"Praise shows what the possibilities are. Criticism shows what the possibilities are not." Kim Malone Scott
Be warned! Your people will move in the direction of the feedback and guidance they receive. If this guidance is critical then most people will move in a direction to ensure they don't get feedback like this again. Our brains' limited attention spans and aversion to loss hardwire us to do whatever we can to 'make the pain go away'.
Hardly a strategy for greatness!
New research reveals high performance is rarely achieved by correcting our weaknesses.
Rather high performance is a function of using our strengths on a daily basis.
Hence Kim's quote above. Praise focuses are attention and subsequent efforts on what is working and will promote more of that behaviour. Remarkably Gallup found positive attention (praise) is 30X more likely to drive engagement than negative attention (criticism). And as we all know engagement is a precursor to high performance.
