There are many reasons why you should never trust surveys. First and foremost, surveys are often inaccurate. This is because people are not always honest when they are answering questions. They may exaggerate their answers or they may simply not remember what they said.
Another reason why you should never trust surveys is because they are often conducted by people with a vested interest in the results. For example, a company may commission a survey in order to find out how popular its product is. However, the company is likely to bias the results in its favour.
Finally, you should never trust surveys because they are often based on a small sample of people. This means that they may not be representative of the population as a whole.
