  • Prof. Dinnar–

    Hello, my name is Rob Toth, and I’m an editor with the Wall Street Journal, overseeing the paper’s special reports on small business. I’d like to ask about your research into the mistakes that entrepreneurs make when they negotiate. Why are the negatives that you identify (self-centered, overly optimistic, putting too much emphasis on short-term winning, quickly compromising, working alone, haggling, relying on intuition and denying emotions) so prevalent among entrepreneurs versus businesspeople as a whole, or any group of people as a whole? What are the particular characteristics that push entrepreneurs toward these mistakes?

    Thank you for your time!

    All the best,
