The physiology of (dis)honesty: does it impact health?

Gender similarities and differences in dishonesty

We review the evidence linking gender to dishonesty and conclude that men are often more dishonest than women, especially in competitive settings where lies advance self-interest. However, gender differences in dishonesty are often small and mutable across situations. We propose that attending to self-regulatory constructs such as moral identity might help researchers move beyond the evolutionary-cultural debates over the origin of gender differences toward identifying factors that promote honesty from both genders.

When the truth helps and when it hurts: How honesty shapes well-being

Despite honesty being valued in many settings, there is some ambiguity regarding the conditions under which it is beneficial or harmful for individual and relational well-being. We review and evaluate current work linking honesty to well-being. Specifically, we highlight and distinguish associations between honesty and different types of well-being within people, between people, and among broader groups, organizations, and societies. Importantly, we provide additional context that explains why honesty is not universally associated with greater well-being-and how it may even incur costs for individuals. We provide suggestions for future directions for moving toward a more holistic understanding of honesty and the ways in which honesty can be used to understand individual and relational functioning.

Being good, doing good: The role of honesty and integrity for health

Psychological traits, such as character strengths, have been already established in experimental studies as factors playing a favorable role for well-being and potentially reducing the risk of depression. Positive associations have been also reported between character strengths and physical fitness, self-reported physical and mental health. Yet, evidence with large scale, epidemiological data on the role of character strength of honesty and integrity (CSHI) in shaping subsequent health outcomes and daily functioning remains unexplored. We examined whether the character strength of honesty and integrity was prospectively associated with six physical health outcomes, two depression outcomes, and two daily functioning outcomes. We used data from the Health and Retirement Study obtained from a sample of 9813 older adults. We found that after a 4-year follow-up period, compared with individuals who scored the lowest in CSHI, participants who scored in the third tertile had a 18% lower risk of lung disease (RR = 0.824; 95% CI = 0.732; 0.927), and a 11% lower risk of depression (RR = 0.891; 95% CI = 0.806; 0.986). They also reported lower limitations in mobility (β = -0.048; 95% CI (-0.089; -0.008)] and less difficulty in instrumental activities of daily living [β = -0.088; 95% CI (-0.128; -0.047)]. These associations were independent of demographics, prior socioeconomic status, psychological factors, health conditions, and health behaviors. Policy makers and practitioners may consider the character strength of honesty and integrity as a factor for promoting healthy longevity, limiting risks of becoming physically inactive and reducing risk of physical and mental disease.
