Are You Getting Dumber Using ChatGPT? What MIT’s Brain Study Reveals

Published

on

In the age of artificial intelligence, ChatGPT has become a go-to tool for students, professionals, and lifelong learners seeking quick answers, summaries, and even full essays. But is this convenience hurting our brains?

Researchers at the MIT Media Lab recently published a groundbreaking study, “Your Brain on ChatGPT,” that sheds alarming light on how reliance on AI tools like ChatGPT may be diminishing our critical thinking abilities and changing our neural activity in concerning ways.

The Study Setup: Three Groups, One Question

The researchers divided participants into three groups to write essays based on SAT-style prompts: one group used ChatGPT (the AI group), another used traditional search engines like Google (the search group), and a third wrote entirely unaided (the brain-only group).

Using EEG measurements to monitor brain activity, the team observed clear differences across groups during the essay-writing process. The unaided brain-only group showed the highest levels of brain engagement, particularly in regions associated with creativity, memory, and complex thinking. The search group also displayed active brain function as participants investigated and organized information themselves.

In stark contrast, the ChatGPT group demonstrated significantly lower brain activity, weaker neural connectivity, and reduced engagement. These participants often relied on ChatGPT to generate most of the essay content, leading to more generic work that lacked originality and personal insight.

Cognitive Offloading and the Illusion of Learning

What’s happening is a phenomenon known as cognitive offloading—when mental effort is passed onto an external tool. ChatGPT allows users to bypass the hard but necessary mental work of processing, connecting, and organizing information. Instead, users receive AI-generated answers that feel easier to understand but don’t deepen memory or expertise.

The study found that even after ceasing ChatGPT use, participants still exhibited diminished brain engagement compared to other groups, suggesting a residual negative effect that lingers beyond immediate AI usage.

Simply put, the more people rely on ChatGPT to deliver ready-made answers, the harder it becomes to develop the critical thinking skills necessary for original thought, problem solving, and long-term memory retention.

Why This Matters: The Future of Learning and Work

This research flies in the face of the popular notion that AI will automatically make us smarter or more efficient. Instead, it warns that over-dependence on AI might actually make learners “dumber” over time, undermining the very skills we most need in complex, rapidly changing environments.

For employers and educators, this raises a red flag. Artificial intelligence is not a magic bullet that replaces the need for deep expertise. Instead, it raises the bar for what true competence requires—because AI can easily generate average, generic content, human users must develop higher levels of expertise to add unique value.

How to Use AI Without Sacrificing Your Brain

The good news is that AI doesn’t have to sabotage learning. When used as an assistant—not a replacement—ChatGPT can save time on tedious tasks like finding resources or providing high-level overviews. The key lies in maintaining mental effort through:

  • Actively engaging with the information, interrogating AI-generated content for gaps, biases, or errors
  • Deliberately challenging yourself to connect ideas and build mental frameworks (schemas)
  • Using AI to supplement, not supplant deeper study, including reading primary sources, thinking critically, and solving problems independently

This approach helps preserve and even enhance brain function by keeping the critical thinking muscles active.

The Final Word

The MIT study’s findings are a wake-up call in an AI-saturated world: convenience brought by tools like ChatGPT may come at the cost of cognitive health and intellectual growth if misused. While AI can be a powerful learning assistant, it cannot replace the mental effort and deep engagement essential to real understanding.

If the goal is to become more knowledgeable, skilled, and employable—not just to get quick answers—the challenge is to leverage AI thoughtfully and resist the temptation to offload all the brainwork. Otherwise, the risk is that after a year of ChatGPT use, you might actually be less sharp than when you started.

The choice lies with the user: Will AI be used as a tool to boost real learning, or will it become a crutch that weakens the mind? The future depends on how this question is answered.

Google Accused Of Favoring White, Asian Staff As It Reaches $28 Million Deal That Excludes Black Workers

Published

on

Google has tentatively agreed to a $28 million settlement in a California class‑action lawsuit alleging that white and Asian employees were routinely paid more and placed on faster career tracks than colleagues from other racial and ethnic backgrounds.

How The Discrimination Claims Emerged

The lawsuit was brought by former Google employee Ana Cantu, who identifies as Mexican and racially Indigenous and worked in people operations and cloud departments for about seven years. Cantu alleges that despite strong performance, she remained stuck at the same level while white and Asian colleagues doing similar work received higher pay, higher “levels,” and more frequent promotions.

Cantu’s complaint claims that Latino, Indigenous, Native American, Native Hawaiian, Pacific Islander, and Alaska Native employees were systematically underpaid compared with white and Asian coworkers performing substantially similar roles. The suit also says employees who raised concerns about pay and leveling saw raises and promotions withheld, reinforcing what plaintiffs describe as a two‑tiered system inside the company.

Why Black Employees Were Left Out

Cantu’s legal team ultimately agreed to narrow the class to employees whose race and ethnicity were “most closely aligned” with hers, a condition that cleared the path to the current settlement.

The judge noted that Black employees were explicitly excluded from the settlement class after negotiations, meaning they will not share in the $28 million payout even though they were named in earlier versions of the case. Separate litigation on behalf of Black Google employees alleging racial bias in pay and promotions remains pending, leaving their claims to be resolved in a different forum.

What The Settlement Provides

Of the $28 million total, about $20.4 million is expected to be distributed to eligible class members after legal fees and penalties are deducted. Eligible workers include those in California who self‑identified as Hispanic, Latinx, Indigenous, Native American, American Indian, Native Hawaiian, Pacific Islander, and/or Alaska Native during the covered period.

Beyond cash payments, Google has also agreed to take steps aimed at addressing the alleged disparities, including reviewing pay and leveling practices for racial and ethnic gaps. The settlement still needs final court approval at a hearing scheduled for later this year, and affected employees will have a chance to opt out or object before any money is distributed.

H2: Google’s Response And The Broader Stakes

A Google spokesperson has said the company disputes the allegations but chose to settle in order to move forward, while reiterating its public commitment to fair pay, hiring, and advancement for all employees. The company has emphasized ongoing internal audits and equity initiatives, though plaintiffs argue those efforts did not prevent or correct the disparities outlined in the lawsuit.

For many observers, the exclusion of Black workers from the settlement highlights the legal and strategic complexities of class‑action discrimination cases, especially in large, diverse workplaces. The outcome of the remaining lawsuit brought on behalf of Black employees, alongside this $28 million deal, will help define how one of the world’s most powerful tech companies is held accountable for alleged racial inequities in pay and promotion.

3. Survivors’ Stories Highlight Patterns of Abuse and Silence

Interviews with alleged victims, former staff, and industry insiders describe patterns of control, fear, and emotional or physical harm that were long whispered about but rarely aired in this detail. Their stories underline how difficult it is to speak out against a powerful figure, teaching viewers why many survivors delay disclosure and why consistent patterns across multiple accounts matter.

4. 50 Cent’s Approach Shows Storytelling as a Tool for Accountability

As executive producer, 50 Cent uses his reputation and platform to push a project that leans into uncomfortable truths rather than protecting industry relationships. The series demonstrates how documentary storytelling can challenge established power structures, elevate marginalized voices, and pressure institutions to respond when traditional systems have failed.

5. The Cultural Backlash Reveals How Society Handles Celebrity Accountability

Reactions to the doc—ranging from people calling it necessary and brave to others dismissing it as a vendetta or smear campaign—expose how emotionally invested audiences can be in defending or condemning a famous figure. Watching that debate unfold helps viewers see how fandom, nostalgia, and bias influence who is believed, and why conversations about “cancel culture” often mask deeper questions about justice and who is considered too powerful to fall.

Luana Lopes Lara: How a 29‑Year‑Old Became the Youngest Self‑Made Woman Billionaire

Published

on


At just 29, Luana Lopes Lara has taken a title that usually belongs to pop stars and consumer‑app founders.

Multiple business outlets now recognize her as the world’s youngest self‑made woman billionaire, after her company Kalshi hit an 11 billion dollar valuation in a new funding round.

That round, a 1 billion dollar Series E led by Paradigm with Sequoia Capital, Andreessen Horowitz, CapitalG and others participating, instantly pushed both co‑founders into the three‑comma club. Estimates place Luana’s personal stake at roughly 12 percent of Kalshi, valuing her net worth at about 1.3 billion dollars—wealth tied directly to equity she helped create rather than inheritance.

Kalshi itself is a big part of why her ascent matters.

Founded in 2019, the New York–based company runs a federally regulated prediction‑market exchange where users trade yes‑or‑no contracts on real‑world events, from inflation reports to elections and sports outcomes.

As of late 2025, the platform has reached around 50 billion dollars in annualized trading volume, a thousand‑fold jump from roughly 300 million the year before, according to figures cited in TechCrunch and other financial press. That hyper‑growth convinced investors that event contracts are more than a niche curiosity, and it is this conviction—expressed in billions of dollars of new capital—that turned Luana’s share of Kalshi into a billion‑dollar fortune almost overnight.

Her path to that point is unusually demanding even by founder standards. Luana grew up in Brazil and trained at the Bolshoi Theater School’s Brazilian campus, where reports say she spent up to 13 hours a day in class and rehearsal, competing for places in a program that accepts fewer than 3 percent of applicants. After a stint dancing professionally in Austria, she pivoted into academics, enrolling at the Massachusetts Institute of Technology to study computer science and mathematics and later completing a master’s in engineering.

During summers she interned at major firms including Bridgewater Associates and Citadel, gaining a front‑row view of how global macro traders constantly bet on future events—but without a simple, regulated way for ordinary people to do the same.

That realization shaped Kalshi’s founding thesis and ultimately her billionaire status. Together with co‑founder Tarek Mansour, whom she met at MIT, Luana spent years persuading lawyers and U.S. regulators that a fully legal event‑trading exchange could exist under commodities law. Reports say more than 60 law firms turned them down before one agreed to help, and the company then spent roughly three years in licensing discussions with the Commodity Futures Trading Commission before gaining approval. The payoff is visible in 2025’s numbers: an 11‑billion‑dollar valuation, a 1‑billion‑dollar fresh capital injection, and a founder’s stake that makes Luana Lopes Lara not just a compelling story but a data point in how fast wealth can now be created at the intersection of finance, regulation, and software.
