Does what you wear affect how you think?

Does what you wear affect how you think?

Yes, modestly. Experiments running since 2012 have found that wearing particular clothes changes how people perform on attention and thinking tasks, and a 2023 pooled analysis of that literature put the overall effects at small to moderate. What is argued about is not whether the effect exists but how big and how reliable it is.

The term comes from a 2012 paper in the Journal of Experimental Social Psychology by Hajo Adam and Adam Galinsky, who ran three small laboratory experiments. People who put on a lab coat did better on an attention task than people who did not, and people told it was a doctor's coat sustained attention better than people told the same coat was a painter's coat. Looking at the coat was not enough; it had to be worn.

A separate group led by Michael Slepian reported five studies on formal clothing in 2015. More formal clothes went with more abstract, big-picture thinking, and in the experimental conditions produced it. The route the researchers suggested was a felt sense of power.

Did the famous lab coat study hold up?

Not as a direct repeat. A high-powered replication attempt in 2019 found no difference between the doctor coat and painter coat conditions of the original experiment. That result is reported both by the original authors in their own 2023 paper and by the British Psychological Society's Research Digest, which covered the dispute in August 2023.

Study size is part of the explanation. The Research Digest account reports that enclothed cognition studies before 2016 had about 103 participants on average, against an estimated 150 or more needed.

In 2023 the original authors, with Cristopher Horton, assessed the whole field rather than defending one paper. They pooled 105 effects from 40 studies, 3,789 participants in total. Work published before 2016 cannot rule out publication bias or false positives. Work published from 2016 onward shows no such warning sign, and its significant results are likely to hold up.

Two of that paper's three authors wrote the 2012 study it assesses, a conflict of interest the paper names. The same authors record that their 2012 paper has been cited more than 600 times and covered by more than 160 news outlets, and report the failed repeat anyway.

Is the lipstick effect real?

It depends which version you mean. As a popular economic signal it is weak: it started as a cosmetics executive's observation after the attacks of September 2001, not as research. As a laboratory finding it is real but narrow, and the best real-world spending data disagrees with the explanation the laboratory work offered.

A widely used reference encyclopedia entry, citing The Economist, carries that history: the observation came from a cosmetics company chairman after 2001, sales fell in the late-2000s recession, and The Economist's assessment is that its usefulness as an economic indicator is low.

The laboratory finding is a 2012 paper in the Journal of Personality and Social Psychology by Sarah Hill and colleagues, the first experimental demonstration of the effect. Cues about a declining economy lowered women's stated desire for most products, including electronics, and raised it for products that increase attractiveness to a mate.

Spending records complicate that explanation. An analysis published in 2020 of United States Consumer Expenditure Survey data found that cosmetics spending among women aged 18 to 40 rose during the Great Recession, regardless of whether they were married or employed, and puts the rise down to spending less on clothes rather than to mate attraction or job prospects. The two papers do not agree.

Does grooming change how you see yourself?

A little, for some people, on narrow evidence. In a 2014 experiment published in the International Journal of Cosmetic Science, men and women of ordinary body weight judged their own body size before and after applying a fragranced deodorant. Those who had been overestimating their size judged it more accurately afterwards.

People who had been underestimating their size showed no such change, which the authors treat as an individual difference rather than a general effect. The outcome measured was the accuracy of one body-size judgment, not self-esteem and not satisfaction with life, and the product was a deodorant, not a service.

That is a long way from what the selling says. In the search results gathered for this article, grooming brands claimed confidence and self-esteem benefits repeatedly and almost none pointed to a study.

Is dressing up about other people, or about you?

Both have been studied, but not equally. A 2023 review in Personality and Social Psychology Review argues that dress, meaning clothing, hairstyle, makeup and accessories, is a major driver of the first impressions other people form, and that research has given it less attention than its everyday importance suggests.

That review is about how others read you. How clothes and grooming leave the wearer feeling is the smaller literature, and it is the question that matters if you are choosing for yourself. Nothing here shows that a haircut or a facial does any of this; no study gathered looked at a salon service. Liking the result is reason enough on its own.

Where the evidence is thin

The weakest material here is the lipstick effect, which is three claims under one name: an executive's observation, a laboratory experiment, and national spending data that contradicts the experiment's explanation. Presenting them as one established finding overstates all three.

The 2019 replication paper was not read directly for this article; its result is taken from the original authors' 2023 analysis and the Research Digest account, both of which describe it. A 2017 pair of preregistered studies on formal clothing also came out mixed.

No study gathered here used an Indian sample; the participants were in the United States, the United Kingdom and other Western countries. The formal clothing work has not been through the same pooled check as the lab coat work.
