It’s also interesting to note that in the U.S., for example, there was no increase in recent years—from 2017 to 2022—while there was a rise from 6% to 10% between 1997 and 2015.

There has been an increase in diagnoses, but there doesn’t appear to be an increase in actual prevalence. The increase in diagnoses is mostly attributed to greater awareness and changes in how the disorder is defined.

This conclusion was part of a consensus statement by leading researchers, summarizing what is currently known about ADHD (published in 2021), and it’s supported by several studies and reviews.

8/ Most breastfeeding studies are correlational – they show things happen together, not why. Like gray hair & disease, or ice cream & shark attacks (spurious links!). We need to be wary of drawing causal conclusions.

7/ Another sibling study, replicating the mostly null findings of the first, demonstrating that in a Western setting, the differences between breastfed and formula fed infants on various outcomes are very small or non-existent

6/ Sibling studies, comparing breastfed vs. non-breastfed siblings, offer a more rigorous approach. Interestingly, these studies often show far fewer significant benefits attributed to breastfeeding than regular studies.

5/ Unraveling cause and effect in parenting studies is tough! Genetics, prenatal environment, and a baby's temperament or disease that can affect breastfeeding, all play a role, making it hard to isolate breastfeeding as the sole driver of observed outcomes

4/ "Liquid gold," "nature's vaccine" – breast milk is lauded for everything from IQ boosts to lower cancer risk. But how much of this is solid science vs. exaggerated claims? Let's dig deeper. #BreastfeedingFacts #CriticalParenting

3/ Even formula websites carry warnings, sometimes bordering on fear-mongering, adding to the immense societal pressure on mothers. #FormulaFeeding #FeedingSupport #fedisbest

2/ The narrative often uses fear: "Don't deprive your child!" This can leave mothers feeling pressured and unsupported, hindering their mental well-being and the ability to make choices that fit their lives. #MomGuilt #InformedConsent

7/ And if you’re wondering if attention is declining in general—
A recent meta-analysis looked into it.
And, if anything, selective and sustained attention in adults may be improving.
But the results were mixed. So let’s not oversell that either.

6/ And come on—8 seconds?
We spend more time than that reading a post or watching a Reel.
The myth doesn't just lack evidence.
It contradicts how we actually behave.
Let’s stop repeating catchy but meaningless claims...

5/ Let’s not forget: attention isn’t fixed.
It depends on:
☕ Alertness
🎧 Distractions
🔥 Motivation
🎯 Relevance
Even in one person, it fluctuates. Measuring it is complex.

4/ Also: There are many types of #attention:
👁 Sustained attention
🎯 Selective attention
🌀 Divided attention
🧠 Executive attention
🔁 Attention switching
So… which one are we supposedly bad at?
There’s a 2019 article titled: “No one knows what attention is.”

3/ The goldfish.
We’ve been told for years they only remember things for 3 seconds.
But it appears that goldfish can remember for days, possibly months.
They can learn (like avoiding shocks) and show quite impressive cognition for fish.
Give goldfish some credit.

2/ Turns out, Microsoft Canada did publish a 2015 report…
But those “8 seconds” weren’t from their research.
They came from a third-party. When a BBC journalist followed the trail, they hit a dead end.
No study. No method. No researcher knew anything about it.

14/ TL;DR: Only children aren't more spoiled, selfish, or maladjusted than anyone else. Early psychologists were wrong. The stereotypes don't hold up. It's time we stopped judging parents for having "just one." #EndTheStigma #ValidatingSingleChildFamilies

13/ Bonus fact: Some studies show having more children beyond the first can decrease a mother's life satisfaction. Yes, mothers' wellbeing matters too! #MaternalMentalHealth #MomTruths #SelfCareMatters

12/ A child's development is shaped by their parents' characteristics, environment, biology, and genetics. If parents of only children happen to be older or more educated, certain traits may appear more often—but that reflects family circumstances, not sibling count. #NuancedParenting

11/ Confounders are crucial. As exemplified by the study showing more siblings = lower divorce risk by 3% per sibling. When they controlled for socioeconomic factors—poof!—the effect disappeared. #ResearchMethods #StatsMatter
comment in response to
post
10/ But these differences were TINY—like "3.58 vs 3.46 on a 1-to-7 scale" tiny. This demonstrates why statistical significance without effect sizes can be so misleading. And they didn't adjust for confounders like socioeconomic status or parental personality. #StatisticalLiteracy #EffectSizeMatters

9/ One massive study with 20,000+ adults found statistically significant differences in personality traits between only children and those with siblings. Sounds damning, right? #BigData #PersonalityPsychology

8/ People also assumed only children would be less generous or helpful. The data? No significant differences in prosocial behavior between only children and those with siblings. #StereotypeDebunked #RaisingKindKids

7/ Recent studies tell the same story. One examined whether people think only children are more narcissistic (they do) and if only children agree (they kinda do too). But when researchers measured actual narcissism? Only children scored LOWER. #MythBusting #PsychologyFacts
comment in response to
post
6/ The verdict? If anything, only children looked better off on these measures. And when compared specifically to kids from two-child families? No meaningful differences whatsoever. #ScienceFacts #ParentingResearch
comment in response to
post
5/ So what does the ACTUAL research say? Are only children really worse off? A comprehensive meta-analysis from 1986 looked at intelligence, sociability, achievement, self-esteem, behavior, leadership, and cooperation. #ResearchMatters #DataOverOpinions

post
4/ Fast forward to today and not much has changed. Only children are still stereotyped as spoiled, lonely, socially awkward narcissists. Parents of one child still hear: "When's the next one coming?" #parentingTips #FamilyPlanning

3/ Alfred Adler joined the party too, using extreme examples of only children who were "sexual perverts" or patricidal to make his point. Very scientific, very objective. 🙄 #PsychHistoryFails

2/ Did you know? Granville Stanley Hall, a prominent psychologist in the early 1900s, once declared that "being an only child is a disease in itself." Yes, really. And that harmful narrative has persisted for over a century. #PsychologyHistory #ParentingMyths

3/ Many effects were model-dependent and lacked replication. Therefore, I wasn't able to come out with any strong conclusions from the analyses. If you read the study and I missed something, please let me know.

2/ Key points
💠Adult concentration gains showed up in basic models, but not in robust ones or regional subsamples.
💠Children’s error increases were inconsistent and reversed in one subsample.
💠Processing speed gains were marginal and not supported by robust analyses.

7/🧵 Why does this matter? Because when we blame parents for mental health conditions, we:
- Increase shame, guilt, and stress
- Delay proper treatment
- Ignore scientific evidence
- Perpetuate harmful myths

6/🧵 We need to let go of the "parenting causes everything" myth. Child development is influenced by multiple factors: genetics, environment, friends, culture, economic status, school, random biological processes, and yes, parenting too - but as ONE piece of the puzzle.

5/🧵 For alcohol addiction, parenting styles (control, warmth) explain only about 1% of differences in addiction patterns. ONE PERCENT! Yet 68% of Americans believe parenting is a major cause.
