Resilience is not something purely individual: how some young people can overcome their difficult situation.

Why do some young people manage to do well in school despite difficult home situations, poverty, migration, or other forms of vulnerability? In recent years, when discussing this question, you quickly end up talking about resilience. And it is true that some young people seem better able to cope with setbacks. They persevere, remain motivated,… Read More Resilience is not something purely individual: how some young people can overcome their difficult situation.

Can working from home lead to more children? Correlation and causality

Correlation is not causality. It is perhaps one of the most frequently used phrases when I write about research here, and I have noticed that it can sometimes even irritate people. But a new NBER working paper by Andrew Johnston beautifully illustrates that the story usually only begins there. Johnston’s question is simple: can working… Read More Can working from home lead to more children? Correlation and causality

10-year-olds are more often tired at school (and that is bad news)

Last Friday, I was in Warsaw with a large group of researchers to bring together different findings on the global decline in learning outcomes. Many different explanations were discussed. I added a new one myself, which I hope to tell you more about soon. In the meantime, I would like to share the already published… Read More 10-year-olds are more often tired at school (and that is bad news)

US watchdog warns about ChatGPT for teens

Let’s be honest, young people are using AI chatbots en masse. Via Axios, I found this new assessment by the US organisation Common Sense Media. They discovered that 67 per cent of children aged 9 to 17 years old in the USA have used AI chatbots. 40 percent name ChatGPT as one of such tools.… Read More US watchdog warns about ChatGPT for teens

A parent program seemed to stop working after a few years. Until the schools closed.

Investing in early childhood education through various programs happens in many places, but thanks to James Heckman, we know that sustaining — maintaining — such investments is important, because otherwise their effects can fade. That already explains part of the title of this post, which almost sounds like the beginning of a riddle. It is… Read More A parent program seemed to stop working after a few years. Until the schools closed.

Social media and young people’s mental health: are we missing a step?

It is a hot topic in the media, and I have written about it several times before: the relationship between social media and young people’s mental health. Mental health among young people has been deteriorating, and for some time now we have been looking for explanations (deliberately plural). Anyone looking for a simple answer to… Read More Social media and young people’s mental health: are we missing a step?

Children’s books show many emotions in words, but far fewer in pictures

A character can be afraid, or angry, maybe sad. You can read this clearly in the children’s book. But if you look at the picture on the same page… There is a good chance you will see someone who looks… strikingly calm or happy. That is the finding of a new NBER working paper by… Read More Children’s books show many emotions in words, but far fewer in pictures

Why are there more diagnoses of ADHD and autism now?

It is the basis for discussions about overdiagnosis. Every now and then, you even read possible explanations that seem more like conspiracy theories. Yet it is a fact: many more children and young people are diagnosed with ADHD or autism today than, say, ten or twenty years ago. In Denmark, for example, the number of… Read More Why are there more diagnoses of ADHD and autism now?

Can childhood language ability predict where we end up 30 years later?

On Friday, my wife sent me this study. James Bruce Tomblin and colleagues followed a group of people for about thirty years. They observed them from kindergarten until their mid-thirties. The researchers wanted to know whether differences in oral language ability at a young age could predict the socioeconomic position people would reach much later… Read More Can childhood language ability predict where we end up 30 years later?

Genes matter for personality, but they don’t determine it

After all the PISA hype, here is a study that is only indirectly related to education! A massive new study in Nature provides important new insights into the link between our personality and our genes. For this, the (truly ridiculous number of) researchers combined data from 46 cohorts. The number of participants ranged from well… Read More Genes matter for personality, but they don’t determine it
