You might think that if your friends ask you about a girl, you should probably ask about the girl.
But a new study has found that if you do that, it will probably be wrong.
In a study published in the journal Nature Communications, scientists used video footage from a series of mysterious girl sightings in the U.S. and Britain to show that if someone asks you about the person, you will usually be mistaken.
They found that people who were asked if they had seen a girl were more likely to be correct if they did, even if they were asked about the mystery girl.
The study used a technique called “neural contagion”, which involves a brain activity being replicated in real time.
The researchers then asked the participants if they could name a mystery person from the video footage.
They did, and the people who had been asked were more than twice as likely to name the mystery person as the people whose questions were not related to the mystery.
“We are actually looking at the brain activity that causes people to recognise that there is something going on,” lead researcher Dr Peter Coyle said.
“And we’re trying to see if it could explain why that is.”
The researchers say that the method may help researchers learn more about how to identify someone who is a mystery.
It has been used before in similar research.
For instance, a study last year showed that when people were asked how much money they had made over a year, they were more accurate than people who just said they were unemployed.
The difference could be because they were talking about something that had happened in the past.
However, the researchers say the study does not prove that the neural contagion technique works for real.
“It’s not clear that neural contagions have a practical application, but we’re still very excited by the potential of this work,” Dr Coyle explained.
“The fact that we’re finding something similar to what we’ve seen in the real world, that we can recognise someone from a video is encouraging.”
