Do people benefit when they think their partner has made a sacrifice for the relationship? In a multimethod study of 80 couples, we examined whether people can detect when their partner suppresses their emotions and if perceived partner suppression is costly for the recipient of sacrifice. When people listened to their partner recall an important sacrifice in the lab and when people thought the...

What happens when people suppress their emotions when they sacrifice for a romantic partner? This multimethod study investigates how suppressing emotions during sacrifice shapes affective and relationship outcomes.

Centuries' worth of cultural stories suggest that self-sacrifice may be a cornerstone of our moral concepts, yet this notion is largely absent from recent theories in moral psychology. For instance, in the footbridge version of the well-known trolley car problem the only way to save five people from a runaway trolley is to push a single man on the tracks. It is explicitly specified that the bys...

When a quantum cryptographic system operates in the presence of background noise, security of the key can be recovered by a procedure called key distillation. A key-distillation scheme effective against so-called individual (bitwise-independent) eavesdropping attacks involves sacrifice of some of the data through privacy amplification. We derive the amount of data sacrifice sufficient to defend...

This paper distinguishes between self-sacrifice and altruism, and reports a cross-sectional survey of working managers (n = 127). The study tested how the two variables differentially affect transformational leadership. Results yielded evidence that altruism is a better predictor of transformational leadership than self-sacrifice is. The hypothesis that self-sacrifice would enhance the effect o...
