Why You Remember Old Habits Being Harder to Break Than They Were
When seventeen-year-old Arjun from Mumbai successfully lost 15 kilograms over six months through diet changes and regular exercise, his friends and family were impressed. They asked him how difficult the transformation had been.
“It was incredibly hard,” Arjun told them confidently. “The first month was absolute torture. I remember struggling every single day, fighting constant hunger, dragging myself to the gym when my body screamed to stay home. I was exhausted and miserable for weeks. The cravings were unbearable. It took superhuman willpower to push through that initial phase. I honestly don’t know how I survived it.”
His younger sister Priya, who had watched his journey closely, looked confused. “But Arjun, I remember you saying just two months ago that the first month wasn’t as bad as you’d feared. You said you were pleasantly surprised that changing eating habits was easier than expected once you got started. You said the gym became enjoyable after the first week. You told Mom that you weren’t even that hungry because the new foods were filling.”
Arjun paused, genuinely surprised. Had he really said that? In his current memory, those early weeks had been extremely difficult—a heroic struggle requiring immense willpower and suffering. But Priya was right—he vaguely recalled being surprised that the changes weren’t as hard as he’d feared.
“Maybe I was just being optimistic when I said that,” Arjun rationalized. “But looking back now, I can see how hard it really was. The struggle was real.”
Their physical education teacher, who had guided Arjun’s fitness journey, later explained what had happened: “Arjun, you’re experiencing change bias—the tendency to remember past states or habits as being harder to overcome than they actually were once you’ve successfully changed. You put significant effort into losing weight, and now that you’ve succeeded, your memory has retroactively increased the difficulty of what you overcame. The actual early weeks were challenging but manageable—you said so yourself at the time. Now, months later, you remember them as nearly impossible torture that required superhuman willpower.”
She continued: “This happens because successful change creates psychological investment in the achievement. If the change was easy, your achievement seems smaller. If the change was incredibly difficult, your achievement seems more impressive. Your memory unconsciously exaggerates the past difficulty to make your current success feel more impressive and valuable. You’re not lying—you genuinely remember it being harder than it was. But this distorted memory serves your ego: ‘I overcame such difficulty’ feels better than ‘I made a moderate effort that worked out fine.'”
This cognitive bias—remembering past states, habits, or conditions as more difficult or severe than they actually were after successfully changing them—affects how we recall learning challenges, habit changes, personal growth, and any transformation we’ve achieved. Understanding change bias reveals why we give misleading advice about change, why we overestimate our own willpower and achievement, why we judge others for struggling with changes we’ve “heroically” overcome, and why success stories often exaggerate the difficulty of the journey.
What Is Change Bias?
Change bias is the memory distortion where, after investing effort in producing change and successfully achieving that change, people remember their past state, previous performance, or old habits as having been more difficult, more severe, or harder to overcome than they actually were at the time. The successful change creates retrospective exaggeration: if you used to procrastinate and now don’t, you remember past procrastination as worse than it was; if you quit smoking, you remember the addiction as stronger than you experienced it; if you learned a skill, you remember early incompetence as more extreme than it actually was. This makes your achievement seem more impressive by inflating the difficulty of what you overcame.
The phenomenon was identified by psychologists studying memory for past states. Research at University of Waterloo demonstrated that when people successfully made changes (improved study habits, quit bad habits, learned skills), they consistently misremembered their past state as worse than objective records showed. Someone who improved from average to good remembered being terrible. Someone who quit a moderate habit remembered it being severely addictive. Memory exaggerated past difficulty proportionally to how much effort went into change.
According to studies from University of Illinois, change bias operates because successful change creates investment in believing the achievement is significant. If past states were easily changed, the achievement feels minor. If past states were extremely difficult to change, the achievement feels major. This creates motivation to remember past difficulty as greater than it was. Additionally, current improved state becomes your baseline, making past poorer state seem worse by comparison than it felt when it was your reality.
Research from Carnegie Mellon University demonstrates that change bias is particularly strong when: (1) the change required significant effort or sacrifice (making achievement more valuable), (2) time has passed since the change (allowing memory to drift), (3) you publicly share your success story (motivating impressive narratives), and (4) your current state is much better than past state (making contrast stark). These conditions make remembering past states as terrible and change as heroic nearly automatic for successful changers.
The Parable of the Mountain Climbers and the Forgotten Ease
A teaching tale tells of two friends—Vikram and Aditya—who decided to learn rock climbing. Both were initially clumsy and fearful, struggling with basic techniques and afraid of heights. But both practiced regularly and, after six months, became competent climbers who could tackle challenging routes with confidence.
A year after they started, beginners approached them asking for advice: “We’re struggling so much. The fear is overwhelming. Our muscles are too weak. We can’t seem to improve. How did you overcome these challenges?”
Vikram responded dramatically: “The beginning was incredibly difficult—far harder than what you’re experiencing. I was paralyzed by fear every time I looked up at the wall. My arms were so weak I could barely pull myself up a single meter. I would shake uncontrollably and had to force myself not to quit every single session for the first three months. The struggle was immense. Only through extraordinary determination and suffering did I push through that horrible initial phase. You need to prepare for serious hardship.”
The beginners looked discouraged, wondering if they had the strength to overcome such extreme difficulties.
Aditya had been listening and frowned. “Vikram, are you remembering accurately? I trained alongside you. Yes, we struggled initially, but not to the degree you’re describing. You were nervous, not paralyzed. Your arms were weak, but not unusually so for beginners. You actually said at the time that climbing was more manageable than you’d feared. After the first few weeks, you were enjoying it despite the challenges.”
Vikram was defensive: “But looking back now, I can see how difficult it really was! The struggle was real!”
A wise climbing instructor who had coached both of them spoke up: “I kept training notes on all students. Let me check what I actually observed about Vikram.” She pulled out records from a year ago: “Week 2: Vikram nervous but progressing normally. Week 4: Vikram’s confidence growing steadily. Week 6: Vikram reports enjoying the challenge. Week 8: Vikram’s fear significantly reduced.”
She explained: “Vikram, you’ve unconsciously rewritten your memory. The actual early weeks were challenging but not the extreme suffering you now remember. This is change bias—after successfully achieving change, your memory exaggerates how difficult the past state was. This makes your achievement seem more impressive: ‘I overcame incredible adversity’ sounds better than ‘I practiced a moderately difficult skill and improved normally.'”
She continued: “The danger is that your exaggerated memory now discourages beginners. You’re telling them they face extreme suffering that you actually didn’t face. Your inflated memory of past difficulty makes you a poor advisor for others and makes you judge others harshly when they struggle with what you’ve ‘heroically’ overcome. You think ‘I pushed through such extreme difficulty; why can’t they?’ when actually you pushed through moderate difficulty that they’re also experiencing.”
Buddhist philosophy addresses change bias in teachings about honest self-reflection and avoiding pride in achievements. The Buddha taught that exaggerating your struggles or achievements to make yourself seem more impressive represents the delusion of conceit. Change bias is a form of this: unconsciously inflating past difficulty to make current achievement seem greater. True wisdom requires honest acknowledgment that growth often comes through moderate steady effort, not always heroic overcoming of extreme adversity.
The Bhagavad Gita discusses this through Krishna’s teaching about performing duty without attachment to fruits of action or pride in achievement. When you accomplish something, Krishna teaches detachment from need to make the achievement seem extraordinary by inflating the difficulty overcome. Change bias represents ego-attachment: needing to remember having overcome great difficulty to feel your achievement is significant. True achievement doesn’t need exaggerated difficulty to have value.
How Success Makes Past Struggles Seem Worse Than They Were
In addiction recovery and habit change success stories, change bias makes people who’ve successfully quit smoking, drinking, or other addictions remember the addiction as more severe and harder to quit than they actually experienced. Research shows that when former smokers describe their past smoking habit years after quitting, they consistently describe heavier addiction, stronger cravings, and more difficult withdrawal than they reported experiencing at the actual time of quitting. The successful change inflates the remembered difficulty.
Studies from University of Pennsylvania tracking smokers through quit attempts found significant gaps between actual reported difficulty during quitting versus remembered difficulty years later. During actual quitting, most reported moderate difficulty with manageable cravings. Years later, most remembered extreme difficulty with overwhelming cravings. Change bias had exaggerated the battle they’d won, making their achievement seem more heroic than the actual challenging-but-manageable process they’d experienced.
In academic and learning skill development, change bias makes people who’ve mastered difficult subjects remember early struggles as worse than they were. Research shows that advanced students asked to recall their early learning experience consistently describe themselves as having been more confused, more incompetent, and struggling more extremely than objective measures (early tests, assignments, teacher observations) show they actually were. The skill they’ve now achieved makes past incompetence seem worse by contrast.
Studies demonstrate that graduate students teaching introductory classes often give poor pedagogical advice because change bias makes them misremember their own learning. They remember being completely lost and struggling heroically when they were actually progressing normally, and they structure teaching assuming students need extreme hand-holding that they themselves didn’t actually need but now remember having needed.
In weight loss and fitness transformation narratives, change bias makes people who’ve successfully lost weight remember being heavier, less fit, and more unhealthy than they actually were before losing weight. Research shows that when people successfully lose significant weight, their memory of pre-weight-loss state becomes distorted: they remember being more sedentary, eating more poorly, and being heavier than objective records (photos, medical records, diaries) show they actually were.
Studies from Duke University comparing pre-weight-loss videos and records to post-weight-loss memories found systematic exaggeration. Someone who lost weight from 95kg to 75kg might remember starting at 100kg or 105kg. Someone who could initially run 2 kilometers might remember barely being able to walk. Change bias inflated the past state’s severity, making the transformation seem more dramatic and the achievement more impressive.
In relationship and personal growth narratives about overcoming past issues, change bias makes people remember past relationship problems or personal difficulties as worse than they were. Research shows that when people successfully improve relationships through therapy or effort, they misremember past conflicts as having been more severe and more frequent than couples’ actual therapy records show. The improved present makes past problems seem worse by contrast.
Studies demonstrate that couples in improved relationships often tell stories about “how terrible things were” that don’t match the actual difficulties they reported experiencing. Someone might say “we were fighting constantly and barely speaking,” when therapy notes show they were having two-three conflicts per week and communicating adequately most of the time. Change bias transforms “had regular manageable conflicts” into “relationship was nearly destroyed.”
In skill acquisition and professional development, change bias makes experts remember being worse beginners than they were. Research shows that when professional musicians, athletes, or craftspeople recall their early training, they describe themselves as more incompetent and struggling more severely than their instructors’ actual records show. Someone who was an average beginner remembers being terrible. Someone who progressed normally remembers the difficulty as extreme.
Studies from Juilliard School examining professional musicians’ memories of early training found systematic exaggeration. Musicians remembered being “awful” when instructor notes described them as “average beginners progressing normally.” They remembered practicing “constantly” through “excruciating” difficulty when records showed normal practice schedules with typical beginner challenges. Change bias made their current expertise seem to result from heroic overcoming of extreme early incompetence.
In mental health improvement and therapy success, change bias makes people who’ve improved through therapy remember past mental health states as more severe than clinical records show. Research shows that when people successfully treat depression, anxiety, or other conditions, their memory of pre-treatment severity systematically inflates. Someone who was moderately depressed remembers being severely depressed. Someone with manageable anxiety remembers being nearly non-functional.
Studies demonstrate this creates problems for assessing treatment effectiveness: patients’ retrospective reports of improvement reflect both actual improvement AND change bias inflating remembered pre-treatment severity. Someone might report “treatment reduced my depression from severe to mild” when records show actual movement from moderate to mild-moderate. The improvement is real but less dramatic than inflated memory suggests.
Remembering Change Honestly
The most important practice for countering change bias is checking objective records from before the change rather than trusting memory. If you have journals, videos, photos, medical records, or other documentation from your past state, review these before claiming how difficult past states were. Often you’ll discover you remember being worse off than you actually were. This provides honest baseline rather than inflated one serving current ego.
Before sharing success stories, acknowledge uncertainty about whether you’re accurately remembering past difficulty. Change bias makes you confidently remember extreme difficulty you didn’t experience. Qualify advice: “I found it challenging but manageable” rather than “it was incredibly difficult and required superhuman effort.” The latter likely reflects memory inflation, not reality.
Recognize that your current improved state changes how you perceive past states. What seems terrible looking backward might have felt manageable living through it. The contrast between current good state and past worse state makes past seem worse than it felt at the time. Consider: how bad did past state feel when it was your present, not just how bad it seems looking back?
Accept that successful change usually comes through moderate persistent effort, not heroic overcoming of extreme adversity. Change bias makes you remember heroic struggle because that makes achievement seem impressive. But most successful change involves consistent moderate effort producing gradual improvement—not the dramatic narrative memory creates. Accepting ordinary success requires letting go of inflated difficulty narrative.
Listen when people who observed your change journey give different accounts than your memory. Siblings, friends, coaches, or therapists who were present during your change often remember more accurately than you do. If they say “it wasn’t as hard as you remember” or “you weren’t as bad as you think you were,” consider they might be right and your memory might be inflated.
Remember Arjun who remembered his first fitness month as torture when he’d actually said at the time it was manageable, and Vikram who remembered being paralyzed by fear when records showed normal beginner nervousness. Both illustrate how change bias inflates past difficulty after successful change.
Change bias can’t be eliminated because we lack perfect memory and because successful change genuinely creates psychological investment in feeling the achievement is significant. But recognizing the bias allows humility: when you remember having overcome extreme difficulty, acknowledge your memory probably exaggerates. Your actual experience was likely challenging but manageable—more ordinary struggle than heroic battle. This honesty makes you give better advice to others facing similar changes and prevents judgmental “I overcame worse, so should you” attitudes when others struggle with changes you’ve inflated in memory. Most successful change comes through normal human effort overcoming normal human challenges, not the dramatic heroic narratives our biased memories create after the fact.
Frequently Asked Questions
If I genuinely did struggle severely and change was extremely difficult, is it still change bias?
Not if it’s accurate. Change bias is systematically remembering difficulty as GREATER than it actually was, not simply remembering genuine difficulty. The question is: does your current memory match what you reported experiencing at the time, or has memory inflated the difficulty? Check objective records if available—these often show less severe past states than current memory suggests.
Why would my brain make me misremember being worse off than I was?
Change bias serves psychological needs: making your achievement seem more impressive by inflating what you overcame. “I overcame extreme adversity” feels better than “I made moderate effort.” Also, your improved current state becomes your baseline, making past worse state seem more severe by contrast than it felt when it was your reality. Memory serves current psychological needs more than historical accuracy.
Does this mean I should doubt all my memories of past struggles?
Not doubt that struggles existed, but be skeptical about their remembered severity, especially after successful change. If you’ve improved significantly in something, your memory of how bad it was before is likely inflated. This doesn’t invalidate your achievement—it just means the achievement came from overcoming realistic difficulty, not the heroic extreme difficulty memory now suggests.
How can I give advice about change without change bias distorting my perspective?
Check objective records if available, listen to how you described difficulty at the actual time (not how you remember it now), and qualify advice with uncertainty: “This is how I remember it, but memory might exaggerate” rather than confidently describing extreme difficulty. Also remember: if your memory is “it was incredibly hard,” probably the reality was “it was challenging but manageable”—adjust advice accordingly.
If change bias makes past seem worse, does that mean my current achievement is less impressive?
Your achievement is real and valuable, but it probably came through more ordinary means than heroic memory suggests. Most successful change involves persistent moderate effort, not superhuman willpower overcoming extreme adversity. Accepting that your achievement is “normal successful change through normal human effort” doesn’t diminish it—it just makes it realistic rather than inflated.
