As Preda discovers through extensive research, the public was once much more skeptical. For investing to become accepted, a deep-seated prejudice against speculation had to be overcome, and Preda reveals that over the course of the eighteenth and nineteenth centuries groups associated with stock exchanges in New York, London, and Paris managed to redefine finance as a scientific pursuit grounded in observational technology. But Preda also notes that as the financial data in which they trafficked became ever more difficult to understand, charismatic speculators emerged whose manipulations of the market undermined the benefits of widespread investment. And so, Framing Finance ends with an eye on the future, proposing a system of public financial education to counter the irrational elements that still animate the appeal of finance.
