Decision & ChoiceBias #97

Automation Bias

We trust automated systems over human judgment.

The tendency to favour automated decision-making systems or algorithmic suggestions over non-automated human judgment even when the automation is imperfect.

Why it matters: Explains accidents in aviation medicine and self-driving cars where humans over-relied on automation.

Watch for

Deferring to automated recommendations without critical evaluation.

Try this

Treat automation as one input not an authority and test its outputs regularly.

Real-world example

A pilot follows an autopilot recommendation that contradicts their own assessment because the system must be correct.

First described in 2000

Psychological mechanism

Trust transfer and effort reduction. Automated systems are perceived as objective and error-free reducing the cognitive effort of evaluation. Humans also treat machines as authority figures.
