Step-by-step explanation:
Psychology is the subject that can help explain persistent and pervasive mistrust and suspiciousness, accompanied by a bias to interpret other people's motives as hostile. These symptoms are characteristic of a psychological condition called paranoid personality disorder. People with this disorder tend to be excessively distrustful and suspicious of others, often perceiving harmless actions as malevolent. This condition can have a significant impact on their relationships and daily functioning.
Research suggests that while humans have a universal tendency to be suspicious of strangers, overt physical aggression towards out-groups is not inevitable. Studies have shown that individuals with a hostile disposition are more likely to engage in antagonistic behavior towards others, which can further reinforce their hostile attitudes.
In addition to paranoid personality disorder, there are other psychological factors that can contribute to distrustful and suspicious behavior, such as attachment issues and discrimination towards specific groups. Understanding these psychological concepts can provide insights into the underlying causes and effects of persistent mistrust and suspiciousness.
