The 90% Fat-Free Cold Cuts Problem:

Walk into any grocery store and you’ll find two packages of identical cold cuts sitting side by side. One says "90% fat-free." The other says "10% fat."

They are, of course, the same thing.

Consumers reach for the first one almost every time. Daniel Kahneman uses that example in Thinking, Fast and Slow to illustrate one of the most consequential biases in finance: framing. "Different ways of presenting the same information," he writes, "often evoke different emotions."

Here’s why that matters for your retirement.

A portfolio that’s "down 20% this year" and a portfolio that’s "trading at 2022 levels" describe identical situations. But one triggers panic and the other triggers a shrug. Your investment decisions — whether to sell, hold, or buy more — depend less on the underlying reality than on which version your brain heard first.

Behavioral economist Shlomo Benartzi has written in the Wall Street Journal about a related trap: narrow framing¹. When investors evaluate individual holdings in isolation — "this stock is killing me," "this fund had a great year" — instead of evaluating the portfolio as a whole, they end up chasing winners, fleeing losers, and undermining the plan that was supposed to get them to retirement.

1. The price you paid. "I paid $11 for this stock. I’m not selling until it gets back to $11." That’s framing — anchoring on a number that has zero bearing on whether the stock still belongs in your portfolio.

2. The headline you read. "Market plunges 800 points!" sounds catastrophic. "Market down 1.6% on a Tuesday" sounds routine. Same event. Different frame. Different decision.

3. The benchmark you compare yourself to. Comparing your retirement portfolio to the S&P 500 — or to your neighbor’s "killer" investment — is what the research calls tracking error regret. Here’s another phrase for it: "the shoulda, woulda, coulda game." The frame is wrong because the goals are different.

The trouble with trying to outsmart framing is that, by definition, you don’t see the frame — you see through it. Which is why the most reliable defense isn’t a clever cognitive trick. It’s a written, goals-based investment plan that gives you a fixed reference point when the market tries to give you a moving one.

It’s also why an objective advisor matters more than most people realize. Their job isn’t to predict the market. Their job is to keep you from being managed by the market’s mood swings.
