What it is

Algorithm aversion describes reduced willingness to use algorithmic judgment relative to a human alternative. In foundational experiments, observing an algorithm make errors reduced its use despite its superior overall performance. (Dietvorst et al., 2015)

In everyday language

People may lose confidence in a computerized recommendation after seeing it make a mistake, while remaining more forgiving of human mistakes.

What it isn't

Rejecting a system is not necessarily irrational. Its performance, suitability, transparency, and the costs of its errors may provide good reasons not to use it.

An example

Hypothetical example: a person abandons a forecasting tool after one visible error and returns to a method that has a worse record across many predictions.

Key features

  • Concerns preference for a decision source
  • Can follow observing an algorithm's mistakes
  • Requires a meaningful comparison of performance

How it relates to synthetic imprinting

Synthetic experiences may influence trust in either direction. This concept helps avoid assuming that realistic or fluent AI output always increases reliance.

Research context

Dietvorst, Simmons, and Massey demonstrated algorithm aversion in forecasting studies. The finding is context-dependent; other experiments show a preference for algorithmic advice. (Dietvorst et al., 2015)

Sources and what they support

  1. Algorithm aversion: People erroneously avoid algorithms after seeing them err. — Berkeley J. Dietvorst, Joseph P. Simmons, Cade Massey (2015). Journal of Experimental Psychology: General.

    Peer-reviewed research. Examines avoidance of algorithmic forecasts after observing errors, even when the algorithm outperforms a human alternative.

Revision history

These are retained versions of the opening definition. Revision dates describe editorial work, not independent scientific validation.

  1. Version 1.4 · Current

    Added claim-level citations and a separate assessment of evidence support. The opening definition is unchanged.

    Read this version’s definition
    Algorithm aversion is a reluctance to use algorithmic advice, sometimes even when it performs better than an available human alternative. Research has examined how seeing an algorithm make mistakes changes willingness to rely on it. The term does not make every rejection irrational: a system's suitability, performance, and consequences of error still matter.
  2. Version 1.3

    Expanded the opening definition; added explicit boundaries, source context, related-term cards, and linked editorial attribution.
