Observational error is difficult to avoid, but this doesn't mean the observational subject is full helpless in front of the observational error. If observational subject continuously optimizes hisself qualities, wipe out the localization of subject to the best us the activity that observational negative impact result in, at the same time, recognize the complexity of observational object well, the respect observational environmental role, select the pooropriate method and instruments, and form the good observational habit, observational error is to may be prevented.

观察错误虽然是难以避免的，但这并不意味着观察主体在观察错误面前，是完全无能为力的，观察主体如能不断优化其自身素质，尽量消除主体局限性对观察活动造成的负面影响，同时，充分认识观察客体的复杂性，重视观察环境的作用，选择适当的观察方法和观察仪器，养成良好的观察习惯，观察错误是有可能被避免的。
