Editing Rumor (section)

==''A Psychology of Rumor'' (1944)==
"A Psychology of Rumor" was published by {{ill|Robert H. Knapp|fr}} in 1944, in which he reports on his analysis of over one thousand rumors during World War II that were printed in the ''[[Boston Herald]]'''s "[[Boston Herald Rumor Clinic|Rumor Clinic]]" Column. He defines rumor as 
<blockquote>''
a proposition for belief of topical reference disseminated without official verification''. So formidably defined, rumor is but a special case of informal social communications, including myth, legend, and current humor. From myth and legend it is distinguished by its emphasis on the topical. Where humor is designed to provoke laughter, rumor begs for belief.<ref>p.22</ref>''

Knapp identified three basic characteristics that apply to rumor: 
# they're transmitted by word of mouth; 
# they provide "information" about a "person, happening, or condition"; and 
# they express and gratify "the emotional needs of the community." 
Crucial to this definition and its characteristics is the emphasis on transmission (word of mouth, which then was heard and reported in the newspaper); on content ("topical" means that it can somehow be distinguished from trivial and private subjects—its domain is public issues); and on reception ("emotional needs of the community" suggests that though it is received by an individual from an individual, it is not comprehended in individual but community or social terms).

Based on his study of the newspaper column, Knapp divided those rumors into three types:
# Pipe dream rumors: reflect public desires and wished-for outcomes (e.g. Japan's oil reserves were low and thus World War II would soon end).
# Bogie or fear rumors reflect feared outcomes (e.g. An enemy surprise attack is imminent).
# Wedge-driving rumors intend to undermine group loyalty or interpersonal relations (e.g. American Catholics were seeking to avoid the draft; German-Americans, Italian-Americans, Japanese-Americans were not loyal to the American side).

Knapp also found that negative rumors were more likely to be disseminated than positive rumors. These types also differentiate between positive (pipe dream) and negative (bogie and wedge-driving) rumors.
