Insider vs. Outsider Perspectives

1. The benefits of having two different perspectives is that you get two different views of the same thing. An inside view provides a more personal view that is more closely associated with the culture that is being observed. An outside view provides a more scientific and open approach. The insider perspective is better because you're seeing what is actually believed by the people and are observing on a more personal level.

2. Acknowledging your biases instead of being objective is a rule for conducting an ethnography because you are from a different culture and it's impossible to pretend like you don't have different views and judgments about the people.
Having an informant is a rule so you can get a first-person account of the culture instead of gaining knowledge only through observation. They may tell you things different than what you could have observed.
Being up-front about what you're studying is a rule because even though the people are different from you, you need to be honest. This honesty will keep them from viewing you as an intruder or enemy. This rule also goes with the informant rule because by telling people what you're studying, some may be willing to help and inform you.
