amplification
What It Means
Amplification occurs when an AI system makes existing biases or disparities worse than they were in the original data. Instead of just reflecting unfair patterns from the real world, the AI actually magnifies these differences, creating outcomes that are more skewed than what humans were already doing.
Why Chief AI Officers Care
Amplification creates serious legal and reputational risks because your AI system could be demonstrably making discrimination worse, not just perpetuating existing problems. This makes it much harder to defend in court or to regulators, and can damage customer trust and brand reputation when the amplified bias becomes visible in business outcomes.
Real-World Example
A hiring AI trained on historical data where 30% of engineering hires were women might end up recommending women for only 15% of positions, even when qualified female candidates are available. The system didn't just reflect the existing gender imbalance—it made it significantly worse by being overly conservative in recommending female candidates.
Common Confusion
People often think any AI bias is amplification, but amplification specifically means the AI is making disparities worse than they were in the training data. An AI that perfectly mirrors existing human bias is biased, but not amplifying—amplification only occurs when the AI's outputs show greater disparity than the original human decisions it learned from.

"[an act of amplifying, which is] to make larger or greater (as in amount, importance, or intensity)."Source: Merriam-Webster_amplify
"Let [construct space] 𝑌 ′ and [prediction space] 𝑌ˆ be categorical. Then, a model exhibits disparity amplification if 𝑑tv (𝑌ˆ |𝑍=0,𝑌ˆ |𝑍=1) > 𝑑tv (𝑌 ′ |𝑍=0,𝑌 ′ |𝑍=1). dtv is the total variation distance defined as follows. Let 𝑌0 and 𝑌1 be categorical random variables with finite supports Y0 and Y1. Then, the total variation distance between 𝑌0 and 𝑌1 is 𝑑tv (𝑌0,𝑌1) = 12 Σ︁ 𝑦∈Y0∪Y1 Pr[𝑌0=𝑦] − Pr[𝑌1=𝑦] . In the special case where 𝑌0,𝑌1 ∈ {0, 1}, the total variation distance can also be expressed as | Pr[𝑌0=1] − Pr[𝑌1=1] |."Source: yeom_avoiding_2021
