Captain Kirk or Mr. Spock?
The brave but emotional fighter pilot or the ultra-logical but "cold fish" analyst?
After years of favoring Spock, I've concluded that I'm not wild about either one. There is more to life, if I may twist a phrase, than contained in Spock's logic and Kirk's embrace of the emotional can be more than off-putting.
The two extremes are helpful reminders that there is no single leadership style that is best. The most effective leaders use a multitude of approaches depending upon the occasion. Sometimes, it is time to be collegial and other times a more formalistic or even autocratic approach is required. That versatility, however, must be anchored to a solid core of values or else versatility will quickly sink into rank opportunism.
As for fiction, Kirk and Spock are pretty boring compared to Jack Aubrey and Stephen Maturin.
