It is absolutely something that can be taught, practised, and developed. The article expressed a certain backbiting suspicion that I think characterizes the intellectual view of charismatic people, and it focused on the charisma of authoritarian leaders, but oddly doesn't mention super-charismatics like Bill Clinton or Barack Obama, Oprah Winfrey, and other progressive persuaders. Ultimately, I think this type of critical view of charisma demoralizes people away from believing anything strongly enough to follow a leader in pursuit of their interests, which seems like an altogether more insidious effect than the posturing of a leader could be.
