Summary

Entrepreneurs prefer effectual reasoning over causal reasoning in the early stages of a new venture, which is a creative process that begins with three categories of means: Who they are, What they know, and Whom they know. Effectual reasoning focuses on affordable loss, strategic partnerships, and leveraging contingencies, while causal reasoning focuses on expected return, competitive analyses, and exploiting pre-existing knowledge. Effectual reasoning involves recognizing that the future can be shaped by human action, and that failure can be minimized by allowing it to occur earlier and with less investment.
