Frequently Asked Questions

All insurance has negative EV?
Yes — by design. Insurers must collect more than they pay out (operating costs + profit). Average buyer loses money. You buy insurance for tail-risk protection, not investment.
When is insurance smart anyway?
When the loss would be catastrophic (>10% of net worth) and you can't self-insure. Mandatory: car liability, health (in many countries), home if mortgaged.
Examples of bad insurance EV?
Extended warranties (often 50% loaded), phone insurance, dental for healthy adults, identity theft, pet insurance for old pets.
