The Principle Test

Five questions short enough to fit on one line of a notes app.

Last reviewed: 26 September 2026 · Next review due: 26 September 2027

Most ethical failures are not decisions to do wrong. They are decisions taken under pressure by people telling themselves a story in which the compromise sounds reasonable. The test is designed to be run before that story starts.

Five questions, run before the excuses begin: could I defend this in daylight in my own name, what compounds if it happens a thousand times, would I accept it from the other side, will I be proud of it in five years, and what does this decision make me. Short enough for one line of a notes app, which is the design constraint.

The answer, in one line

Public defence: could I defend this decision in daylight, in my own name? Scale: if this act were repeated a thousand times, what harm would compound?

The pressure it is built for#

When pressure builds, clarity fades. Deadlines shorten, numbers rise, and people start telling themselves stories in which the compromise sounds reasonable. Every professional knows the rhythm: fix it next quarter, raise the concern after the launch, make it right once the board has approved. Drift starts in the background, and by the time anybody names it the reasoning has already adjusted itself to fit.

The antidote is a test that exists before the excuses, and that is fixed enough not to be reworded by the situation. Most ethical failures are not decisions to do wrong. They are decisions taken quickly by people who had no question to put in the way.

The five questions#

  1. Public defence. Could I defend this decision in daylight, in my own name? It stops rationalisation, because the reasons that work privately tend to sound different said aloud with your name attached.
  2. Scale. If this act were repeated a thousand times, what harm would compound? It reveals the damage that is invisible in a single case, which is where most systemic harm lives and where automated systems operate by default.
  3. Reversal. Would I accept this if I were on the receiving end? It restores the perspective of the person affected, and becomes hardest to answer honestly when you are certain they will never find out.
  4. Time. Will I be proud of this in five years, when the urgency has faded? It replaces expedience with distance, and urgency is the variable it removes.
  5. Identity. What does this decision make me? It moves the question from the act to the person performing it, which is the only version some people will actually answer.

Why five rather than one#

Because each catches a different failure, and any one of them alone can be satisfied by a decision the others would refuse. A decision can be publicly defensible and harmful at scale. It can be acceptable at scale and something you would not accept yourself. The test is cheap enough to run all five, and running one is how it gets performed rather than used.

The scale question and machines#

The second question has changed in force. A decision made once by a person is now often a decision encoded into a system that will make it several million times without anybody revisiting it. The harm that compounds is no longer hypothetical: it is the default behaviour of the thing being built, and the person who wrote the rule may never see a single instance of it. That is the connection between this test and the fourth receipt, which asks who bears the consequence including those who never enter the system as data.

What this has not been shown to do#

The test has not been trialled. Nobody has compared decisions made with it against decisions made without it, and the questions resemble long-standing devices in applied ethics, including publicity tests and reversibility tests, for which no first use is claimed. The claim here is to this set of five, in this order, sized to be run in the moment rather than in a seminar. A person determined to reach a particular answer can pass all five, and the test does not pretend otherwise.

Questions answered on this page

What are the five questions?

Public defence: could I defend this decision in daylight, in my own name? Scale: if this act were repeated a thousand times, what harm would compound? Reversal: would I accept this if I were on the receiving end? Time: will I be proud of this in five years, when the urgency has faded? Identity: what does this decision make me?

Why does it need to be run early?

Because under pressure people construct reasons that make compromise sound reasonable: fix it next quarter, raise the concern after the launch, make it right once the board approves. The test is an attempt to get a fixed question in before the reasoning starts adjusting itself.

What does each question do?

The public test stops rationalisation. The scale test reveals damage invisible in a single case. The reversal test restores the perspective of the person affected. The time test replaces expedience with distance. The identity test moves the question from the act to the person performing it.
