TLDR
Feeling lonely can change how people notice and interpret social situations. They may spot possible rejection, assume bad intentions, and doubt their ability to connect, which can make loneliness harder to escape.

1 Study Aim
The authors reviewed whether loneliness is linked to information-processing biases, meaning systematic tendencies in how people notice, interpret, remember, and use information. They examined whether lonely individuals focus more on social threats, interpret others negatively, evaluate themselves poorly, and feel less capable in social situations. The review also considered whether these patterns could help maintain loneliness. Loneliness may shape how people understand social experiences, making connection feel more difficult.
2 Study Design
The paper presents a review of research examining loneliness and several stages of social information processing (SIP), meaning how people handle information about other people. The authors brought together findings on attention, interpretations of others’ intentions, expectations of rejection, evaluations of self and others, goals, memory, and perceived social ability. The source material does not report one combined participant sample or a single experiment. Instead, it compares results across existing studies and notes that some findings are inconsistent. The researchers combined evidence from many separate studies rather than testing participants in one new experiment.
3 Findings
The review reports that lonely individuals often show greater attention to socially threatening stimuli, such as possible rejection. They are also more likely to make negative or hostile intent attributions, meaning they assume others may mean harm. The authors describe negative evaluations of themselves and others, stronger rejection expectations, prevention-focused goals, and lower self-efficacy, or confidence in handling social situations. However, the review notes inconsistent findings across some areas. It suggests that these patterns may encourage withdrawal and help maintain loneliness. The authors highlight the need for research and interventions that directly target biased social information processing. Lonely people may notice danger and rejection more readily, which can make positive relationships harder to build.
