The global tipping divide
Professor Michael Lynn at Cornell University has spent decades studying tipping behavior across cultures. His landmark 1993 study with Zinkhan and Harris examined tipping customs in 30 countries and found something surprising: the practice varies so dramatically that there’s no universal “right” approach.
The American model is the exception, not the rule.
Lynn’s research identified a clear pattern: countries with higher individualism scores (like the US and Canada) have stronger tipping norms. Collectivist cultures (like Japan and China) view tipping as unnecessary or even insulting - good service is a professional duty, not something requiring additional payment.
