But ... This feels like the behavioural economist trick - getting people to behave morally or not in dividing up a pot of money. It turns out that people have comfort zones, areas of expertise where they are good at applying their skills and moral compasses. So in the economists trick, taking people out of the lab and making moral decisions at work they become more comfortable and less liable to change their minds
I suspect that if you asked a Palestinian aid worker just back from gaza their views and then bait and switched them, you might find they spot the move ! I also suspect the same person could be tricked over the morality of sugar tarrif duty in the US and Iowas farmers.
