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.     

Employment and Urban Native Canadians

Designed to measure differences in employment issues between a selected native Canadian Indian group and a non-native comparison group in Toronto, the study demonstrated that given similar circumstances for comparison, Native Canadians are less formally educated and skill trained than are non-natives of comparable age, sex, and education. Respondents under the age of 25 and over 50 earned substantially less than respondents within that age range.     

Confidence and Uncertainty in Judgmental Forecasting: Differential Effects of Scenario Presentation

Multiple scenario analysis is used by many organizations for long-term planning, in part because the development of more than one scenario of the future is thought to prevent overconfidence in any one specific forecast. The present study attempts to clarify some of the questions concerning the cognitive effects of scenario presentation by distinguishing between confidence and subjective uncertainty. It examined the impact of different types of scenario information on confidence ratings, credible intervals, and features of forecast series. Subjects (N=186) read either one, two, or no scenario(s) describing potential changes in the level of a stimulus variable, then made forecasts of that variable over the next fifty years. Reading any type of scenario information increased confidence in forecasts; there was no reduction in confidence due to presentation of multiple conflicting scenarios, compared to presentation of only one scenario. Differences in number and in type of scenarios presented did, however, affect subjective uncertainty.
