In this chapter, the author of the book explains why people are tend to blame themselves for technological problems. Even though the problems might be caused by bad design, people are always mad at themselves and they feel like stupid. Later he explains the seven stage of action:
How easily Can One:
Determine the function of the device?
Tell what actions are possible?
Determine mapping from intention to physical movement ?
Perform the action?
Tell if system is in Desired State?
Determine mapping from System state to interpretation?
Tell what state the system is in?
