Moral License Effect: What it is and How it Affects Our Actions

The moral license effect is a fascinating psychological phenomenon that explains why people sometimes make unethical choices after doing something good. At first glance, it sounds contradictory—shouldn’t doing good make us more ethical? But research shows that our minds often “balance out” our behaviors, giving ourselves internal permission to act in ways that contradict our values.

This subtle yet powerful effect can influence our daily decisions, from what we eat to how we treat others, and even how we vote or shop. Understanding how moral licensing works helps us avoid self-sabotage, build stronger habits, and make decisions that truly align with our values.

What Is the Moral License Effect?

The moral license effect (also known as moral self-licensing) refers to the psychological tendency to justify immoral or questionable behavior after engaging in something that affirms one’s moral identity. In short, doing something good gives us permission to do something bad—or at least not so good—right afterward.

This doesn’t mean people are bad or manipulative. It means that our brains often try to “keep the moral score”. Once we feel we’ve earned enough “good person” points, we may unconsciously relax our standards or feel entitled to indulge.

Example 1: After donating to a charity, a person might later justify yelling at a coworker or cheating on their diet. “I’ve been good—I deserve this,” is often the internal logic.

Example 2: Let’s take a very simple example to understand it: every time we have a hamburger with ketchup and fries (very caloric products), we also order a Diet Coke to accompany it.

This addition of Coca-Cola “counteracts”, for us, the negative consequences of having eaten so much junk food, because we “compensate” for it with Diet Coca-Cola. From a rational point of view, this may seem quite absurd, but through the moral license effect, we give ourselves that license to act “badly” or immorally.

Where Did the Concept Come From?

The term emerged from social psychology research in the early 2000s. Studies by researchers like Benoît Monin and Dale Miller showed that people who had recently made ethical decisions were more likely to make less ethical ones shortly after.

This idea is closely tied to the self-concept: people want to maintain a positive moral identity. Once that identity feels “secured,” they are more willing to engage in behaviors that would normally conflict with it.

Common Examples of the Moral License Effect in Daily Life

This effect appears in many everyday scenarios—often without us realizing it.

1. Health and Fitness

After a long workout, people may feel justified in eating an unhealthy meal, thinking they’ve “earned” it.

2. Environmentally-Friendly Behavior

People who use reusable bags might be more likely to buy junk food or use plastic in other situations, believing they’ve “done their part.”

3. Workplace Conduct

An employee who works late or helps a colleague may later cut corners on another task without feeling guilty.

4. Social Interactions

Someone who supports a cause or advocates for diversity may later feel licensed to make a stereotypical joke or overlook unethical behavior in others.

5. Consumer Behavior

After making an ethical purchase (e.g., fair-trade coffee), shoppers may reward themselves with luxury items or unnecessary spending.

In all these cases, the good act functions as a “moral buffer,” protecting the person from guilt over the next choice.

Why Does Moral Licensing Happen?

The root cause is our desire to maintain a positive self-image. When we act in a way that aligns with our values, we feel morally secure. But instead of building on that behavior, the brain sometimes interprets it as a license to loosen up.

Some key psychological mechanisms behind it include:

• Moral balancing: Our brain tries to keep a moral equilibrium. Too much “good” may feel exhausting.
• Compensatory ethics: People try to make up for bad deeds with good ones—and vice versa.
• Self-justification: After doing good, we believe we’ve earned flexibility.

How the Moral License Effect Can Be Harmful

While moral licensing can be harmless in small doses, it can undermine long-term goals and values if left unchecked. Some dangers include:

• Sabotaging healthy habits (diet, exercise, budgeting)
• Inconsistent ethical behavior (being kind one day, aggressive the next)
• Manipulating moral credit as an excuse (e.g., “I’ve done enough for others”)
• Reinforcing bias or double standards
• Reducing accountability for poor choices

It can also lead to a false sense of moral superiority, where individuals feel they are “better” people due to one or two good actions, while ignoring patterns of negative behavior.

How to Avoid the Moral License Trap

Becoming aware of this effect is the first step. To minimize its impact:

1. Focus on Identity, Not Just Actions

Instead of seeing goodness as a transaction (“I did good, now I get a pass”), shift toward an identity-based approach:
“I am the kind of person who consistently makes healthy or ethical choices.”

2. Track Your Motivations

Ask yourself: “Am I making this decision because it’s right, or because I think I’ve earned it?”

3. Avoid Moral Scorekeeping

Resist the urge to tally your good deeds. Morality isn’t a point system—it’s a lifestyle.

4. Set Clear Goals and Values

Having clear personal values helps guide decisions consistently, even after moments of pride or success.

5. Use Success as a Foundation, Not an Excuse

Let good behavior build momentum for more good behavior, rather than serve as a stop sign.

Moral Licensing vs. Cognitive Dissonance

It’s important to distinguish between moral licensing and cognitive dissonance.

• Moral licensing is preemptive—we do good, then feel entitled to do bad.
• Cognitive dissonance is reactive—we do something that conflicts with our values, and feel discomfort afterward.

Both involve how we manage internal tension between actions and self-image, but moral licensing justifies unethical behavior, while cognitive dissonance tries to resolve it.

As a reflection: a form of self-deception?

An interesting reflection that arises around this effect is the one that links it to a form of self-deception. Thus, as a result of the previous example (the gym and the pastry shop), the following question may arise… is the moral license effect a form of self-deception? Well, probably, and on many occasions, yes. Through this effect, our mind “self-justifies” and gives itself that license to act badly. Each one acts as he wants, as he knows or as he can, nothing to say….

But can we justify that decision by the fact that we have acted well in the past? Probably not. What does one thing has to do with the other? Nothing… we act the way we act because we want to. That later we justify things as it suits us, is another story…

So, the moral license effect is a phenomenon that can help us understand why we often commit immoral acts without feeling bad about it (logically, these acts can be on a small scale or on a large scale…), and our mind (and if we go deeper, also our conscience) gives us a certain obstacle, a certain margin when it comes to sin…

This makes us feel calmer, with fewer regrets, and more likely to act “badly” (immorally) in the future.

FAQs about Moral License Effect

What is the moral license effect in psychology?

The moral license effect describes how people justify questionable actions after doing something good. It’s like giving yourself permission to act badly because you’ve earned moral credit.

Is moral licensing always bad?

Not necessarily. It can be harmless in small ways, like treating yourself after a workout. But over time, it can lead to inconsistencies and self-sabotage if it becomes habitual.

How do I know if I’m using moral licensing?

If you catch yourself thinking “I deserve this because I was good earlier,” or if your behavior swings between extremes, you may be under the influence of moral licensing.

Can moral licensing affect relationships?

Yes. People may act kindly in one situation, then feel justified in being distant or selfish later—especially if they feel they’ve “earned” the right. It can create imbalanced dynamics.

How can I stop moral licensing from affecting my habits?

Build habits based on identity, not rewards. Remind yourself, “I do this because it aligns with who I want to be,” not because you’ve met a quota of goodness for the day.
