Studies have shown that psychopaths are, on average, more successful as CEOs than non-psychopaths. This certainly seems like a good example of that (his reaction and behavior with the reporter were perfect!).
IIRC the book was written by the scientific wing of the Polish Resistance movement during authoritarian occupations of the 20th Century. Apparently, many of the people involved in sourcing the data (and, oh yeah, who had secretly diagnosed many of the Nazi/Communist leaders as psychopaths) were killed, when the first edition of the book was discovered in progress. And that first manuscript was destroyed, but the lead author wrote it again -- not once, but two more times -- and ultimately, had to wait for the fall of Communism in order to get it out of Poland. It was finally translated and published during the Bush administration, by New York liberals.
