McNamara Fallacy

The McNamara Fallacy refers to judging the success or value of a project or effort solely based on measurable quantities, such as numbers or data, while ignoring qualitative factors like human experience, context, or moral considerations. Named after Robert McNamara, a U.S. government official, it highlights how relying only on easily quantifiable metrics can lead to incomplete or misguided conclusions, overlooking important aspects that are harder to measure but equally essential for understanding the full impact or validity of a situation.
