The unannounced news focuses on darkness. Society and human beings, the subjects of academic research, will communicate with the research objects, that is, they know what you are doing. For example, the previous recording pen can be used quietly. In the latter case, the recording must be approved by the subject before it can be used clearly. Of course ... if some companies recruit people with these professional backgrounds to do projects, that is another matter.
Field investigation: both society and human beings have their own investigation methods, and the two methods have similarities and differences.
Society: Theoretically speaking, generally speaking, such as "sociological research methods" and "social investigation research methods", there are also some corresponding methods in a book, such as quantitative or qualitative analysis, which usually assist the investigation. Practical operation, unprofessional, not misleading.
People: It's more about field work here. For this major, field work is like a crown gift (ten months or a year, eating, living and working with the respondents. )
Regarding effective operation, there will be corresponding courses to teach theory, first lay a good theoretical foundation and then actually enter the market (after entering the market, analyze various actual situations in detail).
The first-hand information is relative, not absolute, and the investigator himself will still have limitations, but even if these factors exist, they are still within a threshold, so the information obtained is still valuable.
Probably a process is: first, you have to do it repeatedly on paper, and then go back to paper (ethnography compilation).
If you work hard in the field, you will always get something. Even if you don't see much for a while, or if you release information to ask your predecessors, you may have other gains, or you will feel different when you look back a few years later.
Effective information is reassuring, serious and practical.
