In view of empirical data percentage of respondents choosing middle point on the bi-polar scales ranges from 3 to 50%. This shows that one cannot neglect decision, whether to include or omit this point. There is no agreement among researchers concerning this choice. Analyses presented below shows, first, to what extent insertion of the middle ("neutral") point to four-point scale changes its distribution. In the next step I try to determine which kind of these two scales is better, as considered in terms of reliability and validity. In conclusions I present interpretation which focus on the popular meaning of these scales.
