War Psychology: How Personality Predicts Support for Conflict

Six minutes with a psychological test. That's all it takes to predict whether someone will support a war — or condemn violence against civilians. The answer lies less in political beliefs than in personality structure.

🧠 When Childhood Trauma Shapes War Psychology

The 2025 study "Authoritarianism and the Psychology of War" uncovered something disturbing: children who suffered emotional or physical abuse become more likely to support military conflicts as adults. This isn't coincidence. Thousands of British citizens participated in research examining how early experiences shape our views on violence. "People in my family said hurtful or insulting things to me." "They hit me so hard I had bruises or marks." These experiences — not poverty or lack of education — emerged as significant predictors of war support. The psychology here is brutal but simple. Someone who grew up learning that violence solves problems tends to see it as acceptable later.

Hierarchies and Dominance: Who Wants Other Countries "Put in Their Place"

There's a personality type that worships hierarchies. "Social dominance orientation" measures how much someone considers it natural that some groups are superior to others. People with high scores agree with statements like: "Winning is more important than how you play the game" or "Sometimes war is necessary to put other countries in their place."

This isn't random. Those who see the world as a fireplace where the strongest burns the weakest consider war inevitable and justified. In their imagination, there are "inferior groups that need to stay in their place."

⚡ The Psychology of Submission: Why Some People Worship Authority

More disturbing is the finding about "authoritarian submission." This personality type is characterized by excessive respect for power and aggression toward those who challenge official positions. "Our country would be great if we did what the authorities tell us." "Children should learn to obey authorities." These people don't support war because they believe it's right — they support it because authorities support it.

"The more submissive people are to power, the harsher they become toward those who deviate from what authorities prefer"
Yendell & Herbert Study, 2025

The pattern is terrifying: submission upward, aggression sideways and downward.

The Conspiracy Theory Paradox

Surprise? Those who believe in conspiracy theories are less likely to support wars. Research shows their distrust of government and military narratives makes them skeptical of military interventions. This affects how politicians might approach 2026's conflicts. "Make America Great Again" supporters who often believe alternative explanations for events may be harder to convince about the necessity of new military interventions.

🔬 When Sadism Meets War Psychology

The darkest aspect of the research concerns the relationship between "dark" personality elements and war support. Sadistic personality — the tendency to enjoy cruelty and others' pain — proved the strongest predictor of military conflict support.

From the "Dark Triad" (psychopathy, narcissism, machiavellianism), only psychopathy significantly connected to combat support. Narcissism and machiavellianism — despite expectations — showed no statistically significant relationship.

This means war support doesn't come from selfishness or strategic manipulation, but from deeper inclinations toward aggression and dominance.

Violence Against Civilians: The Difference That Matters

Research by Russian scientists Gulevich, Osin, and Chernov in 2022 revealed something critical: there's a difference between supporting military operations generally and approving violence against civilians specifically. Most people who support military operations don't necessarily support violence against civilians. Here, socio-psychological factors like national identification and trust in the political system play roles. But those who approve extreme measures — property theft, destruction of civilian infrastructure, even nuclear weapons use — are mainly individuals with high Dark Triad scores. The mechanism that allows this stance is "moral disengagement": the psychological process that makes harmful behaviors seem acceptable or necessary.

📊 "Reverse Engineering" Personality from War Psychology Views

One of the most fascinating implications of this research is that we can now "reverse engineer" personality. If we know someone's stance toward war, we can guess aspects of their personality — even their childhood.

War Support

Likely abuse history, high social dominance, authoritarian submission

War Opposition

Believes conspiracy theories, low authoritarian submission, high empathy

This has practical implications. If you want to convince someone with authoritarian tendencies against a war, a general's withdrawal will be more effective than intellectuals' arguments.

The Military Dimension: Dangerous Profiles and "Dark Core"

Parallel research on Swedish peacekeepers deployed in Mali revealed a "core of darkness" — a common denominator uniting all negative personality elements. Soldiers with high scores in this core had negative attitudes toward military ethics and higher frequencies of unethical behaviors. The double edge is that these soldiers are sometimes considered "the best killers" — effective in dangerous missions. This creates ethical dilemmas in recruitment: prioritize effectiveness or ethics?

🎯 Frequently Asked Questions

Can these personality characteristics change?

Basic personality elements are relatively stable in adulthood, but attitudes and behaviors can be influenced by education, therapy, and social environment. Early intervention in childhood is more effective.

Does this mean everyone who supports military interventions has a problematic personality?

Not necessarily. Support for military operations can come from logical security reasons, political beliefs, or social pressures. The problem appears mainly when there's support for violence against civilians.

Why does research focus on negative personality elements?

Because understanding the psychological factors that lead to violence support allows us to develop better prevention and intervention strategies. Research shows how to recognize dangerous profiles and take measures. War psychology research doesn't change the fact that conflicts will continue to exist. But it gives us tools to better understand why some people are easily drawn into violence logic — and what we can do about it. In 2026's world, where military conflicts take new dimensions, this knowledge becomes increasingly critical.
