If you’re working to improve your leadership capability, what exactly should you be trying to develop? The experience of the 2020 pandemic offers a powerful lesson: A critical skill a leader must bring to the table is the ability to figure out what kind of thinking is required to address a given challenge. Bring the wrong kind of thinking to a problem and you’ll be left fruitlessly analyzing scientific data when what’s desperately needed is a values-informed judgment call. Or, just as bad, you’ll trust your instincts on a matter where a straightforward data analysis would expose how off-base your understanding is.
