This document discusses the concept of "effectual reasoning" as an alternative form of rationality used by entrepreneurs. It outlines 3 key principles of effectual reasoning:
1) The affordable loss principle - entrepreneurs focus on reaching the market with minimum resources rather than expected return.
2) The strategic partnerships principle - entrepreneurs build partnerships from the start rather than doing competitive analyses.
3) Leveraging contingencies - entrepreneurs leverage unexpected events and surprises that come their way rather than relying solely on pre-existing knowledge. Effectual reasoning focuses on imagination and action over elaborate planning.
