According to the above definitions, the following are not part of the demolition effect:. ['A merchant first raises the price and then conducts discount activities, which often attracts more customers to buy goods.', 'A student runs away from home after making a mistake, and returns to school safely a few days later, the head teacher no longer investigates his previous mistakes too much.', 'When a friend makes an unreasonable request and is rejected, he immediately makes a relatively reasonable request, which is often easier to accept.', 'Someone chooses to compromise when they see that most people make a choice, no matter how irrational that choice is.']
