop dancing with a headbutt or a special warning sound.

Also, scouts surveying the proposed site will always contact other scouts to determine the number of peers under investigation. In general, if 20 to 30 friends are flocking to the same candidate site, the candidate site has won the majority of active scouts, and a certain number of friends are being investigated. The scout will return to the flock and make a humming sound declaring the end of the election. In this way, the new heaven where the new queen has a nest is determined.

If you look at this process, honeybee position determination is a tentative majority decision, but it is a bit wild, such as a head butt, so it is somewhat doubtful that a really good candidate site will be selected. However, the probability that the best candidate site is actually selected from multiple candidate sites is 95%, which is very accurate. A simple and efficient decision-making process involves a non-verbal bee who can make a good candidate by dancing alone.

First, each scout who surveys the proposed site will fold the aptitude of the proposed site into a dance and advertise how good their site is. In fact, this advertisement is a little tricky, and the probability that it can express a candidate site with excellent dance is about 80%. However, scouts who support good candidate sites dance eagerly and try to increase their supporters steadily. The number of times a scout advertising a good candidate site dances about 30 times throughout, but a scout advertising a good candidate site sometimes dances about 90 times in total.

And finally, the last deciding factor is the most experienced 3-5% old bee dance. Older bees have no opinion of their own and copy the dances of scouts near themselves later in the selection process. Older bees support random scouting opinions, but scouts that support good candidates are more likely to dance, so it is more likely that good opinions will be picked up.

"Honeybee Democracy(Honeybee democracy)Economists from the book on the honeybee's decision-making processRobin Hanson"Every individual bee never changes his opinion, but expresses it more often when he speaks out well, and over time the individual bees consolidate their opinions. The selection process concludes with only the last opinion claiming the best candidate site being completed, and importantly, the broad opinions end up without the bees distracting from their beliefs. It will be one. "

Hanson added, “ I don't know how much the behavior of bees applies to humans, but I think this simple and wonderful way is worth keeping in mind, '' he said. He pointed out that there is something to learn about how to form.
