Warren Buffett has spent more of his life reading annual reports than perhaps anyone else alive. It is the unglamorous core of how he works: hundreds of pages of corporate disclosure, year after year, decade after decade, read closely enough that whole industries live in his head. And inside that routine sits a rule he has stated in public. When he reaches a footnote he cannot understand, he does not conclude that the writer is more sophisticated than he is. He concludes the opposite. "If it is written so you can't understand it, I'm very suspicious," he said, in a line Scott West and Mitch Anthony preserved in their 2000 manual for financial advisors, Storyselling for Financial Advisors. "I won't invest in a company if I can't understand the footnote, because I know they don't want me to understand it."
Hold that inversion still for a moment, because it runs against everything the money world trains us to feel. The man who understands financial statements better than almost any reader on earth treats difficulty as a warning light. Not as evidence of depth. Not as a sign that the writer operates on a higher plane. As a signal that something is being kept from him. And if the best-equipped reader in the world responds to jargon with suspicion, consider what a wife, a son, a mother, or a brother feels when the family's money is explained to them in words they cannot follow.
That feeling, multiplied across a household and repeated over years, is where handovers quietly fail. So this article argues one idea the whole way through: a legacy that cannot be explained plainly cannot be handed on. Simplicity is not dumbing-down. It is the discipline that makes transmission possible, and the person in the family who does the work of saying things plainly is doing stewardship of the most literal kind.
The two books behind this article should not agree about much, which is precisely why their agreement matters.
Storyselling for Financial Advisors is a sales manual. West and Anthony wrote it in 2000 for American brokers who wanted to close more business, and it carries the fingerprints of its trade: scripts, client psychology, chapters organized around markets to win. Its promise to the advisor is blunt commerce: "Make the complex simple and understandable and you will never lack for clients." The working test the book puts under that promise is the one this article is named for. Before you present an idea, ask whether Grandma would get it. If she would not, the idea is not ready, whatever the presenter's credentials say.
Fifteen years later and from the opposite end of the industry, Jean Brunel published Goals-Based Wealth Management. Brunel is about as far from a sales trainer as the profession offers: the founding editor of the Journal of Wealth Management, a veteran of nearly four decades managing money for some of the wealthiest families in the world, and his book is dense with machinery meant for licensed professionals. It is, in most of its pages, exactly the kind of book a family should never be handed. Yet when Brunel opens his argument, the foundation he lays under all of that machinery is a single plain sentence: "clients do not ask advisors how to make a watch; they ask them what time it is."
Read those two claims side by side. A street-level closer and an institutional theorist, writing fifteen years apart for entirely different audiences, arrive independently at the same rule: the person across the table is not asking for your complexity. They are asking for the time. When two ends of an industry that agree on almost nothing converge on one sentence, that sentence is probably not a style preference. It is structural. Something about how human beings receive and trust information forces it into view wherever money has to pass from a person who understands it to a person who must live with it.
Both books aim the rule at professionals winning clients. What follows from here is our reading of it, and it is larger than the industry that discovered it. Every family that intends to hand anything on runs the same conversation the advisor runs, with higher stakes and no commission: one person holds the understanding, another person needs it, and the words in between either carry it across or drop it.
Start with what plain speech costs the speaker, because that cost is the reason it is rare.
To say a thing simply, you must know which parts of it carry the weight. A person who half-understands an idea cannot compress it. They can only repeat the vocabulary it arrived in, because the vocabulary is all they actually hold. The specialist words are doing the understanding on their behalf. Ask them to put it another way and they cannot, not because the idea is deep but because their grip on it is shallow. West and Anthony make the positive case with a lineage they are unembarrassed to invoke: the greatest teachers in history did not talk over their audiences, and their simplicity was not a concession. Jesus taught in parables. Franklin compressed a working philosophy of money into Poor Richard's lines that farmers repeated to their children. Einstein, asked about relativity, reached for a hot stove rather than a field equation. The book's point is not that these figures simplified because their listeners were limited. It is that they could simplify because their understanding was complete.
That flips the grandmother test into something more uncomfortable than it first appears. It is not a test of the grandmother. It is a test of you. When your explanation of the family's savings plan, or the reason the land must not be sold piecemeal, or how the school fees are secured, cannot survive translation into plain words, the failure is not in the audience's schooling. It is in the speaker's mastery. The elder or advisor who cannot say it plainly has not yet understood it well enough to hand it over. They may be able to operate it. Operating and understanding are different depths, and transmission draws on the deeper one.
This is also why the plain sentence is almost always the last draft, not the first. Anyone who has tried to explain a pension, a land title, or an insurance policy to a family member knows the sequence: the first attempt comes out in the vocabulary of the document, the second attempt in half-translated fragments, and only after real effort does the version arrive that a listener can hold and repeat. That effort is not a favor to the slow. It is the work of finishing your own understanding in public. Families that never do this work do not have a shared plan. They have one member's private plan, plus an audience.
Now take Buffett's footnote rule seriously as a statement about trust, because that is what it is.
His logic runs: writing can be made clear, so when it is not clear, the obscurity is a choice, and the most likely motive for that choice is concealment. West and Anthony build the advisory version of the same case. The advisor who hides behind jargon to look impressive, they argue, loses the very relationship the jargon was supposed to win, while the advisor who makes a hard idea plain is trusted with more, because plain speech reads as having nothing to hide. In their telling, the client sitting through an incomprehensible presentation is not thinking "this person is brilliant." The client is thinking some version of what Buffett thinks about the footnote.
Inside a family, the same mechanics run hotter, because the listener cannot walk away to another advisor. A spouse who is told "you would not understand it, it is complicated" hears distance, whatever was intended. An adult child who asks why the family does what it does with money, and receives a fog of borrowed seminar language, learns two things: that the subject is not really open to them, and that asking again is a small humiliation. Neither lesson appears anywhere in the speaker's intent. Both are transmitted perfectly. Jargon inside a household is rarely deployed to deceive. It is deployed to protect status, or to avoid the labor of translation, and it collects its tax anyway: every unexplained term is a small withdrawal from the account of trust that a handover will one day need to draw on.
One caution belongs here, and it comes from the source itself. Storyselling is a persuasion manual, and in places it is frank that its communication craft can be used to steer a listener toward a conclusion the speaker has already chosen. That half of the book stays on the shelf. In a family, clarity used to steer is manipulation wearing a warm face. The craft worth taking is the opposite discipline: make the idea so plain that the listener can genuinely weigh it, disagree with it, and improve it. Plain speech that survives disagreement is transmission. Plain speech engineered to end disagreement is just a softer fog.
Brunel's watch sentence deserves a closer look, because the man who wrote it had every credential required to answer in gears.
What makes his testimony valuable is what he does when he actually sits with families. By his own account, he deliberately abandons the industry's vocabulary at the door. In place of the standard talk of objectives and risk tolerance, he asks families to sort what they want into four ordinary words: "For goals, I invite clients to discuss needs, wants, wishes, and dreams." For the other side of the ledger: "For risk issues, I suggest that they talk in terms of nightmares, fears, worries, and concerns."
Notice what those plain words accomplish that the jargon never could. They rank themselves. No one has to be taught that a need outranks a wish, or that a nightmare demands more protection than a concern. The urgency is carried inside the everyday meaning of the words, so the moment a family speaks its money life in them, the priorities surface on their own. Technical vocabulary does the reverse: it flattens everything into the same gray register, where school fees and a speculative side venture are both "objectives," and the family's actual hierarchy of care disappears into terminology. Brunel's plain words are not a simplification of the analysis. They are the analysis, done in language the whole household already owns.
He adds a second warning that completes the picture: false precision is jargon wearing numbers. His own process, he insists, "is more systematic than quantitative," because no one truly feels the difference between one finely stated probability and another, and pretending otherwise dresses uncertainty up as knowledge. A decimal point can intimidate a listener as effectively as a Latin phrase. The honest plain version of most financial statements a family needs to hear sounds like: this is very likely, this is possible, this we cannot know yet. Anything more precise than the speaker's actual knowledge is one more footnote written not to be understood.
So when the people in your household ask about the money, hear the question Brunel heard. They are not asking you to open the watch. They are asking what time it is, and whether they can rely on the answer. The temptation of the person who has learned the watch's insides, often at real personal cost, is to answer with gears, partly from pride and partly because gears are easier to recite than time is to tell. Telling the time takes more understanding, not less.
Neither West and Anthony nor Brunel wrote a word about Africa, and nothing in this section should be attributed to them. What follows is our translation, from the world their books describe into the one most of our readers live in. In that world, the grandmother test stops being a figure of speech.
Across much of the continent, a family's financial life is written in one language and lived in another. The land title, the bank forms, the insurance policy, and the loan agreement are in English or French, drafted in legal register on top of that. The family's actual deliberation happens in Luganda, Swahili, Runyankole, Lingala, Yoruba, Amharic, or a dozen tongues per country, around tables where schooling ranges from doctorate to none inside a single generation. Whoever in the family learned finance learned it in a borrowed vocabulary, usually far from home. Which means an African handover is a double translation: from expert language to plain language, and from the borrowed tongue to the one the family thinks in. A plan that has not made both crossings has not arrived.
This is where the wide obligations of the extended family sharpen the rule instead of complicating it. Where support flows outward to cousins, siblings, and elders as duty, the circle of people who must understand the plan is wider than the nuclear household, and the range of schooling inside that circle is wider still. A plan that only the most educated member can restate is not the family's plan. It is that member's plan, running on everyone else's patience, and patience is not a transmission channel. The same holds for the tools. Mobile money moved the whole household's finances onto a screen; a SACCO's share statement, a herd, a plot under customary tenure, and a season's stock in a market stall are all parts of one position that someone must be able to describe in one plain telling. Oral retelling is not the primitive version of financial literacy here. It is the infrastructure. For generations, what a family knew survived exactly as far as it could be retold, and that has not changed because the assets now have paperwork.
So run the test that our whole tradition has always run. Take the reason behind any family money decision and ask: could this be retold at a family gathering, accurately, by someone other than you, in the language the family actually speaks, without you in the room to correct it? If yes, it is on its way to being legacy. If no, it is still private property, whatever the paperwork says.
And notice, finally, who was right all along. The grandmother whose eyes narrow at a confident young relative's stream of English financial terms is not displaying ignorance. She is applying, without a portfolio, precisely the rule Buffett applies to footnotes: what refuses to be understood has a reason for refusing. Her suspicion is not an obstacle to the family's financial progress. It is quality control, and the correct response to it is not a slower repetition of the same jargon. It is better understanding, spoken plainly, until the narrowed eyes relax because the thing finally makes sense.
Put the pieces together and one practical conclusion follows, and it inverts how most literate families treat their documents.
The instinct is to treat the formal version as the real one: the title, the policy, the will, the agreement, with the plain spoken explanation as a courtesy summary for those who cannot manage the original. Documents matter enormously, and nothing here argues otherwise. But for transmission, the hierarchy runs the other way. The plain version is the operative one, because it is the only version that can circulate through the family without an interpreter, survive retelling, and shape behavior between the rare occasions when a document is actually read. The formal papers are the skeleton. The plain telling is the bloodstream. A family with perfect documents and no shared plain understanding has a legacy that exists only at the level of paperwork, waiting to become a dispute among people who were never told, in words they could hold, what it all meant.
That is the standard worth adopting as a household rule: nothing about the family's money is considered settled until it exists in a version the least-schooled adult in the family can repeat. Not agreed to. Repeat.
Here is the concrete piece of work this article asks of you, and one month is enough for it.
Choose one load-bearing piece of your family's money logic that currently lives only in your head or in a document. Why the savings are kept in separate pots instead of one pile. Why the land is held and not sold. How the school fees are protected before anything else is funded. What the family business owes the family, and what it does not. One item, not ten.
Now put it into the Wisdom Library in LegacyPot, in your own voice, in the language your family actually thinks in, under one test: say it so your grandmother gets it. No borrowed seminar terms, no undefined English where a home word exists, no precision you do not actually possess. Then run the proof, because plain is not self-certifying. Share the recording with two listeners at the extremes: the eldest person who will engage, and the youngest adult or near-adult who should one day carry this. Ask each to tell it back in their own words. Every place their retelling wobbles is not their failure; it is a sentence of yours that has not finished being understood. Revise and re-record until the idea comes back to you intact from both of them.
What you will have at the end is small and unglamorous: one idea, a few minutes long, that your family can now carry without you in the room. That is what transmission actually looks like at the level of a single week's work. The footnote written to be understood. The time, told plainly, by someone who finally knows the watch well enough to stop talking about the gears.
