This episode updates a previous discussion on why people hate rats, focusing on New York City's efforts to combat its rat population, including the appointment of a "Rat Czar." It delves into the historical association of rats with disease, particularly challenging their primary role in the Black Death, and explores the cultural and psychological reasons behind human revulsion towards them, contrasting Western views with cultures where rats are revered.
Summarized by Podsumo
New York City appointed a "Rat Czar," Kathy Karate, to lead efforts against a surging rat population, emphasizing sanitation and understanding rat behavior rather than just "wholesale slaughter."
Recent scientific research, notably by Neal's Christian Stenseth, suggests that human ectoparasites (like body lice and fleas) were more likely vectors for the Black Death than rats and their fleas, challenging a long-held belief.
Bethany Brookshire highlights that the classification of an animal as a "pest" is subjective and cultural, driven by human perceptions of where animals "belong" and their perceived threat, contrasting with cultures like the Karni Mata Temple in India where rats are sacred.
Economist Ed Glazer views rats as "agents of negative externalities" but also "natural city partners," suggesting that while some control is necessary, the intense revulsion might be an outdated response given their minor role in modern disease transmission.
Beyond property damage and minor public health risks like leptospirosis, rats significantly impact human mental well-being, causing documented stress, anxiety, and depression for those living in close proximity.
"“We really hate them. We hate their success because their success feels like our failure.” — Bethany Brookshire"
"“So blaming the rat is pretty much game over in terms of the rats global reputation.” — Ed Glazer"
"“I usually say to my students that if you want to have enemies within science study plague because there are so many strong personalities and there are so many different opinions and they hate each other.” — Neal's Christian Stenseth"
