Excuse me: What is the relationship between IQ and fingerprints?

There are many folk sayings about "fighting", such as: "One fight is poor, two fights are rich, three fights and four fights sell tofu, five fights and six fights open pawn shops, seven fights and eight fights sit (be an official), and nine fights and ten fights enjoy happiness." Experts from the fingerprint museum told reporters that it is not without scientific basis.

Our fingerprints are three-dimensional, because they are uneven, so there are lines. The convex line is called mastoid line, and the concave place is called small furrow. According to the central pattern and the shape of triangle, fingerprints can be roughly divided into three types: bow type, dustpan type and bucket type. Some scholars' research shows that from bow to bucket, the pattern structure is more and more complex, and the IQ level is often higher.

There is a folk saying that concentric circles in fingerprints are "stupid patterns", and some experts have made a special investigation. The probability of students in the juvenile class of the University of Science and Technology of China appearing this fingerprint is lower than that of ordinary people; Left-handed people are generally considered to have higher IQ, and the survey found that the incidence of concentric circles is also significantly lower than that of the general population.
