Scientific American’s November 2025 article by Elizabeth Svoboda treats morality less as a fixed character trait than as a direction of travel. The piece argues that people can become accustomed to dishonesty, cruelty or courage in much the same way they become accustomed to other repeated experiences. A small first step matters because the brain learns from it. It can make the next compromise easier, or it can make the next act of integrity feel more possible.

The article opens with Texas entrepreneur Chris Bentley, whose oil-and-gas leasing company unraveled after he tried to hide an initial mistake in letters to landowners. What began as a cover-up became a much larger fraud. Svoboda uses his story to show how ethical collapse often starts before anyone thinks of themselves as corrupt. A person under pressure reframes a dishonest act as a temporary fix, a lesser evil or a necessary sacrifice for employees, investors or some larger goal. Once that framing takes hold, the moral boundary shifts.

How Bad Choices Become Easier

Svoboda’s core claim is that repeated wrongdoing can dull the emotional warning signals that initially make it feel repellent. The first lie, theft or betrayal may provoke disgust, fear and self-reproach. But experiments suggest that the emotional response can fade when people repeat the act. In one study, people who lied repeatedly in a game tended to tell larger lies later, while activity in the amygdala, a brain region tied to emotional arousal and threat, decreased. The implication is not that the amygdala is the morality center. It is that moral decisions involve a distributed system of emotion, reward, fear, social pressure and deliberation.

That broader system includes regions such as the anterior insula, which is involved in disgust; the prefrontal cortex, which helps regulate instinctive reactions and weigh options; the anterior cingulate cortex, which participates in conflict and emotion management; and reward-related circuitry that helps determine what a choice seems to offer or cost. Moral judgment, in this account, is not a pure act of logic. It is a negotiation among bodily revulsion, fear of consequences, social belonging, personal reward and the stories people tell themselves about why they are doing what they are doing.

Pressure makes that negotiation worse. Bentley describes a business environment in which mistakes felt intolerable, and Svoboda connects that panic to research showing that fear and stress can impair higher-order thinking. The same pattern appears in institutional scandals. Former WorldCom employee Betty Vinson initially recoiled from fraudulent accounting adjustments, but repeated requests from superiors and the apparent normality of the scheme around her helped make the behavior routine. Once a workplace treats deception as ordinary, truth-telling can begin to feel like the abnormal act.

Courage Uses The Same Machinery

The article’s more interesting turn is that moral momentum can also run in the other direction. Courage, honesty and principled refusal can become easier through repetition. Svoboda compares moral courage to experiments in which people afraid of snakes used controls to bring a snake closer while lying in a scanner. When participants chose to approach what frightened them, brain regions involved in emotion regulation became more active, while threat-related activity diminished. The lesson is not that fear disappears. It is that people can practice acting while fear is still present, and the brain can adapt to that pattern too.

Svoboda develops this idea through the story of former Capitol police officer Aquilino Gonell. His earlier military experience, family values and repeated acts of public truth-telling after January 6 helped him keep speaking despite threats and injuries. His case functions as the mirror image of Bentley’s: repeated action did not numb him to wrongdoing but strengthened his identity as someone who tells the truth under pressure.

This symmetry is the article’s strongest insight. Moral failure and moral courage are not separate species of behavior. Both are shaped by habituation, reward, identity and social feedback. People repeat what begins to feel possible, defensible and rewarding. A corrupt act can become easier because it spares embarrassment, protects status or postpones collapse. A courageous act can become easier because it brings coherence, self-respect and a sense of meaning.

Building Better Defaults

The practical conclusion is that the beginning of a moral trajectory deserves special attention. People and institutions should not wait until misconduct has become routine before acting. Clear advance rules, credible penalties for early violations and workplace cultures that make admitting mistakes safe can prevent small compromises from becoming large ones. Ethical leadership matters because it changes what a group treats as normal. So does peer behavior: people are more likely to resist wrongdoing when they see others resist it first.

The article also points to individual tools. Mindfulness and perspective-taking may help people step outside immediate self-interest and consider the harm a choice imposes on others. Psychologists’ idea of a “heroic imagination” asks people to rehearse in advance what they would do when pressured to betray a core value. That rehearsal matters because moral clarity is hardest to summon in panic.

Svoboda’s takeaway is sober but not fatalistic. The brain’s adaptability makes people vulnerable to gradual corruption, but the same plasticity gives them a route toward integrity. Character is not merely what someone possesses before a crisis. It is also what repeated choices train the mind to find acceptable, rewarding and eventually natural.
