President Donald Trump

Reviewed by Psychology Today Staff

President Donald J. Trump has completely upended traditional ideas about leadership and politics. In doing so, he has sparked tremendous psychological interest—from the traits of his character, to the emotions he elicits from the public, to the point at which mental health becomes a question of national security.

Psychological Interest in the Trump Presidency

President Trump has defiantly flipped the presidential script, making chaos and deliberate combativeness the new normal of White House operations, manifest in hostile briefings, high rates of staff turnover, and cultural exchanges that appear aimed at dividing the nation.

There is widespread debate about the degree to which Trump should be held directly or indirectly accountable for changes in civil discourse, with some citing his rhetoric and policies as a spur to hate crimes while others claim he has been unfairly demonized by the press.

Millions of people around the country and the globe have expressed bafflement at the nature of the personality at the center of it all, and many are alarmed by tactics and policies that appear not only erratic but often retrogressive and undermining of long-established democratic practices. Chief among them is a well-documented distortion of facts if not outright lies about everything from crowd size at the inauguration to discussions with foreign heads of state.

Throughout his term, a large segment of the population sought to quell their emotional reactivity to the chaos of the presidency and to rationally navigate the civic, legal, and ideological battles that play out daily, from Twitter to the federal courts.

Why has Trump changed ideas about leadership?

President Trump is like no other leader the nation has elected—bold, impulsive, turbulent, and divisive, with no political experience whatsoever. The traits most people value in a leader, research suggests, include intelligence, diligence, humility, honesty, and compassion. Fewer people prefer a “strongman” leadership style that encompasses selfishness, aggression, and manipulation (although this preference can diminish with time under such an administration). President Trump’s ability to frame himself as a populist, and succeed with authoritarian traits, has altered the template for leadership.

Why has President Trump changed ideas about truthfulness in public life?

The president’s falsehoods have fundamentally shifted society’s relationship with the truth. Past politicians have lied—but the Trump administration eroded the very notion that an objective truth exists. Instead, people seem to think that they’re entitled to their own truths. In addition to President Trump’s rhetoric of “fake news” and “alternative facts,” this shift is due to factors such as the creation and calcification of information silos and the evolution of the ability to believe things that can’t be seen.

President Trump’s Personality

Trump’s manifest grandiosity and disregard for facts, beginning with failure to accept clear evidence about the size of the crowd attending his inauguration, has put mental health professionals in the spotlight from Day One of his presidency.

Psychologists and commentators from all ideological camps early converged on a label of narcissistic personality disorder as the condition that “explains” Trump’s behavior. Among those making this assertion are more than 70,000 mental health professionals who signed a petition warning of Trump's potential dangerousness, despite longstanding professional injunctions against "diagnosing" public figures whom experts have not personally examined.

Americans remain divided as to how authoritarian or grandiose Trump may or may not be, as well as who has the authority to make clinical pronouncements or draw historical parallels.

At some as-yet-untested point, the clinical becomes the constitutional. The behavior of President Trump has sparked both legislative action and public discussion about whether and when to invoke the 25th Amendment to the Constitution, which calls for the orderly transfer of power when a president becomes temporarily or permanently incapacitated.

How do psychologists describe President Trump’s personality?

President Trump’s persona—outlandish, brash, and belligerent—compels attention and analysis, especially since he occupied tremendous power. For psychologists, his persona also invites interpretation because it maps so well onto many well-known psychological constructs. Some mental health professionals have publicly stated their view that Trump’s behavior aligns with the criteria for narcissistic personality disorder, antisocial personality disorder, and paranoid personality disorder, according to the DSM-5.

How do psychologists describe President Trump’s childhood?

In July 2020, President Trump’s niece and a clinical psychologist Mary Trump published the book Too Much and Never Enough: How My Family Created the World's Most Dangerous Man. Mary Trump writes that Trump’s mother was self-focused and absent, while his father lacked emotion and empathy. She argues that Trump had no role model for vulnerability, empathy, and reciprocity, and that displaying those traits was dangerous in the family’s household. President Trump tried to win his father’s approval throughout his life, which Mary Trump claims may inform the way he relates to certain world leaders today.

Psychological Terms That Characterize the Trump Presidency

Trump’s presidency has given rise to heated discussion about a range of psychological phenomena, well beyond the debate about his own personality. The term “gaslighting” refers to the manipulative attempt to make people question their own perceptions or memory, and it has often been invoked to describe Trump’s actions and statements, especially those about “fake news.”

The question of whether or not Trump’s style could accurately be characterized as authoritarian has sparked analysis of other world leaders, past and present. Whatever one’s position on Trump and his policies, a narrow area of agreement for most Americans is that the political climate has never been more corrosive and that it reflects, to a greater or lesser degree, Trump’s contrarian approach to leadership.

Why does gaslighting relate to the Trump presidency?

Gaslighting is a form of psychological manipulation that leads someone to doubt their experience of reality. Through consistent lying, misdirection, and contradiction, the gaslighter attempts to delegitimize the victim’s beliefs by confusing and destabilizing them. This can lead the victim to doubt their memory, perception, and sometimes even sanity.

President Trump has lied brazenly to the public throughout his term. Early examples include alleging that he had the largest inauguration day audience despite photographic evidence and dismissing Russian interference in the 2016 election as “fake news” despite a consensus from U.S. intelligence agencies. Trump’s frequent and bold lies, and his consistent effort to undermine people’s perception of truth, have led some to characterize Trump’s behavior as gaslighting.

Why do conspiracy theories relate to the Trump presidency?

Donald Trump’s political career was in part launched by promoting a conspiracy theory—that Barack Obama was not born in the United States. Throughout his term in office, Trump continued to embrace conspiracy theories, from claiming that Barack Obama had ordered FBI surveillance of the Trump campaign to refusing to disavow QAnon, the belief that a cabal of pedophiles is working to undermine the president. Conspiracy theories have generally been relegated to select corners of the Internet, but Trump has amplified them through the power of the presidency—lending dangerous claims a wider reach and greater credibility.

Anyone can fall down the rabbit hole of a conspiracy theory. Yet conspiracy thinking is correlated with certain personality traits, including low levels of trust, an increased need for closure, and feelings of powerlessness, low self-esteem, and paranoid thinking. Conspiracy theories also proliferate during times of crisis, which characterizes the last year of the Trump presidency, from the COVID-19 pandemic to the economic recession and racial reckoning.
