The Immigrant Next Door
研究长期接触某一外来族裔如何改变本地人对该群体的态度和行为，发现长期接触阿拉伯穆斯林会减少偏见、增加捐赠和接触。
We study how decades-long exposure to individuals of a given foreign descent shapes natives’ attitudes and behavior toward that group. Using individualized donations data, we show that long-term exposure to a given foreign ancestry leads to more generous behavior specifically toward that group’s ancestral country. Focusing on exposure to Arab Muslims to examine mechanisms, we show that long-term exposure (i) decreases explicit and implicit prejudice against Arab Muslims, (ii) reduces support for policies and political candidates hostile toward Arab Muslims, (iii) increases charitable donations to Arab countries, (iv) leads to more personal contact with Arab Muslims, and (v) increases knowledge of Arab Muslims and Islam.
