3. Questions that identify omitted information

• remind yourself that regardless of how attractive the reasons supporting a particular decision or opinion may initially seem, you need to take another look in search of omitted information.

• ask questions to help decide what additional information you need, and then ask questions designed to reveal that information.

• use many kinds of questions to identify relevant omitted infor- mation. Some questions you have already learned to ask will highlight such information.

4. But we need to know the numbers

• Try to develop the habit of being sensitive to the need for specific numbers whenever you read or see an argument that uses concepts like “greater than,” “more than,” faster,” “thinner,” “after” (how long after?), and any other concept that comes in sizes and scope.

5. The importance of the negative view

• Remember to ask, "What are the potential long-term negative effects of the action?" when considering omitted information.
