From fireflies to mammals, evolution may have tuned communication to the rhythm of neurons.John Ternus has entered one of the most visible positions in global business without trying to turn his first days into a personal media event. The new CEO arrived with a remarkably discreet public profile, a newly opened social presence and decades of work completed mostly behind Apple’s products.
His X account, @johnternus, appeared publicly on September 1, the day he officially succeeded Tim Cook. Its biography contained only the company logo and his new title. The first post was even shorter: “hello.”
The simplicity felt consistent with an executive who has spent most of his career explaining materials, engineering decisions and manufacturing improvements rather than building a public personality. It also created a sharp contrast with the scale of the position he now occupies.
Ternus can remain personally reserved, but the CEO role will repeatedly place him before customers, employees, investors, governments and developers. His first social post may have been quiet. The responsibilities arriving behind it are anything but.
Ternus did not maintain a prominent public social account during his years leading hardware engineering. Most customers encountered him through carefully produced product presentations, occasional interviews or appearances focused on a particular device.
Even within those settings, his style remained technical and controlled. He usually spoke about engineering choices, durability, materials, performance and the work required to turn a design into a product that could be manufactured at enormous scale.
His new X account does not immediately change that character. Opening a channel is different from revealing a private life or becoming a daily commentator. The minimal introduction suggests a place for official communication rather than an invitation into every passing thought.
That would follow an established pattern for senior leadership. Tim Cook used his public account to acknowledge product launches, employees, social causes, environmental initiatives, community visits and major events. His posts rarely became extended personal debates.
Ternus may adopt a similar rhythm, although the account is too new to define its purpose. One word and a short biography cannot tell us how frequently he will post, which subjects he will address or whether he will write directly during moments of controversy.
The restrained opening still served one practical purpose. It established an authenticated public identity before unofficial profiles, impersonators and parody accounts could occupy the space around a newly appointed CEO.
The limited public profile should not be mistaken for limited influence inside the company.
Ternus joined the product design team in 2001 and became a vice president of hardware engineering in 2013. He entered the executive team as senior vice president in 2021, eventually overseeing engineering work across iPhone, iPad, Mac, AirPods and Apple Watch.
His official biography credits him with an instrumental role in the introduction of iPad and AirPods, along with work across multiple generations of the company’s largest product lines. It also connects his leadership to improvements in reliability, durability, materials, repairability and environmental performance.
This background gives Ternus a different starting point from a CEO recruited principally through finance, sales, software or public policy. He arrives from the part of the organization responsible for making difficult designs function consistently outside a laboratory.
Hardware engineering at this scale reaches far beyond choosing a processor or shaping an enclosure. It requires coordinating displays, batteries, cameras, radios, thermal systems, structural materials, manufacturing equipment, repair procedures and supplier capacity. A small change can affect production across millions of units.
That experience may explain part of his measured communication style. Engineering organizations reward details that survive testing. Public attention often rewards immediate confidence. Ternus has spent his career in an environment where confidence eventually meets a drop test, production line or repair bench.
His public appearances have often carried the same discipline. He tends to explain what a product team accomplished without placing himself at the center of the accomplishment.
Leading hardware engineering allowed Ternus to speak after a product decision had passed through years of development. As CEO, he will also need to speak while difficult questions remain unresolved.
Investors will expect him to explain spending, growth and long-term priorities. Governments will want answers about manufacturing, competition, privacy and platform control. Employees will look for direction as artificial intelligence, robotics, home technology, augmented reality and satellite communications create new opportunities across the company.
Customers will judge him through products, but they will also hear his response when a launch disappoints, a service fails or a policy creates frustration.
This is where a discreet profile can become either an advantage or a limitation.
A CEO who does not comment constantly preserves the weight of the moments when he chooses to speak. Fewer posts also reduce the chance that a hurried reaction becomes the story instead of the company’s work.
Silence becomes harder to maintain when people expect reassurance. Product defects, security incidents, employee concerns and political disputes can create situations in which a carefully prepared statement feels too distant. Ternus will have to decide when restraint protects the company and when it begins to look like avoidance.
Cook will remain involved as executive chairman and is expected to assist with areas including engagement with policymakers. That arrangement gives Ternus continuity during the transition without removing the need to develop his own public authority.
The distinction between their roles will become more visible with time. Cook can offer experience and institutional relationships, but employees and customers need to recognize which priorities belong to the new CEO.
Ternus does not need to imitate Steve Jobs’ stage presence or Cook’s diplomatic style. A convincing public identity can grow from the expertise that brought him to the position.
The most natural version would be an engineering-minded CEO who explains trade-offs without turning every decision into a slogan. Product design is full of compromises involving battery life, weight, cost, durability, repairability and production capacity. Carefully explaining some of those decisions could make corporate communication more informative.
His 2024 commencement appearance at Penn Engineering offered a rare view outside a product presentation. Ternus returned to the university where he earned his mechanical engineering degree and addressed students as an experienced engineer rather than a celebrity executive.
That type of setting allows more personality to appear without requiring constant social posting. Longer interviews, engineering discussions, employee conversations and educational appearances may suit him better than trying to manufacture spontaneity several times a day.
A restrained profile could also reinforce collaboration. The products reaching customers are built by large teams, and Ternus has generally presented himself as a representative of that work. Maintaining that tone as CEO would keep attention on the organization rather than turning every announcement into a personal performance.
The difficulty will be preserving technical depth while discussing areas beyond hardware. Services, entertainment, artificial intelligence, software platforms and international policy cannot always be explained through materials and manufacturing. The CEO must connect them into one recognizable direction.
The opening “hello” gives Ternus room to decide how visible he wants to become.
Upcoming product events will offer an early test. A social account can distribute announcements and photographs, but the stage will reveal more: which subjects he chooses to introduce, how much technical detail he includes and whether he remains present throughout the presentation or delegates most of it to other executives.
Earnings calls will create a different test. Product videos are rehearsed around finished work; financial discussions require direct answers about demand, margins, investment and risks. His language in those conversations will begin shaping how investors understand the new administration.
Internal communication may prove equally influential even when the public sees only fragments. Employees will listen for signals about decision-making speed, tolerance for experimentation and the relationship between engineering ambition and commercial discipline.
The X account can support that work, but it cannot substitute for it. A polished stream of product announcements would tell customers what has shipped. Occasional direct messages during difficult moments would reveal more about how Ternus intends to lead.
For now, the empty space around his first post is part of the story. The next useful signal may not be how often John Ternus speaks, but which moment persuades this notably private engineer that the CEO should speak in his own voice.

A University of St. Andrews-led research team has proposed that the red wavelengths of flickering light emitted by early human ancestors’ campfires helped reprogram the human brain to boost social and verbal communication, leading to modern language and storytelling behaviors found only in humans.
The team, which included researchers from Dartmouth College, said the study builds on earlier theories linking fire and language to the extra hours it added to the day.
However, their findings suggest that the biological changes caused by fire use may have enabled complex language as much as fire-associated behavioral changes, accelerating the evolution of verbal communication away from the ape-like systems still used by modern apes toward more complex, “uniquely human” interactions.
Catherine Hobaiter, a Professor of the School of Psychology and Neuroscience at the University of St Andrews and the lead author of a paper detailing the team’s idea, said she has always been fascinated by the origins of language.
“What was the first word?” the professor asked. “The first story?”
Unfortunately, Professor Hobaiter noted, many questions about the origin of humanity’s complex and diverse forms of verbal communication remain unanswered.
Some earlier research has explored a possible link between the first spoken words and the advent of controlled fire use. However, the team notes that most studies have focused primarily on the extra hours of practical light added to the end of each day.
Curious whether other biological mechanisms also contributed to the evolution of language and complex storytelling behavior, Professor Hobaiter and colleagues examined the effects of sitting around a campfire to see whether the emitted light could reprogram the human brain.
First, the team noted that one potential catalyst emitted by firelight that could help reprogram the human brain for complex language is the color of the light wavelengths emitted by campfires. Specifically, Hobaiter and colleagues noted that campfire light emits almost no blue wavelengths but instead mostly in the visible red spectrum.
Many modern studies have focused on the potentially adverse effects of exposure to blue light wavelengths from modern technology on sleep patterns and overall health. Conversely, the paper’s authors described the red wavelengths emitted from fire as ‘uniquely suited’ for human socializing, “allowing an extension to the day without negatively impacting sleep.”
Another component of firelight the study authors suggest could have reprogrammed the human brain for speech is the way a campfire behaves. Unlike a modern, steady light source, the authors noted that firelight “flickers.”
Hobaiter and colleagues said that neurons in the human brain synchronize firing patterns with external flickering lights. For example, flickering lights in movies and TV shows often come with warnings against possible neurological effects on vulnerable viewers. The research team said this mechanism might also help synchronize the behavior of those seated around the campfire, resulting in a much deeper feeling of connection.
Finally, the researchers noted that firelight emits infrared wavelengths, which may have also contributed to helping firelight reprogram the human brain for complex verbal communication.
When discussing the potential impact of their proposal, study co-author Nathaniel Dominy, the Charles Hansen Professor of Anthropology at Dartmouth College, said many of the chemical properties have been well researched. However, Professor Dominy also notes that understanding the properties of light that capture our attention and focus, thereby instilling “harmony and cooperation,” has received far less attention.
“Measuring these features is an exciting part of this project,” the study author added.
Professor Hobaiter agreed, while also noting the conundrum scientists face when explaining why humans speak, when “decades of research with other species has shown us that you don’t need language to learn from each other, to organize where and when to forage, to learn cultural knowledge about tools and songs, to co-ordinate hunting, or navigate social politics.”
“While other species share all these skills, there is a fundamental puzzle: we struggle to find evidence of key differences between human and ape communication,” Professor Hobaiter explained. “And yet, we are surrounded by evidence of human distinctiveness. For all their incredible, rich communication and cultures, no other ape is inventing algebra, writing King Lear, or heading out into interstellar space.”
“So, it’s especially exciting to be able to generate testable predictions, to be able to ask if, at the end of the day, we are the storytelling ape,” the professor added.
The paper “Firelight and the Origins of Spoken Language” was published in Proceedings of the Royal Society.

Growing news coverage of UFOs is influencing people’s views about extraterrestrial life, particularly among younger Americans, according to a new survey.
According to the survey’s findings, more than a third of respondents—and particularly younger adults—say recent reporting on unexplained aerial phenomena has strengthened their belief that aliens exist.
Connecting data from over 2,000 Americans, the survey found that 37% say recent news coverage about UFOs has increased their belief in extraterrestrial life (ET). Meanwhile, 54% say their views have not changed, and just 10% report that the coverage has made them less likely to believe in ET. The survey was conducted by Talker Research between July 1 and July 6, 2026.
According to the survey’s findings, more than half of Gen Z respondents—54%—said recent UAP news has increased their belief in ET. That figure drops to 45% among millennials, 36% among Gen X, and 23% among baby boomers.
These results arrive amid an increasingly mainstream conversation surrounding government hearings, military UAP reports, whistleblowers, broadcast and online news coverage, and podcasts. Such exposure may be helping shape how Gen Z views what is possible and whether intelligent life exists elsewhere in the cosmos.
Looking at the results through a gender lens, 34% of men say UFO news coverage has made them more likely to accept that we are not alone in the universe, compared with 33% of women.
Historically, widely publicized UFO reports have helped shape the language and imagery Western society uses to describe unexplained aerial phenomena. One famous example occurred in 1947, when pilot and businessman Kenneth Arnold reported seeing unusual objects flying near Mount Rainier, an incident that received widespread media coverage.
The idea behind such a cultural feedback loop is relatively straightforward: someone sees something outside their normal understanding of reality and reports it. Media and entertainment then pick up the concept and expand upon it, creating their own interpretations of what extraterrestrial beings or UFOs might look like. Audiences absorb those representations, which may subsequently influence how some people perceive, remember, or describe their own unusual experiences. Those accounts can then return to popular culture, potentially reinforcing the cycle.
This doesn’t necessarily mean that what a person saw wasn’t anomalous. Instead, it suggests that media and entertainment may influence how people interpret or describe what they experience.
A 2025 paper in Evolutionary Human Sciences deconstructs a “two-way feedback loop between behavior and beliefs.” The framework suggests that existing beliefs influence behavior; people then observe that behavior, and the observed behavior influences what people believe others think/do. Finally, those beliefs influence subsequent behavior.
The new survey also considered the potential influence of popular culture. More than half of respondents (54%) believed alien movies and television make Americans more likely to believe in the existence of intelligent extraterrestrial life; 27% saw no connection between entertainment and belief, while 8% believed such programming actually makes people less likely to believe.
An additional consideration when reading this survey is whether UFOs themselves should be characterized as a belief system. The subject is also an area of study examined by researchers from a range of disciplines, including psychology, philosophy, physics, anthropology, neuroscience, and others.
Many academics would argue that categorizing UFOs solely as a belief system risks pigeonholing the subject as a form of religion rather than recognizing it as an area of study. A belief system, by contrast, is a framework of ideas through which people interpret reality according to a particular set of assumptions or principles.
Jeffrey Kripal, J. Newton Rayzor Professor of Religion at Rice University’s Department of Religion, addressed related questions in his March 2026 keynote, “Mind-Manifesting Shock: Comparing Psychedelic and Abduction Experiences, Religion and Psychedelics: Critical Cross-Cultural, Cross-Disciplinary Approaches,” at the Center for the Study of Religion at Ohio State University.
“We are often ‘believing backwards,’ taking comfort in someone else’s altered states, or in the present ‘explanations’ of this or that neuroscience or physics,” Kripal said at the time.
In other words, when people experience something anomalous and ask why it happened or what the experience might mean, they may immediately reach backward for an existing framework through which to interpret it.
In an email to The Debrief, Kripal adds, “I think the existing frameworks of religion and science ‘explain’ to people what happens, though they do not.”
The Debrief also reached out to Matthew Halsted, Associate Professor of Biblical Studies and Executive Team/Registrar at Eternity College, and asked how he would classify UAP—as an area of belief or a subject of study—and why.
“When it comes to ‘UAP,’ we have to see it as a two-sided coin,” Halsted told The Debrief. “On one side, we have the phenomenon itself (the actual sighting of the thing in the sky); on the other side of the coin, we have the public narrative (how we as people, and our respective governments, talk about reported sightings).”
Halsted adds, “The UAP topic (the ‘coin’) creates a lot of questions for the public, which inevitably gives rise to some sort of belief system. Some walk away believing it’s all nonsense, while others believe there’s something real about this whole thing.”
Halsted’s view, therefore, appears more nuanced than simply classifying UAP as a belief system: the topic can generate belief systems and competing interpretations around reported phenomena, but the subject itself extends beyond a simple question of belief versus nonbelief.
When asked how they would react if extraterrestrial life were definitively confirmed, 38% of Americans said their first response would be curiosity, more than twice the 17% who said they would be fearful. Men were also more likely than women to say they would be excited by such a discovery, at 20% compared with 11%.
Perhaps more strikingly, 60% of participants believed that governments know more about UFOs than they have disclosed to date.
The bigger question is whether participants believe society is prepared to accept confirmation that extraterrestrial life exists. Forty-five percent believe society would be prepared if governments confirmed the existence of alien life, while 55% say society would not be adequately prepared to comprehend the implications.
“It’s clear that the public—across age groups—is clamoring for greater UAP transparency,” said Christopher Mellon, a former Deputy Assistant Secretary of Defense for Intelligence and current Chairman of the Board with the Disclosure Foundation, which also conducted a recent survey on the subject in June. According to Mellon, the survey found that “more than 84% of Americans want greater transparency, regardless of whether they consider themselves believers, skeptics, or unsure. And a recent Talker Research poll found that 54% of Gen Z say recent news stories have increased their belief in UAP.”
“We believe the best way to meet that demand is with more, and better, information,” Mellon told The Debrief. “That means giving the public access to higher-quality imagery, radar data, and other evidence that can help people assess the phenomenon for themselves. The Disclosure Foundation is working closely with Congress and the Administration on a near-daily basis to improve both the quality and quantity of UAP data being released to the public. If better data does exist, continued secrecy only fuels more speculation and questions.”
The modern public discussion surrounding UAP changed significantly following reporting in 2017 that appeared in The New York Times and other outlets, which revealed the existence of a Pentagon program that had investigated what the U.S. military now calls unidentified anomalous phenomena. Since that time, former officials—including Mellon—have pushed for action regarding the national security implications of unidentified objects operating in restricted airspace.
The survey’s findings are compelling, but they leave another important factor largely unaddressed: not simply how information is perceived, but how easily misinformation and disinformation can proliferate in an era of online news, podcasts with inconsistent fact-checking standards, questionable or compromised sources, and clickbait headlines engineered to capture attention.
The issue, then, is not merely what a generation believes, but how people decide what is real and what is not. Within today’s fragmented information environment, audiences increasingly face the difficult task of distinguishing credible evidence from speculation, honest mistakes from misinformation, and legitimate reporting from deliberate deception.
None of this means that the broader UFO enigma can simply be dismissed. Rather, it underscores an additional challenge surrounding the subject: misleading or demonstrably false claims can now reach large audiences very quickly.
Addressing that problem will require better media literacy, stronger sourcing and fact-checking standards, and greater attention to the often-blurred distinction between evidence and interpretation. Ultimately, younger generations coming of age amid an unprecedented volume of digital information will have to navigate those distinctions for themselves. How successfully they learn to do so may have consequences extending far beyond what they believe about UFOs—shaping how they understand science, institutions, current events, and reality itself.
This is why it’s critically important that we understand UAP as accurately as possible. Whether information is being communicated between family members, friends, researchers, journalists, or policymakers, distinguishing established facts from interpretations and unverified claims gives people a better foundation for understanding the world around them and making informed decisions.
This survey suggests that UFOs are no longer confined to a subculture or counterculture; the topic has entered the mainstream. The question now is what that shift will mean for the future.
