Adults have pseudo concepts that can have unfortunate consequences.
We all still retain some pseudo concepts, even as adults. This is partly because we often don't have enough information at our disposal or enough need or motivation to give it more thought.
It can be, unfortunately, the bases for unreasonable generalizations. I was fired once by a highly critical and overpowering boss who had a certain physical appearance.
For years after whenever I met someone who looked similar to her, I had unjust feelings of antagonism toward that person. On two occasions, when I ignored the feelings, it became happily apparent how misplaced those generalized intuitions were. On the other hand in the third case, when I married her, I was reminded that pseudo concepts can sometimes have some validity, if only by chance.
