Organisational behaviour isn’t one science. It’s a borrowed one. It takes ideas from psychology, sociology, and a handful of other fields, then stitches them together to answer one question: why do people act the way they do at work?
The main disciplines contributing to organisational behaviour (OB) are psychology, sociology, social psychology, anthropology, and political science — with economics and medicine adding more. Each one hands OB a different piece of the puzzle, from how a single employee thinks to how entire cultures and power structures shape a workplace.
Why Organisational Behaviour Borrows From Other Fields
Organisational behaviour is the study of how people act inside organisations — individually, in groups, and as a whole. But human behaviour is far too complex for any single field to explain. So OB does something smart: it pulls the best insights from several established sciences and applies them to the workplace.
That’s what makes it a genuinely applied, multidisciplinary field. Understanding where its ideas come from isn’t academic trivia — it’s what lets you see why OB looks at a problem the way it does. Here are the disciplines doing the heavy lifting.
The 5 Core Contributing Disciplines
1. Psychology
Psychology is the biggest contributor by far. It’s the science of individual behaviour — and it works at the individual level. From psychology, OB takes the tools to understand personality, perception, motivation, learning, attitudes, emotions, and job satisfaction. Nearly everything OB says about a single employee traces back here. If you want to know why one person thrives and another checks out, you’re asking a psychology question.
2. Sociology
If psychology explains the individual, sociology explains the group. It’s the study of people in relation to their social environment. OB borrows sociology’s understanding of group dynamics, teams, organisational structure, culture, communication, power, and conflict. Anything involving how people behave together — how teams form, how norms take hold — leans on sociology.
3. Social Psychology
Social psychology is the bridge between the first two — a blend of psychology and sociology that studies, as Encyclopaedia Britannica puts it, “the behaviour of individuals in their social and cultural setting.” It’s where OB gets its grip on the hardest workplace challenge of all: managing change. Reducing resistance, shaping attitudes, building trust, understanding how groups influence a person’s decisions — that’s social psychology at work.
4. Anthropology
Anthropology is the study of humankind and its cultures. Its gift to OB is a deep understanding of culture and environment — the values, rituals, and shared assumptions that quietly run an organisation. Why does one company feel formal and another feel like a family? Why do two national offices of the same firm behave completely differently? Those are anthropology questions, and they matter more than ever on global teams.
5. Political Science
People often forget this one, but every organisation is a political system. Political science studies behaviour in that context — power, authority, politics, and conflict. From it, OB understands how power gets distributed, how people compete for resources and influence, how coalitions form, and how office politics really work. Ignore it, and half of what happens in a workplace makes no sense.
Two More Disciplines That Contribute
Beyond the core five, two other fields feed into modern OB:
- Economics — shapes how OB thinks about decision-making, incentives, labour markets, and how people weigh costs and benefits at work. It’s why reward systems and rational-choice models sit inside the field.
- Medicine (medical science) — informs OB on stress, employee wellbeing, occupational health, and ergonomics. As burnout and mental health move to the centre of work, medicine’s contribution keeps growing.
Which Discipline Works at Which Level?
Here’s the shortcut that ties it all together — and the part most explanations skip. The disciplines line up neatly with the level of behaviour they explain:
- Individual level → Psychology (and medicine for wellbeing)
- Group level → Social psychology and sociology
- Organisation-system level → Sociology, anthropology, political science, and economics
Read OB this way and it stops feeling like a random pile of theories. Each discipline is simply zoomed in at a different distance — from one person, to a team, to the whole organisation. It’s the same logic behind how perception and behaviour scale up from the individual to the group.
Why This Multidisciplinary Mix Matters
This isn’t just a list to memorise for an exam. The multidisciplinary nature of OB is exactly what makes it useful. A workplace problem is never only psychological or only political — it’s usually a tangle of all of them at once.
Take a team that keeps missing deadlines. Psychology asks whether individuals are motivated. Sociology asks whether the group’s norms are broken. Social psychology asks whether people are resisting a recent change. Political science asks whether a power struggle is getting in the way. Only by drawing on all of them do you get the full picture — which is why understanding these disciplines makes you sharper at spotting the real causes of conflict and the everyday challenges of organisational behaviour. It’s also foundational to what good management actually does.
Frequently Asked Questions
What are the disciplines contributing to organisational behaviour?
The five core disciplines are psychology, sociology, social psychology, anthropology, and political science. Economics and medicine also contribute, giving OB its multidisciplinary character.
Which discipline contributes the most to OB?
Psychology. As the science of individual behaviour, it supplies most of what OB knows about motivation, perception, personality, learning, and job satisfaction — making it the single biggest contributor.
Why is organisational behaviour called multidisciplinary?
Because it draws its concepts from several separate sciences — psychology, sociology, anthropology, political science, economics, and more — rather than standing on one field alone. Human behaviour at work is too complex for any single discipline to explain.
What is the difference between psychology and sociology in OB?
Psychology studies the individual — one person’s motivation, personality, and perception. Sociology studies the group — teams, structure, culture, and how people behave together. OB needs both.
One Field, Many Lenses
Organisational behaviour earns its power by refusing to pick a single lens. It takes the individual focus of psychology, the group focus of sociology, the cultural depth of anthropology, and the hard truths of political science — and points them all at the same target: people at work.
So the next time a workplace problem baffles you, run it through the disciplines. Is this about the person, the group, the culture, or the power? Nine times out of ten, it’s more than one — and knowing which lenses to reach for is what turns a confusing situation into a solvable one.
