Is a vacant mind really more susceptible to violence?

What science discovers about when the mind has nothing to do?Β 

Idle hands are the devil’s workshop, is that so?

You might have heard this phrase from your parents, your grandparents, or even a teacher asking you to do something. But is boredom really capable of turning an ordinary mind toward devilish actions? Science has been testing this hypothesis, and the answer is more interesting (and more uncomfortable) than the saying suggests.

In 2020, psychologist Stefan Pfattheicher and his team published one of the most comprehensive studies on the topic to date. The conclusion was that inducing boredom in the lab increased people’s sadistic behavior,Β that is, the willingness to cause harm to someone purely for the pleasure of causing it. And not only that, boredom heightened both impulsive aggression, the kind that erupts as a reaction to something, and premeditated aggression, which requires planning.

But the factor everyone fails to explain is that it isn’t boredom that turns people bad, it only works as a trigger that reveals traits that were already there: impulsivity, sadistic tendencies, and difficulty regulating one’s own feelings.

The devil’s workshop exists, but it only opens for business when you already have the tools.

Dangerous for whom?

If boredom is merely a trigger, the question that matters now isn’t “is idleness dangerous?” β€” it becomes “dangerous for whom?”

A study recently published in Science Direct confirmed that sensation seeking is the link connecting boredom to aggression. The logic: boredom signals a lack of stimulation and meaning, so the person seeks out high-arousal experiences to compensate, and this reduces inhibitory control and pushes toward more impulsive and risky behaviors, including aggressive ones.

In other words: it isn’t the emptiness itself that produces violence, but rather how the mind chooses to fill it. Aggression becomes one of the available ways to fill that void.

But is an empty mind entirely bad? As the studies have already concluded, idleness isn’t dangerous for everyone, and,Β if boredom is ambiguous, what happens when we experience it from the other side?

When emptiness creates instead of destroying

The explanation is quite simple: when the brain is free from a task, it takes the opportunity to “tidy the house”, and sometimes this organizing process generates new combinations. So the answer is yes, the same mental state (boredom, lack of stimulation) can produce opposite outcomes, aggression or creation.

That’s why boredom is neither good nor bad by nature β€” it’s just a signal that “what you’re doing right now isn’t giving you satisfaction or meaning. What you do with that signal is what determines whether the outcome is good or bad.

Putting in simpler words: the bored person receives the signal “I need something more stimulating.” From there, they can decide to do all sorts of things: exercise, read, create something, or, in the worst case, seek stimulation through aggression or risk-taking.

In fact, studies show that if you’re trying to solve a problem at work, or even trying to develop a scientific thesis, you should try letting your mind get bored, unstimulated, for a while. That’s because when the brain isn’t focused on a task, it tends to “rummage through” more possible alternatives to a problem, as if, without a fixed task holding its attention, it becomes more willing to consider non-obvious paths.

Now, next time boredom strikes, maybe the right question isn’t “how do I make this stop?” but “what is this empty mind trying to tell me?”. Because, in the end, the devil doesn’t live in the emptiness: it lives in the rush to fill it without thinking.
