One interesting thing about this is that the effect of printing money (how it influences inflation) highly depends on perception. Radio Lab talked about this in a recent episode[0]. This has been a measured effect too and so it is interesting that fearing inflation can be a self fulfilling prophesy.
The best example of how perception matters was how the careful introduction of the Brazilian real ended hyperinflation merely by creating a perception that it wouldn't inflate. (It was pegged to the old currency at a rate that inflated at the same rate that the old currency did. All stores had to post prices in both old and real. After people were used to seeing real standing still, Brazil started printing them and continued indexing them at inflating rates to the old. And the price stayed constant as the old currency was replaced by the new.
