1. Errors in Reasoning
Goal: Identify common types of errors and avoid them.
Many of these come up in the WASI
A major reason for taking it is so that you can self-identify errors that you tend to make
Many points are lost on tests/homeworks in school come from errors in reasoning, not from lack of knowledge or skills.
You can train yourself to reduce making this sort of mistake.
Comprehension in reading is a major factor to success. Proper comprehension of technical material requires careful reading, and often re-reading. There is no such thing as speed reading with comprehension.

2. Types of Errors Lack of knowledge or skill
This isn’t our focus, and its often not the issue
Failure to observe and use all relevant facts of a problem
This might come from poor reading comprehension (which in turn often comes from rushing)
Failure to approach the problem in a systematic manner, skip steps or jump to conclusion
Failure to spell out relationships fully
Being sloppy or inaccurate – making “simple” mistake
Lack of confidence.
W&L Chapter II goes through several of the problems on the WASI

3. Error Types Checklist Inaccuracy in Reading Inaccuracy in Thinking
Weakness in Problem Analysis; Inactiveness
Lack of Perseverance

4. Myers-Briggs Type Indicator

For example, most introverts can operate in extrovert mode when needed.
Results can vary from test to test or day to day by several points.
Results are generally consistent, between “adjacent” types
Wikipedia has good articles for some types
