The same quotes in an easier to read format, and I agree with them:
"Old Assumption
- Most accidents are caused by operator error. Rewarding safe behaviour and punishing unsafe behaviours will eliminate or reduce accidents significantly.
New Assumption
- Operator error is a product of the environment in which it occurs. To reduce operator "error" we must change the environment in which the operator works.
---
Old Assumption
- Major accidents occur from the chance simultaneous occurrence of random events.
New Assumption
- Systems will tend to migrate toward states of higher risk. Such migration is predictable and can be prevented by appropriate system design or detected during operations using leading indicators of increasing risk."
Just a day ago, user Gibbon1 also posted a link to a talk by the author of that book:
