The Psychology of Misjudgment Behind Anchoring to Your Account's Original Rate

Charlie Munger's published work on the psychology of human misjudgment, translated into a household test for anchoring bias: judging your current savings rate against the rate you remember opening the account at, instead of today's market.

Compare to Today's Market, Not Your Memory

Charlie Munger's published work on the psychology of human misjudgment repeatedly examined how an initial reference point distorts later judgment, and the psychology of misjudgment behind anchoring to your account's original rate describes exactly this pattern: a saver continues judging their rate as reasonable relative to what it was when they opened the account, rather than relative to today's actual market. For example, consider a saver who opened an account at 2.1% APY several years ago, considered an excellent rate at the time, and has continued to feel satisfied with the account even as its rate crept to 3.9% APY, still comparing it favorably against the 2.1% anchor rather than against today's best available 4.3% APY. On a $17,000 balance, that anchored comparison masks a real $68 annual gap against the current best option, small on its own but a symptom of a comparison habit anchored to the wrong reference point. Per the USC archive of Munger's psychology speech, Munger's published work consistently examined how an initial reference point continues to distort judgment long after it's stopped being relevant. As of July 2026, this is especially important if you find yourself judging your current rate as "pretty good" relative to what you remember it being when you opened the account.

The rate improved from the opening anchor, but still trails today's actual best option.

Replace the Old Anchor With Today's Number

Per Poor Charlie's Almanack, recognizing when an initial reference point continues to distort judgment was treated as one of the most valuable corrections to build into a decision habit. Comparing your rate against the national average of 0.38% APY and the best available 4.20% APY, using FDIC national rate data, replaces the memory-based anchor with the actual current benchmark.

Replacing the old anchor with today's actual market data has real benefits: it reveals a genuine, current gap that a memory-based comparison can mask indefinitely. The risk of anchoring to an old opening rate, as the $68 gap example shows, is a real, ongoing cost that persists precisely because the comparison habit itself is distorted. However, that said, it depends on how long ago the account was opened compared to how much rates have moved since: an account opened recently has less anchoring distortion than one opened years ago during a very different rate environment. If you're deciding how to judge your current rate, choose to compare against today's national data if it's been more than a year since you last checked against a current benchmark; choose to trust your existing sense of the account only if you've recently confirmed it against today's actual market. This is when this matters most: any time you catch yourself judging a rate as "pretty good" based on a memory rather than a current comparison.

01
Identify the anchor

The rate you remember from opening the account, not today's market.

02
Replace it with current data

Today's national average and best available rate, checked directly.

03
Watch for 'pretty good' judgments

That phrase often signals an anchored, not current, comparison.

04
Recheck periodically

The gap between an old anchor and today's market grows over time.

When This May Not Apply

An account opened recently, when rates were similar to today's, has less anchoring distortion, and the memory-based comparison is closer to accurate. This is especially important to distinguish from an account opened years ago during a meaningfully different rate environment.

What to Do Next, in 20 Minutes

  1. Notice if you're judging your rate against a remembered opening rate.
  2. Compare it instead against current savings rates and the national average.
  3. Read patience versus inertia in investment and savings accounts and the stay the course test for switching fatigue for related frameworks.
  4. Read the quiet theft of low yields for the fuller cost of an uncorrected rate gap.
  5. Run a full Money Map check to see where your account stands today.

Frequently asked questions

What is anchoring bias in the context of a savings rate?+
Anchoring bias means judging your current rate as good or acceptable relative to the rate you remember when you opened the account, rather than relative to what's actually available in today's market, which may have moved substantially since then.
Why does this matter more during a period of changing rates?+
If rates were low when you opened an account and have since risen, or vice versa, your memory-based anchor becomes increasingly disconnected from the current market, making the account feel fine when it's actually fallen behind, or feel poor when it's actually competitive.
How do I correct for this bias?+
Compare your current rate against today's published national average and best available rate directly, rather than against your memory of the account's original rate, every time you evaluate whether to keep or switch.
