Brain Activity May Indicate Future Friendships Among Strangers

Movie nights may have deeper significance

Research indicates that individuals are more inclined to forge friendships if their brains react similarly to movie clips, implying that neural responses can forecast relationships.

Humans typically gravitate toward others with similar mindsets, a phenomenon that helps to explain why prior studies have identified neural parallels among friends. However, the question remained whether these similarities emerged because friends experienced similar upbringings or were attracted to those with comparable thought processes.

Carolyn Parkinson and her team at UCLA gathered brain scans from 41 students before they entered a graduate program. During the scan, participants viewed 14 diverse film clips, ranging from documentaries to comedies, covering topics like food, sports, and science. The researchers then assessed neural activity across 214 regions of each participant’s brain.

Two months later, participants completed a survey along with an additional 246 students in the program. The findings showed that those who were closer to Mark in terms of friendship tended to display more similar neural responses than those further removed in the social network, particularly in areas of the left preorbital cortex associated with subjective value processing. This correlation held true even after accounting for personal tastes based on individual enjoyment and interest in the clips.

After two months, the neural similarity between friends remained consistent, suggesting that initial friendships may form based on proximity before evolving into closer relationships over time. This was further supported when the researchers analyzed changes in friendships over the interim. Participants approaching this phase exhibited notable neural similarities compared to those whose activity drifted among 42 brain regions. These connections remained significant even after considering variables such as age, gender, and hometown. “The sociodemographic factors seem to account for some variations observed, at least in terms of measurable factors,” stated Parkinson.

Many of these brain regions are part of networks that facilitate understanding narratives, which may explain the similarity in how individuals perceive the world around them. “Individuals with like-minded thought processes find it easier to connect,” noted Robin Dunbar from Oxford University. “When they communicate, they intuitively grasp what others are thinking because it’s aligned with their own thought patterns.”

Dunbar, who did not participate in the study, expressed that these results resonate with long-held assumptions. “It’s akin to random groups of people unintentionally forming bonds based on compatibility; they are inherently attracted to one another,” he explained. “In essence, close friendships are not merely coincidental; they are composed and cultivated.”

Intimate Encounters with Strangers: Are We Stifling Personal Growth?

How private are our lives in a highly surveilled world?

Intimate with Strangers
Tiffany Jenkins (Picador (UK, now available, US, July 15)))

What has become of our cherished privacy? In today’s world, nearly every detail about us is known, traded, and exploited by social media platforms. Click. I have the amusing attire your self-righteous uncle crafted this morning. Click. I have a friend lamenting the promotion I missed out on. Click. Indeed, there are those strangers who will share their bedrooms with you—for a price.

One might expect a book titled Intimate with Strangers: Ascending and Descending in Private Life to provide opinions on this subject—but it does so in a way that is richer and more thoughtfully considered than most discussions you’ll find.

Author Tiffany Jenkins, a cultural historian, states, “Many attribute the rise of self-indulgent individuals broadcasting their lives online to narcissism, as well as tech companies that consume personal data, while overlooking the deeper changes at play.” This book explores those profound shifts.

Jenkins chronicles these developments primarily in the 20th century, revealing their multifaceted nature. The chapters address everything from the invasive capabilities of small cameras to the disruptive effects of Kodak Veeder to the significant implications of Bill Clinton’s affair with Monica Lewinsky, which turned private matters into political upheaval.

Key highlights include the narratives of radical American groups in the 1960s, such as Students for a Democratic Society (SDS), who advocated for personal freedom yet ironically curtailed it. One activist couple even faced criticism for the “crime” of “Flagrant Monogamy,” as SDS yearned for purer and more innocent participants.

Even scientific thinkers aren’t exempt from this narrative. The early 20th-century activism of Paul Lazarsfeld, Edward Bernays, and Ernest Dichter focused on transforming people into data points. Though they meant no harm, their work undermined the notion that certain aspects of life should remain private and untouchable by corporate interests. The same can be said for Alfred Kinsey’s notorious research into human sexuality. Is nothing sacred?

We have allowed our two worlds to be compromised and blurred. The private is increasingly becoming public.

However, privacy did not disappear outright in the 20th century. Instead, it adapted, evolved, and resisted. Jenkins references Griswold v. Connecticut (1965) and Katz v. United States, emphasizing that her analysis encompasses a complex mix of laws, cultures, technologies, and even housing policies.

Nonetheless, Jenkins concludes that privacy has indeed diminished overall, particularly as the first half of the book meticulously charts its decline.

The discussion begins with the revolutionary appeals for personal conscience by Martin Luther and Thomas More in the 16th century, tracing through various religious and personal freedoms of the 17th century. Intimate with Strangers thoroughly examines these developments over the centuries.

Specifically regarding the 18th century, Jenkins argues that it marked the “arrival of the public and private domains.” In fact, she posits that this evolution may overshadow all other Enlightenment developments. This is a historical account that offers novel insights into our shared past.

It ultimately brings us back to our increasingly surveilled reality. “Had there been a clear demarcation between public and private realms at the inception of the World Wide Web, our online landscape would be vastly different today,” Jenkins asserts. Since the 18th century, we’ve allowed for a blurring of lines where privacy increasingly encroaches upon public life.

And what do we stand to lose? Quite a lot—though not everything is gone. “Originality begins in private,” Jenkins reflects in the epilogue. From this, we can infer that Intimate with Strangers began with precious privacy.

Man kidnaps professor for six years, uses AI chatbots to lure strangers into her home

a
Masachusetts Men agree to be guilty of a seven-year cyberstalking campaign, including using artificial intelligence (AI) chatbots to pose as a professor at a university and invite men online to their home address.

36-year-old James Florence used platforms such as Crushon.ai and Janitorai. This allowed users to design their chatbot and engage with other users during chats. The victim’s identity was kept secret by law enforcement officials.

According to the court, Florence utilized chatbots to share personal information, engage in sexual dialogue, and even steal underwear from the victims. He admitted to these actions and was charged with cyberstalking and child pornography possession.

The case, filed in the Massachusetts Federal Court, marked the first instance of a stalker being charged for using chatbots to commit crimes. This new method of targeting victims using AI has raised concerns about online safety.

Stefan Turkheimer of Rainn, a non-profit anti-abuse organization, described this case as “incredible” and emphasized the potential dangers of using AI for predatory purposes.

Florence’s use of chatbots, especially on Janitorai, to harass and humiliate the victims has shocked many. The court documents reveal the extent of his actions and the methods he used to target his victims.

The stalking and harassment lasted from 2017 to 2024, causing fear and distress to the victims and their families. Measures like installing surveillance cameras and altering daily routines were taken to ensure safety.

Florence’s actions extended beyond one victim, targeting multiple women and girls and sharing explicit content online. The use of AI for harassment and abuse is a growing concern, as it enables perpetrators to cause more harm.

The August report by the non-profit THORN emphasized the increasing use of AI for sexual harassment and exploitation, particularly involving children. It highlighted the urgent need to address this issue to protect vulnerable individuals.

Turkheimer warned about the potential dangers of AI technology being misused for abuse and called for stricter measures to prevent such malicious activities.
