Behavioural skills - cognitive bias.

Default bias includes the tendencies to:

  • Favour inaction over action; and
  • Continue to support previously made decisions.

Examples include the substantial differences between the proportions of people making the identical choices, depending whether the choice is structured as an "opt in" or "opt out".

Opt out policy design results in signficantly higher participation rates, because of the default bias to take no action.

Default bias is also known as status quo bias.
