The Original Alien Craze: When People Believed in Martians

At the turn of the 20th century, millions of Americans, including elite scientists, major newspapers, and cultural icons, were convinced that Mars was home to an advanced civilization. In this episode, Michael Shermer speaks with award-winning science journalist David Baron about one of the most ast

Episode Summary

Executive Summary: The episode explores David Barron’s book on the early-1900s Mars craze, showing how incomplete science, media amplification, religion, and cultural anxiety turned Mars into a real-world object of belief. Barron argues that Percival Lowell’s influential but wrong ideas were understandable in context, inspired later science and science fiction, and still echo today in SETI, UFO culture, and Mars optimism.

Main Topics: Origins of the Mars craze: The conversation traces the public fascination with Mars from Schiaparelli’s canal observations to Lowell’s highly influential claims about a Martian civilization. Percival Lowell’s role and psychology: Barron explains how Lowell’s status, ambition, class, and possible bipolar tendencies helped him champion the canal theory and resist criticism. Science, media, and mass belief: The discussion emphasizes how newspapers, magazines, and sensational images amplified ambiguous evidence into widely accepted “facts.” Religion, spiritualism, and cultural anxiety: Mars filled a perceived gap left by science’s erosion of traditional religion, offering supernatural or morally superior beings that could guide humanity. Evolution, future humans, and alien design: The speakers connect alien imagery to Darwinian thinking, Victorian ideas of progress, and the assumption that Martians were an advanced version of ourselves. Legacy for science fiction, rocketry, and astrobiology: Even though Lowell was wrong, his ideas inspired Hugo Gernsback, Robert Goddard, Carl Sagan, and the broader public imagination about space exploration. Modern parallels: SETI, UAPs, and speculative science: The episode draws parallels between early Mars enthusiasm and modern patterns of interpreting blurry data, including anomalous stars, UFOs, and technosignatures.

Key Arguments: Ambiguous astronomical data can become culturally powerful when people want a compelling explanation for what they see. Lowell’s canal theory was scientifically wrong, but it was not irrational given the limits of 19th-century telescopes and Mars knowledge. Media incentives favor exciting claims over skeptical caution, which is why Lowell’s ideas spread more than those of his critics. The Mars craze was partly a substitute for religion: many people wanted a morally superior civilization that could answer existential questions. Victorian ideas of evolution encouraged the belief that aliens or Martians would be more advanced, peaceful, and intelligent versions of humans. Public belief in Mars was shaped by broader social instability, including class inequality, anarchism, assassinations, and rapid technological change. Speculative ideas can still be productive because they inspire science fiction, engineering, and real exploration, even when the original claim is false. Modern SETI and UFO culture repeat the same cognitive pattern: sparse data plus imagination produces strong narratives.

Data Points: Research duration: 7 years - Barron says it took seven years to research The Martians. Illustrations in the book: More than 100 - The book includes many historical images, maps, and depictions of Martians. Mars close approaches: Every 26 months - Mars and Earth come close frequently due to their orbits. Especially close alignment: About every 15 years - The conversation notes particularly favorable Mars-Earth viewing opportunities. Mars distance at closest approach: About 35 million miles - Used to explain how difficult telescopic observation was. Lowell Observatory founding: 1894 - Lowell established the observatory in Flagstaff, Arizona. Year of Mars boom mini-craze: 1892 - A triangle-of-lights report and Flammarion’s ideas sparked an early craze. Tesla’s Mars signal announcement: December 31, 1900 - Tesla publicly claimed he may have received signals from Mars on New Year’s Eve. Terrace of acceptance of Mars idea: By 1908-1909 - The transcript says pastors and even Alexander Graham Bell treated intelligent life on Mars seriously by then. Viking-era Mars image year: 1976 - The famous “face on Mars” photograph came from the Viking orbiter. Potential civilization duration estimate: 410 years - Shermer mentions a calculation of average civilization length in a Scientific American column. Alternative civilization-duration estimate: 10,000 years - SETI advocates responded that civilizations may last much longer than Shermer’s estimate.

Pivotal Quotes: "The Martians were better than us. They were more advanced than us. They were more moral, more peaceful." — David Barron: Barron summarizes how people at the time imagined Martians, contrasting this with H.G. Wells’s monstrous Martians. "There were these hideous, monstrous creatures. That is not the way people pictured the Martians at the time." — David Barron: He contrasts popular 20th-century fiction with the actual turn-of-the-century Martian craze. "Questions Mars might answer." — Michael Shermer: Shermer cites the historical newspaper framing of what people hoped to learn from Martians, emphasizing the quasi-religious dimension.

Implications: The episode shows how fragile perception, media hype, and human longing can turn weak evidence into belief. It warns listeners to separate imagination from proof while recognizing that even mistaken ideas can inspire science, engineering, and exploration.
