CAPTCHAs point out that respondents do not prove to be 'human', but only to prove that they are 'American'



CAPTCHAs and reCAPTCHAs that you encounter when visiting websites or registering as users raise problems such as 'Please select all XX tiles' and the user identifies whether the bot is human. British hacker Terence Eden accused CAPTCHA of 'not proving that he is a human being, but proving that he is an'American'', and many people agree. I am sending comments.

CAPTCHAs don't prove you're human – they prove you're American – Terence Eden's Blog

When you are requested to authenticate with a CAPTCHA or reCAPTCHA, the following screen will be displayed. If you check 'I'm not a robot' ...



As shown in the screen below, a quiz such as 'Please select all the images of the pedestrian crossing. When you have selected all, click [Confirm]' will be given.



There are various quizzes to be asked, such as 'Please select all the tiles on the bus' ...



You may also select 'Mountains and hills'.



Also, in the case of a quiz such as 'Please select all the tiles of the traffic light', many people have been very worried about whether to include the part that slightly protrudes from the next tile in the 'traffic light'.



In a blog post about CAPTCHAs, Eden looks back on the IQ test he took when he was little. Eden, who was seven at the time, said, 'The price of a candy is 25 cents. Johnny has a dime. How many' nickel 'do you need to buy a candy? I was very confused when I read the problem.

In the problem statement, 'cent' (about 1 yen) is a unit of money in the United States, 'dime' means a dime, and 'nickel' means a nickel coin. If you knew this point, you would know that the answer was 'three', but Eden, who lived in England, didn't understand the meaning of the question itself. Similarly, the IQ test had multiple questions that could not be answered due to cultural differences, and the test lacked consideration for test takers with other cultural backgrounds.

One day, Eden was asked to answer the quiz 'Select all taxi images,' as shown in the image below. However, British taxis are generally black, and the only people who see the yellow body and realize that 'this is a taxi' are those who live in the United States or know American culture through movies. Eden points out. There are various colors of taxis in Japan as well, and it is difficult to answer smoothly without prior knowledge that 'American taxis are yellow.'



Eden argues that CAPTCHAs determine whether the respondent is 'American' rather than 'human.' He states that a system that cannot identify people who do not know American culture as 'humans' is a problem.

Many people who have the same questions as Eden have commented on this article. Regarding the IQ test problem, there were

opinions that each country has a special name for various currencies and specific coins ...



Some say that using American English such as 'crosswalk' and 'sidewalk' is also a problem. In the UK, the pedestrian crossing is called 'pedestrian crossing' and the sidewalk is called 'pavement', so even if you are asked to select 'Crosswalk' at CAPTCHA, it is difficult for British people to understand.



Also, many comments pointed out quizzes about 'fire hydrants' and 'parking meters.' I occasionally see quizzes on CAPTCHAs asking you to select an image of a fire hydrant or parking meter, as shown below.




However, '

Traffic lights are at least common, but fire hydrants ... '



'

My kids are confused by the fire hydrant and parking meter. '



Many people point out that fire hydrants and parking meters are unfamiliar, with comments such as '

I have never seen a fire hydrant before .'



In addition, comments such as '

Remember that the Internet is not America ' ...



'Nothing is more scary than seeing Americans roaming other countries thinking,'The locals are familiar with American slang and know American pop culture.'' Some

comments are offensive to the fact that they impose their culture on people in other countries.



An American user also said, 'Yellow taxis probably exist mainly in New York and Los Angeles. I live in Idaho, USA, but I have never seen a yellow taxi here.'

It said , had raised the opinion that pointed out that culture also in the United States is different.
