In my field of study which is geology, most of the writing one is research based. Much of the writing comes from data in the field study. As a geologist you go out into the field and record data on rocks, water contamination or even volcanic activity. The challenge about this writing style is that it must include relevant information that correlates with your data. There is no opinion in your writing and must all be factual information. It is similar to some papers I have written such as research papers. All the material is based on fact rather than opinion. What is bad about this style of writing is that it allows very little freedom or flexibility in the writing. It is composed on a very ridged scale that includes data from the field and an accurate analysis of the data retrieved. The good thing about this writing is that you know that what you reading is the truth. Ther is no false information and it is all relevant.
