MASS SHOOTINGSWhy Do Mass Shooters Kill? It’s About More Than Having a Grievance

The year 2023 is still young, and already there have been at least 146 mass shooting events in the U.S. on record, including the killing of five people in a Louisville, Kentucky, bank that the shooter livestreamed. There were 647 mass shootings in 2022 and 693 in 2021, resulting in 859 and 920 deaths, respectively. Since 2015, over 19,000 people have been shot and wounded or killed in mass shootings. In the wake of most shootings, the news media and the public reflexively ask: What was the killer’s motive?

An acutely troubling aspect of life in contemporary America is the growing proliferation of mass shootings that claim thousands of innocent lives year after painful year and make everyone feel unsafe.

The year 2023 is still young, and already there have been at least 146 mass shooting events in the U.S. on record, including the killing of five people in a Louisville, Kentucky, bank that the shooter livestreamed. There were 647 mass shootings in 2022 and 693 in 2021, resulting in 859 and 920 deaths, respectively, with no respite in sight from this ghastly epidemic. Since 2015, over 19,000 people have been shot and wounded or killed in mass shootings.

In the wake of most shootings, the news media and the public reflexively ask: What was the killer’s motive?

As a psychologist who studies violence and extremism, I understand that the question immediately pops to mind because of the bizarre nature of the attacks, the “out-of-the-blue” shock that they produce, and people’s need to comprehend and reach closure on what initially appears to be completely senseless and irrational.

But what would constitute a satisfactory answer to the public’s question?

Media reports typically describe shooters’ motives based on specific individual details of the case, on their “manifestos” or social media postings. These generally list insults, humiliations or rejections – by co-workers, potential romantic partners or schoolmates – that a perpetrator may have suffered. Or they may cite alleged threats to the shooter’s group from some imagined enemy such as Jews, people of color, Muslims, Asians or members of the LGBTQ+ community.

Though perhaps informative about a given perpetrator’s way of thinking, I believe these motives are too specific. Each shooter’s life story is unique, yet the growing number of mass shootings suggests a general trend that transcends personal details.

Quest for Significance
Perhaps surprisingly, the general motive that drives mass shootings is a fundamental human need. It is everyone’s quest for significance and a feeling that their life matters.

That need gets activated when someone feels the loss of significance, the sense of being slighted, humiliated or excluded, but also when there is an opportunity for a gain in one’s sense of significance, being the object of admiration, a hero or a martyr in other people’s eyes.
