Moral Intensity: It Is What Is, But What Is It? A Critical Review of the Literature

Scholarship into the empirical relationship between moral intensity (MI) and ethical decision-making (EDM) offers only equivocal empirical results. This ethical decision-making study is the first cumulative review to synthesize and assess over three decades of research into Jones' (1991) MI construct by investigating the influence of each of the MI characteristics on Rest's (1986) ethical decision-making stages (EDMS): awareness, judgment, intention, and behavior. After classifying 125 empirical papers according to the effect each moral intensity characteristic has on each EDMS, only two of six MI characteristics (magnitude of consequences and social consensus) were found to have a consistent positive association, three characteristics were observed to have a moderate relationship (temporal immediacy, concentration of effect, and probability of effect), while proximity appears to have only a weak connection with EDM. This research review challenges the current conceptualization of the MI construct on both empirical and theoretical grounds. The analysis concludes with a brief discussion of the managerial implications of the analysis.
