Structural Functionalism for the MCAT- Review
What Is Structural Functionalism?
Structural functionalism is a sociological theory that views society as a complex system whose parts work together to promote stability and solidarity. Think of it like the human body: every organ has a job, and when one part malfunctions, the whole system feels it.
On the MCAT, you'll encounter this framework primarily in the Psychological, Social, and Biological Foundations of Behavior section. It's not just abstract theory—it directly explains why societies develop norms, institutions, and hierarchies.
Core Concepts You Need to Know
Social Institutions
Institutions like family, education, religion, and government each serve specific functions that keep society running. The family, for example, socializes children and provides emotional support. Education transmits knowledge and sorts individuals for future roles.
Manifest vs. Latent Functions
Manifest functions are the intended, obvious consequences of a social action. Latent functions are the hidden, unintended consequences.
Example: College has a manifest function (education) and latent functions (networking, signaling competence to employers, finding a spouse).
Social Solidarity
Durkheim argued that societies develop mechanical solidarity (based on similarity, common beliefs) or organic solidarity (based on interdependence and specialization). Industrial societies rely on organic solidarity—everyone depends on everyone else's specialized skills.
Social Equilibrium
Society naturally tends toward equilibrium. When one part of the system changes, other parts adjust to restore balance. This is why technological changes often trigger cultural pushback.
Key Theorists and Their Contributions
You'll need to recognize these names and connect them to their core ideas.
| Theorist | Core Idea | Key Concept |
|---|---|---|
| Émile Durkheim | Society has external facts that constrain individuals | Social facts, mechanical vs. organic solidarity, anomie |
| Talcott Parsons | Society is a system of interconnected parts | AGIL paradigm (Adaptation, Goal attainment, Integration, Latency) |
| Robert K. Merton | Functions can be positive, negative, or absent | Manifest/latent functions, dysfunction, eufunctions |
| Herbert Spencer | Societies evolve like organisms | Social Darwinism, "survival of the fittest" applied to societies |
How Structural Functionalism Appears on the MCAT
This theory shows up in three main ways:
- Passage-based questions: A sociology passage will describe a social phenomenon, and you'll need to identify which function is being served
- Concept application: Questions ask you to predict how disturbing one social institution affects others
- Theorist identification: You'll need to match theorists to their specific contributions
The test loves the manifest/latent distinction. If you see a question about unintended consequences of a social norm or institution, Merton's framework is your answer.
Study Guide: How to Get This Down
Here's how to actually learn this material instead of just memorizing it:
Step 1: Master the Function Framework
For any social institution or behavior, ask yourself:
🔹 What problem does this solve for society?
🔹 Who benefits, and how?
🔹 What would happen if this disappeared?
This trains you to think functionally, which is exactly what the MCAT expects.
Step 2: Memorize the Theorist-Concept Pairs
You don't need biographical details. You need:
• Durkheim = social facts, anomie, solidarity types
• Merton = manifest/latent functions, dysfunction
• Parsons = systems theory, AGIL
• Spencer = social Darwinism (be skeptical of this one)
Step 3: Practice Passage Analysis
Find practice passages about social institutions. Before answering questions, identify:
• What institution is being discussed?
• What function is being served?
• Is the passage describing manifest or latent functions?
This takes practice. Do 10-15 passages and the pattern becomes obvious.
Step 4: Watch for Dysfunction Questions
Merton's concept of dysfunction is frequently tested. A dysfunction is a consequence that reduces societal stability. If a passage describes social problems, it's probably asking about dysfunctions.
Common MCAT Traps to Avoid
- Don't confuse structural functionalism with conflict theory. Functionalists see society striving for stability. Conflict theorists see constant struggle between groups.
- Don't assume all social practices are "functional." Merton explicitly allowed for dysfunctions—things that harm society.
- Don't overcomplicate Spencer. He's a historical figure, but his "social Darwinism" is generally criticized, not endorsed.
Quick Reference
Structural functionalism in one sentence: Every part of society exists because it serves a function that contributes to social stability.
The key question to ask: What purpose does this social pattern serve?
Remember: Manifest = intended, Latent = unintended. Merton gave us this distinction, and the MCAT uses it constantly.
