Frank and Celia booked the family barbecue on a Sunday in March, at the kitchen table, each with their own instrument.
Celia took the planner out of her bag. Hard cover, ribbon bookmark, a pen clipped to the spiral that nobody else in the house was allowed to touch. On April 14th, in the handwriting of a former schoolteacher, she wrote: "Barbecue, Mum's, 1pm".
Frank typed it into his phone. He misspelled "barbecue", autocorrect offered "barbecued", he accepted. He set an alert for half past twelve.
"You'll never remember that," said Celia.
"I won't. It will."
"It who?"
"The phone."
Celia made the face that people who write by hand make at people who don't.
And she was right. A month later, asked about it, Celia knew the date, the time, who was bringing the potato salad, and that cousin Nigel would not be coming because he was not speaking to his mother-in-law. Frank did not even know there was a barbecue.
On the 14th, at half past twelve, Frank's phone buzzed: "Barbecued, Mum's, 1pm". He got the message, grabbed the car keys and arrived before the meat did.
Celia was in the supermarket queue. She knew everything about the barbecue. She just did not know it was today.
The difference in one sentence
Celia had the first kind. Frank outsourced the second. Knowing about an appointment and remembering it in the minute it matters are skills that do not live in the same place.
The study everyone quotes measured something else
The reputation of handwriting comes almost entirely from a 2014 paper in Psychological Science. Pam Mueller and Daniel Oppenheimer had students watch talks and take notes either by hand or on a laptop; the handwriters did better on conceptual questions. The proposed explanation: on a keyboard we transcribe, with a pen we summarise.
In 2019, Kayla Morehead, John Dunlosky and Katherine Rawson ran the experiment again and did not find the advantage consistently. The story of that replication is already told in the piece on bullet journaling; what matters here is a different detail.
Both studies are about learning a lecture. Nobody in them had to remember a dentist appointment on Tuesday. Using that result to pick a planner is like choosing running shoes by your gymnastics score: same body, different event.
The study that actually measured a planner
It exists, and it is far less famous.
In 2021, Keita Umejima and colleagues at the University of Tokyo published an experiment with 48 university students in Frontiers in Behavioral Neuroscience. Each one read fictional conversations containing fourteen appointments (seven academic, seven personal) and entered them into a monthly calendar: on paper, on a tablet with a stylus, or on a phone. An hour later, with a distracting task in between, they answered questions about the appointments inside an MRI scanner.
The results, without decoration:
- Speed: the paper group wrote faster: about 11 minutes, against 14 on the tablet and 16 on the phone, according to the university itself.
- Overall accuracy: no significant difference between the three groups.
- Easy questions: paper scored higher, and only when compared with the tablet.
- Brain: more activation in the paper group during recall, in areas linked to memory, language and vision.
The headline that went around was "paper boosts memory". What the study showed was a more active brain arriving at a similar score.
What about the 2024 EEG study?
A paper by Van der Weel and Van der Meer, published in 2024 in Frontiers in Psychology, recorded the brains of 36 students writing words by hand or typing them, and found more widespread connectivity when writing by hand.
Two details change how to read it. The handwriting was done with a digital pen, on a screen. And nobody measured whether people remembered anything afterwards. It is a study of hand versus keyboard, not paper versus phone, and of brain activity, not memory.
How to choose
| Paper | Digital | |
|---|---|---|
| Helps you keep the content | A little, maybe | Less, maybe |
| Alerts you at the right time | No | Yes |
| Speed of writing it down | Faster in the 2021 study | Slower in the same study |
| Search and recurrence | None | Automatic |
| Typical failure | Staying in the drawer | Becoming an ignored notification |
The honest limits
These studies are small (48 and 36 people), run with university students, in a lab, measuring what happens over minutes or an hour. None of them followed people using paper or digital planners for months and counted missed appointments. That is the question most of us actually want answered, and nobody has measured it.
Until then, the honest sentence is a modest one: the hand may help you encode; paper does not help you remember on time.
Why I kept both halves
I am Celia in almost everything: I write by hand, I remember what I wrote, and I have still turned up late to appointments I knew by heart. The problem was never knowing. It was being reminded in the right minute.
ASB took Frank's half: you send the sentence however it comes out, typos included, and it comes back to talk to you on WhatsApp when the time arrives.
