Why Big Lattes Could Signal Career Success

Ever wondered why some colleagues seem to get noticed more — for promotions, projects, or praise — while others blend into the background? It might not just be their work output. According to a workplace expert citing social science, small daily habits — like your go-to coffee order — could be quietly shaping how others perceive your potential.

The short answer? Yes. People who order large coffees — such as a big latte — are often perceived as more successful and authoritative. One study found those who chose bigger food and drink portions scored 2 points higher on a 1-to-7 power and respect scale.

The Surprising Link Between Coffee Size and Career Perception

It’s a common scene: you’re in line at the café near the office, deciding between a small or large latte. But according to workplace columnist Andrew O’Connell, writing for the Harvard Business Review, that choice might matter more than you think. Research in social psychology suggests that people often associate larger portions — whether it’s a big house, a large TV, or a grande latte — with success, ambition, and status.

O’Connell highlights that making small choices to “look the part” of someone ready for advancement can influence how colleagues and managers see you. Ordering a larger coffee might unconsciously signal that you see yourself as someone destined for more responsibility.

What the Science Says About Portion Size and Perceived Power

A study conducted by researchers at HEC Paris, a leading European business school, provides some hard numbers. Participants consistently rated individuals who opted for larger food and beverage portions as having higher levels of power and respect. On a 1-to-7 scale, those who chose bigger portions averaged 2 points higher than those who did not.

While this particular research was focused on strategies to reduce obesity in lower-income populations, author Didier Dubois was examining how portion choices reflect and shape self-perception. O’Connell draws a parallel: if you want to be seen as a high performer, start acting — and ordering — like one.

How Appearance and Choices Influence Professional Trajectory

O’Connell references a well-circulated idea in management circles: “Dress for the job you want, not the job you have.” This extends beyond wardrobe. From the way you decorate your workspace to the coffee cup you carry, your daily choices can broadcast where you see yourself in the hierarchy.

The underlying principle is simple but powerful: people form opinions quickly based on subtle cues. A larger coffee might suggest confidence, ambition, or simply that you’re thinking ahead — traits often associated with leadership potential.
