Do East Asians Really Self-Enhance Less Than North Americans? Research

Do East Asians really self-enhance less than North Americans? Research has examined a number of alternative explanations.These include all of the following EXCEPT

A) East Asians self-enhance just as much as North Americans but Western biases in our research methods prevent us from seeing these motivations.
B) East Asians self-enhance just as much as North Americans but only when researchers measure traits that are important to East Asians.
C) East Asians self-enhance just as much as North Americans and studies that say otherwise are flawed because they aren't measuring people's true feelings and are instead inadvertently measuring cultural norms for describing oneself.
D) East Asians self-enhance just as much as North Americans if researchers go beyond measuring adult college students and also study children and groups with less traditional educational experiences.
E) All of these alternative explanations were discussed in the textbook.
