This is the complete rulebook and the exact math behind lifescored.com.","privacy":"Compute scores on your OWN side. This contains only the rules — no personal inputs are ever sent to lifescored.com, by the website or by the MCP/API. The whole point falls apart the moment the thing scoring you has something to sell you.","methodology":"life. scored. rebuilds the scores that real systems already run on you — credit bureaus, actuarial life tables, lenders, audit-study research — in the open.\n\nHow scoring works:\n- Every rule is a pure function from your inputs to a position (0..1, where 1.0 = full marks), with declared bounds and an editorial weight.\n- points = round(clamp(position, bounds) × weight). The composite is the sum over enabled rules. The breakdown is the point; the composite is the least useful number.\n- Weights are stated as multiples of the income baseline (1.0× = weight 10) and are tunable — every one shows its own justification.\n- Rules are split into \"your starting point\" (luck of where/to whom you were born) and \"your moves\" (what you influence).\n\nTwo principles govern every rule:\n- Constrained-subtractive: a rule may score negative only where the cited system itself subtracts (FICO delinquency, license points, underwater net worth, eviction), and never more than it can add unless the system does exactly that.\n- Uncapped wealth: income and net worth grow as the square root of your multiple of the median, with no upper limit, matching how wealth actually distributes.\n\nDeliberately left out:\n- Protected characteristics (race, religion, etc.) and identity/\"otherness\": real, and they absolutely change how others score you, but we won't hand anyone a number that docks them for who they are — that's the machinery this exists to expose. They stay an unscored asterisk.\n- Pure luck (a recession at graduation, illness, timing): real but unmeasurable honestly, so also an unscored asterisk.\n\nPrivacy: inputs never leave the user's device.
