According to the conclusions drawn by Wiseman in a large number of experiments, when people with strong self-monitoring function draw a capital letter Q on their foreheads, the tail of Q faces left.

Are you an extrovert or an introvert? Use your index finger to draw a capital letter Q in front of your forehead.

Take off your index finger and think about which way the tail of the Q you just drew is facing? Towards the left or right?

"How to write Q" is a research topic of Professor Richard Wiseman, a psychologist at the University of Hertfordshire in the UK. What this psychologist, known as the "Fantasy Terminator," is best at is starting from a scientific standpoint, looking for patterns between normal and abnormal, natural and unnatural, ordinary and unusual, and using specific experiments to find the patterns. Wiseman calls his field of study “study based on subtle insights.”

The "How to Write Q" experiment can quickly test people's "self-monitoring function." According to the conclusions drawn by Wiseman in a large number of experiments, when people with strong self-monitoring function draw a capital letter Q on their foreheads, the tail of Q will be facing left. This type of person is usually an extrovert: they care very much about what others think of them, are willing to be the focus of others, and are able to adjust their behavior in a timely manner to adapt to the surrounding situation. At the same time, people with strong self-monitoring functions are also good at controlling other people and have a talent for lying - which also includes self-deception and calm deception of others.

If the capital letter Q written on one's forehead has the tail facing right, then according to Wiseman's theory, this person belongs to a category with weak self-monitoring ability. This kind of people are relatively introverted. No matter how they talk to others on the surface, they are more self-centered in their hearts. They don't care what others think of them, and are willing to remain silent when others are talking loudly. If possible, they would rather change schools, jobs, or environments than change themselves. Compared with the previous type of people with strong self-monitoring function, people with weak self-monitoring function are often better at sticking to their beliefs, and they are often unwilling to lie, even if it is a white lie. At the same time, they are not good at controlling others and changing other people's ideas.

Many people who have done this experiment have asked Professor Wiseman the same question: If I had used another hand to write the Q on my forehead, would the tail direction be different? Professor Wiseman has proved through a large number of experiments that no matter which hand was raised at the time, the tail of the Q written by the same person on the forehead will be in the same direction. So, if you want to test your self-monitoring abilities, just raise a hand and write a Q on your forehead.
