Can polygraphs test whether a relationship is real or fake? Young couples prefer it

        In the popular American TV series "Lietome", "When an average person talks to others, he or she will tell 3 lies every 10 minutes on average." This is regarded as a classic by many people, especially the legendary "fool in love". Recently, a reporter found that a small gadget called "electric lie detector" which costs less than 100 yuan has been searched hotly on Taobao.

Can it really reveal the truth of what was said? After investigation, the reporter concluded: NO! However, many young men and women still showed great curiosity about it.

【Seller】

More than 10 polygraphs sold in one day

In Taobao's popular search list in the middle and early part of this month, "electric lie detector" jumped to around 35th place, and the best-selling online store sold more than 30 units in three days.

The reporter searched for "lie detector" on Taobao and found more than 300 items, all labeled as "electric lie detectors" with prices ranging from 60 to more than 90 yuan. The seller detailed its usage in the product introduction: first put your right hand in the finger slot of the "lie detector", press the Reset button, keep your finger still, and then press the "Analyser" button, the machine will start to read some of your data for comparison when the test starts.

After each question, press the "Analyser" button. The polygraph will measure whether you are lying and the level of lying. If you are lying, there will be LED indicators to show the degree of your lying. There are 5 levels of indicators in total, 3 green and 2 red. They will light up as the test progresses, and the more indicators light up, the bigger you are lying. If you lie directly or give an unacceptable answer, or distort the facts, all the indicators will light up and you will be punished by electric shock.

However, most sellers state in their product descriptions: "This is just a game console for entertainment."

A random try caused a family storm

"Brush your teeth before bed?"

"Sometimes I brush, sometimes I don't." - (via)

"Have you ever had sex before marriage?"

"No" - (hiss, electric shock)

…

In the past two days, the buyer "Jue Lenglianqing" spent 85 yuan to buy a lie detector on Taobao, and started testing her husband Nemo after returning home.

"The results show that this lie detector is quite accurate. It's not bad to have one at home!" "Jue Leng Lian Qing" told the reporter, "I just found out that he usually smokes a pack of cigarettes a day at work. He lied to me and said he only smoked a few cigarettes. I came back to deal with him!" Later, "Jue Leng Lian Qing" yelled at "Nemo" on MSN about the "pack of cigarettes": "You don't have to come back. I'm so mad. I'm going home!"

Even worse than "Nemo", the reporter learned that Taobao user "kt" broke up with his girlfriend because of a lie detector test.

A few days ago, he saw a seller's advertisement saying "give a lie detector to show sincerity", so "kt" bought one for his girlfriend, but the test results showed that kt lied in most of the questions, which almost ruined their relationship of many years. Although "kt" and his girlfriend thought it was a joke at the beginning, they began to doubt it slowly over time, "there are always some small conflicts, and the 'lie detector' adds fuel to the fire", and once after a big fight, his girlfriend proposed to break up. "kt" is still trying to persuade his girlfriend, hoping to explain the misunderstanding between the two.

【Netizen】

Don't take this stuff seriously.

The reporter interviewed several buyers who bought lie detectors through Taobao's chat tool Wangwang. Most buyers have an entertaining and rational attitude towards lie detectors. Buyer "wujiang" told the reporter: "Don't expect this thing to test anything. The world is full of love, which is better than anything else." Some buyers raised some questions and suggestions. Buyer "Tongzhongbiao" said: "The seller should check before selling the things. We should take our questions seriously. The seller should be the one who needs to use the lie detector the most." Some buyers questioned its safety. Buyer "enenya10" said: "It is charged. I dare not play with it after buying it."

Is the instrument safe when it is powered?

Not suitable for patients with heart disease

The reporter saw that the so-called "lie detector" sold online is connected by three No. 7 batteries. Theoretically, it generates a voltage of about 1.5V. According to scientific common sense, the voltage that the human body can withstand is 36V. Dr. Chen Biao of a tertiary hospital under the Second Military Academy told reporters that in theory, it is safe, but people who have certain interference with electronic equipment such as pacemakers, heart diseases, epilepsy and other similar diseases, or people who react strongly to electric shocks are not suitable for "lie detection".

Is it illegal to buy a polygraph?

There is no ban on the sale of polygraph equipment

When we mention polygraphs, we often think of the interrogation scenes in TV dramas. Can ordinary people buy and sell this kind of equipment commonly used by the police? In this regard, relevant personnel from the Municipal Public Security Bureau told reporters that professional polygraphs are not exclusively used by public security departments. Lawyer Tian Bo from Shanghai Haizhong Law Firm told reporters that according to current laws, polygraphs are not banned from sale, and according to his judgment of the polygraphs sold online, they are not professional equipment, but just toys. People should mainly use them for entertainment and not take them too seriously.
