Rice University research finds that gender does matter when taking risks in business

When motorcycle daredevil Evel Knievel leapt over cars, vans and fountains, it was little surprise that the person pulling those stunts was a man. That's not to say women never partake in high-risk behavior (Danica Patrick, anyone?). But decades of research confirm that men really are more inclined to take risks.

Snake River Canyon and the Indy 500 aside, economic life offers plenty of risks as well. When these risks involve investing, men under certain circumstances are more likely than women to take dangerous leaps, but why?

Rice Businesses professor Vikas Mittal joined Xin He of the University of Florida and J. Jeffrey Inman of the University of Pittsburgh in three studies to examine why men and women engage in risky business. Specifically, the team wanted to test whether each gender's risk-taking was moderated by a trait called issue capability: a decision-makers' belief that he or she can solve an issue.

The team grounded their work in agency-communion theory. This posits that men are more driven by goals that further self-interest ("agentic" goals) and women are more driven by goals that further coexistence ("communion" goals).

Based on this theory, the researchers hypothesized that men making investment decisions would take greater risks as their issue capability rose. This would occur because men, who are more focused on maximizing gains, would become more risk-seeking as their self-capability perceptions increased.

Conversely, the researchers theorized, women who faced similar investment decisions would focus on avoiding loss — even when their issue capability rose. This fundamental difference in investing perspective — men trying to maximize any gain versus women trying to minimize any loss – would be at the heart of a diametrically opposite stance on financial risk-taking.

All three studies proved the theory to be correct.

In the first study, the researchers asked men and women to wager money on Daily Double questions in "Jeopardy!" The male contestants with higher issue capability (i.e. demonstrated knowledge of the category) took the biggest risks. The women contestants showed equal levels of betting behavior regardless of whether they had high issue capability or not.

In the second study, the researchers dove into the psychology underlying gender and issue capability. First, the researchers primed male and female participants to believe they had either good or bad track records with risky investment decisions. Then they asked both groups to imagine they could invest $20,000 at varying levels of risk.

When it came to investing for gains, the researchers found, the women's beliefs about their issue capability made no real difference in their financial choices. Even after they had been primed to think they were highly capable investors, the women participants were less prone than the men to focus on the upside potential

And the men? Those who believed they were "capable" made the riskiest investment decisions. They also reported the highest number of thoughts about the positive potential of the various investment scenarios. Statistical analysis proved that these gain-maximization thoughts egged them on in their risk-taking.

On the other hand, those male participants who weren't primed to feel capable showed risk-taking patterns identical to that of the female participants. The results, in other words, suggest that the key difference between men and women's risk-taking is not innate — but stems from their self-conviction in investment competence.

The third study examined these processes in yet another way, by giving female and male participants the chance to maximize gains through making investments in stocks, or to minimize losses through buying insurance. Once again, the men primed to see themselves as ace investors made the riskiest investments. The women who felt themselves especially capable kept their risk-taking steady.

The women's behavior only changed when they thought they were subpar investors. When both women and men were told they were stock market duds, the women were more likely than the men to buy insurance — in other words, to take traditional measures to defend against loss.

Risk-taking choices, in other words, can no longer be written off as just boys being boys or girls being girls. More accurately, boys will be boys when a male investor thinks he is especially capable and that taking a risk will benefit him personally. That's not always a good thing. A female investor, who will typically focus on minimizing potential loss, can contribute a lot to investing decisions. Taking a big risk, as many an investor knows, isn't always the best move.

Mittal's findings inspire a list of possibilities for future research. What will happen to these behaviors as more women assume leadership jobs and more men get to show their skill as caregivers? Should senior management teams have both male and female representation to balance out the upsides and downsides of investment decisions? What about at home: would household decisions change for the better if both the man and the woman contributed their perspective?

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”
