**Internal Strife** is the catchall theme connecting many danger flags. The chapter draws on the CIA's 1963 Counterintelligence Interrogation manual, which classified people into nine personality categories. The ones relevant to internal strife are the categories where people fight themselves — guilt-ridden characters, those wrecked by success, greedy/demanding types, and rebellious exceptions. **The core insight**: "The thoughts they had were the parents of the actions they did; their feelings were parents of their thoughts: it was the unseen and spiritual in them that determined the outward and actual." (Carlyle) Outward behavior — greed, guilt, self-sabotage, rebelliousness — is driven by unseen internal conflicts. **The nine CIA categories**: 1. Orderly-obstinate 2. Optimistic 3. Greedy and demanding 4. Anxious and self-centered 5. Guilt-ridden 6. Wrecked by success 7. Schizoid (magical-thinking, ungrounded) 8. The Exception 9. Average or Normal The five categories of internal strife are #3, #4, #5, #6, and #8 — people whose internal conflicts drive them toward destructive external behaviors.
