The transformation of a bundle of more or less deep insights on a few voting procedures, as we saw in a preceding entry, into something like a general logico-mathematical theory about the aggregation of individual preferences into a collective choice was the work of a single man, Kenneth Arrow, in his 1951 book Social choice […]

This self reinforcement is a key mechanism to understand the different effects caused by the media on their audience, since people are motivated to maintain a positive image of themselves by […]
