Ask people how much they have changed over the past ten years and most will tell you: quite a lot. Their tastes, values, friendships and goals look different than they did a decade ago. Then ask how much they expect to change over the next ten years, and the answer shifts. Not that much, they say. They feel they have mostly become who they are going to be.
Psychologists call this pattern the end-of-history illusion. Research published in the early 2010s, drawing on large numbers of adults across a wide range of ages, found that people at every stage of life tended to underestimate how much they would change in the future, even while recognizing how much they had changed in the past.
Why we fall for it
Part of the explanation is simple. Remembering who you used to be is relatively easy, because you have the evidence. Imagining who you will become is hard, because you don’t yet know what experiences, people and setbacks are coming. When we can’t picture a change, we tend to assume it won’t happen.
There is also comfort in feeling finished. If your current self is the final version, the world feels more predictable. But that comfort comes at a cost when it shapes big decisions.
What it means for a new chapter
Graduation season is full of pressure to have life figured out. Graduates are asked to choose careers, cities and paths as if the person they are at twenty-two will be the same person at forty. The end-of-history illusion suggests that is unlikely. Your interests will shift. Your priorities will mature. Things you can’t imagine caring about now may become central.
That is not a reason to avoid commitment. It is a reason to hold your plans with an open hand and to choose paths that leave room for growth.
What it means after a setback
The illusion has a darker side, too. In the middle of a hard season, it is easy to believe that the way you feel now is the way you will always feel. Discouraged people often assume their discouragement is permanent. Someone who failed at something may assume they will always be the kind of person who fails at it.
The research points the other way. You are very likely to keep changing. The person getting through a difficult year is not the final draft, and the version of you five years from now may handle today’s problems with a skill and perspective you can’t yet picture.
Using it well
- Make reversible choices when you can. Favor options that can be adjusted as you learn more about yourself.
- Be generous with your future self. Avoid decisions that lock that person into today’s preferences or today’s pain.
- Look back to see forward. List the ways you have changed over the last decade, and assume the next decade will bring at least as much.
- Stay curious about who you’re becoming. Treat your growth as something to discover rather than something already settled.
The feeling that you are finished changing seems true at every age. It almost never is, and that is very good news.
