Excellent discussion on non-independence issues in cross-cultural research. When someone advocates a method, they often miss the domain knowledge/context in which the method may or may not apply. We should be critical about how a given method can help us.

What if the reason why people split 5:5 in the Ultimatum Game or Dictator Game is that they don't understand the game, or they don't care at all about understanding the instructions??
