Coalitions and Policy Change
PET Basics
Advanced PET
100

This is the primary unit of analysis in the Advocacy Coalition Framework.

What is a policy subsystem?

100

These are fundamental values about society and rarely change.

What are deep core beliefs?

100

Policies reflect the beliefs of these groups when they gain influence.

What are advocacy coalitions?

100

PET explains why policy is usually stable but occasionally experiences this type of dramatic change.

What is punctuated equilibrium?

100

Policies are handled by expters with low attention and small changes at this level of politics.

What are policy subsystems?

200

ACF assumes individuals make decisions with limited information, time, and cognitive ability.

What is bounded rationality?

200

These beliefs define coalitions within a specific policy area.

What are policy core beliefs?

200

These actors help mediate between coalitions and facilitate compromise.

Who are policy brokers?

200

This type of feedback stabilizes policy and maintains the status quo.

What is negative feedback?

200

This level of politics involves high attention, media, and large-scale policy change.

What is macropolitics?

300

Rather than focusing on who has power, ACF focuses on this as the basis for group formation.

What are shared beliefs (especially policy core beliefs)?

300

These are the most flexible beliefs and relate to implementation details.

What are secondary aspects?

300

These events occur outside the subsystem and can shift power and open policy windows.

What are external events?

300

This type of feedback amplifies change and leads to rapid policy shifts.

What is positive feedback?

300

This distribution shows many small changes and a few very large changes in policy.

What is a leptokurtic distribution?

400

This type of information helps actors understand cause-and-effect but is filtered through belief systems.

What is scientific and technical information?

400

In ACF, coalitions are primarily formed around this level of belief.

What are policy core beliefs?

400

These long-term background conditions (like institutions and culture) shape what policies are possible.

What are stable parameters?

400

These institutional barriers slow policy change and create long periods of stability.

What is friction?

400

This occurs when disproportionate attention or resources are given to a policy, often beyond its effectiveness.

What is a policy bubble?

500

ACF argues that to truly understand policy change, researchers must study policy over this time frame.

What is a long-term perspective (10+ years)?

500

When evidence contradicts beliefs, actors tend to change this level rather than their core beliefs (think “lucky socks”).

What are secondary aspects?

500

This process describes how actors adjust strategies and understanding over time without changing core beliefs.

What is policy-oriented learning?

500

This concept describes stable relationships that control problem definition and limit participation.

What are policy monopolies?

500

According to PET’s disaster model, this process leads to major failures when small problems are ignored over time.

What is error accumulation?
