>Americans, on the other hand, tend to pounce on admissions of failure or ignorance, and engage in shaming and humiliation of the person that admits an issue.

Shoutout to all the foreigners working in the US that don't say that know everything, are quiet in meetings when everyone is yelling out stupid ideas, regularly give up their design when a competing one gets promoted loudly, then never get promoted. Eventually you'll learn never to admit failure or ignorance and eventually start demanding who made the error.
