Overall ethical score
+10.43
Reasoned summary
Thatcher's record is ethically mixed and close to neutral. Some reforms addressed genuine economic failure, but the methods and distribution of costs showed insufficient care, equality and social repair.
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.
Most significant negative evidence
Negative evidence concerns severe concentrated harm to industrial communities, high unemployment, divisive policing and union policy, widening inequality and discriminatory legislation affecting LGBT people.
