Behavior

Prof. of the practice Donald Sull speaks with Fortune reporter Lindsey Leake about the common misconceptions found in corporate company culture. “People often think that high performance is an excuse for abusive behavior—they confuse disrespectful and bullying behavior for maintaining high standards,” say Sull. “But it’s possible to set the bar for performance high without berating or bullying people. And to the extent these toxic managerial behaviors drive high performers out of the organization, the abusive behavior undermines performance.”

Prof. David Rand speaks with New York Times reporters Tiffany Hsu and Stuart A. Thompson about the challenges of stopping the spread of misinformation. “It seems like an easy enough problem: there’s the true stuff and there’s the false stuff, and if the platforms cared about it, they would just get rid of the false stuff,” says Rand. “Then we started working on it and it was like, ‘Oh God.’ It’s actually way more complicated.”

MIT spinout, Cogito, uses “advanced voice analytics to scrutinize voice tons and speech patterns, not just during customer interactions but also within internal team communications,” reports Andre Shojaie for Forbes. “By providing real-time feedback to representatives, Cogito helps them adjust their emotional tone and empathy levels accordingly,” explains Shojaie. “This application significantly reduces stress and cultivates a supportive work environment by enhancing interpersonal interactions among team members.”

Forbes reporter Ulrich Boser spotlights Prof. Rosalind Picard and her work toward advancing “the capability of computers to recognize human emotions.” “AI can enhance learning, and chatbots can supplement many aspects of teaching and tutoring but true success lies in establishing better tutoring platforms to support – not replace – teachers,” writes Boser. 

MIT scientists studying parrots have discovered higher intelligence than previously thought, with some birds besting five-year-old children at logic games. With a tablet computer, parrots “have even figured out how to communicate using modern video conferencing technology,” writes Mack DeGeurin for Popular Science. When shown pictures of other parrots they had previously chatted with, “the parrots repeatedly requested to chat with their long-distance friends.”

Harrison White '50, PhD '55, “a theoretical physicist-turned-sociologist who upended the study of human relations and society” has died at age 94, reports Michael Rosenwald for The New York Times. “With his background in physics, Professor White viewed humans as nodes within social networks,” writes Rosenwald. “Those networks operated in complex ways that shaped economic mobility, financial markets, language and other social phenomena.”

Researchers at MIT have designed an “AI-powered chatbot that simulates a user’s older self and dishes out observations and pearls of wisdom,” reports Ian Sample for The Guardian. “The goal is to promote long-term thinking and behavior change,” says graduate student Pat Pataranutaporn. “This could motivate people to make wiser choices in the present that optimize for their long-term wellbeing and life outcomes.”

On NPR’s Short Wave, climate correspondent Lauren Sommer reports on MIT researchers using artificial intelligence to decode the secret language of sperm whales. Prof. Daniela Rus says, “it really turned out that sperm whale communication was indeed not random or simplistic but rather structured in a very complex, combinatorial manner.”

Researchers from MIT and elsewhere have used quantitative and computational methods to analyze animal communication, reports Emily Anthes for The New York Times.

MIT researchers have used advancements in machine learning and computing to help decode whale vocalizations, reports Sarah Kuta of Smithsonian Magazine. “If researchers knew what sperm whales were saying, they might be able to come up with more targeted approaches to protecting them,” Kuta explains. “In addition, drawing parallels between whales and humans via language might help engage the broader public in conservation efforts.”

A new analysis of years of vocalizations by sperm whales in the eastern Caribbean has provided a fuller understanding of how whales communicate using codas, reports Will Dunham of Reuters. Graduate student Pratyusha Sharma explained that: "The research shows that the expressivity of sperm whale calls is much larger than previously thought."

New Scientist reporter Clare Wilson writes that a new analysis by MIT researchers of thousands of exchanges made by east Caribbean sperm whales demonstrates a communication system more advanced than previously thought. “It’s really extraordinary to see the possibility of another species on this planet having the capacity for communication,” says Prof. Daniela Rus.

Researchers from MIT and elsewhere have uncovered a phonetic alphabet used by sperm whales, which provides “key breakthroughs in our understanding of cetacean communication,” reports Brain Heater for TechCrunch. “This phonetic alphabet makes it possible to systematically explain the observed variability in the coda structure,” says Prof. Daniela Rus, director of CSAIL. “We believe that it’s possible that this is the first instance outside of human language where a communication provides an example of the linguistic concept of duality of patterning. That refers to a set of individually meaningless elements that can be combined to form larger meaningful units, sort of like combining syllables into words.”

Associated Press reporter Maria Cheng spotlights a new study by MIT researchers that identifies a “phonetic alphabet” used by whales when communicating. “It doesn’t appear that they have a fixed set of codas,” says graduate student Pratyusha Sharma. “That gives the whales access to a much larger communication system.” 

Using machine learning, MIT researchers have discovered that sperm whales use “a bigger lexicon of sound patterns” that indicates a far more complex communication style than previously thought, reports Lauren Sommers for NPR. “Our results show there is much more complexity than previously believed and this is challenging the current state of the art or state of beliefs about the animal world," says Prof. Daniela Rus, director of CSAIL.
