The video centers around a Radiolab episode that examines and contests conventional views of animal intelligence through a humorous and informative competition. Hosted by Latif Nasser, Jad Abumrad, and Robert Krulwich, with participants including Tracy Clayton and Jordan Mendoza, the episode highlights a variety of intelligent animals and unconventional behaviors.
Notable animals discussed include crows, known for their problem-solving skills and memory; slime molds, recognized for their collective intelligence; sperm whales, praised for their complex echolocation and social structures; chickens, celebrated for their perceived ability to play games; and raccoons, noted for their adaptiveness and problem-solving abilities. Contestants Tracy and Jordan also humorously discuss less traditionally intelligent animals, like quokkas and koalas, showcasing their unique survival strategies.
Throughout the competition, a range of criteria such as problem-solving, adaptability, and social behaviors are used to gauge intelligence. The sperm whale is ultimately declared the winner, highlighting both the diverse manifestations of intelligence across species and the value of evaluating animals on their own terms, not just human standards. The segment concludes with acknowledgments and sponsor mentions, encapsulating a thought-provoking exploration of animal cognition.

In this segment, Latif Nasser introduces an episode from Radiolab that challenges common perceptions of animal intelligence. He mentions that his initial list of smart animals, like chimpanzees and dolphins, was incomplete and hints at unexpected animals displaying intelligence. The episode encourages listeners to understand the concept of “umwelt,” the unique perceptual world of animals, and to shift away from human-centric views of intelligence. Pat Walters then explains the episode’s focus on animal intelligence, contrasting it with typical human-centered research. The segment involves a competition where four contestants present arguments about their chosen animal’s intelligence to a panel of judges, including Radiolab hosts Jad Abumrad and Robert Krulwich, and a dog named Macy. The judges are asked to define intelligence to set the criteria for the contest.

In this part of the video, the discussion centers around defining and evaluating animal intelligence. Pat explains the structure of the competition, where judges assess creatures based on their problem-solving abilities, adaptability, and collective intelligence. Tracy Clayton and Jordan Mendoza are introduced as the first contestants. Tracy, advocating for crows, highlights their resourcefulness, ability to solve complex puzzles, and their capacity to mimic human speech. She also mentions their cultural misrepresentation and the significance of crow funerals. Jordan opts for the slime mold, setting the stage for the first round of the animal intelligence showdown.
00:10:00
In this segment, the discussion begins with the concept of crows having funerals. Crows gather around a deceased comrade to understand the cause of death to avoid similar fates. They also have strong memory skills, recognizing faces for up to two and a half years and holding grudges. The conversation humorously suggests renaming a group of crows as a “symposium” instead of a “murder.”
Next, Jordan Mendoza talks about slime molds, describing them as brainless, single-celled organisms capable of complex decision-making. He differentiates between three types: plasmodial, cellular, and humorously, Gary Busey. Plasmodial slime molds can solve problems like mazes efficiently. Cellular slime molds live as freewheeling amoebas but can form super-organisms through chemotaxis when food is scarce. This process is a form of collective altruism where individual cells sacrifice for the species’ survival. Mendoza contrasts this with human indecisiveness and injects humor by referencing Gary Busey and making a joke about voting based on ethnicity.
00:15:00
In this segment, the participants discuss and deliberate on the intelligence and capabilities of crows versus slime molds. Judges and audience members express their amazement at how slime molds, despite their small size, can make sophisticated decisions, while crows are noted for their ability to remember faces and communicate over long periods. Ultimately, the judges vote in favor of the slime mold. The next contestants, Laurel Braitman and Dan Engber, introduce their animals for the following round: Braitman presents sperm whales, highlighting their large brains, complex social lives, and powerful echolocation abilities, while Engber will be championing chickens.
00:20:00
In this segment of the video, Laurel Braitman describes the unique echolocation abilities of sperm whales, facilitated by a specialized organ called the “melon” in their foreheads, functioning as a powerful built-in megaphone. This echolocation is so advanced it can detect squid from up to a mile away and likely conveys complex social messages. Braitman imagines the emotional depth of these echolocated communications, comparing it to knowing precise details about an ex-partner from a distance. She also discusses a theory by neuropsychologist Harry Jerison about “communal self,” suggesting whales and dolphins may experience shared emotions collectively rather than individually. Braitman cites examples of empathetic behavior among whales, including aiding struggling swimmers and adopting a deformed dolphin into their pod. The discussion then transitions to another speaker, Dan Engber, who introduces the surprising intelligence of chickens, particularly their prowess in playing tic-tac-toe against humans.
00:25:00
In this segment, Dan Engber recounts the story of the IQ Zoo in Hot Springs, Arkansas, run by scientists Marian and Keller Breland, who trained animals to perform various behaviors, like ducks playing piano or rabbits driving fire trucks. Their most popular act featured a chicken seemingly playing tic-tac-toe, called the Bird Brain. However, Dan reveals that the chicken wasn’t actually playing the game; instead, a computer decided the moves, and the chicken just pecked to make the move appear. He humorously reflects on how humans often lost against the chicken, emphasizing the point that humans and animals share cognitive similarities, challenging the notion of a wide intelligence gap between species. His talk culminates with a call to recognize this common ground and kinship among all species.
00:30:00
In this segment, the discussion revolves around animal intelligence, focusing on sperm whales and their emotional capabilities. It transitions into a competition judging the intelligence of various animals, including a crow, slime mold, sperm whale, and chicken. The next part of the competition involves new challenges, pairing competitors with their previous nemeses and highlighting smart mammals not commonly considered. Dan Engber and Laurel Braitman present the raccoon as their smart mammal, citing historical anecdotes and early 20th-century scientific studies showcasing raccoons’ problem-solving abilities and intelligence.
00:35:00
In this segment of the video, researchers observed that raccoons, such as Tom, Jim, Jack, and Dolly, displayed high intelligence by escaping puzzle boxes and often ignoring food rewards, suggesting their actions were driven by curiosity. Unlike cats, raccoons could also learn from observing humans, leading to a consensus that raccoons were highly intelligent, possibly on par with primates. However, this idea was later challenged, and psychology shifted focus to studying nameless lab rats. Despite vanishing from labs and urban growth, raccoons adapted to cities, with urban raccoons becoming even smarter. “Mr. Raccoon,” a humane raccoon trapper, described raccoons as intelligent and persistent, capable of learning how to break into homes. The segment also briefly introduces a discussion on marsupials, particularly the quokka, touted for its fascinating survival strategies.
00:40:00
In this segment of the video, the discussion focuses on unconventional animal behaviors and intelligence. Tracy Clayton humorously talks about quokkas, which distract predators by throwing their offspring towards them and highlights the practicality of this survival strategy as it ensures the continuation of their genetic line. Jordan Mendoza, on the other hand, discusses why koalas might be considered the “dumbest” animals, citing their small and smooth brains and an amusingly unproductive daily schedule. Despite their apparent lack of traditional intelligence, Mendoza suggests that koalas have optimized their lives around basic pleasures, such as eating and sleeping, which could be seen as a unique form of intelligence. The segment combines humor and interesting facts about animal behaviors to discuss different forms of intelligence.
00:45:00
In this part of the video, the final judging takes place for determining the smartest animal among the contenders, which include a crow, slime mold, sperm whale, chicken, raccoon, and marsupials. Amidst some humorous commentary and a bribery incident involving a giant bone, the decision is turned over to the audience’s applause. The sperm whale is declared the winner, and Laurel Braitman is awarded a beta fish as a prize. The segment concludes with thank-yous to contributors, judges, and staff, along with mentions of support from various foundations and a plug for Laurel Braitman’s memoir.
