Question

Quizplus · Accepted Answer

Both experiments showed that people's beliefs and expectations can have a significant impact on behavior and well-being. The ginkgo biloba experiment demonstrated that participants who believed they were taking the supplement reported better memory and cognitive function, even if they were actually taking a placebo. The hotel experiment showed that participants who believed they were working in a high-status job (even if it was just temporary) reported feeling better physically and mentally. These findings suggest that our beliefs and expectations can play a powerful role in shaping our experiences and outcomes.
