Anxious People More Apt to Make Bad Decisions

New brain evidence provides insight into why highly anxious people are worst at making decisions when things get unpredictable.

Highly anxious people have more trouble deciding how best to handle life’s uncertainties. They may even catastrophize, interpreting, say, a lovers’ tiff as a doomed relationship or a workplace change as a career threat.

In gauging people’s response to unpredictability, scientists at the University of California, Berkeley, and the University of Oxford found that people prone to high anxiety have a tougher time reading the environmental cues that could help them avoid a bad outcome.

Their findings, reported March 2 in the journal Nature Neuroscience, hint at a glitch in the brain’s higher-order decision-making circuitry that could eventually be targeted in the treatment of anxiety disorders, which affect some 40 million American adults.

“Our results show that anxiety may be linked to difficulty in using information about whether the situations we face daily, including relationship dynamics, are stable or not, and deciding how to react,” said study lead author Sonia Bishop, an assistant professor of psychology at UC Berkeley and principal investigator of the study.

“It’s a bit like being Alice in Wonderland, trying to work out if the same rules apply or if everything is different and if so, what choices you should make,” she added.

For example, a friend may suddenly lash out for no discernible reason. That friend’s behavior could reflect a typical variation in their day-to-day mood or interactions or, more dramatically, an underlying change in their relationship with you. The challenge for a person prone to anxiety is assessing the situation in context of what else has happened recently and responding appropriately.

Bishop and fellow researchers used decision-making tasks, behavioral and physiological measurements and computational models to gauge the probabilistic decision-making skills of 31 young and middle-aged adults whose baseline anxiety levels ranged from low to extreme.

Probabilistic decision-making requires using logic and probability to handle uncertain situations, drawing conclusions from past events to determine the best choice.

“An important skill in everyday decision-making is the ability to judge whether an unexpected bad outcome is a chance event or something likely to reoccur if the action that led to the outcome is repeated,” Bishop said.

The researchers’ measures also included eye-tracking to detect pupil dilation, an indicator that the brain has released norepinephrine, which helps send signals to multiple brain regions to increase alertness and readiness to act.

Participants were asked to play a computerized “two-armed bandit-style” game in which they repeatedly chose between two shapes, one of which, if selected, would deliver a mild to moderate electrical shock.

To avoid getting shocked, participants needed to keep track of the shape that most frequently delivered electrical jolts. During one part of the game, the shock-delivering shape did not change for a long stretch of time.

However, during another part of the game, it changed more frequently. Highly anxious people had more trouble than their less anxious counterparts adjusting to this and thus avoiding shocks.

“Their choices indicated they were worse at figuring out whether they were in a stable or erratic environment and using this to make the best choices possible,” Bishop said.

Also weaker in highly anxious participants was their pupil response to receiving a shock (or not) during the erratic phase of the game.

Typically, our pupils dilate when we take in new information, and this dilation increases in volatile environments. Smaller pupils suggested a failure to process the rapidly changing information that was more prevalent during the erratic phase of the game.

“Our findings help explain why anxious individuals may find decision-making under uncertainty hard as they struggle to pick up on clues as to whether they are in a stable or changing situation,” Bishop said.

In addition to Bishop, co-authors and researchers on the study were Timothy Behrens, Michael Browning, Gerard Jocham and Jill O’Reilly at the University of Oxford in England.

The study was funded by grants from the European Research Council and the National Institutes of Health.

UC Berkeley Named Top Public University in the U.S. and No. 7 in the World by ‘U.S. News’

Berkeley has been consistently awarded the distinction of the U.S.’s top public university since the Best Global Universities list was first published in 2014. “A strong position in the Best Global Universities rankings recognizes a school’s profound commitment to world-class research and cross-border academic excellence,” said LaMont Jones, managing editor for education at U.S. News.

The 2026 Best Global Universities rankings evaluated 2,250 research institutions from more than 100 countries

By Lila Thulin

U.S. News & World Report has ranked UC Berkeley No. 7 in its 2026 list of the best global universities, which assesses more than 2,250 research institutions worldwide.

Berkeley also claimed the honor of top public university in the U.S.

Released on Monday, the list evaluates universities from more than 100 countries on 13 metrics such as global and research reputation (as reported by academics and peers) and number of highly cited scholarly papers.

Berkeley has been consistently awarded the distinction of the U.S.’s top public university since the Best Global Universities list was first published in 2014.

“A strong position in the Best Global Universities rankings recognizes a school’s profound commitment to world-class research and cross-border academic excellence,” said LaMont Jones, managing editor for education at U.S. News.

The rankings also assess a university’s strength in various subject areas; these assessments are separate from U.S. News’ 2026 Best Graduate Programs rankings released in April.

This year, Berkeley was named in the top three nationally in seven subject areas – environment/ecology, ecology, water resources, physics, computer science, chemistry, and engineering – and in the top five for a total of 17 subjects. Subject rankings are based heavily on scholarly publications and citations as well as reputation.

In September, U.S. News also released its 2026 Best Colleges list, in which Berkeley was also named the No. 1 public institution among American universities.

That honor joins other accolades judging campus to be the best public university in the country, such as those from Forbes, The Wall Street Journal and Times Higher Education.

Farwest Region Deltas Celebrate Centennial With “September Breakfast” Honoring Vivian Osborne Marsh

The region was established in 1925 under the leadership of Vivian Osborne Marsh, who became its first Regional Director. Marsh was a pioneering scholar and civic leader, earning recognition as the first Black woman to receive both a bachelor’s and a master’s degree in anthropology from UC Berkeley.

Hundreds of members of Delta Sigma Theta Sorority, Inc., and their guests gathered at the Martin Luther King Jr. Student Union at the University of California, Berkeley, to mark the 100th anniversary of the sorority’s Farwest Region.

Marsh went on to serve as Delta Sigma Theta’s 7th National President, where she launched the sorority’s National Library Project to expand access to books in underserved Black communities in the South. During her presidency, the organization also became a prominent voice in the civil rights movement, lobbying Congress to pass anti-lynching legislation.

Bak in the Bay Area, Marsh devoted her career to advancing educational opportunities, mentoring young people, and strengthening community life. That commitment continues to shape the region, which supports initiatives in education, social justice, and economic development. Current projects include raising scholarship funds for students at Historically Black Colleges and Universities, voter education campaigns, and health and wellness programs.

A century after its founding, the Farwest Region of Delta Sigma Theta remains active across California and other western states, carrying forward Marsh’s vision of service and advocacy.

On Labor Day weekend two of the world’s most celebrated musicians and cultural ambassadors, Grammy Award–winning vocalist Angélique Kidjo and legendary cellist Yo-Yo Ma join forces for an evening of music, history, and cultural dialogue at UC Berkeley’s historic Hearst Greek Theatre.

Both Kidjo and Ma have built careers not only as great performers but as passionate advocates for cultural understanding. Sarabande Africaine is as much a conversation about shared heritage as it is a musical performance, blending genres, geographies, and histories.

“Every day there are moments when all of us can feel we are on the inside of something and also when we feel we are on the outside of something,” said Yo-Yo Ma. “To be able to understand both at the same time and oscillate between the two gives us a larger perspective on the world.”

“If your mind is open, and there is no fear, it’s easier to listen, and to question yourself,” said Kidjo.

The upcoming performance is presented within Cal Performances’ Illuminations: “Exile & Sanctuary” series for the 2025–26 season. The production explores exile as more than just physical displacement, but a disruption in identity and belonging, while sanctuary represents both refuge and the creative space where new connections and communities can take shape.

Cal Performances’ Illuminations bridges performances with UC Berkeley’s academic research, pairing the arts with conversations about urgent global issues.

Kidjo’s continued partnership with Cal Performances includes her 2021–22 artist-in-residence, premiering her music-theater work Yemandja, set in 19th-century West Africa during the transatlantic slave trade.

She also participated in the Bias in Our Algorithms and Society panel alongside campus leaders like Jennifer Chayes, and joined the Black Studies Collaboratory for a dialogue on music, diaspora, and the world.

She has since returned to Berkeley for multiple performances, most recently in 2024 at Zellerbach Hall.

Yo-Yo Ma’s history with Cal Performances spans decades, beginning in 1997. One notable project includes the 2018 performance of Bach’s complete cello suites at the Greek Theatre, a testament to his devotion to creating “transformative concert experiences in iconic spaces.”
