5 lessons from insects to help you make better decisions
Sometimes it is hard to make a good decision, and animals can teach us how to do it better.
Ants work as a team, and the best path to food becomes clear over time without one leader telling anyone what to do.
Honeybees listen to many different opinions before choosing a new home.
Locusts show that it is okay to pause and think instead of rushing.
Cockroaches teach us that having different personalities in a group can actually help it decide faster.
Fruit flies show that how we feel, like being hungry or stressed, can change the choices we make.
When faced with a hard choice, it helps to gather different opinions.
It also helps to understand our own mood before deciding.
Taking a break can make the right answer clearer.
The animal kingdom shows that careful, patient group thinking often works best.
Ants show that efficient collective decision-making can emerge without centralised control, as shorter routes get reinforced through stronger pheromone trails.
Honeybee scouts use a 'waggle dance' to share information about potential nesting sites, and the colony decides once enough bees support one location.
Kit Yates found that pausing and allowing abstention helped groups of locusts change direction and helped humans reach decisions more 'quickly and cleanly'.
Isaac Planas-Sitjà found that cockroach groups with a mix of bold and timid personalities made collective decisions faster than uniform groups.
Fruit flies weigh risks, rewards and their own condition, taking longer on similar choices and changing decisions when hungry or stressed.

“The main lesson… is that efficient collective decision-making can emerge without centralised control”

“With fewer active votes in play, the same small nudge – a brief local cluster moving the other way, a noisy bit of information, a couple of people switching allegiance – produces a larger proportional effect on the group's direction”
