New Perfect day

Have you ever asked yourself a question if we can trust the results of different researches? You must be aware of the fact that once in a while a research is done to establish facts about something. It might be about people\s choices as far as shopping is concerned or a question about their favorite brand. Sometimes they are more serious sometimes less it depends on the situation. In my opinion it is quite obvious that researchers are working for a given company who pays for those investigations. That means that this particular company wants a certain result to be made public. This influence the results big time. I have recently seen a research about Driving theory test. From this research we were able to learn that more people than ever are passing the test. It was stated that the number of passed driving theory test have increased for about 15%. I seriously doubt it especially if we take under consideration that most of my friends had problems with passing the test for the first time. This result might be needed by driving schools to attend more people. If people think that driving theory test is easier than ever they are more likely going to sign up for it. I think researches should be done independently so that their results are not fake. How do you think?
