For sure, I think there is a "physiological" component here that contributes to differences in *desired* portion sizes. Though there are also societal factors in terms of bodily expectations. Paper finds that explicit gender-portion beliefs do correlate with things like support for beauty ideals.

Though also interesting that many people seem to believe in a gender effect. Check out the 500k likes on this video, for example: www.tiktok.com/@travelintho...

Yeah, I think that's right. There is certainly variance in portion sizes given at these restos -- here is a fun demonstration of that:

But that variance does not seem related to customer gender alone. Could also be as you note that men are more into order 'hacks'

This field study finding was far from obvious, though – a majority of both a laypeople and social psychologist sample predicted that men would receive larger portions than women in our field study.

Perhaps surprisingly, the field study showed no significant difference in portion sizes given to men vs. women. Hard to know exactly why this occurred, but one possibility is that standardization in serving practices at such restaurants may have limited the impact of gender on portion decisions.

But my favorite (and most expensive) part is the field study, where we sent 91 pairs of men and women – matched on BMI -- to fast-casual restaurants where they ordered the exact same meal from the same server separated by a few minutes. We then weighed their portions outside the restaurant.

Another study showed that these stereotypes impact memory. Using a “Who ordered what?” paradigm found that people remembered counter-stereotypical pairings (women with large portions, men with small portions) better than stereotype-consistent ones!

First, studies using both direct and indirect measures found that gender-portion stereotypes exist -- people consistently associate men with larger food portions and women with smaller portions, even when using the exact same foods but just showing different amounts.

Strong teak?

In basketball you can do 2009 UNC / 2010 Duke.

Yes, we do! OSF page should have RT information for each trial. osf.io/m2a9w
