The cognitive bias where one assumes that their preferred measures of efficiency are simply "efficiency"—neutral, objective, universal—while dismissing other measures as irrelevant or biased. Efficiency Bias is what makes businesspeople assume that profit measures efficiency, that what's good for the bottom line is what works. It's what makes policymakers assume that cost-benefit analysis captures all relevant values. Efficiency Bias treats one construction of efficiency as the construction, one perspective as the perspective. It's the favorite bias of those who benefit from current definitions of efficiency, who don't want to ask "efficient for whom?"
Example: "He presented the profit numbers as proof of efficiency. Efficiency Bias meant he never had to consider environmental costs, worker well-being, community impact. His measure was the measure; everything else was secondary. When she pointed out what was excluded, he dismissed her concerns as 'not relevant to efficiency.' The bias was invisible to him, which is how it worked."
