One of the riddles studied in philosophy is "in the land of the blind, the one eyed man is king". In such a place perhaps 50 percent of the people would not even know that sight existed, 40 percent would think one eye was required to see and maybe one percent would consider the concept of two eyed people (or more eyes). In other words the nature of the information can shape reality but that does not make it true (the inductive fallacy).
The recent rash of VC blog posts in response to Vivek Wadhwa's post on Tech Crunch about entrepreneurship being learned (discussed in my post here) demonstrates the VCs' need to study more philosophy. The VCs almost unanimously conclude that entrepreneurs are born. What they overlook is that their sample of entrepreneurs is almost entirely people who make funding requests to VCs (the one percent). Many entrepreneurs never use other people's money (OPM) and those that use outside financing typically go to banks, factors and leasing companies. In other words the VCs are assuming that their data is representative of all entrepreneurs and in fact it is not. They appear to be overlooking all the entrepreneurs who never go to VCs. Entrepreneurship can be learned :)
