Nasty, abusive, fiery. The adjectives you presume are usually not pleasant when you type the words 'fast' and 'bowler' next to each other. Some even label them as 'dumb', or people with short fuses. When it comes to the captaincy, the tribe is always ignored, and a batter is usually favoured to do the job as they are perceived to be calmer, more intelligent.
A more logical explanation about why fast bowlers are usually not made captains is, they already have so much on their plate physically. Adding the responsibility of field placements, rotation of bowlers, choice of roller, addressing the media before or after a win or loss etc, becomes a needless distraction.
