Answer:
The correct answer is: Overattribution.
Step-by-step explanation:
Over-attribution is a cognitive bias. Over-attribution is the tendency that people have to attribute the behavior of other people to whatever information or whatever factor is most present to the person making the attribution.
For instance in this particular case, One is assuming Ling is highly conscientious not because she is a conscientious person, but because one has the information that Asian people tend to be highly organized and responsible.
Right there one is committing the over-attribution error.
