Harvard Business Review recently published an article on what leading Data Scientists actually do. Surprisingly enough, the key skill is communication, rather than experience with statistical models.
Aristotle argued that to persuade people, you need to use Ethos, Logos, and Pathos. Ethos establishes the credibility of the speaker, and Logos appeals to the reasoning used. Yet, both are useless without Pathos, the way to the heart of the audience. The Homo Data Scientistus generally falls in love with causal, data-driven reasoning when presenting their work. This is generally the right way to argue. But to evoke actions, Data Scientists need to tell stories.
