A mounting body of research is making it harder for companies to justify what most of them still do -- push experienced workers out the door just as they're hitting their professional peak. A 2025 study published in the journal Intelligence analyzed 16 cognitive, emotional and personality dimensions and found that while processing speed declines after early adulthood, other capabilities -- including the ability to avoid distractions and accumulated knowledge -- continue to improve, putting peak overall functioning between ages 55 and 60. AARP and OECD data back this up at the firm level: a 10-percentage-point increase in workers above 50 correlates with roughly 1.1% higher productivity. A 2022 Boston Consulting Group study found cross-generational teams outperform homogeneous ones. UK retailer B&Q staffed a store largely with older workers in 1989 and saw profits rise 18%. BMW implemented 70 ergonomic changes at a German plant in 2007 and recorded a 7% productivity gain. Yet an Urban Institute analysis of U.S. data from 1992 to 2016 found more than half of workers above 50 were pushed out of long-held jobs before they chose to retire.

Has the rise of hyper-addictive digital technologies really shattered our attention spans and driven books out of our culture? Maybe not, argues social psychologist Adam Mastroianni (author of the Substack Experimental History): As a psychologist, I used to study claims like these for a living, so I know that the mind is primed to believe narratives of decline. We have a much lower standard of evidence for "bad thing go up" than we do for "bad thing go down." Unsurprisingly, then, stories about the end of reading tend to leave out some inconvenient data points. For example, book sales were higher in 2025 than they were in 2019, and only a bit below their high point in the pandemic. Independent bookstores are booming, not busting; at least 422 new indie shops opened in the United States last year alone. Even Barnes & Noble is cool again. The actual data on reading, meanwhile, isn't as apocalyptic as the headlines imply. Gallup surveys suggest that some mega-readers (11+ books per year) have become moderate readers (1-5 books per year), but they don't find any other major trends over the past three decades. Other surveys document similarly moderate declines. For instance, data from the National Endowment for the Arts finds a slight decrease in the percentage of U.S. adults who read any book in 2022 (49%) compared to 2012 (55%). And the American Time Use Survey shows a dip in reading time from 2003 to 2023. Ultimately, the plausibility of the "death of reading" thesis depends on two judgment calls. First, do these effects strike you as big or small...? The second judgment call: Do you expect these trends to continue, plateau, or even reverse...? There are signs that the digital invasion of our attention is beginning to stall. We seem to have passed peak social media — time spent on the apps has started to slide. App developers are finding it harder and harder to squeeze more attention out of our eyeballs, and it turns out that having your eyeballs squeezed hurts, so people aren't sticking around for it... Fact #2: Reading has already survived several major incursions, which suggests it's more appealing than we thought. Radio, TV, dial-up, Wi-Fi, TikTok — none of it has been enough to snuff out the human desire to point our pupils at words on paper... It is remarkable, even miraculous, that people who possess the most addictive devices ever invented will occasionally choose to turn those devices off and pick up a book instead. The author mocks the "death of reading" hypothesis for implying that all the world's avid readers "were just filling time with great works of literature until TikTok came along."

An anonymous reader shares a report: Republicans' tax cuts shaved billions off Amazon's tax bill, new government filings show. The company says it ran a $1.2 billion tax bill last year, down from $9 billion the previous year, and even as its profits jumped by 45% to nearly $90 billion. That's largely because of the generous new depreciation breaks GOP lawmakers included in their One Big Beautiful Bill, something that's particularly important to Amazon which -- in addition to maintaining a vast infrastructure for its ubiquitous delivery business -- has been spending billions to build out artificial intelligence data centers. Also helping, though less important: The law's expanded breaks for businesses research and development expenses. The company has long been criticized by Democrats for paying little in tax, and it appeared to be bracing for criticism in the wake of the report to the Securities and Exchange Commission.

German newspaper Bild reported in January that some ski jumpers have been injecting their penises with hyaluronic acid ahead of the Milan Cortina Winter Olympics -- the theory being that temporarily enlarged genitalia would yield looser-fitting suits when measured by 3D scanners, and those looser suits could act like sails to produce longer jumps. A study published last October in the scientific journal Frontiers found that a 2cm suit change translated to an extra 5.8 metres in jump distance. No specific athletes have been accused. The World Anti-Doping Agency said Thursday it would investigate if presented with evidence, noting its powers extend to banning practices that violate the "spirit of sport." The claims arrive as ski jumping already faces scrutiny -- two Norwegian coaches and an equipment manager received 18-month bans in January for illegally manipulating suit stitching.

Kalshi, the largest U.S. prediction market, accused a small data startup called Juice Reel of "extortion" after a stock analyst used the company's transaction-level data to argue that prediction market users lose money faster than gamblers on traditional betting apps -- then walked the allegation back hours later. The equity research analyst Jordan Bender at Citizens found that the bottom quarter of prediction market users lost about 28 cents of every dollar wagered in their first three months, compared to roughly 11 cents per dollar on sites like FanDuel and DraftKings. Kalshi's head of communications told Bloomberg the report was "flat-out wrong" and called the data an extortion attempt. Juice Reel CEO Ricky Gold said Kalshi had actually pressured him to tell Bloomberg the data was inaccurate. Kalshi later issued an updated statement saying it continued to dispute the findings but "after further review, we don't believe the intention was extortion." The company did not provide any data to counter the analysis.

Microsoft has finally delivered on its promise to integrate Sysmon -- the long-standing system monitoring tool from its Sysinternals suite -- directly into Windows, a move that should make life considerably easier for enterprise administrators who have struggled with deploying and managing the utility across thousands of endpoints. The functionality landed this week in Windows Insider builds 26300.7733 (Dev channel) and 26220.7752 (Beta channel). Sysmon allows administrators to capture system events through custom configuration files, filter for specific activity, and pipe the data into standard Windows event logs for pickup by security tools and SIEM pipelines. Mark Russinovich, Microsoft technical fellow and Winternals co-founder, has previously noted the lack of official customer support for Sysmon in production environments -- a gap this integration addresses. The feature ships disabled by default and requires PowerShell to enable. Microsoft notes that any existing Sysmon installation must be uninstalled before activating the built-in version.

Pinterest has sacked two engineers for tracking which workers lost their jobs in a recent round of layoffs. BBC: The company recently announced job cuts, with chief executive Bill Ready stating in an email he was "doubling down on an AI-forward approach," according to an employee who posted some of the memo on LinkedIn. Pinterest told investors the move would impact about 15% of the workforce, or roughly 700 roles, without saying which teams or workers were affected. But then "two engineers wrote custom scripts improperly accessing confidential company information to identify the locations and names of all dismissed employees and then shared it more broadly," a company spokesperson told the BBC. "This was a clear violation of Pinterest policy and of their former colleagues' privacy," the spokesperson added. The script written by the Pinterest engineers was aimed at internal tools used at the company for employees to communicate, according to a person familiar with the firings who asked not to be identified. The person said the script created an alert for which employee names within a tool like the team communication platform Slack were being removed or deactivated, giving some insight into who at the company was impacted by the layoffs.

Walmart's market cap surpassed $1 trillion on Tuesday, putting the largest U.S. retail chain in an exclusive club dominated by tech groups. Bloomberg adds: The Bentonville, Arkansas-based chain -- a longtime favorite of bargain-hunting consumers -- has flexed its massive scale and supplier network to keep prices low and grab market share across the income spectrum. While Walmart has maintained its appeal to households looking for value, its online offerings are drawing new, wealthier shoppers seeking convenience.
