Susan Sprecher and Susan Hendrick (2004) studied heterosexual dating couples and found strong correlations between several measures of satisfaction and self-disclosure for both partners
Men and women who used self-disclosure (and believed their partners did likewise) were more satisfied with and committed to their romantic relationship
Sprecher et al. (2013) showed that relationships are closer and more satisfying when partners take turns to self-disclose (i.e., disclosure is reciprocated)
If less-skilled partners (e.g., those who limit communication to small talk) learn to use self-disclosure, this could bring several benefits to their relationships in terms of deepening satisfaction and commitment
They concluded that men and women in the US (generally an individualist culture) self-disclose significantly more sexual thoughts and feelings than men and women in China (generally a collectivist culture)
Strength of evidence that physical attractiveness is associated with a halo effect
Carl Palmer and Rolfe Peterson (2012) found that physically attractive people were rated as more politically knowledgeable and competent than unattractive people
Strength of the role of physical attractiveness as research support for evolutionary processes
Michael Cunningham et al. (1995) found that women with features such as large eyes, prominent cheekbones, small nose, and high eyebrows were rated as highly attractive by white, Hispanic, and Asian men
This consistency across different societies suggests that attractive features are a sign of genetic fitness and are perpetuated similarly in all cultures, supporting sexual selection
Lindsay Taylor et al. (2011) studied the activity logs of a popular online dating site, providing a real-world test of the matching hypothesis by measuring actual date choices rather than preferences
They found that similarity of values was associated with closeness for couples together less than 18 months, while complementarity of needs predicted closeness in longer relationships
Patrick Markey and Charlotte Markey (2013) found that lesbian couples of equal dominance were most satisfied, with relationships averaging over 4½ years
Strength of evidence from real-world relationships supporting equity theory as a more valid explanation than Social Exchange Theory (SET)
Mary Utne et al. (1984) surveyed 118 recently-married couples, finding that those who perceived their relationship as equitable were more satisfied than those who felt overbenefitted or underbenefitted
Katherine Aumer-Ryan et al. (2007) found that in individualist cultures like the US, couples were most satisfied when their relationships were equitable
Richard Huseman et al. (1987) identified "benevolents," who are willing to contribute more than they receive, and "entitleds," who feel they deserve to overbenefit without distress
Cues like message style and timing play significant roles in online interactions, challenging the theory's assumption of reduced personalization online
The use of acronyms, emoticons, and emojis serves as effective substitutes for facial expressions and tone of voice, suggesting that virtual relationships can be as personal as face-to-face (FtF) ones
Evidence suggests that online self-presentation differs from FtF interactions, with virtual interactions often featuring unique conversational patterns and hyperdishonest self-disclosures, such as embellishing online dating profiles
Strength of support for the absence of gating in virtual relationships
Shy, lonely, and socially anxious individuals benefit from virtual relationships, indicating the absence of gating barriers present in FtF interactions
Research by McKenna and Bargh (2000) demonstrates that such individuals can express their true selves more freely online, leading to successful long-term relationships
They found that individuals classified as borderline-pathological or intense-personal tended to experience high levels of anxiety in their intimate relationships
