The Psychology of Your 20s – Episode 401: The Psychology of Microtrends

Host: Jemma Sbeg
Date: March 30, 2026

Episode Overview

This episode explores the psychology behind microtrends—those short-lived, quickly forgotten fashion and lifestyle trends dominating social media and online culture, particularly among people in their 20s. Host Jemma Sbeg breaks down why we’re drawn in, how microtrends manipulate our brains and emotions, and why these cycles are faster than ever before. She delves into evolutionary psychology, the dopamine feedback loop, social conformity, and ends with practical advice on how to resist the pitfalls of fast-fashion culture and find more sustainable ways to express ourselves.

Main Discussion Points & Insights

1. What Is a Trend Versus a Microtrend?

• [03:35 – 08:30]
  • Trends are sustained changes in preferences that often reflect broader cultural, technological, or societal shifts.
  • Three essentials of a trend:
    • Direction (introduces something new)
    • Duration (lasts for a meaningful period)
    • Scale (adopted widely)
  • Example: Evolution of jean styles over decades aligning with social sentiments.
  • Microtrends, in contrast, are short-lived, niche, rise and fall rapidly, and are largely driven by social media and fast fashion.

“Micro trends are short lived, they are niche, they are forgotten about very quickly and they are overwhelmingly driven by social media... Like social media trends, they inflate really fast as everyone wants to get on board and then the next thing comes along and they get dropped very quickly.”
— Jemma Sbeg [05:56]

2. The Five Stage Cycle of Trends

• [08:30 – 14:10]
  • Introduction (often via runway, celebs, or grassroots)
  • Rise (gains visibility, brands start betting)
  • Peak (mass adoption, widely available)
  • Decline (oversaturation, “cool” factor fades)
  • Obsolescence (trend is considered outdated, but may resurface in the future)

“The life cycle of any fashion trend... can be divided into five stages: introduction, rise, peak, decline and obsolescence.”
— Jemma Sbeg [09:55]

• Fast fashion and social media condense this cycle from decades to mere weeks or months.

3. How Fast Fashion Fuels Microtrends

• [14:10 – 19:35]
  • Companies like Shein and Zara can replicate viral items within 48 hours.
  • Massive daily influx of new items (Shein adds 2,000–10,000 new styles per day).
  • Business model focused on quantity and replication, not quality.
  • Social and production pipeline developments have made what’s “in” fleeting and hyper-accessible.

“Something could start trending on Monday... By Friday, Amazon, Shein, Zara could be shipping out their first prototypes of that trend because that's how fast they operate these days.”
— Jemma Sbeg [13:27]

4. The Psychological Drivers: Social Proof & Social Contagion

• [19:35 – 27:30]
  • Social Proof: We look to others to decide what’s acceptable or desirable—especially when uncertain.
  • Social Contagion: The unconscious spread of behaviors through our networks (even more potent when we feel close or want to emulate the trendsetters).
  • Influencers and celebrities make trends aspirational, exploiting our desire to be “in.”
  • The closer or more admired the source, the more infectious the trend.
  • The broader adoption means the trend is quickly adapted (or diluted) to fit many subgroups.

“Trends give us a shorthand mental and emotional code for what is going to give us acceptance... If the cool girls are wearing baggy jeans, your mind says, well, if I wear baggy jeans, I will be a cool girl.”
— Jemma Sbeg [20:48]

5. Social Conformity & Biological Reinforcement

• [27:30 – 29:21]
  • Conformity reduces uncertainty and FOMO; trends become social currency.
  • Neurologically, conforming triggers reward pathways—studies show positive reinforcement lights up when we fit in.
  • We are hardwired to want to belong, especially in our 20s, a phase of identity exploration.

“Conforming, whether it's through fashion, through music, through behavior, is a incredibly addictive and powerful form of positive reinforcement learning.”
— Jemma Sbeg [23:10]

6. Dopamine Culture & Addictive Shopping Loops

• [29:21 – 35:04]
  • Microtrends are engineered to exploit dopamine: the neurochemical released during novelty, anticipation, and acquisition.
  • Shopping becomes entertainment—scrolling, clicking, buying feeds a reward loop.
  • Brands create urgency (timers, FOMO, scarcity), confirm-shaming, and social proof ("X just bought Y!") to manipulate emotions and hasten purchases.
  • Over time, the brain needs “more” for the same hit, fueling consumption.

“Dopamine culture... the rush that we get when we browse, when we click, when we buy, when we have our purchase... Micro trends activate dopamine in so many ways, through novelty, through this anticipation cycle.”
— Jemma Sbeg [29:29]

7. Why Our 20s Are So Vulnerable to Microtrends

• [35:05 – 38:45]
  • The 20s are a time of identity formation and instability.
  • Microtrends offer quick identity scaffolding, providing belonging amid uncertainty.
  • Shopping becomes a way to cope, regulate emotion, and seek control—especially when other aspects of life feel chaotic.

“Why they are so appealing during this decade is because they provide a psychological sense of security or safety through which we can reaffirm our identity.”
— Jemma Sbeg [36:45]

• Aspirational buying keeps us hooked on the idea that “one more purchase” will complete us.

8. The Cost: Financial, Environmental, Emotional

• [38:45 – 43:07]
  • Microtrends are environmentally unsustainable and expensive (estimated $250/mo on the low end for shopping addiction).
  • The younger or less stable your identity, the higher your spend.
  • True style comes from intentional choices, not rapid cycles.
  • Increasing awareness is helping some people resist the microtrend cycle.

“Micro trends are like a bad relationship that keep you hooked on potential... They give you the hope that if I buy into this trend, I will finally feel like myself.”
— Jemma Sbeg [39:45]

9. The Shift: From Microtrend to Personal Vibe / Individuality

• [47:58 – 53:21]
  • Microtrends are dying, people are becoming more environmentally and waste conscious.
  • Article highlights: “Micro Trends are Dead, Long Live the Vibe” (Vogue), and “Are Micro Trends Over?”
  • Online fashion discourse is shifting: Individuality, authenticity, and “having a vibe” trump chasing fleeting trends.
  • Being “anti-trend” or intentionally individual is now a form of rebellion.

“Being trendy is no longer core. Being individual is. Personal expression, being anti trend. That is emerging as a counterweight to the algorithm driven micro trend online environment... Having something nobody else can replicate is the trend.”
— Jemma Sbeg [48:23]

10. Practical Advice to Resist Microtrend Pressures

[53:21 – 57:43]

• Before buying, seek the best version of the item, not the first.
• If you feel an impulsive urge to buy, pause for 24–48 hours.
• Ask yourself: Do I want the item, or the lifestyle it promises?
• Check whether a brand invests more in marketing than craftsmanship.
• Keep a running wish list and check if you still want items at month’s end.
• Reflect: What were you wearing during your happiest moment? Did it really matter?
• Value spending on memories and experiences over closet churn.

“If you can understand your identity and social psychology better than [marketers] do, you will not be manipulated by them into buying something just to feel like you need to belong.”
— Jemma Sbeg [55:23]

Notable Quotes & Memorable Moments

• “I bought a Labubu last year. I have to admit it. I currently have a pair of office siren glasses... So tiny. That is a discussion for a whole other time.”
  — Jemma Sbeg [03:25]
  (A moment of self-deprecating candor about falling for microtrends herself.)

• “It’s basically like, I think microtrends are like a bad relationship that keep you hooked on potential... They basically give you the sense that, like, just one more, one more day, one more purchase, and everything will finally be okay.”
  — Jemma Sbeg [39:45]

• “The human brain is not a thinking machine that feels. It is a feeling machine that thinks.”
  — Quoted neuroscientist Terry Wu, paraphrased by Jemma Sbeg [36:55]

• “Trends are nothing without attention... Longevity is no longer the goal.”
  — Jemma Sbeg [32:09]

• “Remember COVID? Everybody was buying toilet paper. Nobody needed that much toilet paper. This was a proxy for a sense of security and a sense of certainty.”
