You can’t trust your memory.
Memory is fluid. Every time you recall something you’re essentially rewriting it in your head.
Yet you’re prone to stubbornly trusting this copy of a copy of a copy — even if it no longer resembles the original:
Robert Burton describes an experiment in his book On Being Certain: Believing You Are Right Even When You Are Not, which everyone with a strong opinion should read. Immediately after the Challenger explosion in 1986, the psychologist Ulric Neisser asked 106 students to describe in writing where they were when they heard, who they were with, how they felt, what their first thoughts were. Two-and-a-half years later, the same students were assembled and asked to answer the same question in writing. The new descriptions were compared with the originals. They didn’t match. People had changed facts about where they were, who they were with, what they felt, what they thought. When confronted with the original essays, people were so attached to their new memories they had trouble believing their old ones. In fact, most refused to revise their memories to match the originals written at the time. What struck Burton was the response of one student: “That’s my handwriting, but that’s not what happened.”
Eyewitness testimony? Often worthless:
Between 1989 and 2007, for instance, 201 prisoners in the United States were freed through the use of DNA evidence. Of these, 77 percent had been mistakenly identified by eyewitnesses.
But memory isn’t just something to use when taking tests in school. It’s tightly coupled with happiness:
What does one of the foremost experts on happiness say is the biggest cause of unhappiness? My main takeaway from Harvard professor Daniel Gilbert’s bestselling book Stumbling on Happiness was:
Much of our unhappiness springs from the fact that we’re terrible at accurately remembering how things made us feel in the past, so we make bad choices regarding the future.
Ever eat too much, drink too much, or stay up too late, say “I shouldn’t do this because it makes me feel terrible”… and then do it again?
Ever dread Mondays, going to the gym or get-togethers… and then realize they’re really not that bad?
We overestimate how happy we will be on our birthdays, we underestimate how happy we will be on Monday mornings, and we make these mundane but erroneous predictions again and again, despite their regular disconfirmation.
So what are the solutions here?
Stop trusting your memory. Write things down. Feelings are fleeting. Keep a list of things that make you very happy and very sad.
Gilbert also has a suggestion that is quick and easy: Look at other people, what they do, and how they react in the moment:
This trio of studies suggests that when people are deprived of the information that imagination requires and are thus forced to use others as surrogates, they make remarkably accurate predictions about their future feelings, which suggests that the best way to predict our feelings tomorrow is to see how others are feeling today.
Sorry, you’re not a unique snowflake. We’re more similar to others than we are different. Don’t fight this, embrace it. It can be the key to a much happier life:
The irony, of course, is that surrogation is a cheap and effective way to predict one’s future emotions, but because we don’t realize just how similar we all are, we reject this reliable method and rely instead on our imaginations, as flawed and fallible as they may be.
Yes, your brain is imperfect, but it’s often imperfect in the same ways. You can use it’s errors to your advantage.
Daniel Kahneman, Nobel Prize winner and author of Thinking, Fast and Slow, has shown that your brain consistently remembers only two things about an event:
Nobel Prize-winning psychologist Daniel Kahneman and his colleagues have shown that what we remember about the pleasurable quality of our past experiences is almost entirely determined by two things: how the experiences felt when they were at their peak (best or worst), and how they felt when they ended. This “peak-end” rule of Kahneman’s is what we use to summarize the experience, and then we rely on that summary later to remind ourselves of how the experience felt.
So how can you game the system with this information and have happier memories?
Structure events so that the peak is great and the ending is great.
Make sure tomorrow has one thing that will be amazing and that the day ends on a positive note. This is what leads to feeling good about your life in retrospect.
Your brain is not a perfect computer. What you will remember is not the same as what happened.
But you can game it so your memories are better than what happened. And happy memories are one of the secrets to feeling good about your life.
