How Great Entrepreneurs Think

What distinguishes great entrepreneurs? Discussions of entrepreneurial psychology typically focus on creativity, tolerance for risk, and the desire for achievement—enviable traits that, unfortunately, are not very teachable. So Saras Sarasvathy, a professor at the University of Virginia's Darden School of Business, set out to determine how expert entrepreneurs think, with the goal of transferring that knowledge to aspiring founders. While still a graduate student at Carnegie Mellon, Sarasvathy—with the guidance of her thesis supervisor, the Nobel laureate Herbert Simon—embarked on an audacious project: to eavesdrop on the thinking of the country's most successful entrepreneurs as they grappled with business problems. She required that her subjects have at least 15 years of entrepreneurial experience, have started multiple companies—both successes and failures—and have taken at least one company public.

Sarasvathy identified 245 U.S. entrepreneurs who met her criteria, and 45 of them agreed to participate. (Responses from 27 appeared in her conclusions; the rest were reserved for subsequent studies. Thirty more helped shape the questionnaire.) Revenue at the subjects' companies—all run by the founders at that time—ranged from $200 million to $6.5 billion, in industries as diverse as toys and railroads. Sarasvathy met personally with all of her subjects, including such luminaries as Dennis Bakke, founder of energy giant AES; Earl Bakken of Medtronic; and T.J. Rodgers of Cypress Semiconductor. She presented each with a case study about a hypothetical start-up and 10 decisions that the founder of such a company would have to make in building the venture. Then she switched on a tape recorder and let the entrepreneur talk through the problems for two hours. Sarasvathy later collaborated with Stuart Read, of the IMD business school in Switzerland, to conduct the same experiment with professional managers at large corporations—the likes of Nestlé, Philip Morris, and Shell. Sarasvathy and her colleagues are now extending their research to novice entrepreneurs and both novice and experienced professional investors.

Sarasvathy concluded that master entrepreneurs rely on what she calls effectual reasoning. Brilliant improvisers, the entrepreneurs don't start out with concrete goals. Instead, they constantly assess how to use their personal strengths and whatever resources they have at hand to develop goals on the fly, while creatively reacting to contingencies. By contrast, corporate executives—those in the study group were also enormously successful in their chosen field—use causal reasoning. They set a goal and diligently seek the best ways to achieve it. Early indications suggest the rookie company founders are spread all across the effectual-to-causal scale. But those who grew up around family businesses will more likely swing effectual, while those with M.B.A.'s display a causal bent. Not surprisingly, angels and seasoned VCs think much more like expert entrepreneurs than do novice investors.

The following is a summary of some of the study's conclusions, illustrated with excerpts from the interviews. Understanding the entrepreneurs' comments requires familiarity with what they were evaluating. The case study and questions are too long to reproduce here. But briefly: Subjects were asked to imagine themselves as the founder of a start-up that had developed a computer game simulating the experience of launching a company. The game and ancillary materials were described as tools for teaching entrepreneurship. Subjects responded to questions about potential customers, competitors, pricing, marketing strategies, growth opportunities, and related issues. (The full case study and questions can be found here.)

Quotes have been edited for length, though we wish we had room to run them in their entirety. Sarasvathy remained almost silent throughout, forcing the founders to answer their own questions and externalize their thinking in the process. The transcripts, riddled with "ums" and "ers," doublings-back on assumptions, and references to personal rules of thumb, read like verbal MRIs of the entrepreneurial brain in action.

Do the doable, then push it

Sarasvathy likes to compare expert entrepreneurs to Iron Chefs: at their best when presented with an assortment of motley ingredients and challenged to whip up whatever dish expediency and imagination suggest. Corporate leaders, by contrast, decide they are going to make Swedish meatballs. They then proceed to shop, measure, mix, and cook Swedish meatballs in the most efficient, cost-effective manner possible.

That is not to say entrepreneurs don't have goals, only that those goals are broad and—like luggage—may shift during flight. Rather than meticulously segment customers according to potential return, they itch to get to market as quickly and cheaply as possible, a principle Sarasvathy calls affordable loss. Repeatedly, the entrepreneurs in her study expressed impatience with anything that smacked of extensive planning, particularly traditional market research. (Inc.'s own research backs this up. One survey of Inc. 500 CEOs found that 60 percent had not written business plans before launching their companies. Just 12 percent had done market research.)

When asked what kind of market research they would conduct for their hypothetical start-up, most of Sarasvathy's subjects responded with variations on the following:

"OK, I need to know which of their various groups of students, trainees, and individuals would be most interested so I can target the audience a little bit more. What other information...I've never done consumer marketing, so I don't really know. I think probably...I think mostly I'd just try to...I would...I wouldn't do all this, actually. I'd just go sell it. I don't believe in market research. Somebody once told me the only thing you need is a customer. Instead of asking all the questions, I'd try and make some sales. I'd learn a lot, you know: which people, what were the obstacles, what were the questions, which prices work better. Even before I started production. So my market research would actually be hands-on actual selling."
