Age-based discrimination is considered undesirable, yet we know little about age stereotypes and their effects on honesty and trust. To investigate this aspect of ageism, we presented older adults (over age 50) and younger adults (under age 25) with incentivized belief elicitation tasks about...

Consistent with a modular view of the mind, both short-sighted and long-sighted programs may be simultaneously active in the mind and in conflict with one another when individuals face choice dilemmas in trust-based economic interactions. Recalibrational theory helps us identify the adaptive...

In the absence of enforceable contracts, many economic and personal interactions rely on trust and reciprocity. Research shows that although this reliance often works well, sometimes it breaks down. Simple rules mandating minimum standards on reciprocation prevent the most egregious trust...

Though individuals differ in the degree to which they are predisposed to trust or act trustworthy, we theorize that trust-based behaviors are universally determined by the calibration of conflicting short- and long-sighted behavior regulation programs, and that these programs are calibrated by...

Many economic interactions are characterized by “all or nothing” action spaces that may limit a demonstrable index of trust and, therefore, the propensity to reciprocate. In two experimental trust games, the action space governing investments was manipulated to examine the effects on...

Despite normative predictions from economics and biology, unrelated strangers can often develop the trust necessary to reap gains from one-shot economic exchange opportunities. This appears to be especially true when declared intentions and emotions can be cheaply communicated. Perhaps even more...

Discrimination based on age can affect same-aged and intergenerational interactions, presenting socially and economically undesirable phenomena. To investigate the effects of age stereotypes on cooperation, we presented older adults (over age 50) and younger adults (under age 25) with belief...

We investigated whether 20 emotional states, reported by 170 participants after participating in a Trust game, were experienced in a patterned way predicted by the “Recalibrational Model” or Valence Models. According to the Recalibrational Model, new information about trust-based interaction...

Using trust games, we study how promises and messages are used to build new trust where it did not previously exist and to rebuild damaged trust. In these games, trustees made non-binding promises of investment-contingent returns, then investors decided whether to invest, and finally trustees...

On-the-job leisure is a pervasive feature of the modern workplace. We studied its impact on work performance in a laboratory experiment by either allowing or restricting Internet access. We used a 2×2 experimental design in which subjects completing real-effort work tasks could earn cash...
