سؤال إنجليزي توجيهي في القراءة والاستيعاب

The sunk-cost fallacy is the idea that because you have already invested time or money in something, you should persist with it no matter what. One study asked people to imagine they were at a birthday celebration and that they were offered chocolate cake. The researchers told some people this was from a local supermarket, and others that it was an expensive handmade cake from a shop almost an hour away. Having been told the cake had required a significant investment of time and money seemed to make people much more likely to eat it all, even though they felt uncomfortably full.
