EN: A. Terracciano et al. published today in Science the article "National Character Does Not Reflect Mean Personality Trait Levels in 49 Cultures" (Science, Vol 310, Issue 5745, 96-100 , 7 October 2005). It is also a good example for selective perception.
Here's the abstract:
Most people hold beliefs about personality characteristics typical of members of their own and others' cultures. These perceptions of national character may be generalizations from personal experience, stereotypes with a "kernel of truth," or inaccurate stereotypes. We obtained national character ratings of 3989 people from 49 cultures and compared them with the average personality scores of culture members assessed by observer ratings and self-reports. National character ratings were reliable but did not converge with assessed traits. Perceptions of national character thus appear to be unfounded stereotypes that may serve the function of maintaining a national identity.
