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.

Rice student startup lands $1.85M to launch medical drone network

critical cargo

Students at Rice University have developed a medical cargo drone transport system to help deliver sensitive medical supplies and improve mobile healthcare efforts.

Haast Autonomous is the brainchild of graduating seniors Ege Halac, Jason Chen and Santiago Brent, who got their venture idea off the ground with help from the Liu Idea Lab for Innovation and Entrepreneurship (Lilie) Summer Venture Studio. The founders have developed the prototype at Rice’s Oshman Engineering Design Kitchen (OEDK) with fellow Rice researchers Felix Hasson, Ethan Javedan, Kenna Sanders and Caden Schmidt.

The startup has raised $1.85 million in pre-seed funding, according to Rice. The founders plan to focus on Haast full-time following graduation. They said they aim to launch pilot trials in 2027 and head to market later that year.

“We need better alternatives for a fast, safe and on-demand system of transport for life-critical cargo,” Halac said in a news release from Rice.

The Haast team has developed a custom aircraft with software that manages dispatch, routes, and chain of custody to assist in how materials move between sites in centralized medical systems. Generally, the transportation of medical supplies and materials between facilities and points of care relies on ground shipping or expensive air transport.

Haast Autonomous’ aircraft can take off and land vertically, and is designed around a mission profile of 50 to 62 miles. It can carry a payload of at least 5 pounds, with future versions intended to scale up in size. It also includes a built-in payload bay that regulates temperature, pressure, vibration and tilt to protect sensitive contents such as patient samples, antivenom or poisoning kits and radioligands or other therapies, according to Rice.

At first, the company envisioned the mission to be centered around transplants, but saw the product being best suited for a variety of operations.

“What we realized is that the platform we are building is suited for medicine, but it really underlies a much larger problem of mission-critical transport across industries,” Brent added in the news release. “We are building the fastest, most secure logistics chain for the world’s most sensitive cargo.”

Haast Autonomous was recognized at the 2026 Oshman Engineering Design Showcase and Competition, where it won Best Aerospace or Transportation Technology. It also performed well in the 2026 Napier Rice Launch Challenge.

In the future, Haast Autonomous plans to deploy a fleet of aircraft. The software will be designed to assist hospitals in requesting flights and tracking deliveries in real time.

“The drone is only part of the solution,” Chen also added in the release. “What matters is moving something from point A to point B in a way that fits into how hospitals already operate.”

Houston scientist wins prestigious Pew Scholar award for brain cancer research

standout scholar

Christina Tringides, an assistant professor of materials science and nanoengineering at Rice University, is one of 21 scientists to win a prestigious Pew Biomedical Scholar award.

She is the first faculty member from Rice to win the distinction, which provides $300,000 over four years for advances in biomedicine, according to the university. The awards are granted to researchers who are in the first few years at the assistant professor level.

In Tringides’ case, the funding will support her innovative new method of modeling glioblastoma, a common and extremely aggressive form of brain cancer. Thanks to producing its own blood supply, glioblastoma spreads quickly, weaving tendrils of blighted tissue throughout the brain. Because of this, surgery is difficult and conventional therapies ineffective.

Understanding the way glioblastoma spreads is crucial to the search for a cure. Tringides is using hydrogels that mimic the brain’s extracellular matrix. Using cultures and a microscopic labyrinth, her team can see how the cancer spreads, bonds with neurons and changes cell wall activity. Essentially, Tringides has devised an intelligence test for tumors in hopes of learning how to outsmart them.

“As cancer crawls through the maze, we can look at how it is interacting with the neurons more and more, and measure how electrical activity is changing as a result,” she said in a news release from Rice.

Examining how cancer cells grow can reveal which conditional changes slow them down. Finding ways to alter the structure of brain matter in a way that makes it inhospitable to the cancer could lead to therapies that would impede growth or even reverse it. Using her custom-made ersatz brain maze makes it easier to observe changes than it would be in a patient’s brain.

“Imaging synapses is time-intensive ⎯ it can involve large data files that are hard to visualize, but if we know that the only place where we might have a synapse is this tiny 1-by-4-by-10 micron channel, it makes it much faster and reliable to image them,” Tringides said.

Born in Ames, Iowa, Tringides received her doctorate in biophysics from Harvard before joining Rice in 2024 through a Cancer Prevention and Research Institute of Texas (CPRIT) recruitment award.

Her research was also one of the first four projects to receive research awards through the Rice Brain Institute and TMC Neuro Collaboration Seed Grant Program.

Texas residents earn 11th highest income in U.S., says 2026 study

Money Matters

A new WalletHub study comparing income disparities across America has ranked Texas residents No. 11 on the list of states with the highest earning residents in the nation.

The report, "States Where People Have the Highest Income (2026)," analyzed U.S. Census Bureau income data in all 50 states and the District of Columbia. The report evaluated the average annual income of the top five percent, the median annual household income, and the average annual income of the bottom 20 percent of residents in every state, all adjusted for the cost of living.

The report's data revealed the top five percent of Texans, the highest earners, make $520,378 on average yearly after adjusting for the cost of living. That's the seventh-highest income among the top five percent of earners nationwide.

Meanwhile, the median annual income of a Texas household is just under $76,000. The bottom 20 percent of Texas residents make $17,651 a year, the report found.

For additional context, the latest data from the Federal Reserve shows an American household's median yearly income is about $83,700. WalletHub analyst Chip Lupo also found that the highest earning 10 percent of individuals in the U.S. earn over 12 times more than those in the lowest-earning 10 percent, based on the latest Census data.

"By measuring the income of various percentiles against a state's median income, we can better identify where income disparities are more prevalent, which could help us better understand why residents of certain states struggle more to make ends meet," said Lupo.

Virginia is the state where residents earn the highest income in the U.S., WalletHub said. Based on the report's findings, the top five percent of Virginians make $545,097 on average per year after adjusting for the cost of living. The median annual income of a Virginia household comes out to $95,339, and the bottom 20 percent of residents make $19,671 annually on average.

Conversely, West Virginia is the state where people have the lowest income in the U.S. A West Virginia household makes a median annual income of $56,610, the third-lowest nationally, and the bottom 20 percent of residents make $13,260 on average per year, which is the fifth-lowest in the nation. The top five percent of West Virginians make $372,218 on average per year.

The top 10 states where residents have the highest income are:

  • No. 1 – Virginia
  • No. 2 – New York
  • No. 3 – New Jersey
  • No. 4 – Washington
  • No. 5 – Connecticut
  • No. 6 – Utah
  • No. 7 – Colorado
  • No. 8 – Minnesota
  • No. 9 – Illinois
  • No. 10 – Massachusetts
