Additive bias is the tendency to approach problem-solving by adding rather than subtracting elements. This cognitive bias often leads individuals to increase resources or components in a situation, even when a simpler solution could be achieved through reduction. Studies show that when faced with challenges, people frequently default to enhancing or complicating their strategies instead of simplifying or removing unnecessary parts.
In 2021, researcher Leidy Klotz conducted experiments where participants, given a problem, consistently opted to add elements instead of eliminating unnecessary ones, illustrating this bias. This is akin to a manager trying to improve a project by adding new features rather than streamlining existing ones to enhance efficiency.
To counteract additive bias, consciously evaluate whether a solution can be achieved through subtraction before considering further additions. Encouraging a mindset that values simplicity over complexity can help mitigate this bias.
