A dictator learns that a professor has written a 750-page dissertation exposing his regime. The dictator's agents offer the professor $25,000 to buy the manuscript. The professor refuses. The dictator then orders the professor kidnapped and killed. But the dissertation has already been submitted to the university. After the professor's disappearance, the university awards the doctorate posthumously and publishes the dissertation, which becomes a bestseller. From a behavioral analysis perspective, what does the dictator's decision to proceed with the kidnapping — after the manuscript was already submitted and therefore beyond his ability to suppress — reveal about his primary motivation?
