‘Close to zero impact’: US study casts doubt on effect of phone ban in schools


Strict bans on mobile phones in schools have “close to zero” impact on student learning and show no evidence of improvements in attendance or online bullying, a study has found.

Researchers at US universities including Stanford and Duke looked at nearly 1,800 US schools where students’ phones were kept in locked pouches and found little or no differences in outcomes compared with similar schools without strict bans.

The report concluded that among schools instituting a ban: “For academic achievement, average effects on test scores are consistently close to zero.”

The results will come as a disappointment to teaching unions and campaigners in England who backed the government’s recent move to restrict the use of mobile phones in schools. A ban is likely to come into force next year.

When the excuse “but what if my mom needs to call me” started working.

Mom can call the school. It worked for 70 years.

Why does the school have to be the middle-man?
Just ban phones during actual classes and let them use it during free periods.
in reply to darkkite

In practice that doesn't work, for the same reasons education hasn't been either. Too few teachers to students, plus the things (phones) are greasily addictive. And we're talking about the youths, lol, dumb-kid brain, most exemplified by teenagers of course. The phase of life that specifically combines "rules are actually just stupid, did you ever notice that?" with "so anyway (I forgot what we were talking about [or any other thing])".

It's really just placing an extremely addictive thing in the pocket of anyone prone to addiction. Kiddos are very naturally weak to resisting those "reward now, consequences later" qualities that drive addiction in the first place. And just like any drug that sells, phones have been engineered (legally, lauded in many ways for doing so) to be super-duper addictive.

"Why don't the children simply smoke the crack pipe in the hallways, between classes, forbidden to do so in class? Why must the school be the middle-man?"

Shallow take homie.

Too few teachers to students,
closer to the actual problem.


but all smartphones have parental controls which is never talked about, but we keep blaming violent media and addictive technology while offering terrible solutions like ID verification and yondr pouches.

This whole thing is a scam on our society with a private company getting taxpayer's money while not actually solving the problem.

these solutions do not teach self-regulation, does not fix algorithmic feeds, does not address home use, does not solve violent or addictive content exposure

I distinctly remember my elementary school not being able to call my parents because their area code wasn't the local area code but okay.

Phones should be allowed in schools, just take them before class starts and hand them back after.

in reply to Powderhorn

This should have been obvious.
Why would you only be able to bully someone digitally in the time you're in the school building? I was in high school when cell phones were first coming out, so I remember school before and during phones, and kids always could and would ignore class if they wanted to. This feels like an attempt to divert blame from school systems not being reactive to generational learning differences and needs.
There are reasons to ban phones in schools, but if you think that doing so is going to prevent bullying or ignoring class, methinks you don't remember pre-phone school.

I didn't realize you're in Canada, and I fully admit I know nothing about Canadian schools or the education system there.

In the US, we have military recruiters in schools, armed officers patrolling halls, metal detectors and backpack checks (for the schools that don't require transparent backpacks), and random locker searches. And this was all from before Trump.

Edit: oh, I forgot my (least) favorite new rule: no talking in the hallway between classes, though it seems like the UK leaned into that more heavily than the US has.

It's a cage for kids, not a place to learn, and it is significantly different than when I was very young. 9/11 happened when I was in middle school, and even in the subsequent 6 years until I graduated high school, it had gone downhill fast.

I have taught in Quebec schools this year, the first full year that cell phones were banned. I have not seen a single student using a phone. The teachers at my schools have also been unanimous in saying that there has been a significant improvement in the student attention, as well as communication and activity between students.

"Hating school made kids want to look at their phones." thats just 100% false. Hating work is not why adults look at their phones nor is it hating public transit or hating driving. 100% phones are a distraction in their own right outside of all exterior effects.
in reply to HubertManne

Hating work is not why adults look at their phones nor is it hating [commuting]


Um, ya sure about that?

Yes, phones are distracting, but distraction is entirely about competing levels of interest, and phones are more interesting than most people's work or commute, and certainly than modern classrooms.

im 100% sure because people are doing it no matter what they are otherwise doing it. So its either they are on their phones because they hate life or smartphones or at least certain apps on them are addictive. its plain to see they are addictive although I will grant that life sucks especially now. Still. the phones be an addiction.
in reply to HubertManne

Addiction usually forms around something that is used for escaping one's problems. True here as well.

And yes, most people are unhappy in life, right now especially.

When I like what I’m doing I don’t get the urge to look at my phone.

in reply to Owl

maybe but as I replied to another then its that people hate life because they are on them all the time. Smartphones or some apps are addictive.
in reply to t3rmit3

"schools have a bunch of structural problems that should be fixed" - yes, agreed 1000%

"schools have a bunch of structural problems that should be fixed, and therefore schools shouldn't ban phones until the structural problems are fixed" - nope. that's a complete non-sequitur.

"fix structural problems with schools" is a gigantic undertaking. it's absolutely worth doing, but it's the kind of thing that will take many many years, and effort across many many different fronts. it's not like Congress can pass the Fix Structural Problems In Schools Act of 2026 this summer and then starting this September schools are now fixed.

"you can't do that small change until the all the larger problems are fixed" ends up being essentially a thought-terminating cliche.

Keep in mind the paper is a white paper (not peer reviewed) and it is sponsored by the Bezos Family Foundation and Walton Family. Personally taking it with a grain of salt and waiting for some experts to weigh in who are not economists (like most of the authors are) since I don’t feel like combing through this 100 page document.

Interesting that Guardian didn’t see fit to mention it was a white paper unless I missed something.
in reply to reallykindasorta

Just on the epistemological tip, how is it being a white paper more relevant than having Bezos, Waltons, and more (of the same) sponsors?

Typically when a news article mentions a “study” it’s a peer reviewed research article. If it’s a white paper or a working paper that is typically pointed out. Leaving that detail out is notable and probably a purposeful decision by my reckoning.

Generally they don’t mention conflicts of interest even if they’re listed so that bit isn’t especially atypical here to me.

in reply to reallykindasorta

Okay. Again, from the standpoint of how to get at what's knowable - my complaint here with The Guardian is that they aren't pointing out the things they should be, at all, and that the white paper nature (from such "sources") merits exactly nothing. No further draft on any such topic from such sources could ever be credible.

Your "typical / atypical" is you getting to my point for me, or maybe we just agree.

I think we agree! I was the original commenter in this comment thread and posted the screenshot of the sponsorship issue

in reply to PolarKraken

I guess I felt like the evidence spoke for itself, my aim was to communicate that Guardian was acting in bad faith in their reporting of this. “Grain of salt” was just colloquial language. I hadn’t read the paper so I couldn’t speak to the actual contents.

I’m also disappointed that Stanford, Upenn, and Duke would be okay with this (there are rules for putting your university affiliation on illegitimate research to make it seem legitimate). I would kind of expect it from Stanford (who also sponsored the research) tbh but not Duke or Upenn.

No wonder people are losing faith in the scientific establishment. If anyone reading this goes to one of those universities you should email the VPR/OPR office to complain. This is eroding your legitimacy too.

This whole thing is an excellent example of how corporations wield their ‘soft power’ to try to make their policies seem reasonable.

Edit: And U. Michigan! Good lord.

Okay got it, sounds like I just kinda jumped down your throat then. "How dare this person not dunk on those folks as hard as I think they should!" (that's me lol)

Cheers. Thanks for the info.

Edit: I will say, Guardian and lots of others remain able to coast on an assumption of good will and journalistic integrity that I don't believe is there. Maybe it once was earned, I'm not a journalistic historian. But it seems much like old school enshittification, where a brand builds up a lot of credibility slowly over time, then the things that made consumers like it get quietly swapped out for shittier "parts" and it takes a long time for consumers to update their understanding of the brand.

The Guardian is not a credible journalistic institution, I wish it were, but I'm glad folks like you are noticing.

Nah you’re completely right it merits an angrier tone, it’s just so exhausting!

Agreed on the lack of legitimate publications. Pretty much every mainstream news source is compromised. You just have to piece together the truth from independent sources and read between the lines.

They make their agenda kind of transparent just in what they do choose to cover (like Bezos’ papers hyping billionaires and AI) vs what they choose not to cover (perpetual and well documented rape murder and other war crimes by Israel).

in reply to reallykindasorta

Couldn't agree more, oddly enough to understand what they are saying you have to zoom way out, see what's not being said, see how phrasing is implicitly shaping their narrative, etc. All the subtle techniques eventually produce enough evidence to sum up one's observations into a really big and gross elephant. Standing right there. And somehow kind of invisible to many. Formerly to oneself.

It's difficult, and I mean, big surprise lol, they're basically engineered to be that way, it's all so tiring like ya said.


No hate to elephants, elephants are fucking great

That’s such a great description, you somehow start being able to see through the mist if you pay attention to a topic for long enough and the details coalesce into a clear picture of the situation.

I’m sure the wool is still over my eyes on some important things but my bullshit detector is constantly improving.

Also, agreed, let’s put the elephants in charge.

Thanks, it's at least a familiar metaphor (-ish), but I've always struggled to describe the feeling well. I do think something like "seeing a shape in the mist" does a good job capturing it too. How it's obviously there but still hard to identify, easy for others to dismiss, etc. It's all the things you should be seeing but don't.

Anyway, same, on the wool and BS detector. How do you like your instance btw, on precisely that topic? I don't know a lot of details about that one but I feel like I see good info and takes from y'all more often than not. What's your experience there been?

We are pretty small and I haven’t seen any real conflict play out within the community in my time here. The admins are anarchist and I think we agree on the things that matter most. The community isn’t explicitly anarchist (we want to be a good landing pad for all solarpunks). I haven’t seen misplaced hatred or bigotry coming out of our community. I’m a pretty happy camper.

I had seen the LLC thing and raised my eyebrows at the projects listed on their wiki, but didn’t see the META board thing, good catch. Everything is both awful and exactly as expected.

Wow that casts a healthy dose of doubt on the entire study. Thank you for pointing it all out so thoroughly!

wow. I was just gonna say doubt based on my experience substitute teaching.
in reply to spit_evil_olive_tips

This paper is of the same caliber as all of those cigarettes are safe papers from the 70s. Funded propganada with a PR firm plying it to a willing news source.

As an aside, is the Guardian becoming a shit rag? Lately (last year or two) I've noticed a huge dip in their quality.

in reply to its_me_xiphos

in reply to spit_evil_olive_tips

That is an excellent breakdown. I'm glad I'm not the only one noticing these posts. Poor data analysis being published or claims taken at face value.

I interacted with the Guardian editorial team once in the UK. I had a dataset on academic censoring and we were focusing on sharing the qualitative responses. All seemed on the up and up but we never moved forward for a variety of reasons with the story. Editors and the journalist were great. Tough questions, good insight, etc. Seemed like a good outlet. But that was earlier 2025 and in less than a year, I read that trash we are discussing.

in reply to Powderhorn

It also found a rise in suspensions and a dip in students’ feelings of wellbeing in the first year after a ban as schools adapted to the change. “Over time, however, disciplinary impacts fade and wellbeing rebounds, becoming positive in subsequent years,” the report said.


So it sounds like the winning play is to not give them phones in the first place. Then you skip straight to positive impacts without going through the negative ones first.

Thanks for posting this. It's good to know that the propaganda still flows
