What concept best describes an unwillingness to acknowledge cultural differences?

Cultural bias best describes an unwillingness to acknowledge cultural differences because it refers to the inclination to interpret and judge other cultures primarily through the lens of one's own cultural norms and values. This bias can manifest in various ways, such as dismissing or devaluing the beliefs, customs, and practices of other cultures. It leads to a lack of understanding and appreciation for the diversity that exists in human experiences, as individuals fail to recognize or respect differing perspectives and traditions. In contrast, the other concepts listed do not specifically relate to cultural differences. Item bias refers to issues in assessment items that may disadvantage certain groups, dramatic irony involves a situation where the audience knows more than the characters, and verbal irony is when someone says one thing but means another. Therefore, only cultural bias directly addresses the reluctance to recognize and embrace cultural diversity.
