(HealthDayNews) -- You learned it in Economics 101 -- people make purchase decisions based on price. Adam Smith wrote it in The Wealth of Nations back in 1776, and it has recently been confirmed in the journal Appetite.
Researchers from the Department of Physiology at Laval University in Quebec invited a test group for a free lunch. The subjects were asked to rate 10 types of sandwiches on the basis of taste. As long as the meal was free, the good-tasting sandwiches went first.
When the same people were invited back, this time there were price tags on the sandwiches, with the best-tasting ones selling at the highest prices.
This time, the people chose food they didn't like in order to save money, the study found.
