I came across this example in Nudges and Cultural Variance: a Note on Selinger and Whyte.
"Suppose that an Englishman and an Irishman go to the races and win 1K in their respective currencies. Subsequently, they invest their gains into a new bet and they lose. Then the Englishman is depressed because he lost 1K where the Irishman is indifferent because he neither gained nor lost anything. The suggestion is that the Irish are less subject to the endowment effect than the English"
So, the effect of nudges may vary according to cultures. They might work or not
