The audio opens with the show name, episode title and narration disclosure, then reads the chapter below. Spoken source names link to the references in this transcript. It closes by inviting corrections and noting that every depth level is needed.
Two questions about every gift
Most ways of judging a gift ask what it does. Charitology also asks where it acts: on the problem as it shows up in someone’s life today, or further upstream, on what keeps producing the problem. That is the distinction between symptoms and sources, and the depth scale turns it into five levels that anyone can use. The full scale is in the Method.
The five levels
0. Relief meets the need today. Its test question: is someone fed, sheltered or treated right now? A meal at a food bank, emergency surgery and a disaster shelter are relief.
1. Repair restores what was lost. Is someone back to where they were before the harm? Rebuilding a home, rehabilitation after an injury and a new job after a layoff are repair.
2. Prevention stops the harm happening to these people. Will these people avoid the harm altogether? Bed nets, vaccines and clean water for a village are prevention. In the trials pooled by a 2018 Cochrane review, insecticide-treated nets cut child deaths from all causes by about 17 percent.
3. Structure changes the rules that produce the harm. Did a law, institution, market or norm change so that the harm stops being produced? A lead-paint ban, a new public health system and a corporate standard are structure.
4. Source changes what feeds many problems at once. Did something upstream of a whole family of problems change? The story a society tells itself, how people coordinate and what a culture rewards are sources.
An old idea
The intuition behind the scale is old. Maimonides set out eight levels of giving in his code of Jewish law, the Mishneh Torah. The highest strengthens a person before they fall, with a gift, a loan, a partnership or work, so that they never need to depend on others. It is prevention placed at the top of a ladder of charity. Charitology’s scale borrows the direction of that ladder but not its ranking. See the entry on tzedakah in the Giving Traditions Library.
Depth describes. It never grades.
This is the rule that matters most. Every level is needed. A hungry person needs food tonight; a future promise cannot substitute for that help. A source-level change may take a generation, and it may fail. A world that funded only source work would leave people to suffer while it waited.
So the scale is not a ranking of virtue, and no charity is better for sitting higher on it. It is a description, like a map’s scale or a thermometer. Its job is to let a giver see what they are paying for, and to let the field ask the question that no single gift can answer: is the mix right? A healthy system funds all five levels on purpose.
The top of the scale
Level 4 comes from Humanity’s Checklist, which argues that world problems grow from six sources inside humanity’s collective life: the story we tell ourselves, how we coordinate, what we can picture of the future, what our feeds reward, what we admire and who gets to build. It pairs each source with a beachhead: one focused project that wins a foothold on that source. Its claim is that fixing a source stops it feeding the problems below and starts it feeding the cure.
Charitology adopts the six as the top of its scale and treats the larger claim as a hypothesis to test. It is the kind of claim that is easy to state and hard to measure, which is exactly why it needs testing.
When it works
Source-level results do happen. The campaign against smallpox ended a deadly disease for good. On May 8, 1980, the World Health Assembly accepted the World Health Organization’s finding that smallpox had been eradicated. Smallpox remains the only human disease declared eradicated worldwide. Eradication does not mean all spending stops: research and preparedness continue. The Record’s source-level classification is a Charitology hypothesis, and readers can challenge whether eliminating one disease fits a level defined around many problems. See the case study.
How to place real work
Real work rarely sits neatly on one rung. Four habits help.
- Classify the activity, not the cause. Every cause has work at every depth. Homelessness has shelters (relief), rehousing (repair), eviction prevention (prevention) and zoning reform (structure).
- Follow the money. One organization often works at several levels. Describe what each activity does, weighted by what it spends, not what the mission statement says.
- Name the chain. Deeper work depends on a longer theory of change. Write it down, and the level of the final goal usually becomes clear.
- Say when it is hard to call. If two careful people place the same work at different levels, record both. How often independent coders agree is itself a finding about the scale.
What this project has not established
Charitology’s founding hypothesis is the Symptom Trap: that the charity system as a whole is weighted toward the bottom of the scale, because relief is visible, quick and easy to credit, while work on sources is slow, shared and hard to measure. Charitology has not established the current mix or produced a public global dataset on this scale.
Checking is Open Problem 1, the Depth Census. A census describes the mix; deciding whether it is balanced also requires an explicit standard tied to the goals being considered. Evidence against the Symptom Trap should change or remove it. Measuring the effect of source-level work, so that it can compete fairly for money, is Open Problem 3, Measuring the Source. Until both are answered, every depth classification Charitology publishes is a description labeled as a hypothesis and open to challenge.
