Write it down, name it, crumple it and toss it
The Emotion Trash Bin is a lined sheet of paper on your screen. You write down what made you angry, the unfair thing someone said, or the worry that won't leave your head, then crumple the paper into a wire bin or feed it to a shredder. What you write is never saved or sent anywhere. The moment you toss it, the text box is swapped for a fresh sheet, so even Undo (Ctrl+Z) can't bring it back.
This version adds a way to see what changed. Before writing you can name what you feel (up to three names) and rate how heavy it feels from 0 to 10. After you toss the paper, rate it again and the tool shows the two bars side by side. Say you pick "Anger" and "Unfairness", toss at a 7, and then rate it a 4: you'll see "It's 3 lighter." Last, you can follow three slow breaths, 4 seconds in and 6 seconds out (30 seconds in all).
Why might writing it down and throwing it away help?
In a 2024 study from Nagoya University (Kanaya and Kawai), researchers made participants angry on purpose with an insulting evaluation of their writing, then had them write down their thoughts about it on paper for 3 minutes. Some of them crumpled the paper and threw it in a trash can (experiment 1, 50 people analysed). In a second experiment, others fed it into a shredder (experiment 2, 48 people). The rest kept the paper in a clear folder on the desk. In both experiments, the anger of those who threw the paper away dropped back to its level before the insult, while the anger of those who kept it stayed higher.
- Treating thoughts like objects: in a 2013 study (Briñol and colleagues), people who tore up a paper with their thoughts about their own body used those thoughts less when judging, and people who kept the paper used them more. The effect was larger when people actually did it than when they only imagined it.
- Putting a name on it: a brain imaging study found that simply putting feelings into words (affect labeling) reduced amygdala activity in response to upsetting pictures (Lieberman and colleagues, 2007). The feeling-name chips in this tool are there for that step.
- Writing it out: a meta-analysis of 146 randomized studies on disclosing feelings in writing (Frattaroli, 2006) found a small but real average effect (r = .075). It's best seen as something to do often and briefly, not as a big fix.
Some ways of letting anger out can backfire. A meta-analysis of 154 studies and 10,189 people on anger management (Kjærvik and Bushman, 2024) found that activities that lower arousal, such as deep breathing, reduced anger (g = −0.63), while activities that raise arousal, such as venting or going for a run, had no effect (g = −0.02). That's why this tool suggests three breaths after you toss the paper and doesn't encourage replaying the scene and writing harder.
How to use it
- Name it (optional): pick up to three words close to what you feel, such as Anger, Unfairness or Anxiety. The names you choose are stamped at the top of the paper.
- Rate the weight (optional): move the "How heavy it feels before tossing" bar. 0 is light and 10 is very heavy. If you don't touch the bar, no comparison is shown.
- Write: what happened, and what did you want to say at the time? In the study, people wrote for 3 minutes and reread for 30 seconds before throwing the paper away. Spelling and order don't matter.
- Toss: choose "Crumple and toss" or "Put in the shredder" and press the button. From the keyboard, Ctrl+Enter works too (⌘+Enter on a Mac). Plain Enter just starts a new line.
- Rate again: after tossing, move the "How heavy does it feel now?" bar and the two bars are compared.
- Breathe: press "Take three breaths" and follow the circle as it grows for 4 seconds and shrinks for 6, three times. If something is left, use "Take a new sheet" and write again.
How the study threw the paper away
The tool's two ways of tossing come straight from the study's experimental conditions. In the study the shredder's bin was clear so the cut strips were visible, and the wire bin in the tool is drawn so you can see tossed papers pile up too.
| Study | What participants did | Result | In this tool |
|---|---|---|---|
| Kanaya and Kawai 2024, experiment 1 | Wrote about the anger for 3 minutes, reread for 30 seconds, then crumpled the paper and threw it in a trash can (50 people) | Anger fell to its level before the insult; the group that kept the paper stayed higher | Crumple and toss |
| Kanaya and Kawai 2024, experiment 2 | Wrote the same way, then put the paper in a shredder (48 people) | Same result as experiment 1 | Put in the shredder |
| Briñol et al. 2013 | Tore up a paper with their thoughts vs. kept it | Discarded thoughts were used less in judgments; larger when actually done than imagined | Tossed papers are never shown again |
| Lieberman et al. 2007 | Chose a feeling word while viewing upsetting pictures | Less amygdala activity | Feeling-name chips (up to three) |
| Kjærvik and Bushman 2024 | Compared anger management activities across 154 studies | Only activities that lower arousal worked | Three breaths after tossing (30 seconds) |
Note These studies used real paper. Kanaya and Kawai also state as a limitation that they did not test a digital device such as a word processor or smartphone. Whether tossing a note on a screen works the same way hasn't been shown, so if you have a sheet of paper nearby, trying it with real paper is a good idea too.
Telling similar feelings apart
If you can't decide on a name, use the table below. It isn't a set of right answers, just a way to find the word closest to how you feel now.
| Name | Often felt when | Try starting with |
|---|---|---|
| Anger | Someone crossed a line or took something that was yours | "I'm angry because of ___, because..." |
| Unfairness | You were blamed for something you didn't do, or no one understood your side | "What actually happened was this, and I never got to say it." |
| Annoyance | Small frustrations pile up or things keep getting stuck | "What kept getting to me today was..." |
| Anxiety | Your mind is racing but you can't pin down what you're afraid of | "The scene I'm most afraid of right now is..." |
| Worry | One specific thing that might happen is weighing on you | "If ___ happens... what I could do then is..." |
| Disappointment | Someone close didn't show up for you the way you hoped | "I wanted ___ to do this for me." |
| Sadness | You feel you've lost something or that something has ended | "What I miss is..." |
| Loneliness | You're surrounded by people but feel no one knows what's going on inside you | "Something I haven't told anyone lately is..." |
| Exhaustion | Rest doesn't help and everything feels heavy | "What I'd like to put down right now is..." |
| Shame | You made a mistake, or felt small in someone else's eyes | "When I replay that moment..." |
When "emotional dumping" means a person
Outside of tools like this one, "emotional dumping" usually describes something that happens between people: one person unloads complaints and anger on another without checking whether the listener has the room to hear it. If every conversation is spent on someone else's venting and there's never space for your own story, the listener gets worn out and the relationship tilts to one side.
- If you're the one always listening: you can say how much time and energy you have before the conversation starts. Something specific like "I can listen for ten minutes right now" is usually easier on the relationship than going quiet or pulling away.
- If you're the one unloading: words poured out at the peak of anger land heavily on the other person too. Write it on paper first and toss it, then bring only what's left to a person. The conversation tends to be shorter and clearer.
None of this means talking to people is wrong. Having someone who will listen matters a lot. This tool is for the step before that, or for the hours when no one is available: a place to set down the first wave of anger.
What is and isn't stored
| Item | Where it stays | Details |
|---|---|---|
| The text you write | Nowhere | When you toss it, the text box is replaced with a new one, which also clears the undo history. The flying paper image is removed when the animation ends. No request is sent to a server. |
| Crisis phrase check | Nowhere | Whether your text contains phrases like "I want to die" is checked only inside this browser. If it does, the helpline numbers are shown prominently after you toss. |
| Feeling names and weight | This tab | They appear in the "Papers tossed in this tab" list with the time and method. They disappear when you close or reload the tab. |
| Number of papers tossed | This browser's storage | Only a single number is saved (the same key as the old version). It returns to 0 if you clear site data. |
| Spellcheck and autofill | Turned off | The text box turns off browser spellcheck, autofill and writing suggestions, and marks itself as off-limits for extensions such as Grammarly and LanguageTool. Not every extension respects that, so no page can block them all. |
The screen itself, though, can't be protected. On a shared computer at work, school or a library, the person next to you may see it, and on some phones the keyboard app learns from what you type. Write sensitive things on a device only you use.
When it helps less
- When you keep replaying the same scene and writing harder: if the anger grows as you write, stop. Expressions that raise arousal did not reduce anger. If the weight went up after tossing, shifting your attention with breathing or a walk is the better move.
- When you're polishing a message to send: a message written in anger is easy to regret once it's sent. Toss what you wrote here and write what you actually want to send after you've calmed down.
- When it needs to be a record: if it's harassment or abuse you may need for a report or for counselling, don't write it here. Keep the date and details somewhere safe instead. A paper tossed here can't be recovered.
- When you're afraid of tossing by accident: Enter starts a new line, and tossing only happens with the button or Ctrl+Enter. The old version tossed on Enter alone, which made it easy to lose a long note, so this was changed.
Limits and cautions
- This tool is not therapy or counselling, and it does not diagnose depression, anxiety or anger problems.
- The study behind it is a small experiment in Japan (50 and 48 people), and it measured anger right after the experiment. Lasting effects, or effects on other feelings, haven't been tested.
- The study used real paper and did not test tossing on a screen.
- The 0 to 10 weight is a scale you set yourself. It is not the same score as the anger scale used in the study.
- The crisis phrase check looks for only a few expressions and misses many. If you feel unsafe, contact one of the numbers below right away, whether or not you use this tool.
When you need help
If the same thoughts keep coming back after you write and toss, or if sleep, eating and daily life are falling apart, please don't carry it alone.

Frequently asked questions
Is what I write saved or sent to a server?
No. Your text stays on this screen in your browser, and when you toss it the text box is replaced with a new one, which also clears the undo (Ctrl+Z) history. No request is sent to a server when you toss. The only thing kept in this browser is a single number that counts the papers you've tossed.
Does writing it down and tossing it really reduce anger?
In a 2024 Nagoya University experiment, people who wrote about what angered them and then crumpled the paper into a trash can (50 people) or put it in a shredder (48 people) saw their anger fall back to its level before the insult, while people who kept the paper stayed higher. It was done with real paper, though, so it hasn't been shown that the same thing happens on a screen.
What's the difference between crumpling and shredding?
They're the two methods from the study: experiment 1 used a trash can and experiment 2 a shredder, and anger fell in both. In the tool only the animation and the bin differ, so pick whichever suits your mood.
Do I have to pick a feeling name?
No, you can toss without picking one. There's research (Lieberman et al. 2007) showing that putting a name on a feeling reduced amygdala activity to upsetting pictures, so you can choose up to three. The names stay only in this tab's list.
What is the weight bar used for?
You rate how heavy it feels from 0 to 10 before and after tossing, and the tool shows the two side by side. For example, a 7 followed by a 4 reads "It's 3 lighter." It's a scale you set yourself, so it isn't the same as the anger score in the study, and it isn't saved.
Does pressing Enter toss the paper?
No. Enter starts a new line, and tossing only happens with the button or Ctrl+Enter (⌘+Enter on a Mac). The old version tossed on Enter alone, which made it easy to lose a long note by accident, so it was changed.
How do I clear the count of papers tossed?
The count is kept as a single number in this browser's storage. Clear roberin.com's site data in your browser settings and it returns to 0. In a private window it disappears when you close the window.
Does "emotional dumping" mean a person?
Often, yes. It usually describes one person unloading complaints and anger on another without checking whether the listener has room for it. Writing it on paper and tossing it first lets you bring only what's left to a real conversation, which tends to be shorter and clearer.
If I keep feeling heavy, is this tool enough?
This tool is a place to set something down for a moment. It isn't therapy or counselling. If you're thinking about suicide, call or contact 988 (Suicide & Crisis Lifeline) in the US, or Samaritans free on 116 123 in the UK and Ireland. If you're in immediate danger, call 911 (US) or 999 (UK).
