Why is it allowed for them but not for us? Where do social norms come from

In some countries, cities, companies, and families, people are relaxed about 15-minute delays, litter on the ground, wrinkled clothes, animated gesturing, interruptions from children to adults, and subordinates to management. In others, you will be harshly punished for the slightest lack of punctuality, chewing gum that misses the trash can, an extra comma in a document, or disrespectful eye contact. Why are established norms strictly followed in some cultures, while independence and initiative are actively encouraged in others? Why do people adhere to established norms, sometimes against common sense? Where do norms even come from? These questions concern many people living in an era of change, including modern Russians. The author of the book, psychologist Michele Gelfand, explores the historical, social, and economic reasons for the most common freedoms and restrictions, as well as analyzing the advantages and disadvantages of both systems — strict and free.
