At seventy, I'm less sure about things than I was at forty. I didn't expect my views to change as much as they have. I once assumed, without giving it much thought, that the way I understood the world would remain broadly the same.
It hasn't.
I'm not claiming that everything I once believed was wrong. Rather, I've become more aware of how complicated things can be, how much I don't know, and how easily we mistake our present understanding for the whole truth.
That may be one of the most valuable things a lifetime can teach us. Yet it's an experience we rarely make enough use of, especially when it comes to helping younger people navigate their own lives.
The Experience We Leave Untapped
Every older person has lived through things that younger people haven't. Some have made painful mistakes. Others have made good decisions for reasons they only understood much later. Many have discovered that what seemed important at twenty or forty looks different decades afterward.
That experience doesn't automatically make someone wise. People can spend a lifetime repeating the same mistakes, defending old prejudices or refusing to reconsider what they believe.
But some people do reflect honestly on their lives. They recognize where they were wrong, what they misunderstood and what they wish they had known earlier.
Their experiences could be enormously useful to younger people—not as instructions to follow blindly, but as evidence to consider before making their own decisions.
The question is how to pass that experience on without turning it into a lecture.
The World Has Changed—and Older People Need to Admit It
One reason younger people may dismiss advice from older generations is that some of it no longer fits the world they live in.
Consider housing. Someone who bought a home decades ago might advise a young person to work hard, save a deposit and buy as soon as possible. That advice may have made sense in the circumstances of their own life.
But today's young adults may face house prices and rents that have risen far faster than their incomes, along with student debt, insecure employment and other financial pressures. The same path may be much harder to follow.
Telling someone to repeat a strategy that worked under different economic conditions isn't wisdom. It overlooks the reality they face.
Yet the experience behind the advice may still be valuable. An older person might explain the trade-offs they considered, the risks they took, the mistakes they made or the sacrifices they found worthwhile. That can help a younger person think more clearly about their own circumstances.
For example, buying a home at almost any cost may create the appearance of financial security while leaving someone struggling with repayments and unable to cope with an emergency. Understanding the risks, keeping some financial flexibility and resisting the pressure to measure success by property ownership may be more useful lessons than simply being told to buy.
Older people don't have all the answers. But when they acknowledge how much the world has changed, their experience can help younger people ask better questions and avoid costly mistakes.
Why Our Advice Often Goes Unheard
Advice can fail even when it's sensible.
Nobody particularly enjoys being told how to live, especially by someone who seems to assume they understand the problems better than the person experiencing them. Advice can sound like criticism, a dismissal of someone's difficulties or a claim that the older person's life choices were superior.
Younger people also have reasons to question the wisdom of previous generations. They can see mistakes made by their parents and grandparents, including social attitudes that were once widely accepted but are now recognized as unfair or harmful.
And they are right to question them.
Experience can teach us a great deal, but it can also reinforce our mistakes; surviving a difficult situation doesn't necessarily mean we handled it in the best possible way.
Perhaps the most useful thing older people can do is explain what actually happened: what they believed at the time, what they got wrong, what they learned and what remains uncertain. A genuine story invites reflection. A lecture tends to invite resistance.
What Research Tells Us About Wisdom
There is research on whether wisdom increases with age, and the findings offer a useful caution against romanticizing experience.
A 2023 meta-analysis by Mengxi Dong, Nic M. Weststrate and Marc A. Fournier examined three decades of psychological research on wisdom. Across the measures studied, the overall correlation between age and wisdom was just r = .04—statistically significant, but practically trivial. Most measures of wisdom showed no statistically significant relationship with age.
In other words, getting older does not, by itself, make someone wiser.
Research by psychologists Igor Grossmann and Ethan Kross offers a related insight. Their 2014 study of what they called Solomon's Paradox found that people tended to reason more wisely about another person's problems than about their own. Encouraging people to step back psychologically from a problem helped reduce that difference, with comparable effects among younger and older adults.
The implication is important: wisdom depends not simply on how long we have lived, but on how we reflect, consider other perspectives and recognize the limits of our own knowledge.
This strengthens the case for sharing life experience, but it also sets a condition. The value lies not in age alone, but in the willingness to examine experience honestly and learn from it. People who have reflected carefully on their lives may have something useful to offer, whatever their age.
One practical example is Cornell gerontologist Karl Pillemer's Legacy Project, which collected life lessons from more than 1,500 older Americans. The project explored subjects including relationships, work, raising children, happiness and avoiding regret. Its value lies in preserving what people say they learned through experience—not in proving that every older person's advice is correct.
What Will We Leave Behind?
We spend considerable time and money passing on material possessions, but we rarely think as carefully about passing on the lessons of a life.
Some of those lessons may be practical: how to handle money, choose a partner, cope with loss or avoid a decision that brings years of regret. Others may be less tangible: learning to tolerate uncertainty, changing your mind when the evidence changes, or recognizing that being certain is not the same as being right.
The Legacy Project is one example of how these experiences can be gathered and shared. But the same thing can happen in ordinary conversations between generations, if people are willing to listen and speak honestly.
I can offer younger people something that might help them along the way: an honest account of what I've experienced, what I've learned and what I still don't know.
Perhaps the most valuable legacy of a lifetime isn't a set of answers. It's the willingness to keep questioning, the humility to admit what we don't know, and the experiences we share to help the next generation find its own way.
The Watchdog Takeaway
Experience is a resource, not a guarantee of wisdom. The most useful lessons older people can offer come from honest reflection—including the mistakes they made, the beliefs they changed and the things they still don't know. Younger people don't need to accept those lessons uncritically. They deserve the opportunity to consider them and decide what applies to their own lives.
Evidence: Interpretive
The research supports the distinction between age and wisdom, but the broader argument—that sharing life experience can help younger people make better decisions—is an interpretation, not a conclusion directly established by these studies.
