What makes gambling wrong but insurance right? (2017)

Conceptual Difference: Risk, Variance, and Utility

• Many comments frame gambling and insurance as opposites regarding variance:
  • Insurance: you pay a (usually) negative expected-value premium to reduce downside variance and avoid catastrophic loss.
  • Gambling: you pay a (usually) negative expected-value stake to increase variance, hoping for a life-changing upside.
• Several note that this makes sense under non-linear “utility of money”: a big loss hurts more than a comparable gain helps, so paying to cap losses can increase expected utility even if it reduces expected dollars.

Are Insurance and Gambling the Same Thing?

• One camp: they are fundamentally the same “risk swap”:
  • Both are zero- or negative-sum for participants once house/insurer profit is included.
  • Buying insurance is “betting that something bad will happen”; selling insurance resembles running a casino.
  • Derivatives, shorting, and custom policies blur lines between hedging and speculation.
• Opposing camp: they are operationally and morally distinct:
  • In gambling you accept risk; in insurance you transfer it.
  • Insurance typically requires “insurable interest” and caps payouts to actual loss, limiting speculative profit.
  • You want to “win” a bet; you generally do not want the event that triggers an insurance payout.

Health Insurance vs Classic Insurance

• Multiple comments argue that US-style “health insurance” is mostly not true insurance:
  • It covers predictable, routine consumption and chronic care, not just rare, catastrophic events.
  • This creates third-party-payer distortions, complex billing (deductibles, co-pays, co-insurance), and incentives for risk selection.
• Others counter that catastrophic medical events are insurable and that social needs justify collective coverage despite these issues.

Practical Guidance: When Insurance Is Worth It

• Broad consensus:
  • Insure large, low-probability losses you cannot easily absorb (home, liability, catastrophic health, major auto accidents).
  • Self-insure small, frequent, or easily replaced items (phones, extended product warranties, bikes for some people).
• Wealth and risk tolerance matter: the wealthier or more diversified you are, the more you can self-insure.

Ethics, Regulation, and Harm

• Gambling is often criticized for addiction and preying on the vulnerable; insurance for claim denial, fine print, and guaranteed profit.
• Some suggest public or mutual insurance as an alternative; others argue competition and regulation are key to keeping for-profit insurers in check.
• Several note that not buying insurance is itself a gamble; society mandates some coverages (auto liability, mortgages) to protect third parties and reduce extreme hardship.
