decision making

You perform differently when the task requires effort.

The effort-accuracy trade-off shows that you adjust your cognitive effort based on how much accuracy you believe the task requires.

When you perceive a task as 'low stakes,' you automatically shift to lower-effort processing strategies. You rarely use your full cognitive capacity unless the environment forces you to do so.

You are a cognitive miser by default, not by choice.
