Being a knowledge catalyst means taking the time to add value to your knowledge. One way is to simplify what you know. Make your work human understandable. Speak in non-geek terms. If experts do not do this they will become surrounded by less informed people over time. This has become evident over the course of the current SARS-CoV-2 pandemic, now in its third year. We seem to be collectively getting more stupid. People are voting for bombastic populists and supporting policies that make all of us poorer or less free to pursue our goals.
One way out of this mess is to make our social networks, and our society, smarter. Leadership today is helping our networks make better decisions.
