Academic research about online disinhibition, anonymity, and online harms

Updated: Oct 23, 2019

Clean up the Internet’s thinking about online anonymity, and the role its misuse plays in undermining online discourse, is informed by a wide range of academic research. Below is a non-exhaustive list of academic works exploring the relationship between anonymity, online disinhibition, and online harms such as trolling, abuse, and bullying. We make an attempt to summarise each piece, and include some short quotes.

We’d hugely welcome other relevant research being brought to our attention.



“The Online Disinhibition Effect”

John Suler

CyberPsychology & Behavior 7, no. 3 (2004): 321

https://pdfs.semanticscholar.org/c70a/ae3be9d370ca1520db5edb2b326e3c2f91b0.pdf

This oft-cited article is an influential attempt to theorise “Online Disinhibition”, or the phenomenon of people feeling able to behave and interact differently from behind their keyboards.


Suler draws an important distinction between “benign online disinhibition” and “toxic online disinhibition”. Benign forms of disinhibition enable an individual to explore and share thoughts, emotions, and ideas in ways which have a positive or even therapeutic effect. An example might be an individual feeling able to explore an aspect of sexual identity free from the judgement of family members. Toxic forms of disinhibition involve an individual feeling able to misbehave, and able to avoid responsibility for their misbehaviour. Examples would be trolling, bullying and abuse.

Suler identifies anonymity as “one of the principle factors” behind online disinhibition.


"This anonymity is one of the principle factors that creates the disinhibition effect. When people have the opportunity to separate their actions online from their in-person lifestyle and identity, they feel less vulnerable about self-disclosing and acting out. Whatever they say or do can’t be directly linked to the rest of their lives. In a process of dissociation, they don’t have to own their behavior by acknowledging it within the full context of an integrated online/offline identity. The online self becomes a compartmentalized self. In the case of expressed hostilities or other deviant actions, the person can avert responsibility for those behaviors, almost as if superego restrictions and moral cognitive processes have been temporarily suspended from the online psyche. In fact, people might even convince themselves that those online behaviors 'aren’t me at all.'”

This study, conducted in Israel, explored the role of anonymity in “flaming” behaviour over Microsoft messenger. It sought to break online anonymity down into constituent parts and explore the relationship between them: non-disclosure of personal details, invisibility, and absence of eye-contact. Different paired conversations were set up over msn messenger with different variables e.g. cameras positioned in different places, personal details shared or concealed.

It found that single biggest factor increasing the likelihood of flaming was a lack of eye contact. They also found that not being identified by personal detail made the effects of lack of eye contact worse. The authors conclude that the experience of “anonymity online”, which leads to toxic disinhibition, is made up of a few factors, which they suggest calling an “online sense of unidentifiability”.


“To reconcile the prevailing definition of the general and quite obscure term of ‘‘anonymity’’ as used in the context of virtual reality, a more comprehensive definition is apparently required. The present findings suggest that one can think of anonymity as an assemblage of different levels of online unidentifiability, in which non-disclosure of personal details, invisibility, and absence of eye-contact compose the most significant assemblage; these components appear to combine in different degrees, thus yielding a variety of ‘‘anonymities.’’ The new concept we refer to—online sense of unidentifiability— can be understood as spanning a range, in which three major factors are considered: one end of this range is characterized by a lack of personal information (i.e., anonymity), lack of visibility, and lack of eye-contact; the other end, by disclosure of personal data, visibility, and eye-contact.
"The current findings suggest that previous definitions of anonymity did not take into account all the factors that characterize the online communication environment, specifically invisibility and absence of eye-contact. Thus, it seems advisable that future studies define the online social setting carefully and precisely so that the effects of anonymity on the behavior of communicants in cyberspace can be evaluated alongside the effects of other online situational variables. First and foremost, it is advisable that the presence of eye-contact (or its absence) between communicants be assessed in future studies of online disinhibition. It also appears that the term anonymity, as we know it, has not yet been adapted to the parameters of the new virtual reality. Henceforth, studies that include the anonymity variable should consider the broader definition the online sense of unidentifiability: non-disclosure of personal details, invisibility, and absence of eye-contact.”


“Virtuous or Vitriolic: The effect of anonymity on civility in online newspaper reader comment boards”

This study compares the levels of incivility in online comments about articles relating to immigration across a range of newspaper websites. It investigates whether there is a difference in levels of incivility where newspapers allow anonymous users to post comments, compared to those using a Facebook plugin to require users to share their Facebook identity.

The study found a significant difference between the levels of incivility, including expressions of racism, on sites where total anonymity was permitted and those requiring Facebook verification.


“Anonymous commenters were significantly more likely to register their opinion in with an uncivil comment than non-anonymous commenters. Just over 53% of the anonymous comments were uncivil, while 28.7% of the non-anonymous comments were uncivil.”

The study noted that the Facebook plugin was not the most rigorous form of identity verification – at this time around 8% of Facebook accounts were thought to be inauthentic or using a false name. The study also did not find that the restrictions on anonymity afforded by the Facebook plugin came anywhere close to eliminating anonymity altogether.


“While most of the comments in the non-anonymous forums were civil, meaning that removing anonymity was a successful strategy for cutting down on the level on uncivil comment, it by no means eliminated incivility altogether.

The study concludes that restrictions on anonymity could play a significant role in tackling incivility in online newspaper forums.


“The ways people express themselves online is significantly dependent on whether their true identity is intact, suggesting not just a correlation between anonymity and incivility but also causation. As such, commenting forums of newspaper which disallow anonymity show more civility than those that allow it. These findings should be of interest to those newspapers that allow anonymity and that have expressed frustration with rampant incivility and ad hominem attacks in their commenting forums”


Digital Social Norm Enforcement: Online Firestorms in Social Media

Katja Rost, Lea Stahel, Bruno S. Frey

This study looks at comments left on petitions on a German petition platform, openpetition.de, which offers a service similar to change.org in the UK or USA.


It introduces social norm theory in attempt to understand online aggression in a social-political online setting, "challenging the popular assumption that online anonymity is one of the principle factors that promotes aggression".

Their analysis of over half a million comments left on 1,612 petitions over 3 years, suggest that non-anonymous individuals are more aggressive compared to anonymous individuals.


They argue that this is because a major motivation of uncivil commenters is a "sanctioning of (perceived) norm violations". The commenters therefore see themselves as "norm-enforcers", are deliberately and intentionally using strong language, and wish to attach their name to it to add weight to the sanction.


"According to social norm theory, in social media, individuals mostly use aggressive word-of-mouth propagation to criticize the behavior of public actors. As people enforce social norms and promote public goods, it is most likely that they perceive the behavior of the accused public actors as driven by lower-order moral ideals and principles while that they perceive their own behavior as driven by higher-order moral ideals and principles. From this point of view there is no need to hide their identity."

The authors note some of the ways in which an online petition platform may not be typical of other social media interactions. In particular, they note that it is a specifically "social-political online setting", that the commenters are "intrinsically motivated", that the petitions are “protests” and the signers could equally be described as "protesters".


It's worth noting that no distinction is made in this study between uncivil comments made about a third party petition “target” (e.g. a politician who is perceived to be corrupt), who is not present in the conversation and presumably not expected to read it, and uncivil comments directed at other participants with a possibility that they will read it and be affected by it. Indeed, the comments cited in this study as examples of incivility and aggression are criticisms *about* politicians whom the commenter disapproves of, but are not directed *at* them:


"Exemplarily, we present three of the most aggressive comments by non-anonymous commenters: “Silly, fake, inhuman and degrading, racist, defamatory and ugly theses like those of Sarrazin (author's note: a former German politician) have no place in this world, let alone in the SPD (author's note: Social democratic party). Sarrazin certainly has no business in the Social democratic party and should try his luck with the Nazis” (ID352216); “HC Strache (author's note: Austrian politician) has an evil, inhuman character, he lies and tries to persuade other people of wrong ideas.” (ID284846); “These authorities are mostly no people, but §§§- and regulatory machines! I detest authorities–with my 67 years’ life experience after all!” (ID418089)."

Perpetuating online sexism offline: Anonymity, interactivity, and the effects of sexist hashtags on social media

This experiment investigated whether users’ anonymity and level of interactivity with sexist content on social media influenced sexist attitudes and offline behaviour. Participants were given either a Twitter account that was anonymous or one that had personally identifying details. They were told they were taking part in an experiment about online humour and were asked to share or write posts including a number which incorporated a sexist hashtag. Anonymous participants were found to be more willing to share and compose sexist material.

After exposure, participants completed two purportedly unrelated tasks, to test whether their online behaviour had any lasting impact on their attitudes - a survey and a job hiring simulation in which they evaluated male and female candidates’ resumés. Anonymous participants reported greater hostile sexism after tweeting than non-anonymous participants. Participants who composed sexist tweets reported greater hostile sexism and ranked female job candidates as less competent than those who retweeted, although this did not significantly affect their likelihood to hire.


“Given the recent attention to the exclusion of women and sexual harassment online, it is interesting to note that our findings demonstrate that anonymity promotes higher levels of sexism. In a misogynistic online climate, anonymity may be the disinhibiting factor that leads to harassment and even the extreme death threats directed at prominent women in tech such as Anita Sarkeesian, Brianna Wu, and Zoe Quinn. Further our findings indicate that what happens online does not stay online. Anonymous online sexism is harmful not just in the moment of engagement, but also leads to more sexist attitudes afterwards than when the user is identifiable”

Civility and trust on Social media

Also summarised helpfully by two of the study authors in this much shorter blog post:

https://blogs.lse.ac.uk/usappblog/2019/03/30/locking-horns-online-incivility-is-seen-as-the-new-normal-and-it-inhibits-social-trust/

This experiment investigated the impact that participants’ experiences of civility and incivility, in an online discussion on a controversial topic, had upon their subsequent behaviour and levels of trust. One group were given four genuine threads of uncivil discussion to engage with. Another group read similar threads in which uncivil discussions had been replaced with polite interactions on the same topics. A third control group was exposed to content on the same themes, but in the form of short news excerpts and without social interaction. Participants were then required to play a trust game to measure their levels of trust.

The experiment found that levels of distrust were similarly low amongst those exposed to the uncivil content and the control group. Those who had been exposed to the polite content, on the other hand, displayed markedly higher levels of trust. The experimenters suggest (somewhat depressingly) that this means incivility and distrust are the norm when it comes to social media content, but (more encouragingly) that relatively little initial exposure to more civil content can have a significant impact on users’ subsequent behaviour and attitudes.

From their summary blog post:

"The striking result of our study is that even minimal exposure to the opposite trend, i.e. civil online interaction, has a significant effect on social trust. This suggests that what is at stake in moderating online discussion is not simply the prevention of negative phenomena (hate speech, cyberbullying, digital harassment, etc.), but also the achievement of significant social benefits, most notably a measurable increase in trust and social capital that can, in turn, positively affect economic development.
"The take-home message for policy makers is rather straightforward: instead of focusing exclusively on fighting against noxious online behaviour, we should also create the preconditions to promote civil discussion on online platforms. While the former goal needs to be pursued via strict regulations, the latter is best fostered by carefully designing (or tweaking) the platforms themselves.
"In doing so, freedom of expression needs to be preserved for all users, which is why we are sceptical that legal prohibitions alone can act as a panacea against online incivility. Instead, we should strive to effect a paradigm shift in what kind of interactions social media afford to their users: today uncivil and shallow confrontation is the norm, with civil debate relegated to being the exception; tomorrow it should be the other way around, thanks to social networking platforms designed to encourage reflective discourse, unbiased assessment of evidence, and open-minded belief change – while still leaving people free to verbally attack each other, should they feel so inclined."


“I did it for the Lulz”: How the dark personality predicts online disinhibition and aggressive online behavior in adolescence

Anna Kurek, Paul E. Jose, Jaimee Stuart

https://doi.org/10.1016/j.chb.2019.03.027

This study of adolescents in New Zealand investigates the relationship between pre-existing personality traits, online disinhibition, and what it terms “cyber agression”.

It finds that teenagers with “dark personality traits” (sadism, psychopathy, narcissism) are particularly susceptible to the effects of online disinhibition. Online disinhibition makes them more likely to manifest these negative personality traits.

"These results suggest, as Suler (2004) noted, that the underlying mechanisms of inhibited or disinhibited behaviour lie fundamentally within the processes of personality dynamics, and consistent with this view, the present findings provide empirical evidence that certain individuals may be at an increased risk of disinhibited behaviour online.


"Some youth, whose basic needs are grounded in dark motives, when exposed to a vastly uncontrolled and unmonitored space like the Internet, may gravitate towards the unhealthy development of disinhibited actions and attitudes
"Several significant results were found, namely that all three dark personality traits, as well as adolescent false self perceptions, were significantly and positively associated with increased online disinhibition. In addition, while only sadistic traits and online disinhibition were found to be significant direct predictors of cyber aggression, several indirect effects were also discovered, namely that all three dark traits became predictive of cyber aggression through the indirect role of increased disinhibition. Additionally, both narcissistic and psychopathic tendencies indirectly predicted cyber aggression through the mediation of both false self perceptions and online disinhibition."
