American researchers studying the effects of physical attractiveness on compliance wish to expand the cross-cultural generalizability of their findings to a Lebanese population. They travel to Lebanon and recruit local residents, whom the American researchers rate as attractive or unattractive, to act as experimental confederates. However, they are unable to replicate their research findings. What is a potential problem with this research?
A. Inter-rater reliability has not been assessed.
B. Language barriers will prevent successful research from occurring.
C. The study may not be reliable due to differences in expectations for compliance between cultures.
D. The study may not be valid due to differences in standards of attractiveness between cultures.

Explanation: Culture is the way of life of a given set of persons. Cultures contain unique attributes specific for its own culture,what is seen as a not a proper way of life may be considered in another culture as a normal way of life. The standard or what is seen to be attractive in one culture may not be attractive in another culture.

All experiments must have the potential of it been replicated for it to be seen as valid and true, when conducting experiments one have to take related samples to what you want.

Lebanese Culture and the western culture are quite different.
