Narcissistic CEOs appoint other narcissists to the management board

This has an impact on the dynamics and stability of the team, as management boards with more narcissistic managers have a significantly higher turnover rate, which can mean sizeable costs for a company.

Narcissism manifests itself in different forms in leadership situations – from self-confidence and charisma to destructive self-focus and lack of consideration for others. While this character trait in individual CEOs is already the subject of research, very little is known so far about its impact on the wider composition of senior management.

This was the starting point for the study conducted by Professor Graf-Vlachy’s team, which analyzed LinkedIn profiles of top managers. “Narcissists want to show a broader audience that they are superior. Earlier studies have found that this is also reflected in corporate press releases or letters to shareholders, among other things,” says Professor Graf-Vlachy. Elements that are indicative of narcissism include, for example, the size of an executive’s picture in the annual report or the frequency with which a manager’s name appears in a company’s press releases.

In their study, the authors used the same approach to analyze individuals’ digital presence on social media. “We have demonstrated that we can reliably measure the narcissism of managers on the basis of their LinkedIn profiles by analyzing the number of pictures of the manager, the length of the text in the ‘About’ section, and the skills, certificates, and career steps listed,” says Professor Graf-Vlachy.

Increased fluctuation can be expensive for companies

In total, the team analyzed 11,705 LinkedIn profiles of top managers of US companies. The study reveals an astonishing tendency: CEOs with a higher degree of narcissism appoint members to their management board who mirror their own character traits – in other words, who also display a narcissistic streak. An increase in the narcissism of a CEO by one standard deviation leads to an 18 percent higher level of narcissism in each newly appointed executive.

This also has an impact on the dynamics and stability of the team, as management boards with more narcissistic managers have a significantly higher turnover rate, which can mean sizeable costs for a company. “Narcissists want to dominate each other, which leads to conflicts on the board, and these in turn lead to more fluctuation in the executive team,” summarizes Professor Graf-Vlachy.

“The results of the study show that it is important for CEOs and supervisory boards to understand the dynamics in their executive teams better and to review the selection process for managers,” the researchers conclude. “This can be achieved if the personality traits of managers are also viewed in a balanced way.”

Want entrepreneurs to work harder? Tell them they’ll fail

Most entrepreneurs – people who start their own businesses – actually identify with the business they’re running. So being told that your business, your idea that you are committed to, will be a failure can almost seem like a personal attack.

A new study finds entrepreneurs become more committed to their business ventures when they are told they will fail, increasing their efforts to make those businesses successful.

“Most entrepreneurs – people who start their own businesses – actually identify with the business they’re running,” says Tim Michaelis, corresponding author of a paper on the work and an assistant professor of psychology at North Carolina State University. “So being told that your business, your idea that you are committed to, will be a failure can almost seem like a personal attack.”

“We wanted to see if being told that their business will fail actually gets entrepreneurs to commit even more deeply,” Michaelis says. “We were somewhat surprised that researchers had not already examined this. Most of the literature in this area is from the field of developmental psychology and hadn’t explored potential business implications. Fundamentally, we wanted to know if having an underdog mentality can motivate entrepreneurs.”

To explore the subject, the researchers conducted three studies.

For the first study, the researchers recruited 423 entrepreneurs; of those, 213 were in a control group that was not asked about a time they had been told they would fail. One hundred and seven participants were asked about, but could not recall, a time they were told they would fail. The remaining 103 participants did recall a time they were told they would fail. The researchers then asked all study participants questions designed to capture how committed they were to persisting with their new businesses.

“We found that entrepreneurs who could recall being told their business would fail displayed a deeper commitment to persisting with their business ventures,” Michaelis says.

For the second study, the researchers worked with 579 entrepreneurs. In this study, the control group consisted of 289 participants; 234 participants couldn’t remember being told they would fail; and 56 could recall a time they were told they would fail.

This time the researchers essentially replicated the first study, but rather than asking questions designed to measure persistence, they asked questions designed to measure the extent to which study participants were motivated to prove someone wrong. The 56 participants who could recall being told they would fail were asked about their motivation to prove that specific naysayer wrong – the so-called “underdog effect.” The remaining study participants were simply asked about their motivation to prove something to general stakeholders.

“The results here were consistent with the first study – recalling a time when someone told them they would fail led to increased motivation to persist with their business venture,” says Michaelis.

For study three, the researchers recruited 417 entrepreneurs. The study participants were surveyed once per month for three months. The first month’s survey served to establish a baseline, measuring the extent to which each study participant was motivated to persist with their venture by the underdog effect – a desire to prove any doubters wrong.

The second and third surveys varied slightly, but were essentially designed to assess the extent to which motivation and persistence were driven by the underdog effect. The surveys also accounted for other variables associated with motivation and persistence, such as confidence, past experience, financial benefit and passion for the work.

“The third study reinforced what we found in studies one and two – the underdog effect is a powerful motivator that increases an entrepreneur’s motivation and persistence regarding their venture,” says Michaelis. “In other words, the underdog effect leads to people working harder, focusing on their venture, and really committing to the success of their business.”

But the studies also revealed something unexpected.

“There were a surprisingly large number of study participants who had never been told that they would fail – they had only ever received positive feedback, or possibly no feedback, about their business ideas,” says Michaelis. “And we found that those study participants were less committed to their business ideas and had lower levels of persistence.

“This work offers real insight into what motivates entrepreneurs, and it raises some interesting questions,” says Michaelis.

“How do you give entrepreneurs enough support to encourage their initiative, but enough resistance to help them develop the drive they need to succeed? How can we train entrepreneurs to distinguish between doubts that can serve as motivational fuel and constructive criticism that highlights real flaws in a business plan? These are issues we can explore moving forward.”

The paper, “I’ll prove you wrong! The underdog effect as an antecedent to entrepreneurial action and venture persistence,” is published in the Journal of Business Venturing. The paper was co-authored by Jeffrey Pollack, the Lynn T. Clark II Distinguished Professor of Entrepreneurship in NC State’s Poole College of Management; Jon Carr, the Jenkins Distinguished Professor of Entrepreneurship in NC State’s Poole College of Management; April Spivack of the Hanken School of Economics in Finland; Nicholas Smith of Northern Illinois University; and Alexander McKelvie of Syracuse University.

Study shows scaling startups risk increasing gender gaps

Founders with HR‑related education counteract these challenges. In ventures led by founders with HR training, the odds of hiring a woman increase by more than 30 percent, and the odds of appointing a woman to a managerial role increase by 14 percent for the same level of scaling.

When startups scale quickly, founders often make hurried hiring decisions that unintentionally disadvantage women, according to new study from the Stockholm School of Economics in Sweden. The study shows how the pressures of rapid growth increase the likelihood that founders rely on mental shortcuts and make biased decisions. 

Drawing on large‑scale Swedish data, the study shows that scaling—when companies hire far more people than their usual growth trend would predict—puts pressure on founders to decide swiftly, which increases the use of mental shortcuts. These shortcuts can activate gender stereotypes, shaping who gets hired and who moves into managerial roles.  

“During those moments of rapid growth, even well‑intentioned leaders can fall back on familiar stereotypes when assessing who they believe is best suited for the role,” says Mohamed Genedy, co-author and Postdoctoral Fellow at the House of Innovation, Stockholm School of Economics. 

Reduced odds of hiring female managers 

His research analyzes more than 31,000 new ventures founded in Sweden between 2004 and 2018. It finds that in male‑led startups, scaling reduces the odds of hiring a woman by about 18 percent, and the odds of appointing a woman to a managerial position by 22 percent.  

These patterns emerge even in a highly gender‑equal national context, making the findings especially noteworthy.  

Crucially, the study reveals that founders with HR‑related education counteract these challenges. In ventures led by founders with HR training, the odds of hiring a woman increase by more than 30 percent, and the odds of appointing a woman to a managerial role increase by 14 percent for the same level of scaling.  

“When founders have experience with structured hiring practices, the gender gaps shrink, and in some cases even reverse,” Genedy says.  

“This shows that getting the basics of HR right early on really pays off. When things start moving fast, founders with HR knowledge are less likely to rely on biased instincts and more likely to hire from a broader talent pool.”  

Prior experience in companies with established HR practices also helps, though less so. It raises the likelihood of hiring women as the new ventures scale, but does not significantly affect managerial appointments. 

Differences persist in female-led ventures 

The study additionally shows that these patterns are not driven by founder gender alone. Even solo female‑led ventures display similar tendencies when scaling, though to a somewhat lesser degree.  

And in female‑dominated industries, scaling increases the hiring of women for regular roles but still reduces the likelihood that women are appointed into managerial positions.  

“When scaling accelerates, cognitive bias kicks in for everyone,” says Mohamed Genedy. “Female founders are not immune to these patterns.”  

Together, these results point to underlying cognitive mechanisms that shape decisions under time pressure.

The study, Scaling with Bias? The role of founders’ HR knowledge and experience in hiring and managerial appointments, was published in Human Resource Management.

Retail therapy fail? Online shopping linked to stress, says study

Online shopping is more strongly linked to stress than reading the news, checking your inbox or watching adult entertainment. This is something online businesses should know and consider.

Published

Planning to save time by doing your shopping online? If so, it’s possible you’re not doing your well-being any favours. A study from Aalto University in Finland has found that online shopping is more strongly linked to stress than reading the news, checking your inbox or watching adult entertainment. The internet can be both a source and a reliever of stress though, according to research –– so do we scroll because we’re stressed, or are we stressed because we scroll?

It’s a complex problem to unravel, according to doctoral researcher Mohammed Belal.

‘Previous studies have shown that social media and online shopping are often used to relieve stress. However, our results show that a rise in social media use or online shopping is linked to an increase in self-reported stress across multiple user groups and across devices,’ he says.

The study found that users of YouTube and streaming services, as well as online gamers, also reported increased stress levels. For people experiencing high-stress, time spent on social media was twice more likely to be linked to stress as compared to time spent on gaming. Meanwhile, across many user groups, those who spent more time reading emails and news, or watching adult entertainment, reported lower stress-levels –– although the researchers note that they looked only at the time spent on news sites, not their content.

‘Somewhat surprisingly, people who spent a lot of time on news sites reported less stress than others. On the other hand, those who already experienced a lot of stress didn’t spend much time on news sites –– and that’s consistent with previous research that shows that stress can reduce news consumption,’ Belal says.

Overall, the study found a strong connection between internet use, in general, and heightened stress, especially among those who already experienced a lot of stress in daily life. Women reported more stress than men, and the older and wealthier the participant, the less stress they experienced. The de-stressing effect of adult entertainment may be explained by the fact that it was usually consumed in small doses, acting as a short-term stress or boredom reliever.

The study, to be published in the Journal of Medical Internet Research on 9 January 2026, recorded the internet usage of nearly 1,500 adults over a seven-month period. After that, data from nearly 47 million web visits and 14 million app usages was combined with users’ self-reported stress.

Issues commonly discussed, yet not well understood

The research comes at a time when the effects of social media on well-being are under increasing scrutiny. For example, a recent ban in Australia on social media for children has the rest of the world watching closely. Yet despite the increasing influence of the internet on our lives, our scientific understanding of the impacts of its use on well-being is remarkably limited, says Belal.

‘It leaves a huge critical gap in understanding how online behaviors impact stress and well-being,’ Belal points out.

With the aim of closing this gap, the study is among the first to use a tracking programme installed on users’ devices, rather than asking subjects to self-report their usage, explains assistant professor Juhi Kulshrestha. The long duration and large sample size of the research also make the findings particularly significant.

However, she points out that further research is needed to disentangle the relationship between stress and well-being and internet usage.

‘Are people more stressed because they are spending more time online shopping or on social media, or are such sites offering them an important support in times of duress? It’s really crucial that we study these issues further so we can solve that chicken and egg problem,’ says Kulshrestha. ‘Putting a blanket ban or upper limits on certain kinds of internet usage may not actually end up solving the issues, and could even take away a vital support for people who are struggling.’

Either way, the researchers see practical applications for the results in the development of well-being and online services. In future, they plan to examine the consumption of different types of news, such as political, entertainment, or sports news, and how it relates to stress and other well-being variables. The hope is that better data will lead to helping internet users maintain a healthy balance.

‘As we gain increasingly accurate information about people’s internet usage, it will be possible to design new kinds of tools that people can use to regulate their browsing and improve their well-being,’ says Kulshrestha.
