Study: ChatGPT may be eroding critical thinking skills
(NewsNation) — A new study led by researchers at MIT reveals that using OpenAI's ChatGPT could be negatively impacting the brain's critical thinking skills.
Researchers divided 54 students into three different groups and asked them to write essays using ChatGPT, Google's search engine and nothing at all. Using electroencephalograms (EEGs), they recorded each participant's brain activity and found that ChatGPT users had the lowest brain engagement and 'consistently underperformed at neural, linguistic, and behavioral levels.'

The study also revealed that over the course of the several months the study was conducted, the people who used ChatGPT put much less effort into the essays by just typing the prompt into the AI software and having it do all the work. ChatGPT users also retained less information from the essays that were written.
The effect was termed 'cognitive debt' by researchers, highlighting how constant reliance on AI systems may impair the cognitive processes underlying independent thinking.
The brain-only group showed the highest neural connectivity in areas of the brain responsible for language comprehension, creativity and memory. The group that used Google had moderate brain engagement throughout the course of the study.

Crypto IPO: 3 Things You Need To Know About The IPO Season
The Wall Street sign in the Financial District of Lower Manhattan in New York City. Circle's successful IPO has sent a signal. A strong one. The crypto world is heating up again, but this time, it's happening on Wall Street. Crypto companies are making a comeback after a long period of regulatory uncertainty. Circle, the stablecoin issuer, has initiated a global sensation in capital markets. Understandably so. Circle's recent debut on the New York Stock Exchange as CRCL was impressive, to say the least. CRCL's share price skyrocketed nearly 600% from its IPO price of $31 to a high of $215 during the day. With a market cap of $45 billion, Circle has quickly become the representative of a new trend, giving rise to a crypto IPO season. Was it a flashy debut? Yes, and for all good reasons. Circle's IPO, the biggest in recent history, marks a major milestone in the industry's journey toward mainstream acceptance. USDC, Circle's flagship stablecoin, is backed by over $32 billion in reserves and is already a core component of onchain finance, serving as a payment medium that dominates the whole crypto ecosystem. But there are three key things you need to know about this year's IPO season to understand this phenomenon. 1. It's Only The Beginning Of Crypto IPOs Just days after Circle's IPO, Gemini, the crypto exchange founded by Tyler and Cameron Winklevoss, confidentially filed paperwork for its own IPO in the U.S. At the same time, all eyes moved onto Kraken, which is reportedly preparing to go public sometime in early 2026. Another company making moves is BitGo, a regulated U.S. crypto custodian. Back in February, reports suggested it was aiming for an IPO as early as 2025. A few other names also stand out as potential IPO contenders: These companies span the entire spectrum, from custody and analytics to wallets and infrastructure. What they have in common is a fresh appetite for public capital and growing investor interest, especially institutional one. As one analyst put it, 'After watching Circle's stock take off, any crypto firm with a clear business model is now looking at the IPO route seriously.' 2. The IPO Process Although the range of companies participating in the IPO summer is wide, crypto exchanges are leading the charge in pursuing US stock market listings. Think Gemini, Kraken, Bullish Global, FalconX, and Bithumb. These types of businesses are particularly well-positioned for public listing due to their strong cash flows, large customer bases, and stable business models that appeal to traditional investors. There are different ways companies can go about executing public offerings. Traditional IPOs remain the gold standard, particularly for mature companies with strong compliance records and established business operations. However, this process is very complex and time-consuming, making it most suitable for larger platforms with proven business models and solid profitability. That's why for smaller cryptocurrency companies seeking a faster path to public markets, reverse mergers have become a popular alternative. Companies, such as TRON, have successfully leveraged this approach by acquiring existing public companies to quickly gain access to the stock market, bypassing the lengthy traditional IPO process. Meanwhile, some companies are opting for direct listings. This is shown by Kraken's approach, which achieved a $16.2 billion valuation. They were able to create market liquidity for their shares without the need to raise new capital, making it ideal for firms that don't necessarily require additional funding but instead want to provide exit opportunities for existing shareholders. 3. High Crypto IPO Expectations Circle has definitely set a high bar. Its stock soared, boosting confidence across the crypto sector. But Circle isn't your typical crypto company. Their stablecoin, USDC, is a go-to onchain payment solution. In addition, its business model—earning yield on reserve assets—is easy for traditional finance folks to understand. Retail and institutional demand are growing, and with a government no longer hostile, investors see 2025 as the year when crypto companies leverage the IPO playbook. The dramatic shift in institutional adoption is particularly compelling. As of January 2025, 86% of institutional investors reported having exposure to digital assets or planned to make digital asset allocations later in the year. Additionally, recent success stories have proven that crypto companies can achieve substantial valuations in public markets. Circle's roughly $1.1 billion public listing formed the largest crypto IPO in recent history, sparking high expectations among industry experts that more digital asset companies will soon follow suit. However, only time will tell if this crypto IPO summer turns into an IPO supercycle, but Coinbase being the best performing S&P500 stock in June is definitely a promising sign.

‘Huge' BlackRock Crypto Bombshell Suddenly Hurtling Toward Bitcoin At Key Price ‘Turning Point'
Bitcoin has bounced back in recent weeks, surging as serious U.S. dollar collapse fears drive billionaire interest in bitcoin. Front-run Donald Trump, the White House and Wall Street by subscribing now to Forbes' CryptoAsset & Blockchain Advisor where you can "uncover blockchain blockbusters poised for 1,000% plus gains!" The bitcoin price has soared toward its all-time high of $112,000 per bitcoin, with traders betting a looming Federal Reserve flip will turbo-charge the crypto market. Now, as U.S. president Donald Trump issues a surprise crypto prediction, bitcoin and crypto are braced for a 'huge' BlackRock crypto market bombshell that has suddenly appeared on the 'horizon.' Sign up now for the free CryptoCodex—A daily five-minute newsletter for traders, investors and the crypto-curious that will get you up to date and keep you ahead of the bitcoin and crypto market bull run BlackRock chief executive Larry Fink has become one of the most bullish bitcoin price voices on Wall ... More Street in recent years. In-kind redemptions for the bitcoin and crypto exchange-traded funds (ETFs) that have taken Wall Street by storm over the last 18 months could be coming soon, according to U.S. Securities and Exchange Commission (SEC) commissioner Hester Peirce. 'I can't prejudge, but we hear that there's a lot of interest,' Peirce, who heads up the SEC's crypto task force, said on stage at a Bitcoin Policy Institute event, adding that in kind bitcoin and crypto ETFs are now 'on the horizon.' In-kind redemptions allow investors to exchange ETF shares directly for the underlying asset rather than receiving cash, which is currently the case for the spot bitcoin and crypto ETFs approved by the SEC in early 2024—a change described as 'huge' by Bloomberg Intelligence ETF analyst Eric Balchunas. In-kind redemptions for bitcoin and crypto funds would make it cheaper and quicker for traders to buy and sell ETF shares, potentially making them more attractive to institutional investors on Wall Street. Earlier this year, BlackRock, which has dominated the spot bitcoin ETF market with its $75 billion IBIT fund, asked the SEC to permit in-kind creations and redemptions for bitcoin ETFs, instead of having to use cash, with the likes of Fidelity and other smaller bitcoin and crypto ETF providers following suit. "Those (forms) are going through the process now," Peirce said. Sign up now for CryptoCodex—A free, daily newsletter for the crypto-curious The bitcoin price has rocketed to an all-time high this year, helped by BlackRock's massive $75 ... More billion bitcoin exchange-traded fund (ETF). BlackRock, which manages after around $10 trillion worth of assets for investors, spearheaded Wall Street's campaign to bring a long-awaited spot bitcoin ETF to market in 2023, with a fleet of funds debuting in January 2024 that now hold 1.4 million bitcoin worth $152 billion. BlackRock's fund alone holds around 3% of the 21 million bitcoin that will ever exist, worth almost $75 billion at the current bitcoin price, which some have warned could be giving BlackRock outsized control over the network. Meanwhile, the combined bitcoin price and crypto market is on the verge of a 'turning point' as it hits $3.4 trillion, according to one analyst. 'The $3.4 trillion to 3.55 trillion range is a turning point, which has activated sellers and prevented the market from consolidating higher,' Alex Kuptsikevich, FxPro chief market analyst, said in emailed comments. 'Since the end of Wednesday, bitcoin has been testing the $108,000 mark, but it will sell off when it touches this level. Over the past couple of days, we have seen a smooth but steady intraday uptrend, accompanied by heavy buying from medium—and long-term investors. We see this as a sign of buying by professional market participants and link it to strengthening stocks, which increases the likelihood of reaching $110,000 or even $112,000 as early as this week.'

Protect Yourself From Sketchy Calls: Unknown Caller vs. No Caller ID
Like most of us, you're probably getting a lot of unsolicited calls that show up as either No Caller ID or Unknown Caller on your iPhone. Reflexively answering either one could lead to a scam -- or perhaps a call you've been waiting for. What are the differences between these two anonymous labels? Here's what to know about each type of call and how to keep yourself safe from potential scams. No Caller ID vs. Unknown Caller A call labeled "No Caller ID" means the caller has blocked their number from appearing on your screen. In other words, they want to keep their identity under wraps. This can be a privacy measure, but it's also a tool used by scammers -- if you can't quickly verify who the caller is based on their number, it can be easier to fall for their trap. "Unknown Caller," on the other hand, is the message that appears when your phone service provider doesn't recognize who's calling. This can come down to several factors, including network or technical issues, or receiving calls from foreign numbers. Oftentimes, these callers aren't intentionally trying to hide their identity, but it's still a good idea to be cautious. Scammers can also use this method to hide their identity by using a phone that isn't registered with the phone company, for instance. What to do if you get anonymous calls You should always proceed with caution if you can't identify a caller. This is especially important if someone rings you and "No Caller ID" appears on the screen, as they have intentionally kept their number hidden. But an Unknown Caller is also something to be wary of, since it becomes harder to truly identify who's at the other end of the line. Letting the call go to voicemail is often a good idea. Answering a call signals to scammers that your number is active, which could lead to more similar calls in the future. The Live Voicemail feature is particularly helpful for these situations because it allows you to pick up the call if the voicemail transcript indicates it's someone you want to speak with. Silence unknown callers on your iPhone You can even go a step further and silence unknown callers on your iPhone. That way, those mystery callers won't disturb you, and they can just leave a voicemail for you to check later. In your iPhone, go to Settings, then tap Apps followed by Phone and go to Silence Unknown Callers. Hit the toggle to turn it on. Watch this: Why You're Getting So Many Spam Calls 08:33 Use apps to block unidentified calls Though there isn't a way to block these anonymous calls within your iPhone's settings, your wireless carrier may offer apps to help with this. AT&T ActiveArmor, for instance, has a free version that blocks spam and fraud calls, and also lets you block all unknown callers. The advanced version, which costs $4 a month, includes tools like reverse number lookup and caller ID for unknown numbers. ActiveArmor is available for iOS and Android. Verizon's Call Filter app also offers spam detection, a spam filter and the option to report numbers, all for free. For an additional $4 a month, you'll also get caller ID, spam lookup, a personal block list and a spam risk meter. Call Filter is automatically enabled for Android users on a postpaid plan, and is available in the App Store for iPhone. T-Mobile's Scam Shield has a free option that includes full caller ID, scam reporting and scam blocking. There's also a premium option for $4 a month per line, which offers reverse phone number lookup and voicemail transcriptions that are automatically texted to you. You can download the Scam Shield app in the App Store or Google Play. Be sure to check with other wireless carriers to see if they offer something similar. Some wireless carrier plans may include access to the premium features as well. For more third-party apps to help limit robocalls and general tips, check out our guide on stopping spam calls.
