Theoretically, product evaluations should be impartial and unbiased. However, this assumption overlooks a crucial truth about product evaluators: They are human beings who are concerned about maintaining credibility with their audience, especially their peer evaluators.

Because evaluators must also care about being perceived as legitimate yet skillful themselves, certain social pressures are at play that potentially influence their product reviews.

Research by Minjae Kim (Rice Business) and Daniel DellaPosta (Penn State) takes up the question of how evaluators navigate those pressures. They find that in some cases, evaluators uphold majority opinion to appear legitimate and authoritative. In other contexts, they offer a contrasting viewpoint so that they seem more refined and sophisticated.

Pretend a movie critic gives an uplifting review of a widely overlooked film. By departing from the aesthetic judgments of cinema aficionados, the reviewer risks losing credibility with their audience. Not only does the reviewer fail to understand this specific film, the audience might say; they fail to understand film and filmmaking, broadly.

But it’s also conceivable, in other situations, that the dissenting evaluator will come across as uniquely perceptive.

What makes the difference between these conflicting perceptions?

Partly, it depends on how niche or mainstream the product is. With large-audience products, Kim and DellaPosta hypothesize, evaluators are more willing to contradict widespread opinion. (Without a large audience, contradicting opinions are like the sound of a tree that falls in a forest without anyone nearby to hear.)

The perceived classiness of the product can affect the evaluator’s approach, as well. It’s easier to dissent from majority opinion on products deemed “lowbrow” than those deemed “highbrow.” Kim and DellaPosta suggest it’s more of a risk to downgrade a “highbrow” product that seems to require more sophisticated taste (e.g., classical music) and easier to downgrade a highly rated yet “lowbrow” product that seems easier to appreciate (e.g., a blockbuster movie).

Thus, the “safe spot” for disagreeing with established opinion is when a product has already been thoroughly and highly reviewed yet appears easier to understand. In that case, evaluators might sense an opportunity to stand out, rather than try to fit in. But disagreeing with something just for the sake of disagreeing can make people think you’re not a fair or reasonable evaluator. To avoid that perception, it might be better to agree with the high rating.

To test their hypotheses, Kim and DellaPosta used data from beer enthusiast site BeerAdvocate.com, an online platform where amateur evaluators review beers while also engaging with other users. Online reviewers publicly rate and describe their impressions of a variety of beers, from craft to mainstream.

The data set included 1.66 million user-submitted reviews of American-produced beers, including 82,077 unique beers, 4,302 brewers, 47,561 reviewers and 103 unique styles of beer. The reviews spanned from December 2000 to September 2015.

When the researchers compared scores given to the same beer over time, they confirmed their hypothesis about the conditions under which evaluators contradict the majority opinion. On average, reviewers were more inclined to contradict the majority opinions for a beer that had been highly rated and widely reviewed. When reviewers considered a particular brew to be a “lowbrow,” downgrading occurred to an even greater extent.

Kim and DellaPosta’s research has implications for both producers and consumers. Both groups should be aware of the social dynamics involved in product evaluation. The research suggests that reviews and ratings are as much about elevating the people who make them as they are about product quality.

Making evaluators identifiable and non-anonymous may help increase accountability for what they say online — a seemingly positive thing. But Kim and DellaPosta reveal a potential downside: Knowing who evaluators are, Kim says, “might warp the ratings in ways that depart from true objective quality.”

Navigating corporate challenge of genuinely supporting social causes, per Rice research

Houston Voices

It is becoming more and more common for companies to promote social causes such as human rights, LGBTQ+ rights, racial justice, and environmental sustainability. But organizations face a tricky dilemma when expressing commitments to helping address social issues: Stakeholders may interpret their words and deeds as shallow rhetoric or insincere posturing.

Terms like “greenwashing” (regarding environmentalism) or “pinkwashing” (regarding LGBTQ+ rights) are on the rise, and they signal heightened suspicions around companies doing something with ostensible objectives of bringing in positive social change.

It's critical for researchers and business leaders to investigate this duality of audience perception: actual virtue versus virtue-signaling. In an age of social media and polarization, consumers are increasingly likely to wonder: Does this company have ulterior motives? Are they trying to cover for their own wrongdoing? Are they actually walking the walk, or are they merely talking the talk?

When can companies avoid such suspicion of being pro-social imposters?

Minjae Kim of Rice Business and Ezra W. Zuckerman Sivan of MIT Sloan School of Management have taken a close look at the conditions under which upholding social norms will make firms appear to be “model citizens” and when it will make them seem like imposters.

Their theory is two-fold: First, those who follow through and do social good in response to an explicit “social mandate” are viewed as “model citizens.” Second, those who go out of their way to do social good without any prompts or social mandates are less likely to be trusted and will be widely viewed as imposters.

Think about the following situation. A “social mandate” is given to a politician when they are asked in an interview what they think about a particular cause. In that context, if they express support, audiences are less likely to suspect the politician of having ulterior motives or pandering to constituents. After all, if the politician does not express support in that situation, that is tantamount to expressing disapproval. Here, the interview question (i.e., “social mandate”) provides a cover of plausible deniability to any suspicions of ulterior motives. Law enforcement (e.g., police, prosecutors) often have this social mandate built into their professions.

But if the politician takes initiative — unprompted — to support the same cause, they will more likely be viewed with suspicion. They may instead appear to seek out social rewards associated with supporting the cause (e.g., good reputation), without the cover of plausible deniability.

To test their theory, Kim and Zuckerman launched a series of experiments involving 509 online participants based in the United States. The experiments sought to determine how respondents perceive individuals who encourage others to abide by social norms. Participants were specifically asked to identify which of two individuals they think are “model citizens” committed to the norm, or “imposters” who are uncommitted but trying to hide their own deviance.

The researchers found that people who encourage others to abide by social norms when prompted (“social mandate”) are perceived as “model citizens,” while those who do the same but without such prompts are more likely to appear as “imposters.” This duality provides a clear guideline for managers engaging in corporate social responsibility: When suspicions are rampant, launching pro-social campaigns without a plausible mandate may heighten suspicion regarding motives.

The larger question is how to build firms and societies where people can safely support norms (that we all support) without being suspected as imposters. After all, we want our own norms and moral principles to govern our lives. But in some situations, we may mistakenly vilify those who are trying to do good, based on the absence of some contextual “social mandate.”

Houston research: Strong connections go a long way in job hunting

houston voices

Job hunting can feel like prying open a succession of elaborately padlocked doors, and making it through all of them might seem to require a miracle. In reality, though, you could know someone who has the right keys – and is willing to use them for you.

As layoffs and furloughs continue to transform the workplace, commentators often discuss whether job hunters are better served by a team of close friends or a wider, less intimate army of acquaintances. This discussion is especially relevant when about 20 percent of high-income workers appear to get jobs via firm-driven referral practices.

For years, research pointed toward the less intimate army. Casual acquaintances or friends-of-friends, the types of relationships known as "weak ties," seemed preferable because they offered a greater number of and more diverse job tips. Social media platforms such as LinkedIn, Facebook and other networking sites thrived on the notion that loosely connected groups were more effective networks than the concentrated energies of a few friends.

But Rice Business professor Minjae Kim and Massachusetts Institute of Technology professor Roberto M. Fernandez have taken a fresh look at the matter, questioning whether weak ties are really that useful. In a recent paper, they analyzed when and why socially connected people share job opportunities they know about.

To gather their data, the team surveyed 196 first-year MBA students, asking half of them (randomly assigned) their willingness to help close friends and the other half about acquaintances. Both close friends and acquaintances were described as qualified for the opportunities.

Past research assumed that regardless of the strength of the ties, people would be equally likely to relay job information, thus focusing on the reach of weaker, more numerous ties. But in Kim and Fernandez' study, the participants, most of whom were former professionals, said they were more likely to help friends than people with distant, weaker connections.

This was true even when the students being surveyed were offered a hypothetical financial bonus. Offering money for referrals is a time-honored practice in many industries, and indeed, when a bonus was offered, participants in the study were more willing to give a job tip to an acquaintance.

But the study also revealed that money isn't always enough to make people pass along job information, which other recent research confirms. For some people, Kim and Fernandez found, helping a good friend is more important than gaining professional or social benefit by helping a mere acquaintance.

In fact, even when an acquaintance was known to be qualified for a job, and even with referral bonuses as an incentive, when it came to passing on job tips, most participants surveyed favored close friends over people with whom they only had weak ties.

Praising the weak tie is still de rigueur in many employment think pieces. But, the team concluded, landing a job requires more than simply knowing people who know about possible job opportunities. In many cases, someone needs to make an effort for you. We all have a range of motivations, only some of them financial, for sharing information. Friendship, Kim and Fernandez discovered, is a surpassingly strong motivator for relaying job information.

Having an intricate network can be a highly effective way to learn what's out there. But because individuals have such a strong bias toward friends, big networks should not be a job hunters' lone strategy. Keeping your friends close, it turns out, offers professional benefits. The person with the key to your next job may be standing nearer than you think.

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.”

Aegis Aerospace appoints Houston space leader as new president

moving up

Houston-based Aegis Aerospace's current chief strategy officer, Matt Ondler, will take on the additional role of president on Jan. 1. Ondler will succeed Bill Hollister, who is retiring.

“Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers,” Stephanie Murphy, CEO of Aegis Aerospace, said in a news release.

Hollister guided Aegis Aerospace through expansion and innovation in his three years as president, and will continue to serve in the role of chief technology officer (CTO) for six months and focus on the company's technical and intellectual property frameworks.

"Bill has played an instrumental role in shaping the success and growth of our company, and his contributions leave an indelible mark on both our culture and our achievements," Murphy said in a news release.

Ondler has a background in space hardware development and strategic leadership in government and commercial sectors. Ondler founded subsea robots and software company Houston Mechatronics, Inc., now known as Nauticus Robotics, and also served as president, CTO and CSO during a five-year tenure at Axiom Space. He held various roles in his 25 years at NASA and was also named to the Texas Aerospace Research and Space Economy Consortium Executive Committee last year.

"I am confident that with Matt at the helm as president and Bill supporting us as CTO, we will continue to build on our strong foundation and further elevate our impact in the space industry," Murphy said in a news release. "Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers."

Rice University launches new center to study roots of Alzheimer’s and Parkinson’s

neuro research

Rice University launched its new Amyloid Mechanism and Disease Center last month, which aims to uncover the molecular origins of Alzheimer’s, Parkinson’s and other amyloid-related diseases.

The center will bring together Rice faculty in chemistry, biophysics, cell biology and biochemistry to study how protein aggregates called amyloids form, spread and harm brain cells. It will serve as the neuroscience branch of the Rice Brain Institute, which was also recently established.

The team will work to ultimately increase its understanding of amyloid processes and will collaborate with the Texas Medical Center to turn lab discoveries into real progress for patients. It will hold its launch event on Jan. 21, 2026, and hopes to eventually be a launchpad for future external research funding.

The new hub will be led by Pernilla Wittung-Stafshed, a Rice biophysicist and the Charles W. Duncan Jr.-Welch Chair in Chemistry.

“To make a real difference, we have to go all the way and find a cure,” Wittung-Stafshede said in a news release. “At Rice, with the Amyloid Mechanism and Disease Center as a catalyst, we have the people and ideas to open new doors toward solutions.”

Wittung-Stafshede, who was recruited to Rice through a Cancer Prevention and Research Institute of Texas grant this summer, has led pioneering work on how metal-binding proteins impact neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. Her most recent study, published in Advanced Science, suggests a new way of understanding how amyloids may harm cells and consume the brain’s energy molecule, ATP.

According to Alzheimer’s Disease International, neurodegenerative disease cases could reach around 78 million by 2030 and 139 million by 2050. Wittung-Stafshede’s father died of dementia several years ago.

“This is close to my heart,” Wittung-Stafshede added in the news release. “Neurodegenerative diseases such as dementia, Alzheimer’s and Parkinson’s are on the rise as people live longer, and age is the largest risk factor. It affects everyone.”
