1 确实，当观察同一事物时，不同的人有不同的观点

2 观察的对象都是客观的。任何观察都是借助科学仪器，用主观的思想分析客观事物或数据。因此，科学研究尽量做到研究客体的信息足够准确和可靠,测量必须尽可能客观。应让客观主导研究。
在测量工具诞生前，人们依赖感官观察并获取信息
3 人类的认知能力是有限的，我们不能保证现在的理论就是真理。但是，科学研究就是在这样的过程中不断完善。按照作者的说法，人类就没有真正了解的事物。
4 当然，当观察者过于看重他们所希望发现的结果，而忽略他们不希望的，观察错误就会发生。这种情况需要避免

Observations are objective or subjective? Science has been developed under a circle of “ establish-oppugn-overturn” since our human being
started the investigation and analysis of the universe. Of course, every scientist strive for objectivity,but what exactly does “objectivity” mean? There have been quite a lot debate about objectivity. And I believe, of course, there is no such thing as purely objective observation, but every research of human being should respect the objectivity of the nature.

Indeed, different people have different opinions when they observe the same object. We can not escape the biases due to our personal experiences, modes of thinking, interests, background,or even race and gender.

but I think, it is likely for the observers to incorporate some of their expectations and desires unconsciouly in to the observation, which is understandable and should not to be blamed. Moreover, different opinions should not be definitely avoided, for that is the source of diversity in scientific study.

Then what is observation? And what does an objective observation really means? The definition of observation in encyclopedia, and I paraphased, is to gain the knowledge from the outside world through the senses, or the recording of the data using scientific instruments. Meaning all the observations require objective proof falls under the observers’objective thinking. Senses are limited, and are subject to errors in perception such as optical illusions. So we need scientific instruments to magnify human powers of observation. To sum, every observation should respect the objectivity of the matter. It is vitally important for science that the information and objects we are studying about the world around us must be as accurate and as reliable as possible. And at the same time, measurements which play as the source of these information also have to be as objective as possible. Before the invention of measuring tools, human have to relay the source of information on their senses. The consequence of this was the lack of a rigorous science. Brownian movement, as we all know, is objective in nature, many scientists have devoted to the observation, Perrin, Einstein. Nowadays, this theory is wildly used in many aspects of scientific research.

According to the author’s assertion, there are nothing we can truly know, which is unresonable. Of course, we dare not to say that what we have today are the truth, because the human cognitive ability is limited in the process of its development. However, that is why we are engage in scientific observations without a stop from generation to generation. For example, we realised that the classical mechanics has limitation after the establish of theory of relativity. So we should have faith in the observations and its objectivity. However, the observer bias is error when they overemphasize behavior they expect to find and fail to notice behavior they do not expect. That is to say, the observers should see the meaning of the behavior of the object itself, rather than what the behavior means to them.

From the analyses made above, I strongly commit to the notion that maybe we can not observe something purely objective, but we must make the observations as objective as possible, to let the subjective thinking serve for the objective observations.And that is the attitude of all the scientific researches. In a word, this complex issue depend on a dialectic perspective.
