Understanding Trump’s Appeal Through Fear, Identity, and the End of Globalization

When Donald Trump won the presidency in 2016, like many, I was stunned. When he lost in 2020, I believed the country had turned the page. His comeback in 2024 was unprecedented and baffling. To make sense of it, I turned to trusted sources: science, sociology, and history.
Fear and the Conservative Brain
Part of the answer lies in the way our brains are wired. Neuroscientists Daniel Z. Lieberman and Michael E. Long, in The Molecule of More, explain how dopamine, the brain’s chemical of desire and motivation, drives human behavior. It governs our engagement with the future, pushing us to seek, plan, and imagine.
Liberals, they argue, tend to be more dopamine-driven, drawn to change, exploration, and progress. Conservatives, by contrast, lean more on the “here-and-now” chemicals like serotonin and oxytocin that foster connection, stability, and contentment with what exists. Complementary findings show that conservatives have stronger activity in brain regions linked to threat detection, like the amygdala, explaining their heightened sensitivity to danger and preference for order.
Trump speaks directly to this psychology. He doesn’t offer a hopeful future, he offers protection from a fearful one. His message is not about building something new but defending what’s being lost. For brains wired toward security, this is a powerful appeal.
Alienation and the Deep Story
Sociologist Arlie Russell Hochschild offers another insight in Strangers in Their Own Land. She embedded herself in conservative communities in Louisiana, trying to understand what she called the “deep story” of the American right. It wasn’t just about policy; it was about identity.
Many of these communities suffer from pollution, poor infrastructure, and economic decline, yet they resist environmental regulation and progressive reforms. Why? Because they feel insulted, ignored, and stereotyped. Hochschild describes their worldview as one in which they’ve played by the rules, worked hard, and waited patiently, only to see others “cut in line.” The result is a potent mix of pride and resentment.
Add to this a fractured media environment. With traditional journalism in decline, many turn to partisan outlets like Fox News. Without broad exposure to differing viewpoints or tools for critical thinking, disinformation thrives. Trump’s messaging, rooted in grievance and emotional appeal, finds fertile ground.
The End of Globalization
Underlying it all is a deeper shift: the decline of the globalization era. From the 1990s to the 2010s, globalization promised prosperity through free trade, open borders, and technological exchange. But while it enriched some, it devastated others—offshoring jobs, hollowing out industries, and widening inequality. Entire regions were left behind.
By 2024, Americans knew exactly who Trump was, a vindictive, self-serving felon with a well-known policy playbook: mass deportations, trade wars, tax cuts, and environmental withdrawal. And yet, they voted him in again. Why? Because he spoke to the disillusionment globalization left in its wake. People feel angry about immigration, fearful for their jobs, distrustful of government, and helpless in the face of climate change. These raw emotions are not just political; they are personal, embodied, and deeply human.
A New Lens
Understanding Trump’s enduring appeal requires more than disbelief or outrage. It demands empathy, science, and attention to the long arc of history. Beneath the bluster lies something elemental: fear of loss, longing for order, and the ache of being left behind. It’s not just about Trump, it’s about the world that made him possible.
