Citing a study by Shawn Powers at USC and Mohammed el-Nawawy at Queens University titled,”Al-Jazeera English and global news networks: clash of civilizations or cross-cultural dialogue?” Elisabeth Best at Miller-McCune writes:
But researchers found that the longer participants had been watching AJE, the less dogmatic they were in their thinking, as measured by a survey evaluating dependence on particular networks and support for U.S. policies. This is not to say that AJE viewers were not affected by the opinions promoted by the network: The more frequently participants tuned into AJE, the less supportive they were of the U.S. policy toward the Palestinian-Israeli conflict and the more critical they became of U.S. policy in Iraq.
The reduced dogmatism applies only to the cognitive levels of thinking, or the way in which people process new information. People who are less dogmatic in their thought are more open to information that contradicts their worldviews, whereas people who think very dogmatically are more likely to ignore or minimize information that does not support their own beliefs. These levels of dogmatism are strongly related to political and cultural tolerance, and how people behave in confrontational situations.
