Why Politicians Act the Way They Do
Political behaviour is shaped less by ideals and more by incentives. This page explains how elections, media, and institutions influence decision-making, and why people in politics respond predictably to the pressures they face.
Common Misconception
A common belief is that political outcomes are mainly driven by personal values or honesty.
While values matter, behaviour is often shaped more strongly by incentives. People tend to respond to rewards, risks, and pressures in their environment, regardless of intent.
Why It Matters
Understanding incentives helps explain why similar patterns appear across different governments and parties.
It also helps separate individual behaviour from systemic behaviour. Many political frustrations are better explained by incentives built into the system than by individual failings.
How It Works
Political incentives operate across several overlapping systems.
Elections: Winning elections is often based on short-term popularity during the electoral campaign, visibility, and focusing on simple issues. This can encourage politicians to promise quick perceived benefits, even if long-term costs are higher.
Media: Attention in the media is often achieved through initiating conflict, simplicity of communication, and strong, unambiguous statements. This can push political behaviour towards simplicity rather than nuance.
Institutions: Rules, procedures, and traditions shape what is possible. Institutional incentives reward compliance, seniority, and caution, often slowing change.
Together, these pressures influence how politicians communicate, compromise, and prioritise.
A Practical Example
Governments often set measurable targets in response to public concern. For example, if long waiting times for NHS appointments are seen as a major issue, reducing those waits may become a political priority.
Once a target is set, behaviour adjusts around it. Managers and clinicians may be encouraged to increase the number of appointments offered. This can successfully reduce waiting lists.
However, the same incentive can create pressure to shorten appointments or prioritise simpler cases. This may improve headline figures while placing strain on staff or affecting the quality of care.
The outcome is not the result of bad intentions, but of incentives focusing attention on what is measured.
Another Practical Example
Economic incentives operate in a similar way.
In the UK, chancellors often work within a fiscal rule designed to demonstrate economic prudence. Broadly speaking, this involves showing that public finances are on a sustainable path over a set time horizon, commonly around five years. One measure looks at whether borrowing or debt is falling by the end of that period.
Once such a rule exists, behaviour adjusts around it.
A government may have more freedom to borrow earlier in the period, while ensuring that spending or borrowing is reduced in the final year so the target is met. This can satisfy the rule, even if overall borrowing remains high for most of the period.
The incentive is not necessarily to minimise borrowing at all times, but to meet the specific measure at the specific point it is assessed.
Again, this does not imply deception or bad faith. It shows how rules shape behaviour. What gets measured becomes what matters.
Behavioural Effects
Incentives can produce predictable outcomes.
- Short-term thinking can crowd out long-term planning.
- Risk-avoidance can discourage experimentation.
- Polarisation can increase when cooperation is not rewarded.
These patterns emerge even when individuals have good intentions.
Key Points
- Incentives shape behaviour more than stated values.
- Political systems reward some actions and discourage others.
- Targets influence outcomes, both positive and negative.
- Media and elections affect priorities and tone.
- Understanding incentives reduces misplaced blame.
Myth Buster
Bad outcomes do not always result from bad people. Often they result from incentives that push behaviour in unhelpful directions.
The core idea is simple: incentives, rather than intentions, drive behaviour.
