Definitions of Trust: From Conceptual Components to the General Core - Trust Theory: A Socio-Cognitive and Computational Model - page 25

What we like here is the idea of a composite psychological state (although it is not fully
characterized), which does not only include 'positive expectations', but where these expec-
tations are the base for the intention to make oneself vulnerable. This crucial link is made
explicit in this definition, so it is less important that other beliefs are ignored (like the fact
that trust is also an appraisal), that the 'competence' and 'ability' of Y remain implicit, or that
there seems to be no trust before and without intention. Notice that - given this definition -
since trust necessarily includes the 'intention', the idea of trust might not be enough to entrust
Y , would be contradictory. One could never say: 'I trust Y but not enough', or 'I trust Y but I
do not intend to rely on him'.
This brief survey of various definitions of trust from different disciplines was just for
highlighting the main limits of the current (mis)understanding of this notion, but also a lot
of very important intuitions that - although partial and even contradictory - deserve to be
preserved, well defined, and coherently organized.
On the basis of these results, it is now time to start introducing in a more explicit and
systematic way our layered model of trust, which is what we shall do in the next chapter. 22
We will encounter and discuss other definitions and models throughout the topic.

and game-theoretic accounts of trust, considering both recent developments in this domain, and the old Deutsch's
definition of this notion.
