Emergent properties are features of a whole that none of its parts has on its own: a traffic jam is not a property of any one car, and life is not a property of any one molecule. They arise from how the parts interact. The idea took shape with the nineteenth-century British Emergentists: John Stuart Mill argued in 1843 that living things show effects that do not simply add up, and G. H. Lewes first used the term “emergence” for the position in 1875.
Emergence needs components that influence each other, not just sit side by side.
02
Non-additive effects
The whole is not the sum of the parts: interactions create effects that adding up parts would miss.
03
Levels of description
Each level, from molecules to cells to organisms, can need its own concepts and laws.
04
Hard to predict
Emergent behaviour is often difficult to forecast from the parts, which is both its power and its risk.
Where you see it today
Emergent abilities in AI
Researchers described “emergent abilities” in large language models: abilities absent in smaller models that appear in larger ones and cannot be predicted by extrapolation (Wei et al., 2022). Others argue many of these jumps reflect the choice of metric, and look smooth under continuous measures (Schaeffer et al., 2023). The debate is open.
Multi-agent behaviour
In a simulated town of language-model agents, a single agent’s plan to throw a party produced invitations, dates and coordinated attendance that no one scripted (Park et al., 2023). Agent systems can produce collective behaviour no single agent was given.
Testing systems, not parts
Because emergent behaviour lives in the interactions, a system of agents can fail even when every agent passes its own test. That is why agent workflows need end-to-end evaluation, not only checks on each component.
Organisations and markets
Culture, prices and traffic patterns are emergent: no one sets them directly. Managers shape them indirectly through incentives, rules and structure.
Emergent properties vs related ideas
Emergent property
Core claimThe whole has features its parts lack
ExampleWetness of water; a traffic jam
Reductionism
Core claimWholes are explained by their parts
ExampleChemistry explained by physics
Weak emergence
Core claimNew behaviour that follows from the parts but is hard to predict
ExampleFlocking from simple bird rules
Strong emergence
Core claimNew properties not deducible even in principle from the parts
ExampleDebated cases such as consciousness
Fallacy of composition
Core claimAssuming the whole has the properties of its parts
Example"Each agent is safe, so the system is safe"
How to use it
Test agent systems end to end; component tests alone miss emergent failures.
Look for the interaction that produces a behaviour before blaming a single part.
Change rules and incentives when you want different collective behaviour; you rarely control it directly.
Be cautious with claims of sudden AI abilities; check whether the metric is all-or-nothing.
Monitor live systems for behaviour no one designed, and have a way to stop it.
The Business Engineer lens
As companies move from single models to systems of agents, value and risk increasingly sit in how the parts interact. The Business Engineer’s view is that agentic work has to be designed and measured as a system, because that is where emergent gains and failures show up.
Features of a whole system that none of its parts has on its own, arising from how the parts interact.
Where does the idea of emergence come from?
From the nineteenth-century British Emergentists: John Stuart Mill described non-additive effects in 1843, and G. H. Lewes first used the term emergence for the position in 1875.
Do large language models have emergent abilities?
Some researchers report abilities that appear only at scale; others argue many of these jumps come from how the abilities are measured. The question is still debated.
Why do emergent properties matter for AI agents?
Systems of agents can behave in ways no single agent was designed to, so they need to be tested and monitored as whole systems.
