Deaf people have personality and psychological problems.

Due to physical defects, deaf people have a heavy sense of inferiority. Inferiority tends to make deaf people wander, isolate, lose self-confidence and lack sense of honor. Common manifestations are melancholy, pessimism and loneliness.

Most deaf people with severe inferiority complex are introverted, emotionally fragile, experienced and afraid of making a fool of themselves in public. There are several reasons for the formation of inferiority complex:

First, physical defects make deaf people unable to treat their social status correctly and feel inferior.

Second, negative self-suggestion inhibits self-confidence in communication. Facing the new environment, the wrong measurement of one's ability and the psychological burden brought by negative psychological suggestion limit one's ability and lead to failure. This result forms a kind of negative feedback, which confirms the understanding of inferiority complex and makes inferiority complex deeply rooted in the heart.

Third, self-awareness is insufficient and self-estimation is too low. Deaf people know their own advantages and disadvantages through other people's evaluation and comparison. Introverts are often willing to accept low evaluation and reflect on themselves at the same time. They are too strict with themselves, and the more strict they are, the less they feel, forming a vicious circle of negative self-evaluation.

Fourth, the impact of setbacks. Deaf and dumb people have high sensitivity and low tolerance after being frustrated. Weak setbacks give them unbearable blows and make them feel inferior.
