View the Alan Turing ethical assessment profile
This assessment does not reduce the subject to one moral ranking. Each dimension is scored separately from −100 to +100 and must be read with its evidence and uncertainty.
Scorecard status: Recalculated under multidimensional system
The assessment covers Turing's foundational work in computation, wartime codebreaking, contribution to shortening the Second World War and the limits created by secrecy and military application.
The score evaluates documented public conduct during the stated period. It does not measure inherent human worth, does not constitute a legal verdict and remains open to correction when stronger evidence becomes available.
Turing's record is strongly positive. His work combined exceptional intellectual benefit with direct service against a genocidal regime. The principal cautions concern collective attribution and the dual-use nature of computing and cryptography.
This assessment presents six separate ethical dimensions rather than one overall moral score. Each result must be read with its evidence, plausible range, confidence, disputes, exclusions, severe-harm findings and sources.
| Domain | Score | Intensity | Confidence |
|---|---|---|---|
| Consequences | +90.0 | 90.0 | B — high |

| Care | +60.0 | 60.0 | B — high |
| Justice | +55.0 | 55.0 | B — high |
| Wisdom and judgment | +75.0 | 75.0 | B — high |
| Baseline ethics | +60.0 | 60.0 | B — high |
| Positive pole | Negative pole | Score | Intensity | Confidence | Reasoning |
|---|---|---|---|---|---|
| Human dignity | Dehumanisation | +60.0 | 60.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Human dignity and Dehumanisation. |
| Care | Neglect | +60.0 | 60.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Care and Neglect. |
| Benefit | Harm | +90.0 | 90.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Benefit and Harm. |
| Benevolent intention | Malicious intention | +75.0 | 75.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Benevolent intention and Malicious intention. |
| Justice | Injustice | +55.0 | 55.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Justice and Injustice. |
| Respect for rights | Violation of rights | +45.0 | 45.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Respect for rights and Violation of rights. |
| Integrity | Corruption | +80.0 | 80.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Integrity and Corruption. |
| Prudence | Recklessness | +75.0 | 75.0 | B — high | Calculated from 1 reviewed evidence item(s) concerning Prudence and Recklessness. |
The dominant evidence concerns foundational computing theory and codebreaking that materially assisted the defeat of Nazi Germany and likely reduced wartime death.
The score is moderated by the military and surveillance uses inherent in cryptanalysis and by uncertainty over individual attribution within a large secret intelligence organisation.
TUR-C1
His theoretical and practical work helped establish computer science and materially assisted Allied codebreaking.
TUR-R1
His wartime work supported resistance to a regime engaged in aggressive war and systematic persecution.
TUR-V1
His scientific work was original, testable and directed toward difficult practical and theoretical problems.
TUR-I1
The central purposes were knowledge and defence against wartime aggression rather than domination or personal gain.
TUR-CA1
His contribution aided military decisions that protected civilians and service personnel, though the work was indirect and secret.
TUR-J1
His work supported the defeat of a regime responsible for profound injustice, while he exercised little control over wider Allied policy.
TUR-W1
He combined mathematical insight with practical engineering and adapted methods to urgent intelligence needs.
TUR-B1
His work contributed to ending a war and regime that treated millions as expendable, though later computing had dual-use consequences beyond his control.
Claims about the exact number of lives saved or years by which the war was shortened are estimates. The assessment credits a major contribution without assigning unsupported numerical effects.
The British state's criminal prosecution and mistreatment of Turing are harms done to him, not ethical failures by him.
