Perceptions of Brainstorming in Groups: The Quality Over Quantity Hypothesis

Our research focused on the implicit beliefs of potential brainstormers about the possible outcomes of brainstorming. We conducted four studies to assess the relative importance of quality and quantity as goals of brainstorming. In Study 1, we found evidence for a quality over quantity hypothesis: participants indicated that it was more important to produce creative, original, and high quality ideas than to generate a large number of ideas. In Studies 2 and 3, participants displayed support for the quality over quantity hypothesis by showing in group favoritism for a quality dimension but not a quantity dimension. Study 4 showed that participants believed brain-storming would enhance the quality of others' ideas more than one's own ideas, but they did not display a similar bias about idea quantity.     

Integrating Qualitative and Quantitative Research Methods: A Research Model

A historical antagonism between proponents of qualitative methods and quantitative methods has prevented recognition of the benefits to be gained by employing both methods (that is, a multi-method approach) during the same study or program of studies. Increasingly, family therapy researchers have begun to recognize the value of a multi-method approach in bridging the current gaps among theory, research, and practice. However, current writings have yet to move beyond the discussion stage. This article proposes a bidirectional continuum that includes both qualitative and quantitative methods. An ethnographic content analysis approach is presented to illustrate the procedural stages of this continuum. The article ends with a discussion of the challenges in carrying out a bidirectional, multi-method approach and the potential contributions that an integrative research methodology will give both researchers and clinicians.     

BIORHYTHMIC CYCLES AND THE INCIDENCE OF INDUSTRIAL ACCIDENTS

The biorhythm theory of accident explanation that has been increasingly popularized in the business press was empirically examined. The data set consisted of municipal employees adjudged to be at fault in 150 work-related vehicular accidents, and municipal employees involved in 210 on-the-job accidents resulting in workmen's compensation claims. Each accident case was analyzed to determine whether or not the accident occurred on a biorhythmically critical day. The results showed no systematic relationship between critical days and accident occurrences for these data groups. The data were also systematically evaluated for the existence of non-biorhythmic cycles. The results of this analysis showed that no useful level of association existed for any cycle. It was concluded that, while other groups or events may exhibit measurable cyclical patterns, it seems likely that the relationships are more complex than a simple association such as that posited on the basis of biorhythm theory.
