Reasonable Person，法律术语，普通正常人；合理的人。

a phrase used to denote a hypothetical person who exercises the qualities of attention, knowledge, intelligence,and judgment that society requires of its members for the protection of their own interest and the interests of others. This term is commonly used in torts,where the test of negligence is based on either a failure to do something that a reasonable person,guided by considerations that ordinarily regulate conduct,would do,or on the doing of something that a reasonable and prudent(wise) person would not do.

Reasonable Person，是法律上的假想人，被理想化和标准化了，具有法律所期望的一般人所应有的谨慎和理性。当判断被告行为是否谨慎时，我们要看一个"普通正常人"处在被告所处的情况下，会怎样行为。如果“普通正常人”处在被告的情况不会像被告那样行动，那么，被告的行为就有问题，就不符合“普通正常人”的标准，就可能是不谨慎的。这是一个客观的标准，它并不照顾被告的特殊弱点。不管是性急、害羞、愚蠢、健忘、反应慢、智商低还是长期粗心大意的人，都适用同样的标准。因为，不管被告人是聪明还是愚蠢，他们的行为所带来的危险是一样的，并不因为被告的能力弱而有所减轻。
