Now I understand why globalisation is dangerous; if people start to favor short term relationships (both personal and business) with many different partners (smaller number of rounds <interactions> per match <lifetime>), then society will evolve to become full of cheaters.
And for physical businesses, we have things like Yelp. We are effectively trying to anticipate our opponents behavior through a trusted intermediary.
There was a Black Mirror episode on giving every person on the globe their own rating. It seems that may be the actual destination that we're headed for.
"Nosedive".
One of the scariest things I've ever seen on screen. I joke about how realistic black mirror is but that episode was too much. Beyond uncanny. It was incredibly hard to watch and I hated every second of it. Awful. Cannot recommend it enough.
For one thing, people can build trust with the intend to abuse it after a longer period of time. An abuser, for example, could plan to offer 20 "good rides" on Uber until s/he strikes. For another thing, many people have learnt to skillfully simulate trust which may pose a problem for you. For instance, you may believe to be in a loving relationship but all of a sudden you find out that the other person isn't interested in you at all and just didn't want to be alone etc.

The economic incentive to encourage cheaters is the reason why the "trusted intermediary" should always be verified.
EDIT: Which is to say, a global community of 7 billion is absurd but not all that much more absurd than a city-state of 50 thousand.
Perhaps we'll soon see a new religion?
Countries where personal relations are important for business suffer from smaller number of opportunities because forming personal trust takes time.
Basically with globalization, social media etc... The number of relationships have gone up but the quality and depth of each relationship has gone down. This makes it harder for the rational copycat personality type who relies on empirical evidence to build trust.
Another study, [http://journals.plos.org/plosone/article?id=10.1371/journal....], contains a short literature review of "the effect of formal institutions–including markets–on trust" and concludes that existing evidence is inconclusive.
(these studies are about market institutions, not explicitly globalization, but one could imagine that globalization could involve more market institutions; my point is just that globalization involves all sorts of factors, some of which are probably pro-cooperation and some of which are probably anti-cooperation, and it's not immediately clear whether the final outcome will be more cooperation or less)
