Wc. Rowatt et al., PERCEPTIONS OF BRAINSTORMING IN GROUPS - THE QUALITY OVER QUANTITY HYPOTHESIS, The Journal of creative behavior, 31(2), 1997, pp. 131-150
Our research focused on the implicit beliefs of potential brainstormer
s about the possible outcomes of brainstorming. We conducted four stud
ies to assess the relative importance of quality and quantity as goals
of brainstorming. In Study 1, we found evidence for a quality over qu
antity hypothesis: participants indicated that it was more important t
o produce creative, original, and high quality ideas than to generate
a large number of ideas. In Studies 2 and 3, participants displayed su
pport for the quality over quantity hypothesis by showing in group fav
oritism for a quality dimension but not a quantity dimension. Study 4
showed that participants believed brainstorming would enhance the qual
ity of others' ideas more than one's own ideas, but they did not displ
ay a similar bias about idea quantity.
