A great way for executives to hone their communication skills is by having a coach listen in on their conversations and provide feedback. But given the increasing capability of AI-based tools to have meaningful conversations with people, researchers wondered whether AI-tools could be used as sparring partners and advisors to executives looking to improve their coaching and communication styles. To test this theory, researchers created a tool, powered by GPT-4, and ran an experiment with 167 global executives in a range of industries. They found that AI-based coaching interventions can be an efficient, accessible, potent way to improve essential leadership capabilities.
