How to say "bias" in Japanese

Choosing the right word
  • 偏見へんけんJLPT N1approx.Common
    nounBias in the sense of prejudice: an unfair, distorted view of people or groups, formed without fair examination. Use it for prejudice against a person, group, or idea.
    彼女かのじょは科学かがくにおける性的せいてき偏見へんけんについて書かいた。↗
    She wrote on gender bias in science.
  • 僻みひがみCommon
    nounBias as a warped, resentful outlook — a twisted way of seeing things that shades into jealousy. For neutral or technical 'bias' it is seldom the word you want.
  • 偏りかたよりCommon
    nounBias as skew or imbalance: unevenness in a distribution, sample, or set of figures, so it suits statistical and technical contexts. It names the uneven state itself rather than a prejudiced attitude.
  • 傾きかたむきCommon
    nounReally a tilt or a tendency: it covers 'bias' only as a leaning of opinion or a cast of mind, and for most senses of 'bias' it is not the word you want.

Use 偏見 for bias as prejudice against people or groups, 「僻み」 for a warped, resentful outlook, 「偏り」 for statistical or distributional skew, and 「傾き」 mainly for tendency or tilt rather than bias.
