On a day in September, snowflakes began to fall inside MIT’s Pierce Laboratory. Researchers released liquid carbon dioxide from a pressurized tank, causing it to freeze into solid particles. These were mixed into cement paste and formed into small discs, sealed with vegetable oil to preserve moisture and exclude air. Lasers were used to track…
In 1927, psychologist L. L. Thurstone introduced a concept in his paper, “A law of comparative judgment,” suggesting that individuals choose the option with the highest value to them among several alternatives, despite not being able to assign a specific value to their choice. Thurstone’s work laid the foundation for psychometrics, which aims to measure…
Cloudy and turbulent waters often pose a challenge for remotely operated underwater vehicles. These vehicles stir up sediment when they settle on the seafloor or dig into sandbeds, obstructing the view of onboard cameras. Typically, operations have to pause until the sediment clears. However, a new mapping technique by MIT and the Woods Hole Oceanographic…
If a friend treats you to coffee, you might return the favor next time. Behavioral economic studies have long noted this pattern of reciprocal generosity. However, anthropologists and social scientists have observed that in relationships where power, status, or influence is unequal, such reciprocity is uncommon. Researchers at MIT have now shown experimentally that slight…
