Where am I coming from?The Decision-Centric Worldview The only way that individuals can purposely exercise any control over their lives, their careers, or their surroundings it through their decision making. -- Ralph Keeney In a few hundred years, when the history of our time will be written from a long-term perspective, it is likely that the most important event historians will see is not technology, not the Internet, not e-commerce. It is an unprecedented change in the human condition. For the first time -- literally -- substantial and rapidly growing numbers of people have choices. For the first time, they will have to manage themselves. And society is totally unprepared for it. -- Peter Drucker © 2003-2010 Patrick S. Noonan - Emory University

Telling us to obey instinct is like telling us to obey "people." People say different things: so do instincts. Our instincts are at war… Each instinct, if you listen to it, will claim to be gratified at the expense of the rest. -- C. S. Lewis © 2003-2010 Patrick S. Noonan - Emory University

“What are some limits on my intuition?” • Experiments reveal important insights about the mental operating system (OS) of humans • Intuition & expertise have important roles… • …but also some limitations. • The human OS displays systematic weaknesses… • … but that’s actually good news! The brain is a machine assembled to survive. -- Edward O. Wilson This view of mind suggests that the liberal arts are those modes of reasoning needed in civilized society that are not innate because they had no survival value on the savanna. -- David S. Moore © 2003-2010 Patrick S. Noonan - Emory University

Russo & Schoemaker’s “Decision Traps” • Source: Decision Traps, Russo & Schoemaker (1989) • Most common organizational decision-making dysfunctions: 1. Plunging In 2. Frame Blindness 3. Lack of Frame Control 4. Overconfidence 5. Shortsighted Shortcuts 6. Shooting from the Hip 7. Group Failure 8. Fooling oneself about Feedback 9. Not Keeping Track 10. Failure to Audit the Decision Process © 2003-2010 Patrick S. Noonan - Emory University
Decision Trap #1: Plunging In • Source: Decision Traps, Russo & Schoemaker (1989) • Behavior: • Starting the analysis & decision making before thinking about the objectives, the context and the most appropriate decision process • Consequence: • Inefficient decision making, often sloppy and misdirected • Solution: • Devote careful thought to the metadecisions first. © 2003-2010 Patrick S. Noonan - Emory University
The Metadecisions: “How Should I Decide?” • Source: Decision Traps, Russo & Schoemaker (1989) • There are very important decisions you can make about the decision processes you use • Higher-order decisions make you think about the nature of what you’re trying to decide • Examples: • What’s the main difficulty in this issue? • In general, how should decisions like this one be made (participants, style, time allotted, etc.)? • Is this decision linked to others, i.e. does it materially affect other decisions, or is it affected by others? © 2003-2010 Patrick S. Noonan - Emory University
More Metadecision Questions The most basic of all decisions is who shall decide. This is easily lost sight of in discussions that proceed directly to the merits of particular issues, as if they could be judged from a unitary, of God's eye, viewpoint. A more human perspective must recognize the respective advantages and disadvantages of different decision making processes, include their widely varying costs of knowledge, which is a central consideration often overlooked in analyses which proceed as if knowledge were either complete, costless, or of a 'given' quantity. -- Thomas Sowell • Source: Decision Traps, Russo & Schoemaker (1989) Must this decision actually be made? Should I make the decision along, with others, or delegate it? How much time should it take? Must the decision be made now? If not, when should it be made? Are the constraints and deadlines real? Should I move sequentially in the process, or back and forth? © 2003-2010 Patrick S. Noonan - Emory University
Still MoreMetadecision Questions • Source: Decision Traps, Russo & Schoemaker (1989) What’s a good balance of effort, i.e. where should I concentrate my time & resources? Is there some feedback or history from related experiences to draw upon? What are my own capabilities, biases & limitations in dealing with an issue like this? Do I need to bring in others’ points of view? What other points of view might be helpful? How would an admired, more experienced decision maker handle this issue? © 2003-2010 Patrick S. Noonan - Emory University
Discussion Questions • How much thinking or discussion does your organization apply to the meta-decisions, the decisions about how to decide? • How would you describe your organization’s typical “balance of effort” in tackling important decisions? © 2003-2010 Patrick S. Noonan - Emory University
