Final answer:
John's refusal to buy Japanese products because he sees it as a way of selling out to a nation known for its aggressive behavior is an example of the self-reference criterion.
Step-by-step explanation:
John's refusal to buy Japanese products because he sees it as a way of selling out to a nation known for its aggressive behavior is an example of self-reference criterion.
The self-reference criterion refers to the unconscious biases and assumptions that individuals have about their own culture, which they use to evaluate and make decisions in relation to other cultures.
In this case, John is using his own cultural beliefs and perceptions about Japan's aggressive behavior to judge the quality and worthiness of Japanese products. By doing so, he is letting his self-reference criterion influence his decision-making process.
