Why is research better than common sense?

Research is a science based which uses sociology as an approach while common sense is intuitionist. Common sense as people see it as true facts, it is just looked at to be true. Sociologists do research to find out what really is the truth, and sometimes, their findings reveal that the reality of a situation is the exact opposite of the common sense view. Common sense is merely assumed information, while sociology uses detailed research to come up with findings that it does. Many ideas that people believe to be true have been proven false when placed under a sociologists research. Such as, the idea that the higher the percentage of alcoholics there will be population who drink alcohol, the higher the percentage of alcoholics there will be in the population. This has been proven wrong by sociologists saying many cultures have high consumption of alcohol, but do not have higher alcoholism rates.
