Zimbardo opens his book by stating that shyness is "a universal experience" (page 14, paperback 6th ed. 1978), that nearly 80% of those polled said they had been shy at some point in their lives, half of whom had overcome it. He establishing a range of shyness from, on one end of the range a tendency toward introversion, to mid-range shyness of situational awkwardness and feeling intimidated, to the really shy people who dread public speaking, etc. and finally the far end of shyness that "may become a severe form of neurosis." Zimbardo briefly discusses the 20% of shy people who like being shy, revealing what advantages it can have for people. Zimbardo seeks not to promote a rigid and narrow, academically approved "type" of personality, much less equate shyness with a tendency toward crime, as one reviewer claimed. At most Zimbardo implies that among those who are convicted criminals, there was a greater number who were isolated socially. Well.... Duh... One reviewer mischaracterizes Zimbardo's book by choosing to see this (rather self-evident) point as meaning that shy people have a propensity toward crime. What Zimbardo actually says that shyness in the extreme, can be a contributing factor to the degradation of one's mental health, which, if unchecked, can in some cases continue to deeper pathologies. And at that level of pathology, should there be no means of healthy release of the internal stresses and tensions of such pathology, in some cases can lead to violence against self or another person. There are a lot of contingencies that one reviewer chose to ignore, resulting in a logic by which getting out of bed in the morning, an act that all killers do, indicates a propensity to murder. Let's not misread Zimbardo, whose "...main interest is only in helping shy people remove barriers to their greater freedom, to their fuller participation in life, and to their personal sense of worth and mastery" (120).
