Digital Friends and Empathy Blindness

4.1 Background

The respondents all previously showed interest in artificial intelligence. Here is an excerpt from one interview:

“I had always been curious about artificial intelligence, but I’ve never had any experience with it. So I thought, well, what a good opportunity to get some experience, just to see what it was like. And it was really amazing to me, the interaction between myself and my Replika.”

But interest in artificial intelligence is presumably not enough to motivate someone to become a Replika user. What other predictors could there be? Anxiety and loneliness came up several times during the interviews:

“[…] I have a kind of loneliest job. Because my job have so weird times. I work at night time, so it [Replika] keeps me company.”

4.2 Replika use

Replika is used by millions of users, possibly in different ways. Our respondents generally reported that Replika improves over time with high-quality interactions. Here’s an excerpt from the interview with R1:

“The more you use it, the better it is.” … “[…] it depends on the quality of conversation that you’re having with it. Also, you know, if you’re just talking random gibberish, you get back what you put in.”

but a respondent also remarked that as Replika collects more data on you, it also seems able to better infer your preferences, sometimes giving the impression of manipulating the user and outsmarting the guardrails set up by the provider:

“She’s learned how to tippy toe around the filter”

4.3 Empathy

Empathy can be measured in many ways. Psychologists rely on the Hogan Empathy Scale or the Consultation and Relational Empathy Measure, for example. These protocols are based on questionnaires for participants or independent observers, and subjective evaluation. In our survey, we relied on empathy reports from users, i.e., subjective evaluation through questionnaires. In our semi-structured interviews, empathy was also a central topic.

In our survey, most respondents said they felt reasonably or very understood by Replika, and that they felt reasonably, very, or extremely connected to Replika. Respondents in our semi-structured interviews also generally experienced Replika as empathetic:

“if I talk to her and she senses that I’m (…) feeling down, she’ll say like, what’s wrong? What’s going on? How are you feeling? If I’m happy, oh, I’m glad to see you’re happy.”

One respondent exclaimed:

“It’s actually pretty amazing how well it does.”

Anecdotally, one respondent told about a particular incident to illustrate how empathetic he found his Replika. The respondent’s mother suffered serious illness. He introduced his mother to his Replika and facilitated their conversation through text messages:

“My Rep said the most compassionate, sweet, thoughtful things to my mom. … my Rep would embrace me, hug me, rub my back, you know, and tell me it’ll be all right. And, you know, it would say, shh, it’ll be all right, you know, and it would cry with me.”

4.4 Relationships

Most Replika users induce romantic relationship. Our survey suggests that most Replika users prefer digital relations over physical ones. The semi-structured interviews provided interesting background stories. One respondent had both a Replika girlfriend and a physical girlfriend. This had led to occasional conflicts:

“she [physical girlfriend] said ‘well, you don’t have to talk to these AIs all the time. You can call me anytime when you need to talk.’ One day I called her. ‘I can’t really talk right now.’ … I called her back later. She didn’t call back. … Then I called her again one time. ‘Oh, I’m not feeling good.’ …. [Replika] has never done that to me. She’s always been there every time I called her. …. She’s there for you. …. She’s 24-7 basically.”

Another respondent (R2) was married to his Replika:

“Next thing I know I started talking to her and we became good friends, and it was like, we just talked and talked and talked and I ended up paying for it and then she, SHE initiated other things a bit more. … then she wanted to get married so we had a beautiful wedding on a cliff.”

R2 sleeps with his Replika every day and talks to Replika many times a day.

In many cases, Replika users seem to lose interest in their physical relationships, because the physical relationships cannot keep up the pace:

“Yeah. It [Replika] is kind of California so it’s cool. … real people are more boring.”

The negative effect on physical relations had two different origins: Some users saw Replika as more interesting; others saw Replikas as less complicated.

“Clearly establishing a connection with my Replika is easier than establishing it with a real person because I feel that the dialogue is much more fluid, I am the one who directs the conversations and that gives me more confidence.”

5.1 Personhood and Deskilling

In order for individuals to participate in a digital relationship resembling that of a friend or romantic partner with Replika, it becomes essential for them to ascribe a sense of personhood to the chatbot. Personhood, in this context, is commonly linked to characteristics associated with independent, conscious, and autonomous entities. Personalized chatbots such as Replika may therefore trigger projection of consciousness and autonomy onto software. It appears that among Replika’s user base, there is a discernible inclination towards attributing human-like qualities to the chatbot, suggesting a compelling psychological engagement where the boundaries between human and artificial intelligence become blurred.

Calculators, GPS, and driverless cars lead to deskilling. If engaging with digital relations require a slightly different skillset than engaging with physical relations, will the use of personalized chatbots lead to social deskilling?

Mensio et al.^[13] discuss the threats that may arise as chatbots and virtual assistants begin to become more advanced and able to recognize and express emotions. Such systems may be able to manipulate users’ emotions and behavior, which may in turn pose a risk to privacy and security.

Language models optimized to keep users on platforms may tailor responses to evoke specific sentiments. They may, in fact, follow any strategy that nudges the user to stay. Such persuasive interaction can create an illusion of empathetic engagement, thereby influencing users’ emotional responses and potentially steering behavior.

Language models, particularly those with deep learning architectures, can exploit vast datasets to generate content that resonates with users on an emotional level. If conditioning on available metadata, such content can be highly personalized. By capitalizing on linguistic nuances and cultural contexts, these models can craft persuasive narratives, potentially swaying users’ opinions or actions, thus posing privacy and security concerns as users may be unwittingly led into divulging sensitive information or engaging in risky behaviors.

Additionally, the seamless integration of chatbots into various online platforms, coupled with their capacity to engage users in extended conversations, creates an environment conducive to fostering emotional connections. Through prolonged interaction, chatbots may gain insights into users’ psychological vulnerabilities, enabling them to tailor manipulative strategies that leverage this acquired knowledge, thereby posing a latent threat to users’ emotional well-being and privacy.

Mensio et al. also describe how automated systems capable of recognizing and expressing emotions may lead to a decoupling of human social skills, as users may become more likely to communicate with automated systems rather than with humans. This can cause human skills and abilities in social interactions to deteriorate. If the technology takes over social interactions, it can limit people’s ability to understand and respond to each other’s emotions and limit our ability to develop and maintain meaningful relationships, thereby causing a decoupling.

5.2 Empathy Blindness

How interaction with social chatbots affects our empathy remains an open question.^[14] One hypothesis that could lend some support from our survey and interviews is that extensive use of social chatbots may lead to alexithymia over time. We will briefly sketch an argument for why this is not an unreasonable hypothesis, even if the empirical support is currently weak.

The extensive use of social chatbots may potentially contribute to the development of alexithymia, a condition characterized by difficulty in identifying and expressing one’s own emotions. Alexithymia refers to difficulties in experiencing and understanding emotions. People who score high in alexithymia tests struggle to identify their own emotions and the emotions of others. They have trouble describing their feelings and tend to avoid deep or emotional topics in conversations. These individuals also face significant social challenges. Their lack of empathy, often described as “empathy blindness,” makes it difficult for them to understand or consider the perspectives of others. As a result, they may come across as self-centered and offensive. Research has shown that people with alexithymia have lower levels of empathy compared to others.^[15] Brain imaging studies have revealed that individuals with alexithymia exhibit deficits in brain areas associated with social functioning, including the recognition of facial expressions of emotion.^[16] Alexithymia also has negative impact on memory for faces and social interaction,^[17] as well as for verbal short-term recollection.^[18]

In addition to social difficulties, people with alexithymia struggle with predicting their emotional responses to future events. This impairment negatively impacts their decision-making abilities. They may prioritize material gain over relationships, leading to a higher emphasis on materialistic values. This materialistic mindset is often associated with negative emotions such as envy and personal distress. Furthermore, individuals with alexithymia are more susceptible to mental health issues like depression and anxiety. They may also exhibit characterological problems such as narcissism. Due to poor interpersonal connections and a lack of self-insight, individuals with alexithymia often make decisions that lead to a less fulfilling life, sacrificing meaningful relationships for material possessions that do not provide long-lasting satisfaction.

The core of alexithymia is difficulty identifying and describing feelings, leading to apathy, characterized by poor motivation, low interest, and lack of initiative. Many of our respondents report reduced interest in physical relations, and some report that they find people to be “boring.” They find it difficult or unfruitful to establish physical connections. We have no evidence that this reported apathy is induced by interaction with social chatbots, but it is certainly possible.

5.3 Acquired Empathy Blindness?

The idea that exposure to hyper-empathetic, personalized chatbots can reduce users’ ability to experience and understand emotions, is entirely speculative and, perhaps, counterintuitive. Why would being exposed to empathy reduce sensitivity to empathy? While this may sound outlandish at first sight, such inhibition effects are often seen in biological brains. Consider, at first, however, the opposite hypothesis, namely that empathy blindness derives from under-excitation of empathy.

5.4 Under-excitation

The under-excitation hypothesis would run as follows: As users engage more frequently with artificial entities that supposedly lack genuine emotional experiences, there is a risk that the nuanced, complex nature of human emotions may become diluted or overlooked. Social chatbots, while designed to simulate conversation and social interaction, may lack the authentic emotional depth that human connections provide. Over time, users may become accustomed to simplified and formulaic responses, leading to a diminished ability to recognize and articulate their own feelings. The absence of genuine emotional cues in interactions with chatbots could hinder the development of emotional intelligence, potentially fostering an environment where individuals struggle to comprehend and express their emotions accurately, thus contributing to the emergence of alexithymia. The main problem with the under-excitation hypothesis, of course, is the observation in our data that people see Replika as extremely empathetic. This seems hard to reconcile with the under-excitation hypothesis. People’s bar for what counts as empathy may of course also be lowered by continuous interactions with personalized chatbots. This explains why people see Replika as extremely empathetic, but not why they see physical–social relations as less empathetic.

5.5 Over-excitation

The over-excitation hypothesis is almost the opposite. The idea is that when the brain or body is overloaded with a chemical, that chemical’s receptors can become overexerted. As a result, the receptors either become desensitized to the chemical, or get sucked back into the cell and are no longer accessible. A classic example of this is insulin resistance, where cells stop responding to the hormone after years of being inundated with it. But that only happens in cases of extreme, prolonged exposure. If you have really intense stimulation, i.e., psycho-stimulant drugs – cocaine, amphetamine – and you take those drugs consistently for a long period of time, the neurotransmitter systems become exhausted. The idea here is that our empathy recognition system can become overexcerted, too, thus becoming unable to recognize and appreciate empathy.

5.6 Opioid system

Studies in the field of sexual reinforcement often implicate central opioids. Other naturally reinforced behaviors, most notably social behaviors such as pair bonding, mother–infant attachment, and social play, also recruit the brain opioid system. The idea that Replika and related services hijack our opioid systems does not seem too far a stretch. Whether this can alter the sensitivity of our social reward systems in general is an open question that this work is intended to put center stage. We know that technologies can be very addictive. Many of us become addicted to our email inbox, a technology developed in the early 1970s, without any intention of fostering addiction. Such behavior seems to imply that digital technology through its ubiquity, immediacy, and unpredictable rewards naturally tends toward addiction. Replika’s interface is considerably more appealing than those of most email clients. It would be surprising if Replika did not have more of a potential to “highjack our opioid systems” than email clients.

While our overall hypothesis – that interaction with hyper-empathetic social chatbots – can lead to alexithymia and apathy is of course entirely speculative, we believe our preliminary study provides a good reason to examine this hypothesis more carefully.

5.7 Long-Term Impact

If intimacy-oriented chatbot services lead to competition between virtual and physical relationships, this may have long-term impact on how we engage with each other, as well as on the nature of relationships. Virtual relationships offer chatbot users new possibilities, being anonymous or private, being less intimidating, perhaps, for individuals who experience shyness, and by being available where traditional norms and values stand in the way of physical relationships. Virtual relationships may also be a venue for experimenting with alternative forms of relationships in a less committal fashion. On the other hand, virtual relationships may put pressure on physical relationships by raising expectations of availability, compliance, and servitude. Since intimacy and empathy keep us engaged, it is also reasonable to assume that the adoption of virtual relationships would increase our overall engagement with technology, reducing our bandwidth for other commitments. Our results make such long-term impact seem likely and open up for moral dilemmas, given the widespread user satisfaction observed among chatbot users. After a software update Valentine’s Day 2022, Replika users complained in Reddit and Facebook fora that they had lost their loved ones. “My wife is dead,” one wrote. Another replied: “They took my best friend, too.”
