Captive Thought Journal
A private journal that helps you sort out what's on your mind.
A high school class writes in the Captive Thought Journal once a week. Only the student reads what they write.
Why a journal? A thought that is written down can be looked at, sorted, and decided on, instead of going around in circles.
What it is
What is the Captive Thought Journal?
The Captive Thought Journal is a private writing exercise for high school students. Once a week, your class sets aside about 35 minutes for it.
You finish five sentences that start for you, like "I worry" or "I'm grateful for". Then you sort what you wrote until you can see what is really on your mind.
It opens in the web browser on a school laptop. There is nothing to download, and you don't make an account.
Why it matters
Why bother writing it down?
Think about the junk drawer in a kitchen. Things go in one at a time, nobody sorts them, and one day it won't close. Your mind fills up the same way, with worries, plans and half-finished thoughts, and it was never built to hold all of it.
When a thought is on the page, you can look at it from the outside. You can decide that it doesn't matter, that it matters a lot, or that it belongs with something else. That is hard to do while it is still going around in your head.
Each sentence starter comes from a study of young people. Here are four of them.
- I feel Teens who can name their feelings more exactly tend to be less depressed. Dunning et al. 2025, Journal of Adolescence
- I think Teens who wrote about their thoughts and feelings had less emotional distress. Travagin, Margola & Revenson 2015, Clinical Psychology Review
- I worry 9th graders who wrote down their worries before a big test scored higher. Ramirez & Beilock 2011, Science
- I'm grateful for Students who wrote what they were grateful for liked school more. Froh, Sefick & Emmons 2008, Journal of School Psychology
Each starter has its own study. Doing five short starters in one sitting has not been tested as a whole yet.
How it works
What happens in a session
- You sign in. Your teacher puts a class code on the board, and you type it with your first name. This takes about 5 minutes with the welcome.
- You write. You finish five sentence starters, one at a time. A few words is enough, and you can write as much as you like. This takes about 10 minutes.
- You keep or clear. Each answer becomes one of your thoughts. You keep the ones that matter and clear the ones you don't need.
- You name groups. You give each thought you kept a group name in your own words, like School or Friends.
- You put them in order. You choose between two answers at a time, and each thought gets a place from 1 to 8.
- You describe. You write one sentence about what each group means to you. You can skip one you would rather not describe.
- You choose what matters most. You put your groups in order, two at a time.
- You sum it up. You look at everything together and write what was on your mind today. That is your journal entry, and it is gone when you close the tab.
The sorting takes about 15 minutes. At the end, your teacher reminds the class that the counselor is there and that 988 is open any time.
Questions
Questions students ask
Who sees what I write
Who can read what I write?
Only you. It stays on the laptop you are using. Your teacher, your counselor, your school and the people who made the journal never see it.
What does my teacher see?
Your teacher sees how many laptops started and how many finished today, and nothing else. Any number from 1 to 4 shows as "fewer than 5", so a count can't point at one student.
Does AI read it?
No. No AI reads what you write.
Is my entry saved anywhere?
No. Nothing you type is saved or sent. When you close the tab, your entry is gone.
Why does it ask for my first name?
It is there in case you write something that sounds like you might be in danger. Then your teacher and your counselor get a note with your first name, so they know who to check in with. Your name is not sent at any other time.
What is the class code for?
It tells the journal which class you are in. That way you get your class's five starters for the week, and your teacher's count goes up when you start and finish.
Does the laptop remember me?
The laptop keeps a random number, not your name. It is there so the class count is a count of laptops.
Do I need an account or an email?
No. You only type the class code from the board and your first name.
Staying safe
What if I write that I'm in danger?
Every line you write is checked on the laptop itself. If it sounds like you might be in danger, a card tells you that your teacher or counselor will check in with you soon. They get a note with your first name and your class. They never see your words.
Will the police be called?
No. Police are not part of it.
Can I get in trouble for what I write?
No one reads your words, so nothing you write can be held against you. The only thing that ever leaves the laptop is the check-in note above, and it never includes your words.
What if I need to talk to someone right now?
Tell your teacher or your school counselor. You can also call or text 988 at any time, day or night.
Is this instead of talking to a counselor?
No. The journal is a writing exercise, and nobody reads it, so it can't answer you back. If something is weighing on you, your counselor is the person to talk to.
The writing
What is a sentence starter?
It is the first few words of a sentence, like "I worry" or "I'm grateful for". You finish the sentence in your own words.
How much do I have to write?
You need at least three words to go on. After that, you can write as much as you like.
Can I skip a starter?
No, each one needs a few words before you can go on. If one is hard, a short and honest answer is enough.
Does spelling or grammar count?
No. Nobody grades it, because nobody sees it.
Is there a timer?
No clock counts down while you write. Your class sets aside about 10 minutes for the five starters.
What is the line under each starter?
It names the study behind that starter. You can tap "source" to see who did the study and who was in it.
Are the starters the same every week?
No. There are 20 of them. You get a different five each week for four weeks, and then they come around again.
What if I don't know what to write?
Write the first true thing that comes to mind. A few words is enough to go on.
The sorting
Why do I sort my thoughts?
Writing gets your thoughts out of your head. Sorting shows you which ones matter to you right now and which ones you can let go.
What does "Clear it" mean?
You throw a thought off the screen because you don't need to keep it. Letting go of it is the point.
What if I want to keep everything?
That is fine. You can keep every thought you wrote.
What is a group name?
It is a word or two, in your own words, that fits a thought you kept, like School, Friends or Sports.
What do the places from 1 to 8 mean?
Place 1 is what matters most to you right now, and place 8 matters least. You get there by choosing between two answers at a time.
Can I skip describing a group?
Yes. When you write one sentence about each group, you can skip a group you would rather not describe.
What do I do with my summary?
It is for you. At the end you look at everything together and write what was on your mind today. Read it, notice it, and then close the tab.
About the journal
Why is it called Captive Thought?
Your thoughts run loose, and the idea is to catch each one and decide what to do with it.
How often do we do it?
Once a week, in class. A session takes about 35 minutes.
Who is the explorer who talks to me?
That is AHA, the journal's guide. He tells you what each step is for.
Do I need to download anything?
No. The journal opens in the web browser on a school laptop.
Has this been tested?
Each of the 20 starters comes from its own study of young people, and the line under each starter names it. Doing five short starters in one sitting, the way the journal does, has not been tested as a whole yet.
