Title: Unraveling the Intelligence of Jays: Insights from the Marshmallow Test
Written on
Chapter 1: The Intelligence of Jays
Recent research has revealed that jays possess cognitive abilities that surpass our previous understanding. These birds have successfully completed a modified version of the renowned marshmallow test, illustrating their capacity for self-control and higher intelligence.
The marshmallow test is a landmark psychological experiment conceived by Walter Mischel at Stanford University. Its objective was to assess self-control in children by observing how long they could resist the temptation of sweets if they were promised a greater reward later on.
Section 1.1: Understanding the Marshmallow Test
In the classic setup, young participants were offered a choice: eat a marshmallow or Oreo cookie immediately, or wait for a bigger reward. The adult supervising would inform them of the conditions, leaving the children alone with their decision. Researchers recorded their ability to delay gratification.
This experiment aimed to evaluate the connection between early self-control and future life outcomes. Longitudinal studies showed that those who could resist temptation as children tended to have better life trajectories, including lower divorce rates and higher self-esteem.
Section 1.2: Extending the Test to Animals
Similar experiments have been conducted with various animal species, revealing intriguing parallels. For instance, both chimpanzees and cuttlefish exhibited a relationship between self-control and intelligence.
Researchers from the University of Cambridge turned their attention to jays, known for their remarkable cognitive skills, sometimes likened to those of primates. They specifically studied common jays (Garrulus glandarius) and tailored the marshmallow test to their feeding behaviors.
#### Subsection 1.2.1: Tailoring the Test for Jays
Instead of sweets, the jays were presented with three types of food. The most desirable option was worms, which were placed out of reach, while less appealing choices like bread or cheese were readily available. The birds were trained to understand that waiting would lead to their preferred food.
Section 1.3: Results of the Study
A total of ten jays participated in the study. The least patient bird only lasted 20 seconds before giving in, while an exemplary jay, named JayLo, managed to wait for an impressive five and a half minutes.
Dr. Alex Schnell, the lead researcher, expressed amazement at JayLo's ability to resist the cheese for so long, highlighting the bird's focus on the reward rather than the temptation. This strategy mirrors those used by children and chimpanzees in similar situations.
Post-experiment, the jays undertook five cognitive tasks, which revealed that those with greater self-control performed significantly better. This suggests a correlation between self-control and intelligence in birds, indicating that this trait may have evolved independently across various species.

An intriguing development has emerged regarding the asteroid (3200) Phaethon, which is spinning increasingly faster around its axis as it approaches Earth. The reasons behind this phenomenon remain unexplained.
