Don’t fall into the n=1 trap

Opinion

Just as a leader’s personal wealth trajectory offers a poor lens through which to judge national economic well-being, a marketer’s personal response offers a poor proxy for market response at scale, writes the MD of Media Futures Market.

In last month’s State of the Union address, Donald Trump fell into the n=1 trap. It is the easiest misstep for marketers and leaders of any kind to make.

According to Forbes, his personal wealth grew by over $3bn in 2025. Meanwhile, the average American is experiencing a different reality, with sustained inflation in key areas such as housing, healthcare, and groceries.

Trump spoke about the strength of the economy from a position of visible personal prosperity. By most credible financial estimates, he is now wealthier than at any point in his life, driven largely by asset valuations, brand-linked equity, and ventures tied directly to his personal platform. From that vantage point, the economic climate can quite plausibly appear robust. Capital has appreciated. Assets have grown. Personal wealth has expanded materially.

The problem I want to highlight (there are others I won’t address here) is not that his experience is fabricated. It is that it is statistically unrepresentative.

I’m getting richer, so I’m sure everyone must be doing well

This uniquely accumulative president inhabits an economic reality that bears little resemblance to that of the median household managing medical debt and day-to-day purchasing power. From a macroeconomic standpoint, distribution is as important as direction, and the experience of the extreme top of the wealth curve tells us remarkably little about the centre of it.

Although Trump never outright says, “I’m getting richer, so I’m sure everyone must be doing well”, the rhetoric implicitly treats personal financial ascent as corroborating evidence of national economic strength.

This is less an argument grounded in aggregate indicators (real wages, productivity, inflation-adjusted consumption, labour participation) and more a narrative rooted in lived experience.

His wealth has increased markedly; therefore, the economic environment must be favourable. It is coherent as a personal narrative, but weak as an analytical framework.

There is also a quieter form of attribution bias embedded in such claims. Complex economic outcomes are shaped by multi-year policy cycles, global capital flows, monetary conditions, and structural forces that extend far beyond any single administration. To map those outcomes onto the balance sheet of one unusually positioned individual is to substitute anecdote for distribution.

In methodological terms, it is an n=1 observation presented as a macro signal.

One individual becoming significantly richer, particularly one whose wealth mechanisms are tied to asset revaluation and ownership leverage, does not meaningfully indicate whether median living standards are improving.

Indeed, the insulation that accompanies extreme wealth often dampens exposure to precisely the pressures that define broader economic experience. Rising personal net worth can coexist comfortably with widespread cost-of-living strain. Both realities can be true simultaneously, which is precisely why singular vantage points are such poor diagnostic tools for system-level health.
