The Ig Nobel Prizes, a humorous counterpart to the Nobel Prizes, celebrate research that “makes people laugh, then think.” This year, Saul Justin Newman, a senior research fellow at University College London, received the prize for his work challenging claims about extreme human longevity. Newman’s research reveals that many reported cases of people living past 105 are often inaccurate, raising significant questions about our understanding of aging.
This article delves into Newman’s findings, exploring the flawed data surrounding extreme longevity and its implications for everything from pension funds to healthcare planning. From bombed record halls to widespread pension fraud, the reality of human lifespan is far more complex than often presented.
Unmasking the Centenarians: A Closer Look at the Data
Newman’s interest in longevity began when he debunked several high-profile studies on extreme aging. His investigation into the lives of supercentenarians (those over 110) unearthed startling discrepancies. He found that approximately 80% of these individuals lack verifiable birth certificates. In the US, where over 500 people are purportedly over 110, only seven possess confirming birth certificates. Furthermore, death certificates are equally elusive, with only about 10% of these cases having documented proof of death.
The “Blue Zones,” regions famed for supposedly high rates of centenarians, are a prime example of this data problem. Okinawa, Japan, a designated Blue Zone, underwent a government review in 2010. Shockingly, 82% of the registered centenarians were discovered to be deceased. Similar discrepancies appear in other Blue Zones like Sardinia, Italy, and Ikaria, Greece, where life expectancy data reveals a far less remarkable picture than the popular narrative suggests. Newman’s research suggests that a significant percentage of centenarian claims in Greece are likely due to death underreporting or pension fraud.

The Root of the Problem: From War Records to Pension Fraud
The reasons for these data inaccuracies vary. In Okinawa, the destruction of records during World War II contributed to the problem. In Greece, widespread pension fraud has inflated the number of reported centenarians. Similarly, Italy has also grappled with issues of deceased pensioners continuing to receive benefits. Newman points out a correlation between regions with high reported centenarian rates and those with both a strong incentive for pension fraud and poor record-keeping. Tower Hamlets in England, for instance, boasts more supposed 105-year-olds than affluent areas but simultaneously suffers from low numbers of 90-year-olds and poor elderly care.
Even seemingly simple matters like age reporting are prone to errors. Data from sources like the UK Biobank reveal that individuals, even in middle age, frequently misreport their own age or the age at which they had children. This highlights the inherent challenges in relying solely on self-reported or poorly documented age information.
Rethinking Longevity: The Need for Accurate Measurement
The implications of inaccurate longevity data are far-reaching. These figures are used to project future lifespans, impacting pension calculations, healthcare resource allocation, and insurance premiums. With faulty data, these projections become unreliable, potentially leading to misallocation of trillions of dollars.
Newman advocates for a more scientific approach to age determination, involving physicists in developing objective measures of human age independent of documents. This would provide a more reliable foundation for understanding longevity and its associated factors.
Wealth and Longevity: A Complex Relationship
While the true extent of human longevity remains obscured by inaccurate data, Newman suggests a strong link between wealth and lifespan. Wealthier individuals often have access to better healthcare, nutrition, and lower stress levels, potentially contributing to longer lifespans. However, even this relationship is muddied by data issues. Newman cites UN data showing high centenarian rates in regions like Thailand, Malawi, Western Sahara, and Puerto Rico, all of which face challenges in data collection and accuracy.
The Ig Nobel’s Impact: Laughter, Thought, and Hopefully, Change
Newman hopes his Ig Nobel Prize will spark not only laughter but also serious consideration of the flaws in longevity data. He believes that public awareness, even without immediate acknowledgment from the scientific community, is a crucial step towards addressing this issue.
