Ethical Scores of Modern World Leaders
A current comparison of active world leaders across six ethical dimensions, with scores, confidence grades and important limits on interpreting the ranking.
Truth By Reason
Ethical Assessments
Ethical Assessments examines the documented conduct and impact of people, governments, organisations, policies and events. It brings evidence, uncertainty and opposing ethical considerations into a reasoned public judgment.
Assessing conduct rather than reputation
Reputation, wealth, power, ideology and popularity do not determine an ethical assessment. The central questions are what the subject did, what effects followed, who was affected, what responsibilities existed and how reliable the available evidence is.
Positive and harmful conduct remain visible rather than being replaced by simple praise or condemnation. Assessments may cover particular periods and may be revised when stronger evidence becomes available.
These are reasoned ethical evaluations. They are not legal verdicts, declarations of absolute truth or measurements of a person’s inherent human worth.

Scoring explained
How Truth By Reason Calculates Ethical Scores
A transparent explanation of how evidence is assessed, how six ethical dimensions are scored and how the public overall result is calculated.
Introduction
What Is an Ethical Assessment?
A clear introduction to how Truth By Reason examines conduct, responsibility, consequences, evidence and uncertainty without reducing a person or institution to simple praise or condemnation.
Understanding the method
Ethical axes
Ethical Leadership: What Should Be Measured?
Ethical leadership requires more than popularity, competence or good intentions. This article identifies the conduct and consequences that should be measured.
Limitations and uncertainty
Is It Fair to Assign Historical People Ethical Scores?
Historical ethical assessment can be fair only when it accounts for context, evidence limitations, responsibility and standards that are applied consistently.
Interpreting ethical results
Interpreting results
Good Achievements by Morally Harmful Leaders
A reasoned examination of genuine achievements attributed to leaders whose overall ethical records remain harmful, and why recognition is not moral cancellation.
Interpreting results
Can a Person’s Good Actions Outweigh Severe Harm?
Positive achievements must be recognised, but they do not operate as moral credit that automatically cancels genocide, aggressive war, persecution or mass suffering.
Interpreting results
Can Morality Be Measured?
Ethical scores can organise evidence and make comparisons more transparent, but they do not turn morality into a physical quantity or eliminate moral disagreement.

Muhammad
Combined historical-and-traditional assessment. This assessment distinguishes broadly recoverable historical conduct from reports preserved in later Islamic biography and canonical hadith, whose historical reliability varies. Muhammad promoted charity, care for orphans, community solidarity, negotiated settlements and some limits on vengeance. He also became a religious, political, judicial and military ruler; led warfare; accepted slavery and concubinage; and maintained unequal rights based on sex and religious status. Traditional sources further associate him with execution and enslavement of defeated groups, marriage and consummation at an age incompatible with modern consent standards, death for apostasy and stoning.
