He has served on the board of directors for multiple companies, most prominently Max & Erma's Restaurant, Inc., Abercrombie & Fitch, and Worthington Foods.
In 1999, Worthington Foods discussed a possible merger with the Kellogg Company where Blackwell served as a board member.
Two of the shareholders were an employee of Roger's consulting firm and her husband, who bought additional shares in the IRA accounts.
Blackwell maintains his innocence, believing his policy of not commenting about board meetings was the appropriate response to people who asked about the company.
Today, Blackwell is a frequent speaker at corporate seminars and university classes on behavioral economics, marketing, and ethics.
