According to medical information website MedicalXpress, experts from Stevens Institute of Technology in the United States pointed out that the aroma of coffee can improve people's performance in performing analytical tasks, such as improving candidates' GMAT (graduate management entrance examination for foreign business schools). Experts believe this is due to the placebo effect.

About 100 students took part in the experiment to solve 10 GMAT algebra problems. They were divided into two groups, one group solved the problem under the aroma of coffee, and their grades were better than those of the control group.

In addition, scientists conducted a poll of 200 people to see how different tastes affect people's activities. Respondents believe that the aroma of coffee can increase vigilance and vitality, improve production efficiency, and improve people's performance of various tasks. Considering that the aroma of coffee in the experiment does not come from caffeine, experts believe that the results can be explained by self-suggestion.

The researchers believe that in this case, the placebo effect can be applied to all areas of life, including business. For example, the faint aroma of coffee can be used to improve the productivity of students and employees.
