For Example: If sociologists try to alter somebody’s beliefs, he/she is less likely to agree with that if it is not relatable and does not sit well with his pre-existing values.

3. Comte saw dominant form of human knowledge passing through three stages: the theological, the metaphysical and the positive stage. We disagree with his idea. We think the positive and theological stage can coexist at the same time because most of the practical questions in our daily lives can be answered using scientific theories. However, science cannot answer questions about morals and ethics. 

4. It is not always possible. Sometimes it is possible to observe human behavior and recognize patterns to predict human societies and behavior. However, those predictions are not always reliable as societies are subject to social evolution. It takes form of structural differentiation through which societies become more complex and forms increasingly diverse array of social institutions.   

Positivism is defined as scientific methods which are based on empiricism and rationalism and is based on the cause and effect relationship. In social science, positivism and postpositivism emerged from the belief that human behavior can be tested and measured just like any other natural phenomenon in our surroundings.

We think this idea is impossible and dangerous because, as a human being, people don't succumb to being controlled. In fact, it is the opposite which of people will rebel against being controlled or being shaped. So, the idea of shaping the societies could sound good initially, but this could lead to a chaotic result. For example, in Thailand, two years ago, the government stand on the idea of coup d'etat which caused the citizens to rise against the government. People started protesting because they couldn't stand when the government tried to shape the society based on coup d'etat where people have no almost no basic human rights to themselves. This shows that people won't stay still, if they were being controlled or shaped into the worse idea of societies.

The three stages are the theological (religious), the metaphysical (philosophical) and the positive (scientific). We agree with this idea because each stage of Comte's ideas on dominant forms of human knowledge makes sense philosophically and scientifically

Yes, becase human societies and human behaviours are based on not only research but also academic point of views. This gives certainties to the study of human societies/behaviours because the knowledge is also based on scientific proofs. However, at some point it could get tricky. Whereas, human behaviours and societies change over time. This could cause the study or research to be inaccurate in time.

2. it is impossible because human behaviour isnt predictable and wont be subjected to being controlled by other humans like animals. it might start conflict and fights if practiced. 
3. comtes theory on the law  of  three stages consists of three stages theological(religious) metaphysical(philosophical) and positive (scientific). 
4. yes, it is possible to get knowledge from human behaviours and societies because of the common knowledge that is known to humans already. other humans may know how others think while sometimes it may be inaccurate.
