Why are there (almost) no left-handers in China?

Area of Science:

• Human laterality
• Cultural anthropology
• Sociology

Background:

• Global prevalence of left-handedness is estimated between 10-12%.
• Surveys in China since the 1980s report less than 1% left-handedness among students.
• This discrepancy prompts an investigation into the reasons behind low left-handedness rates in China.

Purpose of the Study:

• To explore the reasons for the low reported prevalence of left-handedness in China.
• To examine the interplay of cultural, historical, and biological factors influencing attitudes toward left-handedness.
• To understand the societal pressures and discrimination faced by left-handed individuals globally.

Main Methods:

• Review of historical and cultural factors influencing attitudes toward left-handedness in China.
• Comparative analysis of practices in other societies, including North and East Africa.
• Synthesis of traditional values and practical considerations shaping left-handedness prevalence.

Main Results:

• Chinese attitudes and practices toward left-handedness are shaped by a combination of factors.
• Historical and cultural experiences, including traditional values and practical considerations, have merged to reduce left-handedness.
• Similar practices of attempting to 'cure' left-handedness exist in other cultures, often reinforced by religion.

Conclusions:

• The low prevalence of left-handedness in China is likely due to a convergence of cultural and historical forces.
• Attitudes and practices toward left-handedness are over-determined, transcending specific cultures while responding to unique pressures.
• Left-handedness is associated with discrimination and stigma for a significant portion of the global population, including China, India, and the Islamic world.
