A financial adviser tells two clients the exact same thing about the exact same fund.
To the first, she says: “The annual fee is just 1%.” He shrugs. One percent is nothing. He signs.
To the second, she says: “Over your investing lifetime, that fee will quietly take roughly a quarter of the returns you’d otherwise have kept.” He sits up. A quarter of his returns? He starts asking hard questions.
Both clients heard a true statement. Both statements describe the identical fee. The only thing that changed was the frame, and the frame changed the decision. That is the whole subject of this post: how the wording of a choice, and the first number attached to it, can steer you without your noticing.
Framing: same fact, different decision
The framing effect is one of the most robust findings in behavioural science. Present the same information two ways and people choose differently, even though nothing real has changed.
Watch a single commitment shift its weight as you reframe it:
- “Save 200 euros a month.” Sounds modest. Manageable. Maybe even a little unambitious.
- “Save 2,400 euros a year.” Same thing. Now it sounds like real money.
- “Set aside 72,000 euros over the next thirty years, before any growth.” Identical commitment. Now it sounds enormous, almost daunting.
Nothing about the plan changed across those three sentences. Only the unit changed, and with it the feeling, and with the feeling the decision. Marketers know this intimately. A subscription is “less than the price of a coffee a day,” never “440 euros a year.” A discount is shouted as money saved, never as money still spent. None of it is false. It is simply the flattering frame, placed where you will see it first.
The 1% fee is the most expensive example most people meet. Charged every year on your entire balance, it compounds into something far larger than it sounds, because the money skimmed off in fees also stops growing. “One percent” is the small frame. “About a quarter of your lifetime returns” is the honest frame. Same fee.
Anchoring: the tyranny of the first number
The second trick is even sneakier, because it works through numbers you would swear you ignored.
Anchoring is the tendency to lean on the first number you see and judge everything afterward relative to it, even when that first number is irrelevant. In experiments, people shown a clearly random high number before guessing an unrelated quantity guess higher than those shown a low one. The anchor was meaningless, and it moved them anyway.
In money, anchors are everywhere:
- A coat marked down from 300 euros to 180 feels like a steal. The 300 is the anchor. Whether 180 is actually a fair price for the coat never gets examined.
- You bought an investment at 50. It is now at 40. You decide to wait until it gets “back to 50” before selling, even though the market has no memory of your purchase price. The 50 is an anchor, and it is making the decision for you.
- The market hit a high last year. Now you are mentally waiting for it to return to that level before you feel safe. Last year’s peak is just a number, but it has become your reference point.
The purchase-price anchor is closely tied to the loss aversion from earlier in this series: clinging to “back to even” is anchoring on the price you paid and refusing to accept a loss relative to it.
When framing and anchoring join forces: sunk costs
The two biases combine into one of the most stubborn mistakes there is: the sunk cost fallacy.
A sunk cost is money, time, or effort you have already spent and cannot get back. Logically, it should have zero influence on what you do next, because it is gone either way. Emotionally, it dominates. You keep a failing investment because you paid more for it. You sit through a film you stopped enjoying because you bought the ticket. You pour more into a struggling project to justify what you already put in.
That is anchoring on a past number that no longer matters, dressed up by a frame that says quitting would “waste” what you spent. But the spending is already wasted or not, regardless of what you do now. The only sentence that cuts through it is this: knowing what I know today, would I choose this from scratch right now? If the answer is no, the money you already spent is not a reason to continue. It is just gone.
The defence is cheap and reusable
Unlike most biases, framing and anchoring have a defence that is genuinely easy to apply once it becomes habit. You do not need willpower. You need a couple of reflexes.
- Reframe into the unit that matters. Whenever a number is presented to you, translate it into the frame you actually care about, usually the long-horizon total. “Per day” becomes per year and per decade. A percentage fee becomes a euro amount over your investing lifetime. A monthly saving becomes its multi-decade sum. The flattering frame loses its power the moment you restate it honestly.
- Interrogate every anchor. When a number is steering you, ask one question: is this number actually relevant, or is it just the first one I saw? The original sticker price, your purchase price, last year’s high: these are anchors masquerading as reference points. Strip them out and judge the thing on its own merits, here and now.
- Run the from-scratch test. Before continuing anything you have already sunk money into, ask whether you would start it today knowing what you know now. Let only the future decide the future.
What you can do
- Restate every offer in your own units. When you see “less than a coffee a day” or “only 1%,” convert it to the yearly and lifetime total before you decide. The honest frame is the one that should drive the choice.
- Name your anchors out loud. For any price or investment decision, identify the first number that is shaping your judgement and ask whether it deserves to. The market does not know what you paid; neither should your decision.
- Kill sunk costs with one question. Knowing what you know now, would you choose this fresh today? If not, stop, and stop counting the past spending as a reason.
- Frame your own goals on purpose. Framing is not only used against you. You can use it for yourself: picturing a saving habit as its thirty-year total can make it feel as significant as it truly is.
Framing and anchoring are about how outside wording and stray numbers steer a single decision. The next bias is about a different outside force, the most powerful one of all: other people. The pull to do what the crowd is doing builds bubbles on the way up and crashes on the way down. That is herd behaviour and FOMO, and it is where we go next.
