Attention & Focus

Cognitive Bias

Systematic thinking errors shape how users perceive and decide.

Takeaways

  1. 1

    Users do not always choose the most rational option.

  2. 2

    Social proof and defaults strongly influence behavior.

  3. 3

    Design for observed patterns, then validate with diverse participants.

Origins

Cognitive biases are predictable shortcuts in human judgment. They help people act quickly, but they also create blind spots that interfaces can either exploit or protect against.

Ethical product design acknowledges these tendencies and makes important outcomes transparent rather than hidden.

Design Applications

  • Make consequences of irreversible actions explicit.
  • Use defaults that benefit most users without trapping others.
  • Test flows with people outside your team’s assumptions.
