A structure of form words used by Theorist A can generate thought trials that could not be imagined by Theorist B, who thinks using a different structure. To insert the ideas of one struc ture into the forms of another structure is to increase both the heterogeneity among thought trials and the probability of an original solution. Weick and Orton (1986) experimented with this tactic using content from Staw, Sandelands, and Dutton's (1981) article on threat-rigidity cycles and found that a variety of sensible assertions could be made for topics totally different from those involving stress. It is unlikely that similar assertions would have been made by people working within those topics.
