There is a problem of "skull deformity" in police recruitment and physical examination.

Skull deformity generally refers to the disability caused by trauma, including obvious deformation of skull, bone window (that is, hole in skull) and skull defect. Think too much, there is no problem at all.

Although I am only an academic researcher in neuroscience, I can tell you that, in a scientific sense, a person's intelligence is not necessarily related to the size of his head, but mainly related to his personality, knowledge and experience, and he can continuously improve his intelligence level the day after tomorrow! The reason why some people unilaterally say that IQ is innate is because a person's personality has been formed in early childhood and it is difficult to change the day after tomorrow, but they have not seen other factors that affect intelligence, that is, knowledge and experience. Besides, everyone's personality is given by God, and there is nothing wrong with it. Everyone has his own advantages and disadvantages, so what?

Psychologically, I feel you are a little insecure, brother. If you don't doubt yourself, you won't believe other people's stories. Like farting, that statement is not scientific at all, just like astrology, divination and fortune telling. Be confident and calm. Whatever you do will bring you good luck. You can be a good policeman!
