CONCEPT LESSON

Present bias

Giving disproportionate weight to immediate outcomes compared with later ones.

Why it matters

A plan made for the future can unravel when the immediate reward arrives. Recognising this pattern helps explain why intentions and actions sometimes diverge.

A worked example

You plan to save next month but choose a non-essential purchase today. An immediate reward can defeat a previously preferred longer-term plan.
