NEW thread: here’s the latest data on how vaccines are fighting Covid.

My India tweets earlier were grim, but these are more optimistic

Vaccines are working in the UK ✅, working in the US ✅, and contrary to alarmist reports, they’re working in Chile ✅ ft.com/content/d71729…
First, some more detail on the UK.

Cases, hospital admissions and deaths have fallen steeply among all groups (the 'restrictions effect'), but have fallen furthest and fastest among the older, most-vaccinated groups (vaccine effect).
(For anyone wondering why the UK deaths lines are getting bumpy, that’s a good thing:

The numbers are now so small — 20 Covid deaths per day — that random variation starts making things look noisy)
And it’s not just the very elderly who are benefiting. This chart (concept from @JamesWard73) shows that as UK vaccinations have progressed down through the age groups, so has the vaccine effect, with under-60s the latest to join the party.

It’s amazing how clear the pattern is!
Next, to France, where a third wave has hampered progress, but the same tell-tale signs of vaccinations are evident

Cases and hospitalisations rose in March, but climbed far slower among the most-vaccinated age groups. Deaths kept falling among the elderly despite 📈 among young
The resurgence of the pandemic in France — and many other countries in recent weeks — was fuelled by the arrival of the 'UK variant' B.1.1.7.

By March, it had become the dominant variant across all of Europe and is now spreading across North America.
B.1.1.7’s arrival in the US threatened one of the world’s most impressive vaccination rollouts, but as in France the data suggest the vaccines are prevailing 🙌

B.1.1.7 sent hospitalisations rising, but only among the [less vaccinated] young. Rates among elderly continue to drop
Sternest test for vaccines has come in Chile, where China’s Sinovac jab was rolled out during a third wave.

But again, the data suggest they’re working.

ICU occupancy has more than doubled among younger adults 📈, but is falling among age groups prioritised for vaccination 📉🙌
It’s the true that Sinovac is less effective than the likes of Pfizer, AstraZeneca and Moderna, especially after one dose (read @DubeRyan’s WSJ story here wsj.com/articles/first…), but after two doses, it delivers good efficacy and is keeping people out of ICU, saving lives.
So we now have clear, real-world data from many countries showing that third wave or no third wave, B.1.1.7 or no B.1.1.7 (and there’s lots of P1 in Chile, too), the vaccines are reducing infections, reducing hospitalisations and reducing deaths 🙌
To be clear, the planet as a whole is still far from out of the woods.

Many countries are still battling new outbreaks. The situation in India is dreadful, and it has so far only delivered a first dose to 8% of its population.
(UK 49% ,US 39%, France 19%)
Aside from India, Latin America remains a grim hotspot.

Uruguay has reported a surge in its daily Covid-19 death toll from 1.15 per million on March 1 to 18.55 on April 15, putting it third highest in the world. Deaths are still climbing right across the continent.
Greater availability of Covid-19 data in the western world has at times given the impression the US, UK and Europe have been the hardest hit, but a more comprehensive analysis shows Latin America has unquestionably suffered the most, with all of the top five death tolls worldwide
(NB there’s no comprehensive excess deaths data in India, but local news reports show that Covid deaths are being vastly undercounted in districts across the country, so if India was in that global chart I would it expect it to be climbing the rankings)
But I don’t want do end this thread on a negative note.

This is a story about how vaccines will get us out of this, and several countries are nearly there.

The bottom-right quadrant here is the ultimate goal: more people socialising at bars & cafés, while cases continue to fall
Here’s my full story on how vaccines are prevailing ft.com/content/d71729…

NEW: Is the internet changing our personalities for the worse?

Conscientiousness and extroversion are down, neuroticism up, with young adults leading the charge.

This is a really consequential shift, and there’s a lot going on here, so let’s get into the weeds 🧵 Image
First up, personality analysis can feel vague, and you might well ask why it even matters?

On the first of those, the finding of distinct personality traits is robust. This field of research has been around for decades and holds up pretty well, even across cultures.
On the second, studies consistently find personality shapes life outcomes.

In fact, personality traits — esp conscientiousness and neuroticism — are stronger predictors of career success, divorce and mortality than someone’s socio-economic background or cognitive abilities.

NEW:

There’s been a lot of discussion lately about rising graduate unemployment.

I dug a little closer and a striking story emerged:

Unemployment is climbing among young graduate *men*, but college-educated young women are generally doing okay. Image
In fact, young men with a college degree now have the same unemployment rate as young men who didn’t go to college, completely erasing the graduate employment premium.

Whereas a healthy premium remains for young women. Image
What’s going on?

At first glance, this looks like a case of the growing masses of male computer science graduates being uniquely exposed to the rapid adoption of generative AI in the tech sector, and finding jobs harder to come by than earlier cohorts.

NEW with @KuperSimon

The prevailing narrative around increased injuries and player workload in elite football is wrong.

Players don’t play more football than in the past. What has changed is a sharp rise in intensity of play.

Not more minutes, but each minute exerts more load. Image
Of course, that doesn’t mean a reduction in playing time wouldn’t help. But if one wants to solve the problem, it helps to know the cause.

Fixture schedules are barely busier than in the past, and squad sizes have grown to mean no rise in minutes per player regardless...
...But the recent evolution of much faster-paced gameplay both with and without the ball comes with elevated risk of soft-tissue injuries.

NEW 🧵

The number of people travelling from Europe to the US in recent weeks has plummeted by as much as 35%, as travellers have cancelled plans in response to Trump’s policies and rhetoric, and horror stories from the border. Image
Denmark saw one of the steepest declines, in an indication that anger over Trump’s hostility towards Greenland may be contributing to the steep drop-off in visitor numbers. Image
Corporate quotes are usually pretty dry, but the co-founder of major travel website Kayak wasn’t mincing his words: Image

NEW 🧵

A quick thread of charts showing how Trump’s economic agenda is going so far:

1) Trump has had the same impact on economic uncertainty as a global pandemic. Image
2) That was just the US version.

What’s particularly impressive is that he’s managed this on a global scale.

Starting to get the feeling that “Trump” annotation is going to be the chart equivalent of a layer of volcanic ash in the fossil record. Image
3) US consumers are reacting very very negatively.

These are the worst ratings for any US government’s economic policy since records began. Image

NEW 🧵: Is human intelligence starting to decline?

Recent results from major international tests show that the average person’s capacity to process information, use reasoning and solve novel problems has been falling since around the mid 2010s.

What should we make of this? Image
Nobody would argue that the fundamental biology of the human brain has changed in that time span. People’s underlying intellectual capacity is surely undimmed.

But there is growing evidence that the extent to which people can practically apply that capacity has been diminishing.
For such an important topic, there’s remarkably little long-term data on attention spans, focus etc.

But one source that has consistently tracked this is the Monitoring The Future survey, which finds a steep rise in the % of people struggling to concentrate or learn new things. Image
