I want what she's eating, thanks - what are the most popular dishes at chinese restaurant

Are you independent when you read the menu carefully? minded?
Many of us are not.
A Duke University study found that if diners know that a dish is one of the most popular restaurants, they are at least 13% more likely to order.
Fang Hanming, an economist at Duke University, one of the authors of the study, said people have too much information.
By picking the most popular dishes, diners are "learning from others who face similar choices ".
This study can be called a simple study like "How to Order.
"But this is an academic paper, so it is called" observational learning: Evidence of experiments in the field of random nature "and will be published in the US economic review, published in June. Fang’s co-
The author is Cai Hongbin and Chen Yuyu from Peking University.
The study was conducted in 2006 at the east slope restaurant in Meizhou, Beijing.
The chain has 13 locations and seats are available
Come down for dinner with about 60 menu items in the middlelevel price.
In the first week, the researchers collected data on customer food choices without intervention.
Then, in the second week, in addition to the usual menu in the restaurant, they randomly placed placards on some tables.
Half of the placards are named top-
The five most popular dishes of the previous week;
The other half lists five sample dishes that are not considered popular.
Demand for top products
Five dishes increased by 13% to 20%, the researchers said.
"By contrast, it is not significantly increasing their demand to just be mentioned some sample dishes.
So are diners learning from others, or are they just following a group of people?
"Our experimental design cannot completely distinguish between consistency and this observational learning effect," Fang said . ".
"But if consistency works ---
Who meets?
These popularity rankings are based on decisions made by people who ate in restaurants a week ago.
In our study, diners may not understand them, so any integration effect may be weak.
"The paper notes that the study was helped by Chinese habits, that is, a la carte by a host and a fee paid for it.
This allows researchers to treat each table and Bill as a single decision-making unit without having to guess which person ordered what. (
