Kim Scott

Kim Scott authored 'Radical Candor,' the most-referenced book on Lenny's Podcast. She was a CEO coach at Dropbox, Qualtrics, and Twitter, a faculty member at Apple University, and led AdSense, YouTube, and DoubleClick teams at Google. Their core argument: The real failure is not firing too fast or too slow -- it is never giving honest feedback in the first place. The evidence is specific: Scott's boss at Google told her 'When you say um every third word, it makes you sound stupid' -- this direct feedback led Scott to work with a speech coach and changed her career trajectory. Furthermore, a manager avoids telling an engineer about missed deadlines, works around the problem for six months, then fires the person -- who is shocked because they were never told. In Kim Scott's own words: "By far and away the most common problem occurs when we do remember to show that we care personally, but we're so worried about not hurting someone's feelings that we fail to tell them something they'd be better off knowing in the long run. And that is what I call ruinous empathy." (Defining the most common leadership failure.)

Author of Radical Candor (1M+ copies sold, 23 languages), former CEO coach at Dropbox, Qualtrics, Twitter, and faculty at Apple University; led AdSense, YouTube, and DoubleClick teams at Google Their core argument: Radical candor requires caring personally AND challenging directly -- they are not in tension but two dimensions of the same framework. The evidence is specific: Sheryl Sandberg telling Kim Scott 'when you say um, it makes you sound stupid' -- blunt feedback that landed as a gift because of the deep care relationship. Furthermore, kim's father diagnosed with cancer -- Sandberg told her to go home, team would write coverage plan, establishing care before any challenging feedback. In Kim Scott's own words: "Radical Candor is just what happens when you care personally and challenge directly at the same time." (Core definition of radical candor as a 2x2 framework.)
