The PISA 2025 results are out today. Some quick insights.
- The major story is very significant global decline. The last PISA study was in 2022, and saw big declines in reading and maths scores from 2018. Obviously the pandemic played a part.
- But this 2025 round has seen further falls even from the 2022 lows!
Things haven't gone back to normal post-pandemic - they've got worse.
Every generation thinks the generation below is less smart - but this time they might be right!

⚡️The chart is not telling me teenagers suddenly lost IQ.
It is telling me civilization has started consuming the cognitive substrate required to express intelligence.
The hidden variable is attention.
Reading, mathematics, and science all require the same underlying machinery: hold a problem in working memory, tolerate confusion, resist distraction, build a representation over time, then reason inside it.
Modern childhood increasingly trains the opposite loop:
stimulus → reaction → novelty → stimulus → reaction → novelty
Short video, notifications, algorithmic feeds, constant task-switching, reduced long-form reading, less boredom, less unstructured thought. The brain adapts to the environment it repeatedly inhabits.
So the frightening possibility is not “kids are genetically becoming stupider.”
It is:
we are taking perfectly capable brains and training them into cognitive shallowness during the years when attentional architecture is being built.
That would explain why reading gets hit especially hard. Reading is almost pure sustained internal simulation. Nothing moves. Nothing rewards you every three seconds. You must manufacture the world inside your own head.
And the pandemic looks more like an accelerant than the origin. The decline was already forming before it. COVID then removed structure, normalized screens further, damaged attendance, and widened learning gaps.
The next phase may be even stranger because AI removes another layer of cognitive friction.
Previously, a student who did not understand something had to wrestle with it.
Now the answer can appear immediately.
That is incredibly useful, but struggle itself is part of how cognition gets built.
So the deepest risk is not AI making people less intelligent.
It is humans progressively outsourcing the exact cognitive operations that used to develop intelligence in the first place.
The civilization-level pattern would be:
better tools → less cognitive friction → weaker native cognitive endurance → greater dependence on tools → even less friction
That is a reflexive loop.
And if it continues, you could get the strangest outcome imaginable:
the most intelligent civilization in history, surrounded by the most powerful cognitive machinery ever built, while the median human becomes less able to think without it.
That is what this chart makes me worry about.
Every three years the OECD, a club of mostly rich countries, releases the results of international school tests sat by 15-year-olds all across the world. Anyone who cares about the young of today should be alarmed at this year’s scores bit.ly/4zXPj6g

Those who pray are aware of their own limitations; they do not kill or threaten with death. Instead, death enslaves those who have turned their backs on the living God, turning themselves and their own power into a mute, blind and deaf idol (Ps 115:4–8), to which they sacrifice every value, demanding that the whole world bend its knee. Enough of the idolatry of self and money! Enough of the display of power! Enough of war! True strength is shown in serving life. #Peace

A message from a Kindergarten teacher:
After forty years in the classroom, my career ended with one small sentence from a six-year-old:
“My dad says people like you don’t matter anymore.”
No sneer. No malice. Just quiet honesty — the kind that cuts deeper because it’s innocent. He blinked, then added, “You don’t even have a TikTok.”
My name is Mrs. Clara Holt, and for four decades, I taught kindergarten in a small Denver suburb. Today, I stacked the last box on my desk and locked the door behind me.
When I started teaching in the early 1980s, it felt like a promise — a shared belief that what we did mattered. We weren’t rich, but we were valued. Parents brought warm cookies to parent nights. Kids gave you handmade cards with hearts that didn’t quite line up. Watching a child sound out their first sentence felt like magic.
But that world slowly slipped away. The job I once knew has been replaced by exhaustion, red tape, and a kind of loneliness I can’t quite describe.
My evenings used to be filled with construction paper, glitter, and glue sticks. Now they’re spent filling out digital reports to protect myself from angry emails or lawsuits. I’ve been yelled at by parents in front of twenty-five children — one filming me with his phone while I tried to calm another child mid-meltdown.
And the kids… they’ve changed too. Not by choice.
They arrive tired, anxious, overstimulated. Their tiny fingers know how to swipe a screen before they can hold a crayon. Some can’t make eye contact or wait in line. We’re expected to fix all of it — to patch the gaps, heal the trauma, teach the curriculum, and document every move — in six hours a day, with resources that barely fill a drawer.
The little reading corner I once built, full of soft beanbags and paper stars, was replaced by data charts and “learning metrics.” A young principal once told me, “Clara, maybe you’re too nurturing. The district wants measurable results.”
As if kindness were a weakness.
Still, I stayed. Because of the small, holy moments that no spreadsheet could measure —
a whisper of, “You remind me of my grandma.”
a shaky note that read, “I feel safe here.”
a quiet boy finally meeting my eyes and saying, “I read the whole page.”
Those tiny sparks were my reason to keep showing up.
But this last year broke something in me.
The aggression grew sharper. The laughter in the staff room turned to silence. The light went out of so many eyes. I watched brilliant teachers — my friends — vanish under the weight of burnout, their joy replaced by survival.
I felt myself fading too, like chalk on a board that’s been wiped one too many times.
So today, I began my goodbye. I pulled faded art off the walls and tucked thirty years of handmade cards into a single box. In the back of a drawer, I found a letter from a student from 1998:
“Thank you for loving me when I was hard to love.”
I sat on the floor and cried.
No party. No applause. Just a handshake from a young principal who called me “Ma’am” while checking his notifications.
I left my rocking chair behind, and my sticker box too. What I carried with me were the memories — the faces of hundreds of children who once trusted me enough to reach out their hands and learn. That can’t be uploaded. It can’t be measured. It can’t be replaced.
I miss when teachers were partners, not targets. When parents and educators worked side by side, not in opposition. When schools cared more about wonder than numbers.
So if you know a teacher — any teacher — thank them. Not with a mug or a gift card, but with your words. With your respect. With your understanding that behind every test score is a heart that cared enough to try.
Because in a world that often overlooks them, teachers are the ones who never forget our children.
Important piece of work by former bank analyst. @bankruncap . we should all gather behind a weekend buyer of the bank and work together to make @SVB_Financial strong again.

The gov’t has about 48 hours to fix a-soon-to-be-irreversible mistake. By allowing @SVB_Financial to fail without protecting all depositors, the world has woken up to what an uninsured deposit is — an unsecured illiquid claim on a failed bank. Absent @jpmorgan @citi or @BankofAmerica acquiring SVB before the open on Monday, a prospect I believe to be unlikely, or the gov’t guaranteeing all of SVB’s deposits, the giant sucking sound you will hear will be the withdrawal of substantially all uninsured deposits from all but the ‘systemically important banks’ (SIBs). These funds will be transferred to the SIBs, US Treasury (UST) money market funds and short-term UST. There is already pressure to transfer cash to short-term UST and UST money market accounts due to the substantially higher yields available on risk-free UST vs. bank deposits. These withdrawals will drain liquidity from community, regional and other banks and begin the destruction of these important institutions. The increased demand for short-term UST will drive short rates lower complicating the @federalreserve’s efforts to raise rates to slow the economy. Already thousands of the fastest growing, most innovative venture-backed companies in the U.S. will begin to fail to make payroll next week. Had the gov’t stepped in on Friday to guarantee SVB’s deposits (in exchange for penny warrants which would have wiped out the substantial majority of its equity value) this could have been avoided and SVB’s 40-year franchise value could have been preserved and transferred to a new owner in exchange for an equity injection. We would have been open to participating. This approach would have minimized the risk of any gov’t losses, and created the potential for substantial profits from the rescue. Instead, I think it is now unlikely any buyer will emerge to acquire the failed bank. The gov’t’s approach has guaranteed that more risk will be concentrated in the SIBs at the expense of other banks, which itself creates more systemic risk. For those who make the case that depositors be damned as it would create moral hazard to save them, consider the feasibility of a world where each depositor must do their own credit assessment of the bank they choose to bank with. I am a pretty sophisticated financial analyst and I find most banks to be a black box despite the 1,000s of pages of @SECGov filings available on each bank. SVB’s senior management made a basic mistake. They invested short-term deposits in longer-term, fixed-rate assets. Thereafter short-term rates went up and a bank run ensued. Senior management screwed up and they should lose their jobs. The @FDICgov and OCC also screwed up. It is their job to monitor our banking system for risk and SVB should have been high on their watch list with more than $200B of assets and $170B of deposits from business borrowers in effectively the same industry. The FDIC’s and OCC’s failure to do their jobs should not be allowed to cause the destruction of 1,000s of our nation’s highest potential and highest growth businesses (and the resulting losses of 10s of 1,000s of jobs for some of our most talented younger generation) while also permanently impairing our community and regional banks’ access to low-cost deposits. This administration is particularly opposed to concentrations of power. Ironically, its approach to SVB’s failure guarantees duopolistic banking risk concentration in a handful of SIBs. My back-of-the envelope review of SVB’s balance sheet suggests that even in a liquidation, depositors should eventually get back about 98% of their deposits, but eventually is too long when you have payroll to meet next week. So even without assigning any franchise value to SVB, the cost of a gov’t guarantee of SVB deposits would be minimal. On the other hand, the unintended consequences of the gov’t’s failure to guarantee SVB deposits are vast and profound and need to be considered and addressed before Monday. Otherwise, watch out below.
The amount of value that @SVB_Financial added to the technology and venture ecosystem cannot be overstated. On the other side of this, we in VC must all work together to return deposits to @SVB_Financial for the long term health of the technology sector.
The failure of @SVB_Financial could destroy an important long-term driver of the economy as VC-backed companies rely on SVB for loans and holding their operating cash. If private capital can’t provide a solution, a highly dilutive gov’t preferred bailout should be considered.

Progress isn’t always a straight line.
Today’s Supreme Court decision is wrong but Congress passing the Bipartisan Safer Communities Act is a modest but real step forward. And the fight will go on, thanks to the activists, survivors, and families who continue to demand action.
