In an anthill, some ants carry food and build, while others just eat and reproduce. This isn't just laziness: it's two distinct types of ants. Workers are smaller, while freeloaders are larger. If freeloaders become too numerous, the colony falls apart, like a communal kitchen where nobody washes the dishes.

In urban planning, Braess's paradox is well known: adding a new road to a transport network can worsen traffic rather than ease it. For a long time, it was explained by the selfish behavior of drivers, each seeking personal gain. However, ant colonies, acting as a single coordinated superorganism without personal interests, exhibit the same trap.
