Diving into the Monty Hall Dilemma: testing the Arithmetic Fallacy with ghost-catfish

The Monty Hall problem, a renowned probability puzzle, has been extensively investigated across various species and cultures, including humans (Granberg, D., 1999), pigeons (Herbranson, W. T., 2012), and monkeys (Watzek, J. et al., 2018). Building upon this rich literature, we embarked on a novel replication study utilizing ghost catfish (Kryptopterus vitreolus) as experimental subjects. After a preliminary phase involving multiple species, we selected ghost catfish due to their suitability for experimentation and ease of tracking using Zantiks technology. Subjects were trained and tested using a Zantiks machine to record behavioral responses and administer rewards accordingly. By extending the Monty Hall paradigm to a non-traditional model organism, this study contributes to the broader understanding of decision-making processes across diverse taxa, shedding light on the cognitive abilities of ghost catfish and providing valuable insights into comparative cognition research.
