专业提示

区分expectation与hope

expectation强调理性预期(可能实现也可能落空),而hope带有主观愿望(通常为积极向往)。例如:'I hope it rains'(希望下雨)vs 'I expect rain tomorrow'(预计明天会下雨)。

黄金法则

期望设定的黄金法则

在沟通中,明确且合理的期望设定能减少误解。过高的期望易导致失望,过低则可能降低动力。

词源

1540s, from Latin *expectationem* (nominative *expectatio*) 'anticipation, an awaiting', noun of action from past participle stem of *expectare* 'to look out for, await', literally 'to look for', from *ex-* 'out' + *spectare* 'to look' (from *specere* 'to see').

用法说明

Expectation通常指对未来结果的理性预期,而非盲目乐观。在心理学中,'expectation bias'指因先入为主的期望影响判断的现象。
