Short answer:
If for a week everyone on Earth could not lie and had to answer any question truthfully, social trust would spike but many harms would follow: privacy collapse, damaged relationships, political chaos, security risks, economic disruption, legal upheaval, and ethical dilemmas. Some benefits would include exposed corruption, accelerated problem-solving, and clearer personal and collective priorities.
Key effects (concise):
- Personal relationships: Many secrets, infidelities, resentments would surface, causing immediate pain and possible long-term realignments or reconciliations.
- Privacy and autonomy: Questions about personal thoughts, health, finances, genetic information, sexual orientation, etc., would become impossible to conceal—privacy rights would be devastated.
- Politics and governance: Hidden deals, motives, corruption, classified information would be revealed; short-term instability but potential long-term accountability.
- Security and law enforcement: Intelligence operations, undercover work, witness protection, and national-security secrecy would collapse; crime investigations might accelerate but also enable retaliation.
- Economy and markets: Insider trading, fraud, and misleading advertising would vanish, but supply chains and negotiations could be disrupted by forced disclosures.
- Medicine and science: Research fraud would be exposed; patient consent dynamics change if truthful disclosure is mandatory; beneficial truths (diagnoses, errors) could improve outcomes.
- Social order and morality: Many social norms rely on white lies and tact—removing them would increase blunt honesty but also cruelty; utilitarian trade-offs between truth and harm would become stark.
- Legal system: Perjury becomes impossible; prosecutions might benefit, but forced testimony could violate rights and international law.
- Cultural differences: Societies valuing harmony over blunt truth (e.g., some East Asian norms) would face sharper shocks than those valuing directness.
Duration and aftermath:
- Short week: Intense upheaval, many relationships and institutions tested but not necessarily destroyed.
- Aftereffects: Some truths lead to reform and cleansing (e.g., exposed corruption); others leave lasting trauma and new secrecy techniques (nonverbal evasion, refusal to ask questions, technology to avoid answering).
- Behavioral adaptation: People would develop strategies—avoidance, silence (if not compelled to answer every possible question), asking questions instead of answering, or using ambiguous phrasing before/after the effect ends.
Philosophical notes:
- Reveals tensions among truth, autonomy, privacy, and harm (Kantian duty to truth vs. Mill’s harm principle).
- Shows limits of truth as an unqualified good: truth can facilitate justice but also cause unnecessary suffering when not contextualized by prudence or consent.
