I’ve said before that relationships suffer from the bias that "We tend to remember slights and frustrations more than favors and kindnesses." More now from Marginal Revolution:
Immediately after one person performs a favor for another, the recipient of the favor places more value on the favor than does the favor-doer. However, as time passes, the value of the favor decreases in the recipient’s eyes, whereas for the favor-doer, it actually increases.
Remember that when you accuse someone of looking at their partner(s) with excessively rose-colored glasses.
This is one thing where Ripple can help with - if you get into the habbit of keeping track of favours and allocating trust for unconditional favours, the gratitude is there to push future trades that might otherwise be impossible, reducing autarky.
Perhaps there is a bit of sense to that, Hanson. Would you hang out with a person who frustrates only very slightly less than he makes you happy?
