An oracle erred badly. The most impressive results were turned in by a little-known company in Brazil. A nagging problem reemerged, and some media critics turned profane in their assessments.
So it went for pollsters in the 2024 presidential election. Their collective performance, while not stellar, was improved from that of four years earlier. Overall, polls signaled a close outcome in the race between former President Donald Trump and Vice President Kamala Harris.
That is what the election produced: a modest win for Trump.
This time, CNN’s final national poll said the race was deadlocked – an outcome anticipated by six other pollsters, according to data compiled by RealClearPolitics.
The most striking discrepancy this year was the Marist College poll, conducted for NPR and PBS. It estimated Harris held a 4-point lead nationally at campaign’s end.
Comedian Jon Stewart gave harsh voice to such sentiments, saying of pollsters on his late-night program on election night, “I don’t ever want to fucking hear from you again. Ever. … You don’t know shit about shit, and I don’t care for you.”Comedian Jon Stewart doesn’t like pollsters and had some blistering comments about them on election night. Screenshot, YouTube
Megyn Kelly, a former Fox News host, also denounced pollsters, declaring on her podcast the day after the election: “Polling is a lie. They don’t know anything.”
Two factors seemed to encourage such derision – a widely discussed survey of Iowa voters released the weekend before the election and Trump’s sweep of the seven states where the outcome turned.

The Iowa poll injected shock and surprise into the campaign’s endgame, reporting that Harris had taken a 3-point lead in the state over Trump. The result was likened to a “bombshell” and its implications seemed clear: If Harris had opened a lead in a state with Iowa’s partisan profile, her prospects of winning elsewhere seemed strong, especially in the Great Lakes swing states of Wisconsin, Michigan and Pennsylvania.
The survey was conducted for the Des Moines Register by J. Ann Selzer, a veteran Iowa-based pollster with an outstanding reputation in opinion research. In a commentary in The New York Times in mid-September, Republican pollster Kristen Soltis Anderson declared Selzer “the oracle of Iowa.” Rachel Maddow of MSNBC praised Selzer’s polls before the election for their “uncanny predictive accuracy.” Ratings released in June by data guru Nate Silver gave Selzer’s polls an A-plus grade.
Selzer said afterward she will “be reviewing data from multiple sources with hopes of learning why that (discrepancy) happened.”
It is possible, other pollsters suggested, that Selzer’s reliance on telephone-based surveying contributed to the polling failure. “Phone polling alone … isn’t going to reach low-propensity voters or politically disengaged nonwhite men,” Tom Lubbock and James Johnson wrote in a commentary for The Wall Street Journal.
Trump’s sweep of the seven vigorously contested swing states surely contributed to perceptions that polls had misfired again.
According to RealClearPolitics, Harris held slender, end-of-campaign polling leads in Michigan and Wisconsin, while Trump was narrowly ahead in Arizona, Georgia, Pennsylvania, North Carolina and Nevada.

Trump won them all, an outcome no pollster anticipated – except for AtlasIntel of Sao Paulo, Brazil, a firm “about which little is known,” as The New Republic noted.
AtlasIntel estimated Trump was ahead in all seven swing states by margins that hewed closely to the voting outcomes. In none of the swing states did AtlasIntel’s polling deviate from the final vote tally by more than 1.3 points, an impressive performance.
AtlasIntel did not respond to email requests I sent requesting information about its background and polling technique. The company describes itself as “a leading innovator in online polling” and says it uses “a proprietary methodology,” without revealing much about it.
Its founder and chief executive is Andrei Roman, who earned a doctorate in government at Harvard University. Roman took to X, formerly Twitter, in the election’s aftermath to post a chart that touted AtlasIntel as “the most accurate pollster of the US Presidential Election.”
A significant question facing pollsters this year – their great known unknown – was whether modifications made to sampling techniques would allow them to avoid underestimating Trump’s support, as they had in 2016 and 2020.
Misjudging Trump’s backing is a nagging problem for pollsters. The results of the 2024 election indicate that the shortcoming persists. By margins ranging from 0.9 points to 2.7 points, polls overall understated Trump’s support in the seven swing states, for example.
Some polls misjudged Trump’s backing by even greater margins. CNN, for example, underestimated Trump’s vote by 4.3 points in North Carolina, by more than 6 points in Michigan and Wisconsin as well as Arizona.
Results that misfire in the same direction suggest that adjustments to sampling methodologies were inadequate or ineffective for pollsters in seeking to reach Trump backers of all stripes.

How China cleaned up its air pollution – and what that meant for the climate
How China cleaned up its air pollution: Beijing’s air quality went from hazardous to good while Delhi and Lahore still struggle. Discover how China dramatically reduced pollution since 2013—and why cleaner air may have unintended consequences for global warming and climate change.
Delhi: 442. Lahore: 334. Beijing: 16. These are the levels of PM 2.5, one of the principle measures for air pollution, on November 19. As Pakistanis and Indians struggle with hazardous air quality, in Beijing – a city once notorious for its smog – the air quality is currently rated as good. Ahead of the 2008 Beijing Olympics, the Chinese government was so concerned about pollution that it introduced temporary restrictions on cars, shut down factories and stopped work on some construction sites. The measures worked and one study later found that levels of air pollution were down 30% during the period when the temporary Olympic restrictions were in place. It would take a few more years before the Chinese government implemented a clean air action plan in 2013. Since then, China has achieved a dramatic improvement in its air quality. In this episode of The Conversation Weekly podcast, we speak to Laura Wilcox, a professor at the National Centre for Atmospheric Science at the University of Reading in the UK, to understand how China managed to clean up its air pollution. But Wilcox’s recent research uncovered some unintended consequences from this cleaner air for the global climate: the pollution was actually helping to cool the atmosphere and by taking it away, it may have accelerated global warming. Wilcox explains:
What we’re seeing is a removing of cooling that’s revealing warming that’s already there. So the air pollution isn’t the cause of the warming. It’s just letting us see stuff that we’ve already done.

The Hong Kong high-rise fire shows how difficult it is to evacuate in an emergency
Hong Kong High-Rise Fire: The deadly Hong Kong fire exposes critical challenges in evacuating tall buildings. Learn why stair descent is slower than expected, how human behavior causes delays, and what modern safety features can save lives.
Evacuations of high-rises don’t happen every day, but occur often enough. And when they do, the consequences are almost always severe. The stakes are highest in the buildings that are full at predictable times: residential towers at night, office towers in the day. We’ve seen this in the biggest modern examples, from the World Trade Center in the United States to Grenfell Tower in the United Kingdom. The patterns repeat: once a fire takes hold, getting thousands of people safely down dozens of storeys becomes a race against time. But what actually makes evacuating a high-rise building so challenging? It isn’t just a matter of “getting people out”. It’s a collision between the physical limits of the building and the realities of human behaviour under stress.
It’s a long way down to safety
The biggest barrier is simply vertical distance. Stairwells are the only reliable escape route in most buildings. Stair descent in real evacuations is far slower than most people expect. Under controlled or drill conditions people move down at around 0.4–0.7 metres per second. But in an actual emergency, especially in high-rise fires, this can drop sharply. During 9/11, documented speeds at which survivors went down stairs were often slower than 0.3 m/s. These slow-downs accumulate dramatically over long vertical distances. Fatigue is a major factor. Prolonged walking significantly reduces the speed of descent. Surveys conducted after incidents confirm that a large majority of high-rise evacuees stop at least once. During the 2010 fire of a high-rise in Shanghai, nearly half of older survivors reported slowing down significantly. Long stairwells, landings, and the geometry of high-rise stairs all contribute to congestion, especially when flows from multiple floors merge into a single shaft. Slower movers include older adults, people with physical or mobility issues and groups evacuating together. These reduce the overall pace of descent compared with the speeds typically assumed for able-bodied individuals. This can create bottlenecks. Slow movers are especially relevant in residential buildings, where diverse occupants mean movement speeds vary widely. Visibility matters too. Experimental studies show that reduced lighting significantly slows down people going down stairs. This suggests that when smoke reduces visibility in real events, movement can slow even further as people hesitate, misjudge steps, or adjust their speed.
Human behaviour can lead to delays
Human behaviour is one of the biggest sources of delay in high-rise evacuations. People rarely act immediately when an alarm sounds. They pause, look for confirmation, check conditions, gather belongings, or coordinate with family members. These early minutes are consistently some of the costliest when evacuating from tall buildings. Studies of the World Trade Center evacuations show the more cues people saw – smoke, shaking, noise – the more they sought extra information before moving. That search for meaning adds delay. People talk to colleagues, look outside windows, phone family, or wait for an announcement. Ambiguous cues slow them even further. In residential towers, families, neighbours and friend-groups naturally try to evacuate together. Groups tend to form wider steps, or group together in shapes that reduce overall flow. But our research shows when a group moves in a “snake” formation – one behind the other – they travel faster, occupy less space, and allow others to pass more easily. These patterns matter in high-rise housing, where varied household types and mixed abilities make moving in groups the norm.
Why stairs aren’t enough
As high-rises grow taller and populations age, the old assumption that “everyone can take the stairs” simply no longer holds. A full building evacuation can take too long, and for many residents (older adults, people with mobility limitations, families evacuating together) long stair descents are sometimes impossible. This is why many countries have turned to refuge floors: fire- and smoke-protected levels built into towers as safe staging points. These can reduce bottlenecks and prevent long queues. They give people somewhere safe to rest, transfer across to a clearer stair, or wait for firefighters. Essentially, they make vertical movement more manageable in buildings where continuous descent isn’t realistic. Alongside them are evacuation elevators. These are lifts engineered to operate during a fire with pressurised shafts, protected lobbies and backup power. The most efficient evacuations use a mix of stairs and elevators, with ratios adjusted to the building height, density and demographics. The lesson is clear: high-rise evacuation cannot rely on one tool. Stairs, refuge floors and protected elevators should all be made part of ensuring vertical living is safer.Milad Haghani, Associate Professor and Principal Fellow in Urban Risk and Resilience, The University of Melbourne; Erica Kuligowski, Principal Research Fellow, School of Engineering, RMIT University, and Ruggiero Lovreglio, Professor in Digital Construction and Fire Engineering, Te Kunenga ki Pūrehuroa – Massey University This article is republished from The Conversation under a Creative Commons license.
