“Idea theft,” or the appropriation of someone else’s idea, in the workplace refers to the practice whereby a person deliberately attributes to themselves the authorship of an idea, proposal, or piece of work that belongs to someone else, without giving due recognition. In other words, it is the unjustified claiming of another person’s contribution as one’s own. This often shows up in meetings or collaborative projects when an employee presents an idea that was first proposed by a colleague, receives the credit, and fails to mention the real originator. Although the phenomenon is well known in everyday business life, until recently it had not been studied as a distinct topic in the scientific literature and was usually treated as part of workplace bullying or broader toxic behaviour. More recent research, however, documents that idea theft is a distinct form of workplace misconduct and that it is particularly widespread. In studies involving more than 1,500 employees, 91% of participants reported that they had been victims, eyewitnesses, or even perpetrators of idea theft, while 87% had personally experienced having their work appropriated. This suggests that the practice occurs far more often than many would expect and constitutes a real problem for organisations. Moreover, incidents are often perceived by victims as intentional and can have significant consequences, even when the perpetrator claims there was no intent.
A key question is what kinds of people are more likely to engage in idea theft. Research in organisational psychology links certain personality traits, especially those associated with the so-called “Dark Triad,” to a higher likelihood of appropriating others’ intellectual work. Such individuals tend to show low empathy, a heightened sense of entitlement, and an instrumental view of other people, all of which facilitate unethical conduct for personal gain. Three broad profiles are commonly discussed. The first is narcissism. Narcissistic personalities are marked by an inflated ego, a need for admiration, and a sense that they “deserve everything.” In the workplace, a narcissistic person is primarily concerned with self-promotion and often has little hesitation about taking credit for others’ work in order to enhance their status. Empirical evidence indicates that people high in narcissism show weaker moral restraint and are more willing to lie, cheat, and steal compared with less narcissistic colleagues. A narcissistic employee may claim authorship of a successful idea even if it was not theirs, sincerely believing they deserve the reward. As a Cornell analysis has noted, narcissists often appropriate credit for others’ ideas and results, typically attributing success to themselves while deflecting responsibility when things go wrong.
The second profile is Machiavellianism. Machiavellians are described as highly cynical and manipulative types who operate with cold calculation to achieve their goals. An employee with Machiavellian traits is likely to view idea theft as a strategic tactic for advancement. Such individuals systematically amplify their own contribution and downplay others’, positioning themselves as the “brains” behind every team success. For example, a manager with these tendencies might present a project to senior leadership as their own achievement, omitting the fact that the original concept or the resolution of a critical problem came from a member of their team. The lack of moral constraints typical of Machiavellians, namely their willingness to deceive and exploit others for personal benefit, means they have little hesitation about appropriating colleagues’ intellectual work when they believe that “the end justifies the means.”
The third profile concerns low empathy and psychopathic tendencies. This category includes personalities marked by a pronounced lack of emotional empathy and remorse, traits often seen in individuals with psychopathic tendencies. Such employees feel little guilt when they harm others or violate rules, which makes them more prone to antisocial actions at work. Studies indicate that individuals who fall within the “Dark Triad,” narcissism, Machiavellianism, and psychopathy, are characterised by an ability to lie, mislead, and manipulate without remorse. It is therefore unsurprising that they show a greater inclination toward fraud, theft, and abuse within organisations. Research has also found that people with these dark traits are more likely to copy, falsify work, or appropriate outcomes that do not belong to them. A total lack of empathy means such individuals do not reflect on the fact that “stealing” a colleague’s idea may wrong that person or damage team morale. They see only their own benefit.
Whether idea theft will flourish or be contained within an organisation depends largely on the culture and practices promoted by leadership. Indifferent or ineffective management can, often unintentionally, allow the phenomenon to spread, whereas leadership that dares to address it directly can discourage it. According to experts, organisational culture and the norms set by management strongly shape the frequency with which idea appropriation occurs. If such behaviour is tolerated or, worse, indirectly rewarded by leadership, it becomes part of “normality” and can become so deeply embedded that it later becomes difficult to change. For example, in some highly competitive workplaces where only the final outcome matters, managers may overlook who first had the idea as long as the work gets completed. In doing so, however, they send the message that appropriating others’ work is acceptable, establishing a vicious cycle of missing recognition.
Likewise, leadership inaction or complicity leaves victims without support or voice. Many employees hesitate to report that someone “stole” their idea, especially if the perpetrator is their supervisor, for fear they will be targeted or punished for daring to claim ownership of their work. In a culture where leadership does not clearly recognise each person’s contribution, employees learn that it is pointless to complain when they are wronged. Poor management may also mean that supervisors themselves appropriate their team’s ideas. This not only constitutes direct theft of intellectual work but also creates a powerful disincentive for employees to share new proposals, because they know that in the end “the boss will take all the glory.” In other words, when leadership fails to prevent the problem, or becomes part of it, trust in the evaluation and reward system is eroded. By contrast, in organisations where leaders set an example by giving credit where it is due, idea appropriation is treated as an unacceptable deviation and is marginalised.
Idea theft is not merely an ethical lapse. It has very serious consequences for the smooth functioning and innovative capacity of a business. Since ideas and knowledge are critical resources, anything that undermines knowledge flow within an organisation can cause major harm. Researchers warn that appropriating intellectual work is a uniquely damaging form of deviant behaviour that erodes trust and employee morale, putting at risk the success of the company’s knowledge management initiatives. Put simply, when people fear their ideas will be “stolen,” they stop sharing their knowledge openly, and collaboration and innovation are blocked.
One of the most immediate effects is that victims of idea theft become cautious and protective of their work. More than half of employees who have experienced such incidents report that afterwards they avoided sharing information or knowledge, deliberately adopting silence or a defensive stance. They often choose silence in meetings, do not propose new ideas or solutions, and may even hide information and know-how, fearing that if they contribute, their authorship will be “snatched” again. These proactive defensive reactions fall under what experts call knowledge hiding and can paralyse team creativity. As Professor David Zweig describes, the experience of not receiving credit for your own idea can “burn” you and then make you unwilling to share others in the future, creating a toxic environment where information does not flow. This phenomenon “kills” the open exchange of viewpoints that is necessary for innovation, leading teams to stagnate in sterile silos rather than collaborate creatively.
At the same time, psychological safety is shaken, meaning employees’ sense that they can take risks and speak up without fear. Idea theft undermines psychological safety in two ways. First, the victim feels wronged and exposed, especially if they cannot protest. Second, everyone else observes that initiative may be punished rather than rewarded. Thus a climate forms where employees do not feel safe to share thoughts or take initiative, fearing either that their idea will be taken or that they will be labelled “difficult” if they demand recognition. This severely undermines team learning and experimentation, discouraging any behaviour beyond what is strictly prescribed.
The negative consequences do not stop there. They extend to productivity and talent retention. When employees feel that their efforts are not recognised, or worse, that others are taking them, morale drops sharply. Job satisfaction declines and many begin to disengage. They may either work less intensely, thinking “why try, since I won’t get the credit anyway,” or they may engage in retaliatory behaviours that harm team performance. Research shows that those who have been “burned” by idea theft are more likely to engage in counterproductive work behaviours, such as disparaging colleagues, refusing help, or sabotaging collaborations, in response to the injustice they experienced. In the long term, a workplace where such practices are tolerated leads to higher turnover. Capable employees, frustrated by the absence of fairness, choose to leave for healthier environments. This not only creates knowledge gaps and rehiring costs but also damages the organisation’s reputation. If it becomes known that a company does not protect creators and leaves “idea thieves” unpunished, it will struggle to attract and retain top talent. Overall, idea theft undermines innovation, lowers productivity through reduced engagement and cooperation, and destroys trust, a core component of psychological safety at work.
Given the seriousness of the issue, it is crucial that organisations take specific measures to prevent or address the appropriation of others’ intellectual work. Evidence-based practices and recommendations from studies include, first, recognising the problem and cultivating a culture of transparency. The first step is for management itself to acknowledge openly that idea theft exists and to declare zero tolerance for it. Leaders should encourage employees to speak up when they see such incidents, following the simple logic “if you see something, say something.” Creating safe channels of communication, for example anonymous reporting or open discussions in meetings, increases visibility and helps prevent cover-ups. When employees feel that management will support them if they report appropriation, they are more likely to do so, preventing the normalisation of the behaviour.
Second, there must be an emphasis on giving credit and recognition. Leaders and supervisors should actively assign credit to the right people, providing public recognition for employees’ ideas and work. As experts note, nothing kills workplace motivation more than having one’s contribution go unrecognised. Managers should therefore consciously say, for example, “this idea was proposed by team X,” or “I want to highlight A’s contribution to developing this solution.” This model of leadership accountability shapes behavioural norms and shows everyone that reward comes with a collaborative spirit and respect for intellectual authorship. Over time, such top-down behaviour reduces the likelihood that employees will hide their ideas out of fear, because they know they will receive recognition for what they contribute.
Third, a key organisational lever for change is the reward system and, in particular, favouring team rewards rather than purely individual ones. If evaluation and bonuses are based solely on individual “wins,” employees are incentivised to claim personal credit even for collective work. Experts recommend revising reward structures so that team successes and collaborative performance are rewarded. This reduces the perceived need for appropriation, because the collective outcome is shared and there is no “zero-sum game” over who gets the glory. Recent studies explicitly recommend that organisations focus more on team success than individual success in order to reduce incentives to claim exclusive recognition. In addition, when evaluations are conducted, it is helpful to request 360-degree feedback, meaning evaluation from colleagues, subordinates, and supervisors, so that it becomes clearer whether someone repeatedly absorbs others’ work or, conversely, contributes in a team-oriented way.
Fourth, documentation and idea-protection structures can be useful. Some companies adopt mechanisms to document authorship of ideas inside the organisation. For instance, an internal system may allow employees to submit new proposals with a timestamp and description. If a dispute later arises, it becomes clear who submitted the idea first. Similarly, keeping meeting minutes that record who proposed what can deter would-be thieves. While such measures do not eliminate the phenomenon on their own, they provide a level of transparency that makes appropriation harder to carry out unnoticed.
Fifth, training and role modelling matter. Organisations can invest in leadership training and awareness-building around the ethics of recognition. Managers should be trained to identify and condemn idea theft behaviours in their teams. Through seminars or workshops on psychological safety and teamwork, the value of each member and the importance of crediting ideas to the right people can be emphasised. The visibility of positive role models, for example leaders who earn respect because they always acknowledge the contributions of their teams, also works as a powerful example. Leadership should consistently demonstrate that it values originality and collaboration, not political showmanship at others’ expense.
In summary, idea theft in the workplace is a multifaceted problem. It has roots in individual characters with low ethics and high ego, but it flourishes only in environments that permit it or ignore it. Its effects are deep. It strikes innovation, erodes trust, and reduces performance. Fortunately, international research and organisational experience point the way forward. A culture of fairness and recognition, leadership that sets the right example, and structures that support cooperation are essential. With such measures, businesses can protect their most valuable asset, their people and their ideas, ensuring an environment where creativity is rewarded rather than appropriated.
