Status quo bias
An emotional bias in which a person, fearing regret, ends up taking no decision at all and keeps things as they are — closely linked to regret aversion.
In plain language
Sometimes the easiest decision is not to decide. Status quo bias is what happens when a person has second thoughts or wants to avoid regret, and so takes no decision at all, leaving things as they are.
The workbook links it closely to regret aversion bias: people avoid making decisions that lead to an action, out of fear the decision will turn out poorly.
Regret has two dimensions:
- Error of commission — regret over an action you took.
- Error of omission — regret over an action you could have taken.
Regret from commission is more intense than regret from omission. Doing nothing feels safer, so people prefer the status quo. The workbook adds that complexity — in understanding or in execution — can also lead to the status quo.
How it works
Classification. The workbook lists status quo bias among the emotional biases (Chapter 14, section 14.3.1), alongside loss aversion, stereotyping, overconfidence and endowment bias.
Why doing nothing wins:
| Error of commission | Error of omission | |
|---|---|---|
| What it is | Regret over what you did | Regret over what you could have done |
| Intensity | More intense | Less intense |
| Result | People avoid acting | People accept inaction |
The cure the workbook cites: a nudge. Richard Thaler showed that a simple nudge led employees to enrol in pension plans that had previously had poor enrolment only because of status quo bias. Changing how the choice is presented changed the outcome without forcing anyone.
In a portfolio, status quo bias shows up as an asset mix that is never reviewed, a lump sum left idle, or an unsuitable holding kept because selling it would be a decision.
A worked example
Illustrative figures. Rekha, 52, inherited ₹40 lakh three years ago. It still sits in a savings account earning 3%, while her adviser's recommended balanced portfolio was expected to earn around 9%.
Why no action? "If I invest and the market falls, I'll never forgive myself." That is fear of an error of commission. The cost of doing nothing is an error of omission, which feels milder — but it is not small:
| Year 1 income on ₹40 lakh | |
|---|---|
| Savings account at 3% | ₹1,20,000 |
| Portfolio at 9% (expected, not guaranteed) | ₹3,60,000 |
| Expected gap | ₹2,40,000 a year |
The adviser borrows Thaler's idea and changes the default. Instead of asking Rekha to pick a moment to invest, he proposes a plan that moves ₹5 lakh a month automatically for eight months (8 × ₹5 lakh = ₹40 lakh) unless she opts out. She no longer has to make a single, regret-laden decision. She stays in the plan.
Why NISM asks about it
Chapter 14 (Behavioural Finance), section 14.3.1, covers status quo bias with regret aversion, the commission/omission distinction and Thaler's pension-enrolment nudge. It is a natural question on classification (emotional bias) and on which type of regret is more intense.
Common exam traps
- Regret from commission is more intense than regret from omission. Reversing these is the classic trap.
- Status quo bias is an emotional bias, not a cognitive error.
- Its close relative is regret aversion, not anchoring. Anchoring is about relying on pre-existing information; status quo is about avoiding a decision.
- Complexity also causes it — not just fear of regret.
- The nudge example is Richard Thaler's (pension enrolment). Thaler is also the name behind mental accounting.
