Present Bias
temporal discounting · hyperbolic discounting
Overweighting what is close in time. It makes a small reward now beat a much larger one later, and it is the mechanism behind almost every abandoned long-term plan.
In practice
The process document saves twenty hours over the next year. The billable hour pays today. The document keeps not getting written, and every individual day the choice was reasonable.
The common mistake
Treating it as a discipline problem. The preference reverses as the moment approaches, so decisions made in advance and made costly to reverse work better than resolve does.
Present bias is the tendency to weight immediate outcomes far more heavily than future ones, well beyond what any consistent rate of discounting would produce.
The inconsistency
Choosing between $100 today and $110 in a week, most people take the $100. Choosing between $100 in a year and $110 in a year and a week, most take the $110 — the same week's wait, the same extra $10, the opposite answer.
The difference is that one option is available now. Immediacy gets a premium that has nothing to do with the time interval, which is why preferences reverse as the near option approaches.
This is what makes plans fail rather than never get made. The plan is made at a distance, where the future is weighted normally. The choice arrives up close, where it is not, and the person who made the plan is outvoted by the person living in the moment it applies to.
What it explains
Most persistent gaps between intention and behavior. Training plans, saving, the difficult conversation, the work with delayed payoff. In business it explains why building leverage gets deferred: the billable hour pays today and the process document pays over two years.
It is the mechanism underneath proxy work — the comfortable task returns its reward immediately, and the uncomfortable one returns it later.
What helps
Commitment in advance. Decide while the choice is still distant and make the decision expensive to reverse. Standing appointments, automatic transfers, scheduled blocks, a commitment made to someone else.
Make the future concrete. Present bias feeds on the future being abstract. A specific figure and a specific date compete better than "later".
Move the immediate reward. Rather than fighting the preference, attach something immediate to the behavior you want, and add friction to the one you do not.
Shorten the gap. Anything that brings the payoff closer works with the bias instead of against it — which is why weekly targets outperform annual ones for almost everyone. See compounding.

What is present bias?
The tendency to weight immediate rewards disproportionately compared to future ones, in a way that causes preferences to reverse as a delayed option becomes immediately available.
How does present bias differ from simple impatience?
Consistent impatience would discount any delay at the same rate. Present bias applies an extra premium specifically to what is available now, which is why the same trade-off is judged differently up close.
How do you counteract present bias?
Commit in advance while the choice is still distant, make future outcomes concrete and dated, attach immediate rewards to the behavior you want, and shorten the gap between action and payoff.
