No. The claim that 70 percent of wealth transfers fail traces to one 2003 book, and when family wealth psychologist James Grubman audited it in 2022 he found that the study everyone assumes exists does not exist. Nobody has ever tracked a representative cohort of wealthy families across three generations and counted the ruined ones.
The figure appears in Preparing Heirs by Roy Williams and Vic Preisser, who claimed research on 3,250 families showed 70 percent of transfers failed. The corpus audit The 70% Myth follows Grubman's citation trail to three findings. First, the 70 percent was inherited upside down: it is the arithmetic inverse of John Ward's 1987 finding that about 30 percent of some 200 Illinois manufacturing firms survived into the second generation, a regional study that also counted a profitable sale or merger as a failure. Second, the "3,250 families" evaporates on inspection: roughly 750 questionnaires went out at the authors' own seminars and only 177 complete responses came back, gathering opinions rather than measured outcomes. Third, the supporting citations attributed to MIT and The Economist do not contain the finding.
The number survives anyway because it confirms an ancient proverb, converts prospects for whoever quotes it, and launders itself through citation until it appears as "studies show" with no study attached. Shirtsleeves Is a Proverb, Not a Law adds the other half of the case: Gregory Clark's long-run surname data shows family status persisting for 10 to 15 generations across multiple countries, which is the opposite of a three-generation wipeout.
The misunderstanding is concluding that because the statistic is fake, the concern is fake. The corpus handles contested numbers consistently: demand the source, the sample, and the definition of failure, then salvage whatever survives the audit. Here, something does survive. When Williams and Preisser asked respondents why transfers go wrong, about 60 percent of failures were attributed to breakdowns of communication and trust, about 25 percent to unprepared heirs, and only around 15 percent to everything technical combined: tax, legal structure, and investment mistakes. The precise percentages deserve the same skepticism as the headline, since they come from the same 177 opinions. But the ranking keeps showing up in practitioner experience, in the Harvard Business Review's reanalysis of family business survival, and in the same Grubman paper that demolished the headline stat. Relational failure dwarfs technical failure. The main predator is silence, not the tax code.
Most families spend five or six figures on the 15 percent problem and zero hours on the 60 percent problem.
Schedule one family money conversation this week. Ninety minutes, topic announced in advance, no net worth disclosure required in round one. Start with history and intent: where the money came from and what it is for. Put the second conversation on the calendar before anyone leaves the room. A tense ninety minutes now is the cheap version of the estate dispute later.
