Time plays a key role in consumer behavior, especially concerning the purchasing patterns of vulnerable groups in society who have been ridiculed in offensive and discriminatory ads. Ben-Gurion University researcher Dr. Enav Friedmann examined the long-term reactions of consumers from discriminated groups after exposure to offensive advertising. Such advertising often manifests in marketing messages that demean excluded groups, reinforce harmful stereotypes, or cross social norms.
Their findings were published last month in Psychology & Marketing. Dr. Friedmann is a member of the Department of Business Administration at Ben-Gurion University of the Negev. She is the head of the LBM research lab, which focuses on marketing,
“The social and psychological implications of such advertisements are profound,” explains Dr. Friedmann. “Socially, they normalize prejudice, perpetuate stereotypes, and undermine efforts to achieve equality. We decided to examine these conflicts of social identity combined with consumer behavior. This is a topic that hasn’t been researched enough, but it has significant implications for individuals, groups, and businesses in society.”
The Study’s Approach
To this end, three independent experiments were conducted. They examined the impact of exposure to insulting advertisements or those excluding vulnerable groups (women and people of color) at two time points: immediately upon exposure to the ad, and then 10 days or a month later.
The offensive ads were designed to be inspired by authentic advertisements from companies, which contained offensive content toward women and people of color. A total of 640 women and men, both light-skinned and dark-skinned, participated in all the experiments and answered questions related to the brand and their personal feelings.
Key Findings
In the first experiment, a hypothetical ad for a body soap brand called “BubbleSoap” was presented, with a racist implication toward people of color. A dark-skinned family was shown in the ‘before’ image and a light-skinned family in the ‘after’ image. It was found that dark-skinned participants who felt their ethnic group was severely discriminated against, and tended to identify less with their group, showed a higher purchase intention for the BubbleSoap brand ten days later compared to participants who did not feel their ethnic group was discriminated against.
The second experiment involved an offensive advertisement toward women for a real brand. Participants were randomly exposed to either non-offensive sexist ads or offensive sexist ads. The offensive version was identical but included the text: “Women, I’m sick of you! I get tired of all of you so quickly,” with the well-known tagline below: “You’re not you when you’re hungry.” This ad was inspired by real candy bar ads that mock the idea of men respecting women and aggressively disparage women under the guise of sarcastic humor.
After about a month, it was found that women who identified their gender group as significantly discriminated against, and tended to identify less with the female group, were more likely to choose the brand that offended their group. The choice was made at each time point by choosing between three chocolate brands. Of course, the respondents’ initial preference for the offensive brand was considered.
In the third experiment, neurological measurements were taken using an EEG device in a lab experiment for a construction company. Participants were randomly exposed to either offensive or non-offensive sexist ads. The offensive version included the text: “She thinks she understands… In big decisions, don’t let her decide!” Participants were asked to describe their feelings toward the brand at two points in time. The researchers measured the activation of the participants’ right and left frontal brain regions during a brand feeling task. After ten days, among women who identified their group as significantly discriminated against, and tended to identify less with the female group over time, increased activity was found in the left frontal areas (compared to the right) of the brain. These areas are known in the literature to indicate a desire to approach a stimulus.

The Paradoxical Phenomenon
The findings revealed a paradoxical phenomenon: participants who reported high levels of perceived discrimination against their group, and over time tended to identify less with the offended group, actually showed an increasing preference for the brand that insulted their group. This was measured through purchase intention, actual product choice, or brain responses indicating an approach toward the brand.
This phenomenon aligns with theories of disidentification, a process in which individuals from vulnerable groups come to understand the long-term consequences of harm to their group (reduced self-esteem and group-esteem).
Those who feel their group is significantly discriminated against and tend to reduce their identification with the group in order to protect their sense of self-esteem, tend to do so by approaching the object that harmed their group over time.
“The research findings deepen our understanding of how identity threats affect responses in advertising contexts and highlight the ethical considerations brands must address when formulating campaigns,” explains Dr. Friedmann. “This research delves into the psychological complexity of identity regulation as a result of exposure to threatening content for consumers.”
Implications and Recommendations
The study results do not suggest that offensive-discriminatory advertising is an effective marketing strategy. Most participants exposed to this content did not demonstrate more positive attitudes or behaviors than those in the control group; rather, it was a specific limited group of people who reacted positively to it. On the contrary, such advertisements can exact a significant psychological toll on individuals belonging to discriminated groups. These findings reinforce the importance of adopting an ethical approach to identity-based marketing and avoiding tactics that exploit social vulnerability for strategic profit.
In accordance with the study’s findings, the researchers recommend adopting an approach that involves enforcement and clear criteria to prevent harm to various population groups.
“Enforcement against offensive and discriminatory marketing is essential to protect the well-being of individuals and foster a more egalitarian society. As a society, we must develop specific criteria for controlling offensive advertisements, as is customary in the UK, and impose significant financial penalties on those who violate them,” concluded Dr. Friedmann.

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.

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.
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.
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.
