Why Does Everyone Else's September Look Better Than Yours?

Because you are comparing your ordinary Tuesday with other people's edited highlights, and your mind treats both as the same kind of information. Psychologists call this upward social comparison — measuring yourself against someone you judge to be doing better — and September concentrates it, because everybody posts their fresh start in the same fortnight.

This is a description of a common pattern, not a diagnosis of anything. If you have felt flatter than usual scrolling this week, the most likely explanation is not that your life is behind. It is that you have been handed an unusually dense sample of other people's beginnings.

The idea underneath it

In 1954, Leon Festinger published A Theory of Social Comparison Processes in the journal Human Relations, proposing something that now sounds obvious: people have a drive to evaluate their own opinions and abilities, and when there is no objective measure available, they evaluate themselves against other people instead.

That last clause is the interesting one. Comparison is what the mind reaches for when there is no objective yardstick. There is no objective measure of whether your September is going well. So the mind borrows one — from whoever is nearest, and lately that means whoever is in the feed.

Why September in particular

Three things stack up in the same fortnight:

• Everyone starts at once. School years, work years, gym memberships, new terms. Beginnings are the most postable moment of any project, and they all land in the same week.

• You see the beginning, never the middle. The first-day photo gets posted. Week six does not.

• You are comparing across categories. Someone's new job, someone else's holiday, a third person's tidy kitchen — assembled into a single imaginary person who is doing better than you at everything simultaneously. That person does not exist.

How much of you is exposed to this

Pew Research Center's Americans' Social Media Use 2025, published in November 2025 and based on a survey of 5,022 US adults fielded between 5 February and 18 June 2025, found that 84% of US adults use YouTube, 71% Facebook, 50% Instagram, 37% TikTok, 32% WhatsApp and 26% Reddit.

That is exposure, not harm. The figures say most adults are in the room where comparison happens; they say nothing at all about what it does to any particular person.

What the research does and does not show

Here is where honesty matters more than a satisfying conclusion.

A 2025 study in Frontiers in Psychology examined the relationship between social media use and mental health in young adults, in two samples: 139 people aged 18–35 surveyed in October 2021, and 413 people aged 18–35 surveyed in June 2023. It found that upward comparisons mediated the relationship between social network use and lower self-esteem, and, in the second study, between social network use and depression scores.

Three qualifications the authors themselves make, which almost never survive into a headline:

1. The effects are modest. These factors explained only about 6–9% of the variance in the outcomes measured. Most of what determines how someone feels is happening elsewhere.

2. Frequent users made less extreme upward comparisons in the second study — which the authors describe as partially buffering the negative effect. That is the opposite of the simple "more scrolling, more damage" story.

3. The samples were limited — recruited online, not diverse enough to generalise, and the studies did not measure loneliness or distinguish active from passive use.

So: a real, measurable pattern, with small effects, in a specific age group, with acknowledged limitations. That is what the evidence supports. Anything stronger than that is someone selling something.

The mechanism, in one sentence

You are comparing information you have complete access to — your own doubts, your unfinished list, the morning that went badly — against information you have almost no access to, which has been selected and cropped by someone who also had a bad morning.

It is not a character flaw. It is an information asymmetry.

Four things that actually change the experience

Not "delete the apps". Things you might realistically do this week.

1. Name the comparison out loud. "I am comparing my week six to their day one." Naming it moves it from a feeling about yourself to an observation about a process, and the two are experienced very differently.

2. Ask what you would need to know. What did that person's last six months contain? What did it cost them? What did they leave out of the frame? You will not know. That is precisely the point — you are drawing a conclusion from a sample of one photograph.

3. Change what enters the feed rather than how you react to it. Reacting to a stimulus takes effort every time; removing it takes effort once. Unfollow, mute for thirty days, or move the app off the home screen. This is a design decision, not a moral one.

4. Build one non-comparative measure. Something with an objective yardstick — a page count, a walking distance, a language app's streak, an instrument. Festinger's original argument was that comparison fills the gap where objective measurement is absent. Supply the measurement and the gap gets smaller.

The uncomfortable half of the theory

Comparison is not purely corrosive. It is also how people work out what is possible, find models to learn from, and calibrate their own standards. The same mechanism that makes you feel behind in September is the one that tells you a thing can be done at all.

The useful question is not "how do I stop comparing" — you will not, and it is not clear you should want to. It is "am I comparing in a direction that teaches me anything?" Watching someone whose method you can actually see and copy is informative. Watching someone's holiday photographs is not.

Take the two-minute check

The quiz at the end of this article asks six questions about how you use your feed and how you feel afterwards, and describes which comparison pattern you are most likely running. It is a reflective exercise, not a psychological assessment, and it does not diagnose anything.

Frequently asked questions

Q: Why do I feel worse after scrolling even when nothing bad happened? A: The most common explanation is upward social comparison: you have been shown a dense sample of other people's best moments and, with no objective measure of how your own week is going, your mind has used theirs as the yardstick. The 2025 Frontiers in Psychology study found upward comparison mediating the link between social network use and lower self-esteem in young adults, though the effects were modest and other factors mattered more.

Q: Is social media bad for mental health? A: The research is more mixed and more modest than most headlines suggest. In the study cited here, the measured factors explained roughly 6–9% of the variance in outcomes, the samples were small and not diverse, and frequent users made less extreme comparisons rather than more. What is better supported is that how you use a platform — comparing versus connecting — matters more than how long you use it. Mind Decoded's position throughout is to describe what the evidence supports and stop there.

Q: What is upward social comparison? A: Comparing yourself with someone you judge to be doing better on some dimension. It comes from Leon Festinger's 1954 theory of social comparison processes, which argued that people evaluate their own abilities and opinions against others when no objective standard is available. Downward comparison — measuring against someone doing worse — is the same mechanism pointing the other way, and tends to feel better while teaching you just as little.

Q: Does taking a break from social media help? A: Some people find it does, and it is cheap to test. Rather than a permanent deletion, try muting or unfollowing the specific accounts that reliably leave you flat, for thirty days, and note how the fortnight feels. Changing the input is usually easier to sustain than trying to change your reaction to the same input every day.

Q: Why is September worse than other months for this? A: Because beginnings cluster. School terms, work years, courses and new routines all start within a fortnight, and beginnings are the most shareable stage of anything. You are seeing a compressed sample of first days, with none of the weeks that follow, which makes the average life on your screen look far more decisive than any real one.

Q: Is comparison always harmful? A: No. Comparison is how people identify what is possible and find methods worth copying. It becomes costly when the target is unreachable, the information is incomplete, and there is nothing to learn from it — a holiday photograph rather than a method. Ask whether a given comparison tells you how to do something. If it does not, it is not teaching you anything.

Q: When is this worth talking to someone about? A: If low mood, hopelessness or loss of interest lasts most of the day, most days, for a couple of weeks or more, or affects sleep, appetite or how you function, that is worth raising with your GP or another professional. This article describes a common cognitive pattern; it is not a substitute for an assessment by someone who can actually talk to you.
