What makes gambling wrong but insurance right? (2017)
Gambling and insurance both involve paying now for uncertain future outcomes, but many argue they occupy opposite ends of a risk spectrum: gambling increases an individual’s exposure to volatility, while insurance reduces it by spreading catastrophic losses across many people. Commenters debate whether insurance is just “respectable gambling” or a distinct tool for risk transfer, bringing in concepts like expected value, utility of money, addiction, regulation, and the special case of health insurance, which often functions more like prepayment for care than true coverage for rare events. Overall, the exchange highlights how intent, structure, and societal impact shape the moral and practical line people draw between betting for gain and paying to hedge against loss.
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.
