Better less, but better – something like this can be paraphrased by the recommendations of psychologists from the University of Virginia to those who want to pick up a good gift for someone close.
You should not “increase the volume” of an expensive gift at the expense of other, cheaper ones – this is the competent advice of psychologist Kimberlee Weaver from the University of Virginia (USA). It may seem to the giver that in this way he increases the overall value due to an additional pleasant surprise, but from the point of view of the recipient, the significance of the gift is “blurred” (the arithmetic mean principle works). However, this argument should not stop us if we have something to give to a person who is pleasant to us.
