This page asks a narrow question and answers it with 5 inputs: opponent’s emotional volatility, how clearly can you state your point in one sentence?, preparation / rehearsal level and audience present?. The output is one number, a rumination score. Edge cases dominates the arithmetic; the rest adjust around it.
Anything under 25 reads as the settled case; the top band, step away, begins where the pattern is consistent rather than occasional. The published weights are the whole model: edge cases at -1 and opp volatility at +0.9. They are shown in the table below rather than hidden, so you can disagree with a specific number instead of the result as a whole. The model is a weighted sum passed through a sigmoid, which is what keeps the result inside 0–100 no matter how extreme one input gets. Opp volatility and audience push the number up; clarity and prep pull it down.
The useful reading is the band, not the exact figure. Two results a few points apart describe the same situation; it is the 4 thresholds that carry the meaning. The more informative move is to change one input and watch how far the result travels. That sensitivity tells you which lever is real and which is noise, which is more actionable than any single reading. It is a model built on self-reported inputs, so it inherits whatever bias is in your own estimates, and it describes a pattern rather than predicting an outcome. Everything runs in your browser; nothing you enter is sent anywhere or stored.
The formula
w1·opp volatility- Opponent’s emotional volatility (weight +0.9)
w2·clarity- How clearly can you state your point in one sentence? (weight -0.9)
w3·prep- Preparation / rehearsal level (weight -0.9)
w4·audience- Audience present? — 0 = private, 10 = full room (weight +0.6)
w5·edge cases- Counter-arguments you have resolved (weight -1)
σ, μ- Sigmoid squash to 0–100, centered on typical values
How it works, step by step
- Rate each input honestly — the Rumination score is only as good as your self-assessment.
- Watch the live score and note which factor the result panel names as your strongest driver.
- Read your band below — each range comes with a concrete recommended next step.
- Change one input to simulate a change in behavior and see how much the score moves — that sensitivity is the real insight.
- Re-take the assessment after a few weeks; trends across readings mean far more than any single score.
Worked examples
A low-signal scenario
With every input set well below typical — the quiet version of this situation — the model returns 70, landing in the “Shaky ground” band. Conditions strongly favor you: solid preparation, manageable opposition, low situational pressure. Deliver briefly and let the structure work.
A high-signal scenario
Push the main drivers well above typical and the score rises to 21 — the “Composed” band. This engagement, in these conditions, mostly costs you. The healthiest move is often deferring, de-escalating, or accepting that being right quietly is free.
How to read your score
Frequently asked questions
How is the Rumination Score score calculated?
It combines your preparation quality (resolved counter-arguments matter far more than raw rehearsal volume) against opponent factors — defensiveness, volatility — and situational pressure like audience size. The formula and every weight are published on this page.
How do I stop replaying conversations in my head?
Past a threshold the model flags rumination: scheduled worry time, writing the argument out once, and deliberate closure rituals all outperform continued mental replay. If rumination is persistent and distressing, a therapist can help more than any calculator.
Does mental rehearsal actually help win arguments?
Up to a point. Anticipating genuine counter-arguments measurably improves persuasion; replaying your own best lines does not. The model deliberately rewards edge-case coverage and applies diminishing returns to repetition.
Why do I lose arguments I win in my head?
Because rehearsal simulates a cooperative opponent. Real opponents have defensive bias and emotional stakes — the two variables this calculator weighs most heavily against you.
What is the single best way to improve my score?
Compress your position into one clear sentence. Clarity is the highest-leverage input in the model: people rebut the weakest thing you say, so saying fewer, stronger things dominates saying more.
Is this scientifically validated?
The components draw on real persuasion and rumination research, but the composite score is an educational model, not a validated psychometric instrument. Treat it as structured reflection.
