Why Familiar Financial Choices Feel Safer Than They Really Are

A behavioural finance perspective on longevity bias—and why an investment, company or financial product should not be trusted merely because it has existed for a long time.

Imagine being offered a piece of chocolate from a brand that has existed for more than 70 years.

You take a bite. It tastes smooth, rich and surprisingly good.

Now imagine tasting chocolate from a new brand that has been on the market for only three years. This time, you find it less appealing—perhaps slightly waxy and not quite sweet enough.

Here is the surprising part: both pieces of chocolate are identical.

In an experiment described in the book Gap Selling, participants gave higher ratings to chocolate when they believed it came from an established brand. Those who thought the same chocolate came from a newer brand rated it less favourably.

The product had not changed.

Only its supposed history had changed.

Most participants did not consciously identify the age of the brand as an important factor. Yet the suggestion of longevity still influenced what they experienced.

The same thing happens when we make financial decisions.

Most people assume that something which has existed for a long time must be safer or better.

A company that has operated for several decades appears dependable.

A stock with a long history of good performance feels like a reliable investment.

A financial institution that our family has used for generations seems more trustworthy.

An insurance policy that we have held for many years feels too valuable—or too risky—to reconsider.

There is some truth behind this thinking. Longevity can provide useful evidence.

A business that has survived recessions, technological disruption and changing consumer preferences may possess genuine resilience. A long-established financial institution may have stronger systems and more experience than a new entrant. An older insurance policy may contain benefits that are no longer available today.

However, longevity is only one piece of evidence.

It is not a guarantee of quality, suitability or future success.

The tendency to judge something more favourably because it has existed for a long time is known as longevity bias.

Our minds often associate age with legitimacy:

“It must be good. Otherwise, it would not have lasted this long.”

This mental shortcut saves us time. Instead of examining every detail, we use longevity as a signal of trustworthiness.

The danger begins when the signal replaces the analysis.

Longevity bias can interact with several other behavioural tendencies.

Familiarity bias

We naturally feel more comfortable with companies, products and institutions we recognise. Familiarity reduces emotional uncertainty, but it does not necessarily reduce financial risk.

Status quo bias

Changing an existing arrangement requires effort and creates uncertainty. Keeping things as they are feels easier—even when better alternatives may exist.

Endowment effect

Once we own something, we tend to value it more highly. The longer we have owned it, the more difficult it may become to assess objectively.

Sunk-cost thinking

We may continue with an investment or financial product because of the time and money already committed, even though those past costs should not determine the best decision today.

Together, these biases can turn a familiar financial choice into an emotional attachment.

We stop asking whether it still deserves a place in our portfolio or financial plan. We retain it because it has always been there.

Through investing and financial planning conversations, I have observed that people rarely describe their decisions as emotional.

They usually provide logical-sounding explanations:

• “This company has been around for decades.”
• “My parents have always used this bank.”
• “I have held this investment for many years.”
• “Nothing has gone wrong with this policy so far.”
• “This has always been a reliable brand.”

These statements may be factually correct. But they do not fully answer the most important question:

Is this still the best decision based on the evidence today?

Time can create emotional legitimacy.

The longer something has been part of our lives, the more natural it feels. The more natural it feels, the safer it appears. We may then interpret that feeling of safety as proof that the decision remains sound.

But emotional comfort and financial suitability are not the same thing.

A familiar investment can still be overvalued.

A long-established company can still lose its competitive advantage.

An old financial product can still become unsuitable as our circumstances change.

Conversely, a newer alternative is not automatically better simply because it is more innovative.

The objective is not to favour the old or the new. It is to evaluate both fairly.

That is the core of The Value Steward perspective: respect history, but do not let history make the decision for you.

To separate genuine value from the comfort of familiarity, consider using the MARGIN framework.

1. M — Measure current value

Ask what the investment, company or financial product provides today.

Historical performance and past reputation may explain why you chose it originally. They do not automatically justify continuing with it.

For an investment, examine its present valuation, financial strength and future prospects.

For a financial product, examine its current benefits, costs, limitations and purpose within your broader plan.

2. A — Assess present suitability

A good decision made ten years ago may not remain suitable today.

Your income, dependants, liabilities, health, risk tolerance and financial goals may have changed. The product itself—or the economic environment surrounding it—may also have changed.

Do not ask only whether the original decision was sensible.

Ask whether it still meets your needs now.

3. R — Review realistic alternatives

Existing arrangements often win by default because people compare them with nothing.

Instead, compare your current choice with reasonable alternatives. Consider their benefits, risks, costs and trade-offs.

The objective is not to chase whatever is newest. It is to understand the opportunity cost of remaining where you are.

4. G — Guard against familiarity

Ask yourself:

“If I did not already own this, would I choose it today?”

This is one of the most useful questions for overcoming longevity bias, the endowment effect and status quo bias.

It helps separate the quality of the decision from the emotional comfort created by ownership and history.

5. I — Investigate the evidence

Look beyond age, reputation and reassuring stories.

For a company, consider:

• Does it still possess a durable competitive advantage?
• Is its balance sheet healthy?
• Can it adapt to technological or regulatory changes?
• Are its future prospects already reflected in the share price?

For a financial product, consider:

• What purpose does it serve?
• Does it still meet that purpose?
• What are its costs and limitations?
• What might be lost if it is changed or replaced?

Longevity should prompt investigation, not end it.

6. N — Never change merely for novelty

Avoiding longevity bias does not mean automatically choosing the newest option.

New products and companies can introduce different risks. They may have short track records, untested business models or features that have not yet been tested under difficult conditions.

A careful decision-maker should neither worship tradition nor chase novelty.

The goal is to favour the option best supported by evidence—with an adequate margin of safety if your assumptions turn out to be wrong.

Imagine an investor who has owned shares in a famous company for 15 years.

The investment performed exceptionally well. The company survived recessions and market crashes, and its brand became recognised around the world.

Over time, the investor’s relationship with the shares changed.

They were no longer merely an investment. They became part of his story.

The profits may have helped him pay for his first home or support his family. Holding the company through several market downturns may have reinforced his identity as a patient, long-term investor.

But the business has since changed.

Its competitive advantage is weakening. Growth is slowing. Debt is rising, and its valuation assumes an optimistic future.

The investor continues holding—not necessarily because the evidence remains compelling, but because selling feels like abandoning 15 years of history.

A value investor must separate two different questions:

1. Is this still a good company?
2. Is it still a good investment at today’s price?

A wonderful company can become a poor investment if its price is too high. Likewise, a company’s historical success does not guarantee that it will successfully navigate the next stage of its industry.

The same principle applies to financial planning.

An older insurance policy may still be valuable, particularly if it contains favourable terms or benefits that are no longer available. Replacing it without proper analysis could result in lost benefits, new exclusions, fresh underwriting or higher costs.

But keeping it merely because it is old is not analysis either.

The right approach is to review before replacing—but also to review before automatically retaining.

Choose one long-held investment, insurance policy, banking relationship or financial habit and conduct a simple longevity-bias review.

Ask yourself the following questions:

1. What was its original purpose?

Be specific.

Was the investment intended to provide growth, income or diversification? Was the insurance policy meant to protect a particular liability or dependant? Was the account chosen for convenience, interest or access to certain services?

2. Does it still fulfil that purpose?

Your needs may have changed even if the product has not.

A decision that once fitted your circumstances may now be insufficient, excessive or irrelevant.

3. What has changed since I chose it?

Consider changes in:

• Your financial position
• Your family responsibilities
• The company or product
• Fees and features
• Available alternatives
• Market conditions
• Laws and regulations
• Your ability and willingness to accept risk

4. Would I choose it today?

Imagine that you do not already own it.

Would you still buy it based on its current value, benefits and risks? Or does it only seem attractive because it is already familiar?

5. What could I lose by changing it?

Do not make changes without understanding the consequences.

Selling an investment may have transaction, tax or portfolio implications. Replacing an insurance policy may result in lost benefits, new underwriting requirements or a period without adequate protection.

6. What could I lose by doing nothing?

Inaction also has a cost.

You may remain exposed to an outdated investment thesis, inadequate protection, unnecessary fees or missed opportunities.

The proper comparison is not between change and no risk. It is between the risks and benefits of changing and those of remaining where you are.

Longevity is a signal, not a verdict. Something that has survived for a long time may deserve respect, but it should not receive permanent immunity from review. Wise stewardship means appreciating the past while ensuring that every investment, financial product and habit continues to earn its place in your life today.

What financial decision are you retaining because it remains genuinely suitable—and what might you be keeping simply because it feels familiar?
