Why Is Paul Ehrlich So Hard to Ignore?

Blame evolution, which primes us to be alert to danger, even when we know better.

Summary: Paul Ehrlich is a biologist who has been making dire predictions about the fate of humanity for decades. He has been wrong on every count, yet he still commands attention and influence in the media and academia. This article examines why Ehrlich’s pessimism persists despite the overwhelming evidence of human progress and prosperity.


This article originally appeared in the Wall Street Journal.

Paul Ehrlich’s memoir, “Life: A Journey through Science and Politics,” comes out next week. It probably won’t sell as many copies as “The Population Bomb” (1968). But neither will it flop—and it should. Mr. Ehrlich, 90, whom the media treat with an obsequious deference—see the recent cringe-worthy segment on CBS’s “60 Minutes”—will again profit from the capitalist consumption he’s spent his life decrying.

Mr. Ehrlich is a purveyor of “doom porn” at a time when the world has never been more prosperous. Developed countries are astonishingly rich, and even in developing nations the share of the population in absolute poverty has fallen to single digits. Mr. Ehrlich in 1968 predicted mass starvation; instead obesity is rising, even in Africa. So why don’t people ignore him? Ignorance is no excuse when we carry the entirety of human knowledge in our pockets.

The answer is that humans have evolved to prioritize bad news. “Organisms that treat threats as more urgent than opportunities,” wrote Nobel Prize-winning behavioral psychologist Daniel Kahneman, “have a better chance to survive and reproduce.”

As Peter H. Diamandis and Steven Kotler explain in “Abundance: The Future Is Better Than You Think,” our brains have limited bandwidth and need to focus when a threat arises. Most information is first sifted through the amygdala, a part of the brain that is “responsible for primal emotions like rage, hate, and fear,” Messrs. Diamandis and Kotler write. “The amygdala is always looking for something to fear.”

That is a very powerful impulse that can deceive even the most dispassionate and rational observers. A study by Marc Trussler and Stuart Soroka found that even when people expressly say they are interested in more good news, eye-tracking experiments show they are in fact much more interested in bad news.

Mr. Ehrlich built a career pandering to these inclinations, starting with “The Population Bomb.” In 1970 he said that “if I were a gambler, I would take even money that England will not exist in the year 2000.” That got the attention of Julian Simon, a University of Maryland economist, who a decade later challenged Mr. Ehrlich to a wager.

It was structured as a commodities futures contract. Simon agreed to sell Mr. Ehrlich $200 each worth of chromium, copper, nickel, tin and tungsten in 1990 at 1980 prices. The bet would pay off for Mr. Ehrlich if the metals became scarcer and thus costlier. On the settlement date, the total price had declined from $1,000 to $423.93. Mr. Ehrlich mailed Simon a check for the balance, $576.07.

While issuing one failed prognostication after another, Mr. Ehrlich went on to win a series of prestigious prizes. When the MacArthur Foundation gave him a “genius grant” in 1990, Simon quipped: “MacArthur! I can’t even get a McDonald’s!”

What does Mr. Ehrlich’s memoir say about the bet? The book isn’t out, but its index is already available on Amazon. Simon’s name doesn’t appear.

Global Extreme Poverty Rate Fell from 2022 to 2025

“Global poverty estimates up to 2023 were updated today on the Poverty and Inequality Platform (PIP), including nowcasted estimates up to 2025. The update includes three main changes to the PIP data (See the What’s New document for more details): First, the update brings new survey data for several country-years, including important updates to data from India; second, it includes the adoption of the 2021 Purchasing Power Parities (PPPs); and third, based on the new PPPs and new survey data, including new national poverty lines, the update revises the global poverty lines.

As a result of these combined changes, the global extreme poverty rate in 2022 is revised up from 9.0 to 10.5 percent, corresponding to an increase in the number of individuals living below the international poverty line from 713 to 838 million…

While revised poverty lines, underlying data revisions, and changes in PPPs affect the level of poverty, from a historical lens, the trends remain similar. The following graph shows the estimated poverty rates by regions since 1990. The graph also depicts the updated nowcasts of poverty following the methodology introduced in the September 2024 update. The nowcast suggests a modest decline in the global extreme poverty rate from 10.5 percent in 2022 to 9.9 percent in 2025. Based on the latest data, the South Asia region experienced the most significant decline in extreme poverty between 2022 and 2025. Conversely, the Middle East and North Africa was the only region to experience an increase in poverty during this period, up from 8.5 percent in 2022 to 9.4 percent in 2025.”

Jamaica’s Poverty Prevalence Has Declined Dramatically

Planning Institute of Jamaica (PIOJ) Director General, Dr. Wayne Henry, disclosed that it was ‘the lowest figure ever recorded since poverty rates were first measured in 1989.'”

Morocco’s Multidimensional Poverty Halved Since 2014

“The High Commission for Planning (HCP) has unveiled a new map of multidimensional poverty in Morocco, drawing on data from the 2014 and 2024 general censuses. This initiative aims to offer a clearer picture of the various forms of deprivation tied to deficits in education, health, housing, and access to basic infrastructure.

According to HCP, Morocco has seen a substantial decline in multidimensional poverty between 2014 and 2024. The proportion of the population experiencing poverty fell from 11.9% to 6.8%, representing a drop from around 4 million to 2.5 million people. The intensity of poverty, measured by the average deprivation rate, also saw a slight decrease, from 38.1% to 36.7%. As a result, the overall Multidimensional Poverty Index was nearly cut in half, falling from 4.5% to 2.5%.”

Poverty Declines Significantly in Bhutan from 2017 to 2022

“The report highlights Bhutan’s remarkable progress in poverty reduction, with the national poverty rate declining from 28 percent to 11.6 percent during this period. Key drivers include robust economic growth, improved labor market outcomes, enhanced agricultural productivity, effective COVID-19 relief programs, and strong remittance inflows.”
