If a person sees a chair for the first time in his/her life, they will think that all chair is identical or very similar to this one:

They could be confused or need an explanation when they see this chair or any other chair that doesn't resemble the first chair that they saw:

Understanding and categorizing individuals despite their differences is much more harder, some data will not correlate as it is supposed to be, that's why it is natural that categories are made to be catch-all explanations. It is part of the learning. If this situation causes cognitive dissonance then we are exposed to cognitive dissonance when we learn to categorize something new. If that is the case, some level of cognitive dissonance is inevitable. According to my point of view, real cognitive dissonance occurs if a person defines/labels a chair as an apple or if a person says that chair do not exist while it exists. People type others differently, but noone is generally sure about differentiating different types as they are sure about differentiating chair from an apple. This is also natural because people are not sure about differentiating a chair from a sofa as they are sure about differentiating a chair from an apple. Can we say that a person is really suffering from cognitive dissonance if they label this chair as a sofa or vice versa? :
