It's 2022, and there are still people who believe that "the average length of white black Tintin is longer than that of East Asians"? It must be pointed out that no country in the world has done a Tintin length survey of men around the world, because the number of samples is less than objective and rigorous, and the number of samples is too large, and it will cost a huge amount of manpower and money to investigate, for example, there are 66 cities in the United Kingdom, if in order to study accurately, according to the proportion of cities, at least 66 ×4 = 264 samples (not necessarily every city to investigate, can be concentrated in a few larger urban agglomeration areas), and typical white countries, southern Europe two, Three in Eastern Europe, four in Western Europe, one in Northern Europe, and one in North America, a total of eleven white countries had a sample size of 264 ×11=2904, while the total number of East Asians and blacks was 8712.
This is equivalent to dozens of countries across five continents to do research, taking Chinese to Southeast Asian countries as an example, the ticket alone costs hundreds of dollars, counting accommodation, food costs of no less than thousands of yuan, and to do such a large range of research and research, the money spent is absolutely huge.
That's why no country has done a survey of the average length of tintin in men around the world. So where did the data on average lengths by country come from? Mainly data from the physical examination of the urology department of the hospital.
To date, the largest number of surveys have been done by King London College in the United Kingdom, but their survey is also a collection of urology and related papers from various countries combined to study, their research sample size totals more than 15,000 men (the vast majority of participants in the survey are white, black, Asian rarely participated), published in the International Journal of Urology in 2015, the average length of men is 13.12 cm, the researchers also said that the average length of male tintin and height, weight, BMI, Foot size, ethnicity, or race all have nothing to do with each other.
The third image shows an Italian survey of 3300 young men with a tintin length, which yielded an average length of 12.5 cm.
