Smaller (less dominant) football players displayed more smiling than larger (more dominant) football players (F(1.41, 38.10) = 111.80, partial η² = .81).<ref>http://doi.org/10.1177/147470491201000301</ref>
 
Smiling signals positive emotion, benevolence, submission, compliance/appeasement and absence of threat.
For example, people often smile in cases of excuses and embarrassment.<ref>Ekman, P.& Keltner, D (1997). The social function of "smile" and "laughter": Variations across primatespecies and societies. In U. C. Segerstraleand P. Molnar (Eds),Nonverbal communication: Where naturemeets culture, (pp. 27-46). Hillsdale, New Jersey:Lawrence Erlbaum.</ref>
Dominant individuals smile less, perhaps to maintain the threat of their dominance and acts as a costly signal of their status in that they do not need to fear being judged not needing to signal compliance.
 
Higher levels of testosterone are associated with dominant behavior and less smiling.<ref>Dabbs, J. M. (1997). Testosterone, smiling, and facial appearance.Journal of NonverbalBehavior,Vol.21,pp.45-55</ref> Smaller (less dominant) football players displayed more smiling than larger (more dominant) football players (F(1.41, 38.10) = 111.80, partial η² = .81).<ref>http://doi.org/10.1177/147470491201000301</ref>
 
Men smile less than women because they have higher status and women are more agreeable/compliant, presumably related to their more child-like, shorter and weaker statue.<ref>LaFrance, M., Hecht, M. A.,andLevy Paluck, E. (2003). The contingentsmile: A meta-analysis of sexdifferences in smiling.PsychologicalBulletin,Vol.129,pp.305–334</ref> In social encounters women smile 87%, but men only in 67% of the time.
In portrait photographs from high school and university yearbooks, women do not smile 8% of the time, but men do not smile 41% of the time.<ref>https://link.springer.com/article/10.1007/BF00287672</ref>
