Should children do chores? The science says yes.


It's easy to assume chores are just about a tidy house. But decades of research suggest they're one of the most quietly powerful things we can give a child — and the findings are genuinely surprising.


The headline result: in a landmark study following children into their mid-20s, the single best predictor of adult success wasn't intelligence or motivation. It was having done chores from a young age. (Rossmann, University of Minnesota)


And timing matters. Children who began around age 3–4 did best of all. Strikingly, those who only started at 15–16 saw little benefit — so the habit is best built early.


Why does something so small matter so much? Because chores are real practice for the things that count later: responsibility, planning, follow-through, and the quiet confidence that comes from being capable. Psychologists call it self-efficacy — "I can do hard things." Deeper still, helping out gives children the feeling of being a needed contributor to the family. They feel they matter to the group.


A few things that help:


Make it a contribution, not a punishment. Chores handed out as a consequence for misbehaving start to feel like a penalty, rather than a normal way of pitching in.


And don't wait for the "right" age. Earlier is better — so whatever age your child is today, this is the youngest they'll ever be. Start small, expect mess, and let them do it imperfectly. The doing is the point.

A small job today. A capable adult tomorrow.

Three ways culture rewires how you see


We tend to assume the mind works the same everywhere. But cross-cultural psychology keeps finding something stranger: culture shapes not just what we think, but how we literally perceive the world. Three examples.


One — attention. Shown the same scene, people from Western cultures tend to fix on the main object first; those from East Asian cultures more often take in the whole context and how things relate. Culture nudges where the eye goes.


Two — illusions aren't universal. The famous Müller-Lyer arrows fool people raised among "carpentered," right-angled buildings far more than those raised in other environments. Even basic perception is partly learned.


Three — the colour line. Languages carve up the spectrum differently. Where a language has no separate word for blue and green, people can be slower to tell them apart — and quicker at distinctions their language does mark. The border between colours is partly drawn by words.


None of this ranks anyone. These are tendencies, on average — not rules about any one person. But together they reveal something humbling: the way you see the world is shaped by where you grew up in it.


Your "normal" is learned. Send this to someone whose mind works a little differently to yours.

Two real differences. One big misunderstanding.


Psychology has found some genuinely robust differences between males and females, on average. But "on average" is doing an enormous amount of work in that sentence — and misreading it is where the trouble starts.


Here's the key idea: an average is not a person. Even when two groups differ, their distributions overlap hugely. Most people fall in the shared middle, and plenty in one group sit well inside the other.


Take two of the most replicated findings in the field.


People versus things. On average, women lean a little more towards people-focused interests, men towards thing-focused ones (Su et al., 2009, over 500,000 people). It's one of the larger differences psychology has measured — yet plenty of women love how things work, and plenty of men are drawn to people. Both are completely typical.


Physical aggression. From early childhood, boys show more direct physical aggression than girls, on average — one of the larger and most consistent behavioural differences, seen across cultures (Archer, 2004). But it's real and sizeable, not destiny: plenty of boys are gentle, some girls are highly physical, and for most it eases with age.


Where do these come from? A mix of biology, upbringing, culture and expectation, woven together from birth. Psychology can't cleanly separate them — and for any one person, it doesn't need to.


Because the most useful question is never "what do males or females do?" It's "who is this person?"


Averages describe groups. People are individuals — and the differences are small next to everything any two of us can share.


Save this as a reminder to see the person, not the category — and share it with someone who'd find it interesting.

Back for round two. Four more myths — how many can you get right? (Catch Part 1 on the grid if you missed it.)


"Vaccines are part of the cause." → FALSE. More than a dozen large studies, across millions of children, found no link. The 1998 claim was retracted and discredited. Diagnosis simply happens around the age of routine jabs — coincidence, not cause.


"Boys are more likely to be diagnosed as autistic than girls." → TRUE… but it's misleading. Boys are diagnosed 3–4× more often. But much of that gap is girls being missed or masking — not such a large true difference.


"Children grow out of autism." → FALSE. Autism is lifelong. What changes is understanding, support, and the tools a person builds — not the wiring itself.


"Autistic people don't feel empathy." → FALSE. A harmful myth. Many autistic people feel empathy intensely — they may simply express or process it differently.


So how did you score across both parts? Tell us in the comments.

Think you can separate the myths from the science? Keep count as you go — four statements, how many can you get right?


"Autism is becoming more common." → TRUE… but mostly on paper. In Ireland, diagnoses have gone from about 1 in 65 to roughly 1 in 20 — but that's mostly better detection, not a sudden wave of new cases.


"Autism can't be reliably diagnosed in young children." → FALSE. A skilled team can diagnose reliably by age 2, with signs often visible from 18 months. Yet the average diagnosis comes years later — and earlier support, while the brain is most adaptable, can make a real difference.


"Autism is caused by bad parenting." → FALSE. This is the long-discredited "refrigerator mother" myth. Autism is highly heritable — it is not caused by how a child is raised.


"You can be autistic and only find out as an adult." → TRUE. Many adults are diagnosed late — especially women — having spent years masking or being misunderstood. They were always autistic. No one had noticed.


So — how did you do? Comment your score out of 4 below, then follow so you don't miss Part 2, where we tackle vaccines, the gender gap, and more.

Is autism actually increasing?


It's one of the most charged questions in child development right now — and the honest answer is more reassuring than the headlines suggest.


The numbers are real. In Ireland, autism among schoolchildren has risen roughly threefold in under a decade — from about 1 in 65 to around 1 in 20. So what's going on?


Two things are true at once.


Mostly, we've become far better at recognising it. In 2013, the diagnostic manual folded several separate diagnoses — including Asperger's — into one broad spectrum. Awareness has grown. And diagnosis is rising fastest in those long overlooked, especially girls, who often present differently. The children were always there.


But it's not purely a detection story. Genes set the stage — autism is around 60–90% heritable — yet up to 40–50% of the variance may be environmental. Some of those factors have genuinely changed: the strongest established one is advanced parental age, which has risen steadily, alongside certain prenatal and birth-related factors.


What it is not: vaccines. More than a dozen large studies, across millions of children, found no link; the 1998 claim was retracted. And not paracetamol — a Swedish study of 2.4 million children saw the apparent link vanish once siblings were compared. Major medical bodies still recommend it as the safest option in pregnancy.


Why does this matter? Because "epidemic" language frightens parents, feeds stigma, and sends people chasing causes the evidence has already ruled out. The calmer truth helps more children get understood.

Is autism actually increasing?


Diagnoses have risen sharply — in Ireland, from about 1 in 65 schoolchildren to roughly 1 in 20 in under a decade. But the reasons are more reassuring than the headlines suggest.


The honest answer has two layers.


Mostly, it's better detection. In 2013 the diagnostic manual folded several separate diagnoses — including Asperger's — into one broad spectrum. Awareness has grown enormously. And diagnosis is rising fastest in those we used to overlook, especially girls. The children were always there. We're simply seeing them now.


But it's not purely a detection story. Genes set the stage — autism is around 60–90% heritable — yet up to 40–50% of the variance may be environmental.

What it is not: vaccines. More than a dozen large studies, across millions of children, found no link, and the original 1998 claim was retracted. And not paracetamol either — a Swedish study of 2.4 million children saw the apparent link vanish once siblings were compared, and major medical bodies still recommend it as the safest option in pregnancy.


Why does the framing matter? Because calling it an "epidemic of toxins" frightens parents, feeds stigma, and sends people chasing causes the evidence has already ruled out. The calmer truth helps more children get understood.

You can't go over it. You can't go under it. You have to go through it.


When a child is anxious, every instinct says rescue them. Let them stay home. Skip the party. Take the long way around the dog. It comes from love — and it works, for a few minutes.


But avoidance is a trap. Each time a child avoids the thing they fear, the brain learns it really was dangerous — so the fear grows. The birthday party becomes all parties. The dog becomes all dogs. Avoidance feels like safety, but it quietly shrinks the life a child is willing to live.


The way out is through. Not forcing, not flooding — small, supported steps at a pace that challenges without overwhelming. Look at the dog from across the road today. A little closer next week. Gradual, structured exposure is the most evidence-backed approach to childhood anxiety, because the brain learns safety through experience, not avoidance.


For parents: around 97% of mothers and 88% of fathers accommodate their child's fears. It's normal and it's loving. Anxiety comes from biology, temperament and experience — not parenting. You are not the cause, but you can be a powerful part of the solution.


For teachers: safety can backfire. Remove every risk — no climbing, no rough games, no ball games — and you don't remove the fear. You confirm it. The yard is where resilience is built, one scraped knee at a time.


Brave isn't the absence of fear. It's going through it.


If anxiety is shrinking your child's world, a clinical or child psychologist can help. You don't have to work it out alone.

"My child has been diagnosed with severe dyslexia. Does this mean…"


If you're a parent who's just heard those words, the honest answer is more hopeful than you might expect.


"Severe" measures the reading — not the potential. It means a child reads and spells in roughly the lowest 2% for their age, despite good teaching and genuine effort. It's a neurobiological difference in how the brain processes print, present before school even begins. It is not laziness, and it is not a lack of intelligence. Many children with severe dyslexia are bright, capable, and articulate.


Three things change the whole trajectory:


Early identification. The brain is most plastic in early childhood, and intervention in early primary (junior infants–1st class) can be around twice as effective as waiting until middle primary. The signs can be spotted before a child has repeatedly struggled.


Protecting self-esteem. The deepest risk isn't the reading itself — it's a child quietly deciding they're "stupid." Early identification, and helping them understand what dyslexia actually is, protects against that.


The right tools. Text-to-speech and speech-to-text separate reading from understanding — a child can absorb ideas and write a story before they can spell it. In State exams, the RACE scheme provides reading help, writing support, and a spelling waiver; support continues into college through DARE.


A child with severe dyslexia learns differently. That is not the same as achieving less.


If you have concerns, talk to your child's school about a NEPS assessment — or explore a private assessment.
