Tragedy of the Commons

what it means
When a shared resource is open to everyone, individuals acting in their own interest tend to overuse and ruin it.
How Tragedy of the Commons works
Each herder gains fully from adding one more cow but shares the cost of overgrazing with everyone. The rational individual choice adds up to collective ruin.
Inside companies, shared resources — a shared budget, a common inbox, the brand's reputation, a shared customer list — suffer the same fate without clear rules and ownership.
where it comes from
Described by William Forster Lloyd in 1833 using the example of shared grazing land, and popularised by ecologist Garrett Hardin in a 1968 article in Science. Elinor Ostrom later won the 2009 Nobel Prize in economics for showing how communities can manage commons successfully.
Tragedy of the Commons examples in business
Email lists
Every team emails the same customer list ‘just once more’ until unsubscribes soar.
Shared services
Free internal design support is swamped with low-priority requests until a simple request system is introduced.
Markets
Overfishing, groundwater depletion, and traffic congestion all follow the same pattern.
How to apply it
- 1Identify shared resources in your business that nobody owns.
- 2Assign an owner with authority to set usage rules.
- 3Introduce light limits or pricing (quotas, calendars, internal charge-backs).
- 4Make usage visible so overuse is noticed early.
common misreading
Ostrom showed it is not inevitable — communities with clear rules, monitoring, and local ownership often manage commons well.
ask yourself
Which shared resource in your company is being slowly overused because nobody owns it?
