More and more often the public opinion comes interrogated daily, through an opinion poll, about numerous questions: the use of a certain product, the approval of positions assumed by political parts in territorial or national level, the attitude regarding serious problems like social integration or the respect of the weakest. If the results of the survey give a cognitive contribution on topics where the scientific debate is still open, it can be assigned an informative meaning to them; when the results can be used for strengthening, through the manifestation of an explicit consent, guidelines or decisions assumed by a company or a government, it will be assigned a confermative meaning to them. But whichever survey deserves the same credibility?  Or better, how can we distinguish between a survey offering guarantees of scientific correctness and a survey rigged up in improper way?  This lecture wants to give a contribution on these nodal aspects addressing the attention on essential requirement that a survey should have so its outcomes could be generalize, either in reading or in interpretating them.
