Ever wondered why our default is always to add, rarely to subtract? This episode unpacks compelling research demonstrating that people systematically overlook subtractive changes, consistently defaulting to additive transformations. We explore why this cognitive bias exists, leading us to accept adequate solutions while missing potentially superior alternatives. Discover the conditions that make us more likely to identify advantageous subtractive changes, including the presence of subtraction cues, multiple opportunities to recognise additive shortcomings, and operating under a lower cognitive load. Understand how this tendency impacts everything from overburdened schedules to institutional red tape and environmental challenges.
