Interacting with other individuals, who are inevitably independent and not fully predictable, combined
with an inborn need to understand the actions of others, presents people with an overwhelming complexity. The impossibility of controlling the actions of others or even just fully understanding their motivation makes this complexity so staggering that it can actually inhibit intentions to perform many behaviors. Since people need, nonetheless, to interact on a continuous basis under such unpredictable circumstances,they apply a variety of methods for reducing this
crushing complexity. Without these complexity reduction methods people could not interact with others
on more than a onetime and uncommitted manner,and probably would not wish to, either. Trust is one
of the most effective of these complexity reduction methods (but not the only one), and is thus a focal
aspect in many interactions with other people [28].
This is especially the case in interactions that are not fully governed by rules and regulations [10], themselves
complexity reduction methods.
