A study conducted by Loma Linda University has invalidated the prevailing belief that juvenile rattlesnakes possess a diminished capacity to regulate venom expulsion compared to adults.

洛瑪琳達大學（Loma Linda University）的一項研究證明，先前普遍認為幼年響尾蛇控制毒液排出能力較成年蛇差的觀點是不成立的。

The research, published in the journal Toxins, establishes that juvenile rattlesnakes maintain volumetric control over venom delivery, contradicting the long-standing hypothesis that they indiscriminately discharge their entire venom supply. Conversely, the data indicates that adult specimens present a higher clinical risk due to their superior venom capacity and the subsequent delivery of larger quantities during envenomation, which results in more acute symptomatology.

這項發表於《Toxins》期刊的研究指出，幼年響尾蛇能夠控制毒液注射的劑量，反駁了長期以來認為牠們會不分青紅皂白地釋放所有毒液的假設。相反地，數據顯示成年個體由於毒液容量較大，在注射時會傳遞更多毒液，因此臨床風險較高，且導致更急性地出現症狀。

An analysis of the misinformation's provenance reveals that the fallacy emerged in journalistic reports as early as 1967, with significant proliferation facilitated by California-based media outlets between the 1970s and 1990s. This trend persisted across North American media until 2014. The researchers observed that inaccurate reporting frequently relied upon erroneous attributions to emergency responders and medical personnel, whereas academic experts provided more precise data. While reporting accuracy has improved since 2015—likely due to enhanced public education—the misconception remains pervasive. Survey data from Southern California indicates a 53% adherence to the myth among students and a 73% adherence rate among healthcare and emergency professionals.

分析這些錯誤資訊的來源發現，此謬論最早於 1967 年的新聞報導中出現，並在 1970 年代至 1990 年代間透過加州媒體大幅傳播。這一趨勢在北美媒體中持續至 2014 年。研究人員觀察到，不準確的報導經常錯誤地將其歸因於急救人員和醫療人員，而學術專家則提供了更精確的數據。雖然 2015 年以來報導的準確性有所提高（可能歸功於公眾教育的提升），但該誤解依然普遍。南加州的調查數據顯示，53% 的學生與 73% 的醫療及急救專業人員仍認同此迷思。

The institutional implications of this fallacy are multifaceted. In clinical settings, the misconception may precipitate suboptimal care if practitioners succumb to patient or familial pressure for excessive medication. Furthermore, the perceived threat of juvenile snakes has contributed to the anthropogenic depletion of rattlesnake populations, which are critical components of their respective ecosystems. Despite these findings, the researchers maintain that any rattlesnake envenomation constitutes a medical emergency requiring immediate administration of antivenom.

此謬論在制度上的影響是多方面的。在臨床環境中，若從業人員屈服於患者或家屬要求過量用藥的壓力，可能會導致治療不理想。此外，對幼年蛇威脅的感知導致了人為地減少響尾蛇數量，而牠們是其各自生態系統中的關鍵組成部分。儘管有這些發現，研究人員仍強調，任何響尾蛇咬傷均屬於醫療緊急情況，需立即施打抗蛇毒血清。

Current evidence confirms that adult rattlesnakes are more dangerous than juveniles, though all bites require urgent medical intervention.

目前的證據確認成年響尾蛇比幼年蛇更危險，但所有咬傷都需要緊急醫療干預。
