Ask someone in their 70s whether they have regrets and notice what they don’t say. They rarely lead with the bad investment, the argument that went too far, the job they should never have taken. What surfaces instead is quieter: the degree never finished, the friend never called back, the years a piano sat in the living room untouched. The mistakes seem to have made their peace. The things that never happened haven’t.
People on both sides of these conversations often sense the same asymmetry. Adult children hear a parent circle back — sometimes for decades — to a door that was never opened, and wonder why that one, of all things, is the regret that stayed.
We should say plainly who we are before going further. We are writers and parents, not clinicians or psychologists. What follows is a careful reading of published research, not therapeutic advice, and nothing here is meant to diagnose anyone’s inner life or tell anyone how to feel about their own past.
What the research actually found
In 1995, psychologists Thomas Gilovich and Victoria Husted Medvec of Cornell University published a review of their research on regret in the journal Psychological Review. Their central finding was about time. Actions — things people did and wish they hadn’t — tend to generate more regret in the short term. Inactions — things people didn’t do and wish they had — tend to produce more regret in the long run.
The pattern showed up repeatedly. When they surveyed 60 adults by telephone, 75 percent said they regretted the things they didn’t do more than the things they did. When they collected 213 specific life regrets from 77 people — students, professors emeriti, nursing home residents, clerical and custodial staff — regrets about inaction outnumbered regrets about action by roughly two to one.
This was the opposite of what earlier laboratory work had suggested. In a well-known scenario study by Daniel Kahneman and Amos Tversky, discussed in the review, one investor loses money by switching stocks and another loses the same amount by deciding not to switch; 92 percent of people said the man who acted would feel worse. In the moment, doing the wrong thing stings more than failing to do the right one.
The time element was the part that reconciled the two. When people were asked about the past week, they split almost evenly between regretting actions and inactions. When asked about their whole lives, 84 percent pointed to what they had failed to do. And in survey data from Lewis Terman’s famous longitudinal study — respondents mostly in their 70s — regrets of inaction outnumbered regrets of action by more than four to one.
The content of those regrets is recognizable. The most common involved missed educational opportunities, failures to “seize the moment,” and not giving enough time to family and friends. One detail stayed with us: not a single person in the researchers’ sample regretted time spent developing a skill or a hobby — even ones long since abandoned — while the matching list of regrets for interests never pursued ran on and on.
Why mistakes quiet down
Gilovich and Medvec proposed that several ordinary psychological processes work on our mistakes over time, like water smoothing a stone.
We repair what we did. A bad marriage can end; a wrong career can be changed. In their data, 65 percent of people said they had done more to fix their most regrettable action than their most regrettable inaction. The inaction usually just sits there.
We also find silver linings. When people in one of their studies compared their biggest regretted action with their biggest regretted inaction, three quarters said the more significant silver lining belonged to the action — the children from the wrong marriage, the lesson from the failed venture. “But I learned so much” attaches easily to things we did. It barely makes sense for things we never tried.
Why the untaken chances get louder
The reverse processes work on inactions. The fear that stopped us tends to fade from memory faster than the wish that wanted us to act, so the old reasons stop seeming like reasons. The further people get from a moment, the researchers found, the more confident they become that they could have managed it — which makes the inaction feel inexplicable in hindsight.
There is also no boundary on what might have been. A mistake’s consequences are fixed: this happened, and it was bad. A missed chance’s consequences are imagined, and imagination is generous. The picture of the life not lived can keep growing for decades, because nothing real ever arrives to correct it.
And unfinished things simply stay in the mind. In one of their studies, people recalled far more of their regretted inactions than their regretted actions three weeks after listing them. A mistake is a closed story. A thing never done remains, in some sense, still open — which is why it can still visit.
This is one body of research, not settled consensus
A few honest caveats. These studies are from the early 1990s, with mostly small American samples, and the authors themselves flagged that the pattern may be shaped by culture: a society that prizes self-fulfillment may simply generate more regret about unfulfilled selves. They noted that in cultures organized more around duty to others, regrets of action might weigh heavier and last longer.
The pattern has also been retested, with mixed texture. In 2023, Jerry Richardson and Gilovich published a replication in Royal Society Open Science using an unusual sample: 2,600 visitors to a Chicago psychology museum who hung their answers on a wall. The overall temporal pattern held — regretted actions weighed more in the short term, and regretted inactions gained ground with time — but the headline asymmetry softened. Looking back on their lives, the museum’s visitors split almost evenly between actions and inactions, nothing like the 84 percent in the original sample. The authors’ best guess is age: a family-friendly museum skews young, and the long term is not yet long when you are young. The careful reading is that the direction of the pattern looks solid; its size, especially earlier in life, is not settled.
The authors were also careful about the obvious moral. They explicitly declined to conclude that everyone should simply act boldly and “seize the moment,” noting that caution exists for good reasons and that the immediate pain of a bad decision is no less real than the long ache of a safe one. The research describes how regret tends to behave, not how anyone should live.
And regret is not one feeling. The paper discusses a distinction proposed by Daniel Kahneman between the hot, immediate kind and the wistful, long-term kind — though the authors also found that many lifelong regrets of inaction are anything but wistful.
What this can and cannot do
What this research can do is offer a frame. If a parent keeps returning to something they never did, it may help to know this is one of the most ordinary patterns in the psychology of memory — not a sign of a sad life, and not something a listener is expected to fix. It can also soften self-judgment: the regret that grew louder over forty years did not grow because the failure was enormous. It grew because that is what unfinished things tend to do in human memory.
What it cannot do is resolve anything. Reading about regret does not retire one, and an article is not an intervention. Where regret shades into rumination, depression, or real strain between family members, the right move is a conversation with a family therapist or counselor, who can do what no piece of writing can.
Perhaps the kindest reading is this: the regrets that stay are not proof of a life badly lived. They are proof that somewhere in us, the door we never opened was never fully closed — and memory, in its clumsy way, keeps checking on it.
