Present Bias
The tendency to overvalue immediate rewards relative to larger rewards available later.
How it is identified
Test: a smaller immediate reward is preferred to a larger delayed one, at a discount rate far above the market rate
Unit
qualitative
In depth
Present bias is the reason saving is hard: the cost is felt now and the benefit is decades away, and the immediate cost is weighted far more heavily than any spreadsheet justifies. It undermines every long-horizon plan, from retirement saving to leaving a compounding investment alone. The most effective countermeasures are structural rather than motivational — automatic deductions, SIPs on the salary date, and lock-in instruments all remove the decision from the moment of temptation. Its formal expression is hyperbolic discounting, which explains why the preference reverses as the reward approaches.
Worked example
₹5,000 a month diverted to a SIP is a visible monthly cost against a benefit thirty years away. Automating it on the salary date removes thirty years of monthly decisions, each of which would face the same bias.
