You've just been named CEO of a Fortune 500 company. Your ego fills the room. The laws of gravity don't apply to you.

And naturally, you want to make an impact. So you pour money into mergers and acquisitions, and when you're not trying to acquire another firm, you guide company resources into research and development. You're a genius, and the world will soon be clinging to your every new product.

The only problem: your company will likely underperform. Research by former Rice Business visiting professor Sean Wang (now at Cox School of Business as SMU), along with Nicholas Seybert of the University of Maryland and Charles Ham of Washington University at St. Louis, reveals the high costs of an out of control CEO ego.

The researchers' first challenge was establishing who could legitimately be called a narcissist. What does the term mean, exactly? While there are varying definitions, Wang's team focused on narcissism as a basic personality trait rather than a mental illness. As a personality trait, narcissism is associated with entitlement, vanity, authority, and a sense of superiority.

To spot narcissists, the team took a novel approach: they examined their research subjects' signatures. Signature size turns out to be a handy measure for egos, because it doesn't require participants to answer direct questions about their personalities — and because participants are unlikely to know that ego can affect something as simple as a signature.

Just having a big ego, though, does not a narcissist make. To validate a link between a person's signature and narcissism, the researchers asked 53 graduate business students to provide their signatures by signing a document, and then to take a personality survey that measured narcissism. The findings documented that indeed there was a strong correlation between signature size and narcissism.

Next, the researchers obtained data from prior psychology research on employee perceptions of 32 technology-firm CEOs. Of the 24 CEOS for whom the researchers also had signature samples, they found a significant correlation between narcissism and signature size.

Armed with these findings, Wang and his colleagues were able to extrapolate the narcissistic traits of thousands of CEOs whose signatures were readily available on proxy statements and other corporate documents. The researchers ultimately studied 741 CEOs from 411 firms during the period between 1992 and 2015, corresponding to 6,361 firm-year observations with a median of eight fiscal years per CEO.

They found a pronounced behavior pattern. Firms led by narcissistic CEOs invested more in high-exposure areas such as research and development and mergers and acquisitions, but shied away from routine capital expenditures for day-to-day productivity. This trend was even more pronounced during periods of financial slack, suggesting that narcissistic CEOs prefer an aggressive management style whenever possible. Financial productivity delivered by these narcissistic CEOs in terms of profitability was lower than their less egotistic counterparts.

The research has multiple implications. Narcissistic leaders, past research shows, are prone to make bad decisions — in part because they are bad listeners. As a result, they often dominate the decision process without incorporating feedback or ideas from others. Ironically, they mistakenly perceive this behavior as a signal of competence and strong leadership.

To counter these bad habits, the researchers say, during periods of financial sluggishness investors and corporate boards should combat excessive narcissist-led investment by pushing for higher dividend payouts. Given that narcissistic CEOs overinvest in R&D, investors also need to closely monitor whether such investments represent real innovation or just vanity. Finally, boards of directors should be aware that narcissistic leaders tend to command higher salaries — and consider whether their CEO falls into this category, and is essentially getting higher pay for inferior performance.

In short, to really be as boss as they see themselves, narcissistic corporate leaders need to recognize their tendencies and rigorously check their egos. Boards, meanwhile, should closely monitor their CEO's priorities in directing firm resources. It could be the writing on the wall.

Rice University launches AI initiative, plans to hire 75 faculty

ai expansion

Houston’s Rice University announced a university-wide artificial intelligence initiative this week that includes hiring 75 new AI-focused faculty. It also shared new details about its planned state-of-the-art facility, The Arc.

Fresh off the announcement of Rice’s new Master of Artificial Intelligence (MAI) coming next fall, the university shared that it plans to expand its AI-related courses and be a “global leader in advanced computing and responsible AI.”

Rice reports that it has already hired 35 faculty members to deepen expertise across schools and departments regarding AI, and plans to recruit 40 more across disciplines including engineering, computing, health, energy, environmental resilience, business, humanities and the arts.

Rice's schools and departments have identified the four cluster areas to guide its hiring:

  • Foundational AI
  • AI for Health
  • AI for Energy, the Environment and Resiliency
  • Responsible AI: Society and Ethics

“Hiring exceptional faculty is essential, but it is only one part of the equation,” Amy Dittmar, Rice’s Howard R. Hughes Provost and executive vice president for academic affairs, said in a news release. “We are building the people, places and partnerships needed to advance AI from foundational discovery to societal impact.”

Another major component of the effort is the planned 200,000-square-foot facility, The Arc, which Rice announced will break ground this fall. Rice will occupy nearly 80,000 square feet of office and laboratory space dedicated to topics including AI, data science, robotics, computational engineering and energy. The university previously announced that The Arc would be completed in Q1 2028.

The Arc will also house the AI Foundry, which is being developed as a collaborative space for industry partners, scientists and students.

“As Rice grows, we are being intentional about where we invest and how we build,” Rice President Reginald DesRoches added in the release. “By bringing together exceptional faculty, a strong interdisciplinary research community, world-class facilities and Houston’s extraordinary innovation ecosystem, Rice has an opportunity not simply to participate in the AI revolution but to help define its future.”

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.
