Honesty as a trait

The purpose of this paper is to review recent research about the possibility that some people are more honest than others and about the causes of them being so. We tackle four big questions about the consistency of honest behavior, the content and breadth of trait honesty, the mechanisms underlying trait honesty, and the measurement of trait honesty. Recent research reveals we are only at the beginning states of answering these questions about honesty. Invigorated research is needed to firmly resolve whether individuals differ in honesty and if so, integrate the determining mechanisms and develop strong measurements.
