单词本：paranoid

前几天读硬件安全模块文档（英文的）的时候，看到这句话：Depending on how the secure hash is used, either can be correct; but because cryptographers tend to be P3 people (Paid Professional Paranoids), the latter is generally used for the strength of a well-designed secure hash algorithm.¹

这里说密码学家通常都是P3人员，即：有偿职业偏执狂。挺有趣的称谓呀。

对我来说，这里有一个生词：paranoid [ˈpærənɔɪd] 多疑的，妄想的；患偏执症的，患妄想症的；偏执狂，妄想症患者。

似乎 -oid 结尾的词，大多是细菌、生物、疾病相关，如：

• schizoid 精神分裂的
• phylloid 叶状茎
• virusoid 拟病毒；核壳内尖病毒

也有数理化术语，如 centroid 质心。

与 paranoid 相关的单词有两个，一个是 paranoia 即妄想症、偏执症，焦虑、恐惧导致的迫害妄想（persecutory belief）。另一个是 paranoiac 与 paranoid 意思相同，不过我感觉前者更偏名词，后者更偏形容词。

例句：

• the violent defensiveness of the paranoiac is directed against all who challenge his power. 偏执狂对质疑他权力的人都抱有暴力防卫心理。
• Paranoia is an instinct or thought process that is believed to be heavily influenced by anxiety or fear, often to the point of delusion and irrationality.²
