=== Accuracy === Many researchers compare individuals’ cognitive social structures to the actual social structure in order to measure consistent errors, or biases, involved with cognitive social structures. While some research shows that individuals’ representations correlate with the aggregate group's representation, there are systematic errors that occur as a result of network position and individual differences. Many researchers have studied the effects of and the perceptions of centrality, or how well connected one is within the network. Broadly, individuals tend to believe they have higher centrality (i.e. better connected within the network) and higher degree (e.g. more friends) than others believe. Furthermore, members who have low centrality, such as those who are on the periphery of the network or at the bottom of the hierarchy (unpopular, low status), tend to have more accurate representations than those who are more central (popular, high status). Several studies suggest that social network representations track overall patterns of behavior, rather than specific events. Furthermore, there appears to be a trade-off between overall accuracy and specific event accuracy: those who remember details of a specific interaction tend to have less accurate representations of overall behavior patterns, while those with more accurate pattern representations have more trouble recalling event details. This can cause issues when studying cognitive social structures because, often, the only way to determine the true social network is by observing behavior. If, however, the researchers do not sufficiently observe the network, then the observed behavior may not be representative of the overall patterns of behavior. Some research suggests that people extract these patterns of behavior by tracking the frequency of interactions, assuming that the more frequently two people interact, the more likely they are connected. This leads to the belief that people are more connected than they actually are. In accordance with balance theory, people tend to believe that the missing relation in unbalanced groups (e.g. groups of three in which two members are connected to the third but are not connected themselves) actually exists, thereby believing the triad is balanced. This is especially true when considering triads that are very close to the individual and very distant, but not for members who are intermediately far away. Beyond accuracy, research also highlights the importance of alignment in perception among partners. Thatchenkery and Piezunka (2025) highlight that is crucial whether collaborating firms are aligned in whether they perceive each other as competitor.
=== Neural Findings === Research indicates that the interpersonal relationships among people shaped the evolution of human brains. Neuroimaging work has identified specific regions in the brain that aid in network representation, many of which are included in the default mode network, and track network position properties, such as eigenvector centrality, brokerage, and popularity. That is, when participants see a network member's face, they automatically retrieve information about that person's network position, suggesting that this information is important in understanding that person. Much of the research relating social networks to neural measures focuses on physical size and density of brain regions. Research shows that social network size correlates with brain volume in specific regions, including the amygdala and regions associated with the default mode network, which is thought to process information about others' thoughts and feelings.
=== Individual Differences === Studies on individual differences in cognitive social structures examine how individuals' traits affect their perceptions of social networks. Following are specific aspects of individuals that researchers have found influence cognitive social structures. Need for closure, which refers to one's tendency to avoid ambiguity, has been shown to correlate with the number of ties that are perceived as transitive. That is, the higher one's need for closure, the more likely they are to perceive unbalanced groups as balanced. Additionally, people with high need for closure tend to cluster people by racial similarity in their representation of social networks. Status, Power, Popularity: in real-world social networks, low-power members tend to have more accurate perceptions of social networks than high-power individuals, particularly regarding people who are distant to the perceiver. One study found that these low-power individuals with accurate network perceptions received more payoffs compared to other low-power members with less accurate perceptions. However, the benefits to low-status individuals with accurate network knowledge only held if other low-status people had worse knowledge. Similarly, in a controlled setting, participants primed with low-status then had more accurate representations of a social network, but not of a non-social network. This research suggests that one's own status is an important factor in their representation of their social networks, because high power prompts people to use heuristics, while low-power people use more systematic methods to understand the network. There has been much research on how people perceive their social network and the differences between these perceptions. Other individual differences measures have been suggested to influence cognitive social structures, including need for achievement, need for affiliation, and self-monitoring. However, since studies often use different types of networks (e.g. real-world organizations, friend groups, communication networks), there is not yet consensus on the effect of these differences.
