See Weick, 1979, pp 134. ""How can I/we know what I/we/they think/feel/want until I/we/they see/hear what I/we/they say/do."" This is in the enactment-selection-retention format (sequenced as actor-retention (believing) - selection (seeing) - enactment. The simple form of this statement approximates the ways in which people act: ""I'll see it when I believe it.""

Note: Enactment is to organizing as variation is to natural selection. (The evolutionary algorithm being variation-selection-retention).
