Some criticisms of Carl Roger's theory are: - He considers that parents must show unconditional approval to their children, however, there are children with very harmful behaviors to whom approval cannot be shown. - His concept of human nature is that it always tends to good and healthy, and it has been proven that this is not always the case. - Considers that a relationship of unconditional positive respect should be shown in the therapeutic relationship, but there has been a lot of criticism if the therapists can or should do it in all cases. For example, with very aggressive patients.
